Where To Start In DIY Electronics?

Hardware Hacking 301

pyrosine writes "I've been thinking about this for a while and have no idea where to start. I have little or no previous experience in electronics — just what is covered in GCSE physics (wiring a plug and resistors — not much, I know). The majority of my interest lies in the wireless communication side of the field — i.e. ham radios and CB — but I am also interested in how many things work, one example being speakers, simply to better understand it. I would preferably like to start with some form of practical guide rather than learning the theory first, but where I would find such a walkthrough eludes me."

Gettng Started in Electronics [forrestmims.com] . It takes you through everything from basic soldering to building logic circuits, oscillators, amplifiers. His "mini notebooks" are great too.

Once you have the basics down you will probably want to get into microcontrollers. There are a lot of ways to go here depending on how much time you want to spend wiring things up yourself, and your comfort level with software. You might start with the very popular PIC. Although the architecture is a bit long in the tooth and is a poor target for C, there loads of example projects for it so it's easy to learn. There are also many high-level building blocks (Basic stamp etc) that can get you up and running quickly. If you have sophisticated software needs, you'll want a more modern micro with better tools - check out Atmel or TI.

Eventually you will need a more formal treatment if you want to design your own circuits. I consider The Art of Electronics [harvard.edu] to be the bible here - it is thorough but also very practical and you will find it has specific solutions for many everyday engineering problems. It has been a great investment, and one of the better worn books on my shelf. Have fun!

I was about to leave a comment saying "Getting Started in Eletronics" - you beat me to it. Best thing I could ever recommend to anyone just starting out. Amazing book. My book was getting old so I scanned all the pages into a PDF, only to find on BitTorrent that someone beat me to it!!!

I started with a marine radio receiver kit from HeathKit. Don't know if they are available anymore, but it was more engrossing than a book would have been. After that project I was able to approach the written material with some context for understanding. I guess it depends on what sort of learning method appeals to the poster.

Oooops. Sorry guys. The wife has that idiot boob tube playing, and I thought I was taking dictation for some reason. ;^)

Art of Electronics is a good book. I am an EE and I have it and would replace it if stolen.

I probably wouldn't replace the other one if I owned it and it was stolen.

Art of electronics (2, Interesting)

It's a nice reference. Once in a while you just have to get right back to the basics and remind yourself how some common BJT circuits such as current mirrors work. Ditto with basic opamp circuits.

Depending what's understood with "electronics" it's big and sprawling subject with many sub-disciplines. You can get into EMI quagmire and never really come out of it, for example.

I was interviewed with one company where "cad heads" and designers are quite separate with layout designers being the less appreciated job.

In any case, there are many, many things to learn and you only become really good when years go by and you accumulate knowledge. You do, however, probably become good only in subset of things you've worked with.

For example. Mosfets are voltage controlled devices and you do not have to worry about power to the gate, right? Wrong. The gate charge, while very small _does_ add up hugely in SMPS circuits and such when you're charging and discharging that small capacitor 100000 times a second or so.

GNAA REBORN UNDER NEW LEADERSHIP

DiKKy Heartiez - Berlin, Norway

President timecop of the GNAA has died today. He died at the age of 55 from excessive lulz in his apartment in Tokyo, Japan while watching faggot cartoons of preteen girls beeing raped by giant testicles. The world will remember him as a total faggot douchebag who had the opportunity to unite the best trolls seen upon the face of the internet into one special hardcore machine of destruction, unfortunately he failed, instead devoting his internet carreer to animu. Although he died like a true hero he will be forever remembered as a total failure.

In the wake of his death the GNAA is thought to perish like all the other so called trolling organizations. The writing is on the wall, they say. The GNAA smells worse than BSD, they say.They have said this for a long time. The GNAA has lived, with a very faint pulse, for years.

DIKKY HEARTIEZ CLAIMS THE PRESIDENCY OF THE GNAA!!!!!!!

With the death of timecop still shocking our chats, not many are able to see ahead. But there is one visionary Nord who has great plans for the new GNAA.
"Under my leadership the GNAA will become the new home of all trolls on the internet. The GNAA will regain its old strength and will be feared by bloggers and jews alike. The time for CHANGE is now." DiKky HearTiez told a shocked audience outside the Gary Niger Memorial Plaza, Nigeria, earlier today. The GNAA will move its Internet Relayed Communications to a new location, following reports of a massive "Distributed Denial Of Service" attack on its previous location, making it unreliable.
"Our operatives are in need of a robust and safe communications service with can_flood for everyone." An anonymous source at the GNAA Black Ops department told reporters at the same conference.

KLULZ supports DiKKy Heartiez presidency!

The infamous KLULZ internet radio station supports DiKKy Heartiez for the new GNAA president.
"KLULZ is behind him 100% and will be broadcasting his speeches and support him in every way possible, we wish him the best of luck and an outstanding presidency. May many blogs burn under DiKky Hearties." This was stated by KLULZ Operations Manager and Gay Nigger g0sp when asked to comment on KLULZ involvement.

About President timecop

DEAD.

About DiKKy HearTiez

The world famous internet nord from Norway LOL HY living in a fjord LOL HY. Currently the new President of the new GNAA. He is also a radiodj on KLULZ and active in many irc chats. Known for several epic trolls in his time. Led the GNAA operation Intel Crapflood 21, who succesfully made GNAA owners of the biggest thread on Slashdot until fixed by admins. Also deeply involved in the war on blogs, and is the one who provided JesuitX with the real screenshots of Faggintosh Leopard. His leadership abilities, high iq and instoppable urge to troll, coupled with his fat Norwegian welfare check will enable him to become the best President the GNAA ever had.

It has come to my attention that the entire Linux community is a hotbed of so called 'alternative sexuality', which includes anything from hedonistic orgies to homosexuality to paedophilia.

What better way of demonstrating this than by looking at the hidden messages contained within the names of some of Linux's most outspoken advocates:

  • Linus Torvalds [microsoft.com] is an anagram of slit anus or VD 'L,' clearly referring to himself by the first initial.
  • Richard M. Stallman [archive.org], spokespervert for the Gaysex's Not Unusual 'movement' is an anagram of mans cram thrill ad.
  • Alan Cox [microsoft.com] is barely an anagram of anal cox which is just so filthy and unchristian it unnerves me.

I'm sure that Eric S. Raymond, composer of the satanic homosexual [goatse.fr] propaganda diatribe The Cathedral and the Bizarre, is probably an anagram of something queer, but we don't need to look that far as we know he's always shoving a gun up some poor little boy's rectum. Update: Eric S. Raymond is actually an anagram for secondary rim and cord in my arse. It just goes to show you that he is indeed queer.

Update the Second: It is also documented that Evil Sicko Gaymond is responsible for a nauseating piece of code called Fetchmail [microsoft.com], which is obviously sinister sodomite slang for 'Felch Male' -- a disgusting practise. For those not in the know, 'felching' is the act performed by two perverts wherein one sucks their own post-coital ejaculate out of the other's rectum. In fact, it appears that the dirty Linux faggots set out to undermine the good Republican institution of e-mail, turning it into 'e-male.'

As far as Richard 'Master' Stallman goes, that filthy fudge-packer was actually quoted [salon.com] on leftist commie propaganda site Salon.com as saying the following: 'I've been resistant to the pressure to conform in any circumstance,' he says. 'It's about being able to question conventional wisdom,' he asserts. 'I believe in love, but not monogamy,' he says plainly.

And this isn't a made up troll bullshit either! He actually stated this tripe, which makes it obvious that he is trying to politely say that he's a flaming homo [comp-u-geek.net] slut [rotten.com]!

Speaking about 'flaming,' who better to point out as a filthy chutney ferret than Slashdot's very own self-confessed pederast Jon Katz. Although an obvious deviant anagram cannot be found from his name, he has already confessed, nay boasted of the homosexual [goatse.fr] perversion of corrupting the innocence of young children [slashdot.org]. To quote from the article linked:

'I've got a rare kidney disease,' I told her. 'I have to go to the bathroom a lot. You can come with me if you want, but it takes a while. Is that okay with you? Do you want a note from my doctor?'

Is this why you were touching your penis [rotten.com] in the cinema, Jon? And letting the other boys touch it too?

We should also point out that Jon Katz refers to himself as 'Slashdot's resident Gasbag.' Is there any more doubt? For those fortunate few who aren't aware of the list of homosexual [goatse.fr] terminology found inside the Linux 'Sauce Code,' a 'Gasbag' is a pervert who gains sexual gratification from having a thin straw inserted into his urethra (or to use the common parlance, 'piss-pipe'), then his homosexual [goatse.fr] lover blows firmly down the straw to inflate his scrotum. This is, of course, when he's not busy violating the dignity and copyright of posters to Slashdot by gathering together their postings and publishing them en masse to further his twisted and manipulative journalistic agenda.

Sick, disgusting antichristian perverts, the lot of them.

In addition, many of the Linux distributions (a 'distribution' is the most common way to spread the faggots' wares) are run by faggot groups. The Slackware [redhat.com] distro is named after the 'Slack-wear' fags wear to allow easy access to the anus for sexual purposes. Furthermore, Slackware is a close anagram of claw arse, a reference to the homosexual [goatse.fr] practise of anal fisting. The Mandrake [slackware.com] product is run by a group of French faggot satanists, and is named after the faggot nickname for the vibrator. It was also chosen because it is an anagram for dark amen and ram naked, which is what they do.

Another 'distro,' (abbrieviated as such because it sounds a bit like 'Disco,' which is where homosexuals [goatse.fr] preyed on young boys in the 1970s), is Debian, [mandrake.com] an anagram of in a bed, which could be considered innocent enough (after all, a bed is both where we sleep and pray), until we realise what other names Debian uses to describe their foul wares. 'Woody' is obvious enough, being a term for the erect male penis [rotten.com], glistening with pre-cum. But far sicker is the phrase 'Frozen Potato' that they use. This filthy term, again found in the secret homosexual [goatse.fr] 'Sauce Code,' refers to the solo homosexual [goatse.fr] practice of defecating into a clear polythene bag, shaping the turd into a crude approximation of the male phallus, then leaving it in the freezer overnight until it becomes solid. The practitioner then proceeds to push the frozen 'potato' up his own rectum, squeezing it in and out until his tight young balls erupt in a screaming orgasm.

And Red Hat [debian.org] is secret homo [comp-u-geek.net] slang for the tip of a penis [rotten.com] that is soaked in blood from a freshly violated underage ringpiece.

The fags have even invented special tools to aid their faggotry! For example, the 'supermount' tool was devised to allow deeper penetration, which is good for fags because it gives more pressure on the prostate gland. 'Automount' is used, on the other hand, because Linux users are all fat and gay, and need to mount each other [comp-u-geek.net] automatically.

The depths of their depravity can be seen in their use of 'mount points.' These are, plainly speaking, the different points of penetration. The main one is obviously/anus, but there are others. Militant fags even say 'there is no/opt mount point' because for these dirty perverts faggotry is not optional but a way of life.

More evidence is in the fact that Linux users say how much they love `man`, even going so far as to say that all new Linux users (who are in fact just innocent heterosexuals indoctrinated by the gay propaganda) should try out `man`. In no other system do users boast of their frequent recourse to a man.

Other areas of the system also show Linux's inherent gayness. For example, people are often told of the 'FAQ,' but how many innocent heterosexual Windows [amiga.com] users know what this actually means. The answer is shocking: Faggot Anal Quest: the voyage of discovery for newly converted fags!

Even the title 'Slashdot [geekizoid.com]' originally referred to a homosexual [goatse.fr] practice. Slashdot [kuro5hin.org] of course refers to the popular gay practice of blood-letting. The Slashbots, of course are those super-zealous homosexuals [goatse.fr] who take this perversion to its extreme by ripping open their anuses, as seen on the site most popular with Slashdot users, the depraved work of Satan, http://www.eff.org/ [eff.org].

The editors of Slashdot [slashduh.org] also have homosexual [goatse.fr] names: 'Hemos' is obvious in itself, being one vowel away from 'Homos.' But even more sickening is 'Commander Taco' which sounds a bit like 'Commode in Taco,' filthy gay slang for a pair of spreadeagled buttocks that are caked with excrement [pboy.com]. (The best form of lubrication, they insist.) Sometimes, these 'Taco Commodes' have special 'Salsa Sauce' (blood from a ruptured rectum) and 'Cheese' (rancid flakes of penis [rotten.com] discharge) toppings. And to make it even worse, Slashdot [notslashdot.org] runs on Apache!

The Apache [microsoft.com] server, whose use among fags is as prevalent as AIDS, is named after homosexual [goatse.fr] activity -- as everyone knows, popular faggot band, the Village People, featured an Apache Indian, and it is for him that this gay program is named.

And that's not forgetting the use of patches in the Linux fag world -- patches are used to make the anus accessible for repeated anal sex even after its rupture by a session of fisting.

To summarise: Linux is gay. 'Slash -- Dot' is the graphical description of the space between a young boy's scrotum and anus. And BeOS [apple.com] is for hermaphrodites and disabled 'stumpers.'

FEEDBACK

What worries me is how much you know about what gay people do. I'm scared I actually read this whole thing. I think this post is a good example of the negative effects of Internet usage on people. This person obviously has no social life anymore and had to result to writing something as stupid as this. And actually take the time to do it too. Although... I think it was satire.. blah.. it's early. -- Anonymous Coward, Slashdot

Well, the only reason I know all about this is because I had the misfortune to read the Linux 'Sauce code' once. Although publicised as the computer code needed to get Linux up and running on a computer (and haven't you always been worried about the phrase 'Monolithic Kernel'?), this foul document is actually a detailed and graphic description of every conceivable degrading perversion known to the human race, as well as a few of the major animal species. It has shocked and disturbed me, to the point of needing to shock and disturb the common man to warn them of the impending homo [comp-u-geek.net]-calypse which threatens to engulf our planet.

You must work for the government. Trying to post the most obscene stuff in hopes that slashdot won't be able to continue or something, due to legal woes. If i ever see your ugly face, i'm going to stick my fireplace poker up your ass, after it's nice and hot, to weld shut that nasty gaping hole of yours. -- Anonymous Coward, Slashdot

Doesn't it give you a hard-on to imagine your thick strong poker ramming it's way up my most sacred of sphincters? You're beyond help, my friend, as the only thing you can imagine is the foul penetrative violation of another man. Are you sure you're not Eric Raymond? The government, being populated by limp-wristed liberals, could never stem the sickening tide of homosexual [goatse.fr] child molesting Linux advocacy. Hell, they've given NAMBLA free reign for years!

you really should post this logged in. i wish i could remember jebus's password, cuz i'd give it to you. -- mighty jebus [slashdot.org], Slashdot

Thank you for your kind words of support. However, this document shall only ever be posted anonymously. This is because the 'Open Sauce' movement is a sham, proposing homoerotic cults of hero worshipping in the name of freedom. I speak for the common man. For any man who prefers the warm, enveloping velvet folds of a woman's vagina [bodysnatchers.co.uk] to the tight puckered ringpiece of a child. These men, being common, decent folk, don't have a say in the political hypocrisy that is Slashdot culture. I am the unknown liberator [hitler.org].

ROLF LAMO i hate linux FAGGOTS -- Anonymous Coward, Slashdot

We shouldn't hate them, we should pity them for the misguided fools they are... Fanatical Linux zeal-outs need to be herded into camps for re-education and subsequent rehabilitation into normal heterosexual society. This re-education shall be achieved by forcing them to watch repeats of Baywatch until the very mention of Pamela Anderson [rotten.com] causes them to fill their pants with healthy heterosexual jism [zillabunny.com].

Actually, that's not at all how scrotal inflation works. I understand it involves injecting sterile saline solution into the scrotum. I've never tried this, but you can read how to do it safely in case you're interested. (Before you moderate this down, ask yourself honestly -- who are the real crazies -- people who do scrotal inflation, or people who pay $1000+ for a game console?) -- double_h [slashdot.org], Slashdot

Well, it just goes to show that even the holy Linux 'sauce code' is riddled with bugs that need fixing. (The irony of Jon Katz not even being able to inflate his scrotum correctly has not been lost on me.) The Linux pervert elite already acknowledge this, with their queer slogan: 'Given enough arms, all rectums are shallow.' And anyway, the PS2 [xbox.com] sucks major cock and isn't worth the money. Intellivision forever!

dude did u used to post on msnbc's nt bulletin board now that u are doing anti-gay posts u also need to start in with anti-black stuff too c u in church -- Anonymous Coward, Slashdot

For one thing, whilst Linux is a cavalcade of queer propaganda masquerading as the future of computing, NT [linux.com] is used by people who think nothing better of encasing their genitals in quick setting plaster then going to see a really dirty porno film, enjoying the restriction enforced onto them. Remember, a wasted arousal is a sin in the eyes of the Catholic church [atheism.org]. Clearly, the only god-fearing Christian operating system in existence is CP/M -- The Christian Program Monitor. All computer users should immediately ask their local pastor to install this fine OS onto their systems. It is the only route to salvation.

Secondly, this message is for every man. Computers know no colour. Not only that, but one of the finest websites in the world is maintained by a Black Man [stileproject.com] . Now fuck off you racist donkey felcher.

And don't forget that slashdot was written in Perl, which is just too close to 'Pearl Necklace' for comfort.... oh wait; that's something all you heterosexuals do.... I can't help but wonder how much faster the trolls could do First-Posts on this site if it were redone in PHP... I could hand-type dynamic HTML pages faster than Perl can do them. -- phee [slashdot.org], Slashdot

Although there is nothing unholy about the fine heterosexual act of ejaculating between a woman's breasts, squirting one's load up towards her neck and chin area, it should be noted that Perl [python.org] (standing for Pansies Entering Rectums Locally) is also close to 'Pearl Monocle,' 'Pearl Nosering,' and the ubiquitous 'Pearl Enema.'

One scary thing about Perl [sun.com] is that it contains hidden homosexual [goatse.fr] messages. Take the following code: LWP::Simple -- It looks innocuous enough, doesn't it? But look at the line closely: There are two colons next to each other! As Larry 'Balls to the' Wall would openly admit in the Perl Documentation, Perl was designed from the ground up to indoctrinate it's programmers into performing unnatural sexual acts -- having two colons so closely together is clearly a reference to the perverse sickening act of 'colon kissing,' whereby two homosexual [goatse.fr] queers spread their buttocks wide, pressing their filthy torn sphincters together. They then share small round objects like marbles or golfballs by passing them from one rectum to another using muscle contraction alone. This is also referred to in programming 'circles' as 'Parameter Passing.'

And PHP [perl.org] stands for Perverted Homosexual Penetration. Didn't you know?

Thank you for your valuable input on this. I am sure you will be never forgotten. BTW: Did I mention that this could be useful in terraforming Mars? Mars rulaa. -- Eimernase [slashdot.org], Slashdot

Well, I don't know about terraforming Mars, but I do know that homosexual [goatse.fr] Linux Advocates have been probing Uranus for years.

That's inspiring. Keep up the good work, AC. May God in his wisdom grant you the strength to bring the plain honest truth to this community, and make it pure again. Yours, Cerberus. -- Anonymous Coward, Slashdot

*sniff* That brings a tear to my eye. Thank you once more for your kind support. I have taken faith in the knowledge that I am doing the Good Lord [atheism.org]'s work, but it is encouraging to know that I am helping out the common man here.

However, I should be cautious about revealing your name 'Cerberus' on such a filthy den of depravity as Slashdot. It is a well known fact that the 'Kerberos' documentation from Microsoft is a detailed manual describing, in intimate, exacting detail, how to sexually penetrate a variety of unwilling canine animals; be they domesticated, wild, or mythical. Slashdot posters have taken great pleasure in illegally spreading this documentation far and wide, treating it as an 'extension' to the Linux 'Sauce Code,' for the sake of 'interoperability.' (The slang term they use for nonconsensual intercourse -- their favourite kind.)

In fact, sick twisted Linux deviants are known to have LAN parties, (Love of Anal Naughtiness, needless to say.), wherein they entice a stray dog, known as the 'Samba Mount,' into their homes. Up to four of these filth-sodden blasphemers against nature take turns to plunge their erect, throbbing, uncircumcised members, conkers-deep, into the rectum, mouth, and other fleshy orifices of the poor animal. Eventually, the 'Samba Mount' collapses due to 'overload,' and needs to be 'rebooted.' (i.e., kicked out into the street, and left to fend for itself.) Many Linux users boast about their 'uptime' in such situations.

Inspiring stuff! If only all trolls were this quality! -- Anonymous Coward, Slashdot

If only indeed. You can help our brave cause by moderating this message up as often as possible. I recommend '+1, Underrated,' as that will protect your precious Karma in Metamoderation [slashdot.org]. Only then can we break through the glass ceiling of Homosexual Slashdot Culture. Is it any wonder that the new version of Slashcode has been christened 'Bender'???

If we can get just one of these postings up to at least '+1,' then it will be archived forever! Others will learn of our struggle, and join with us in our battle for freedom!

It's pathetic you've spent so much time writing this. -- Anonymous Coward, Slashdot

I am compelled to document the foulness and carnal depravity [catholic.net] that is Linux, in order that we may prepare ourselves for the great holy war that is to follow. It is my solemn duty to peel back the foreskin of ignorance and apply the wire brush of enlightenment.

As with any great open-source project, you need someone asking this question, so I'll do it. When the hell is version 2.0 going to be ready?!?! -- Anonymous Coward, Slashdot

I could make an arrogant, childish comment along the lines of 'Every time someone asks for 2.0, I won't release it for another 24 hours,' but the truth of the matter is that I'm quite nervous of releasing a 'number two,' as I can guarantee some filthy shit-slurping Linux pervert would want to suck it straight out of my anus before I've even had chance to wipe.

I desperately want to suck your monolithic kernel, you sexy hunk, you. -- Anonymous Coward, Slashdot

I sincerely hope you're Natalie Portman [archive.org].

Dude, nothing on slashdot larger than 3 paragraphs is worth reading. Try to distill the message, whatever it was, and maybe I'll read it. As it is, I have to much open source software to write to waste even 10 seconds of precious time. 10 seconds is all its gonna take M$ to whoop Linux's ass. Vigilence is the price of Free (as in libre -- from the fine, frou frou French language) Software. Hack on fellow geeks, and remember: Friday is Bouillabaisse day except for heathens who do not believe that Jesus died for their sins. Those godless, oil drench, bearded sexist clowns can pull grits from their pantaloons (another fine, fine French word) and eat that. Anyway, try to keep your message focused and concise. For concision is the soul of derision. Way. -- Anonymous Coward, Slashdot

What the fuck?

I've read your gay conspiracy post version 1.3.0 and I must say I'm impressed. In particular, I appreciate how you have managed to squeeze in a healthy dose of the latent homosexuality you gay-bashing homos [comp-u-geek.net] tend to be full of. Thank you again. -- Anonymous Coward, Slashdot

Well bugger me!

ooooh honey. how insecure are you!!! wann a little massage from deare bruci. love you -- Anonymous Coward, Slashdot

Fuck right off!

IMPORTANT: This message needs to be heard (Not HURD [linux.org], which is an acronym for 'Huge Unclean Rectal Dilator') across the whole community, so it has been released into the Public Domain [icopyright.com]. You know, that licence that we all had before those homoerotic crypto-fascists came out with the GPL [apple.com] (Gay Penetration License) that is no more than an excuse to see who's got the biggest feces-encrusted [rotten.com] cock. I would have put this up on Freshmeat [adultmember.com], but that name is known to be a euphemism for the tight rump of a young boy.

Come to think of it, the whole concept of 'Source Control' unnerves me, because it sounds a bit like 'Sauce Control,' which is a description of the homosexual [goatse.fr] practice of holding the base of the cock shaft tightly upon the point of ejaculation, thus causing a build up of semenal fluid that is only released upon entry into an incision made into the base of the receiver's scrotum. And 'Open Sauce' is the act of ejaculating into another mans face or perhaps a biscuit to be shared later. Obviously, 'Closed Sauce' is the only Christian thing to do, as evidenced by the fact that it is what Cathedrals are all about.

I sat naked on the bench in the health club locker room, staring at the tiles on the floor between my feet, but really looking at nothing. I was waiting for Barack to decide to come up and talk to me. He was this muscular teenage nigger who frequented the club and had ruined my life in the last few weeks. I was ordered to sit naked on the bench without a towel or anything to cover my nakedness. I had to keep my legs spread and my cock and balls visible for the anyone in the locker room who wanted a look. I knew instantly that it had been a mistake to sign up at the inner city health club which was eighty percent black, but it was near my house and cheap which was even more important.

The harassment had started on my first visit. Dark skinned, muscular black boys bouncing around the locker room with their huge dicks and pendulous sacks of balls swinging, high fiving each other and laughing and rapping, and there I was, this moderately built white guy of thirty two.

I will never forget coming back from the shower and one chocolate skinned thug of about eighteen let out a "weeeeeeeow" kind of sound and then said very loudly to me, loudly enough for all his pals to hear, "White man, how the hell can you fuck wit such a small dick?" They all roared with laughter and I turned bright red. Before I left that first time, I met Barack. He eased up to me while I was packing my gym bag. He is one good looking darkie, I will say that for him. He flashed me a big white toothed smile and said he hoped I wasn't thinking of quitting the club. He said he was friends with the manager and they had my address and shit, and it would be really unfortunate if I decided to quit. Then he laid one large basketball player sized hand on my shoulder and said that he would see me at the same time the next day.

Well, that's how it started. It got worse each time I went to the club. Barack and the other niggers got me to get towels for them, had me scrub their backs in the shower, even made me pick their dirty stinking jock straps up off the floor. They sent their filthy jocks and socks home with me to wash for them.

Now let me state here once and for all, that I am in no way at all gay. I don't think I ever even had a gay thought. So all of this really repulsed me. They would brush up against me so their big fat black dicks rubbed my body. They would make constant jokes about me being a faggot.

So I had it out with Barack. I told him I was a single parent with a thirteen year old daughter and in no way gay, and I wanted to quit the club. That mention of my daughter was the biggest mistake of my life. Barack demanded to see a photo of her. Her name is Crissy. After that, all they talked about was "Crissy the Cunt" in the locker room.

"Some fourteen year old school boy probably shoving his dick in her right now while you is at da club." They would say things like that. Barack would ask, "Do you suppose she had ever sucked black dick?" I told them she was totally innocent, and they should keep their foul mouths to themselves. They beat the shit out of me.

I didn't go to the club for a week. All the windows were broken on my car, and my newspaper was stolen, and somebody pissed all over our door. I received a package at work, and when I opened it, there was a pile of shit in a box. I was going nuts with anguish. I thought of going to the police, but I knew I would face even worse if I did. So I went back to the club. That was two months ago. A lot had happened in those two months.

Now I sat waiting for Barack to speak with me. He walked up, stark naked. The first thing I saw were his huge brown feet next to me. I looked up at his long muscular legs. How could I miss the seven inch flaccid dick, thick as a flashlight and the ball sack that looked like it had oranges in it. It was fucking obscene. His stomach was hard and tight. His ass was one of those round tight nigger bubble butts. His chest well defined with large nipples. He had a killer smile, thick nigger lips, and dark flashing eyes that often looked drugged. He had only recently gotten out of reform school for molesting a girl on the playground.

"So, my man, how's that little dick of yours hangin'?"

I spread my legs wider so he could see my pathetic shriveled white prick and small ball sack. If I didn't keep myself on display for them at all times, they would have a wet towel snapping session where my scrotum was the target. It hurt like hell and was totally humiliating.

"So, bro, is everything set up for tomorrow?" He stood close to me...so close that his huge flaccid hunk of fuck meat brushed my shoulder. His dick was so huge, it was just fucking obscene, and that was in its flaccid state. He had not showered yet, and his body reeked of the nigger stink of his workout.

"Please. Please don't do this. I know I agreed, but that was after you had beaten me almost senseless. Please, isn't there some other way?"

He lifted one leg and put his foot on the bench next to me. His gigantic balls swung back and forth in their fleshy sack.

"Dere is no other fucking way, man. You don't wanna even think of what we gonna do to you next time you disobeys us. Dere is no other way. Now it so happens dat I needs me a new girlfriend, and your pretty little daughter fills da bill."

I felt my stomach turn over. I tried to relax, to breath deeply, but I felt like I was choking. This teenage nigger thug was talking about my daughter. My little Crissy. My thirteen year old angel. He had announced to me that he wanted her to become his girlfriend! Jesus Christ!

At first I had bluntly refused, letting my anger and disgust show. All the niggers in the club gathered around me, about fifteen of them, and Barack announced that I was racially prejudiced and didn't want him dating his white daughter. They started to slap and punch me.

"It's not that. Honest to God, I swear, it's not that you are black. It's that she is only thirteen. She's my innocent baby!"

Barack roared with laughter. "Any bitch of thirteen is totally ready for dick! She probably sucking da boys at school every day anyway by now." He looked at the photo of her which he had taken from me. "Yeah, she got real cocksucker lips, she shore do!"

"Oh God no, she's just a baby." I was crying in front of all of them.

"No, daddy, you gots it wrong. She is a babe...not a baby. Dat pretty little pussy is ready for some nigger popping!" Half the niggers surrounding me were getting hard ons, and I don't there there was one under eight and a half inches.

For weeks I had argued, begged, pleaded, tried to bargain with Barack, but he only wanted one thing. My daughter's virgin pussy. Once I stood up to them and told them I would go to the police. They had dragged me naked and screaming into the health club bathroom and forced me to eat turds out of the toilet bowl. I was sick for two days. The next time I went to the club, Barack had made me suck his dick. That was the first time I saw it erect. Over twelve inches of throbbing leaking nigger cock. I had a panic attack and literally tried to run out of the club. They held me down on a bench and Barack fed me his black fuck meat. His balls almost suffocated me. His dick choked me. He even made me suck his ass. What could I do? I agreed to let them have my daughter. I know, I am an awful man. A sinner. It is unforgivable, but I am scared out of my wits.

"So, tomorrow, I comes over to yo house dressed up real good. You introduce me to yo bitch daughter. Now when I sees her, dis is how I wants her dressed. A very tight tee shirt dat says printed on it, "I Love Nigga Dick!" She will wear no bra under it so I can see the tips of her budding little titties through the material. Den she is to wear her nice pleated cheer leader skirt like in da photo, only I don want her to wear no panties under it. From now on, yo daughter is forbidden to ever wear any panties. We want dat fresh young cunt and ass ready and available at all times. I want you to have some really top drawer booze at yo house ready for me. I am not sure what I will want, so you better have enough to satisfy me, whatever my taste might be. Who da fuck knows, I may want a cosmo, or maybe some of dat Louis XIII Brandy dat costs three hundred dollars. You better have it all. After I has a drink, you pretty little bitch and I gonna sit on da couch and get acquainted. Dat means you as da daddy get to watch me finger her cunt and play wit her titties. You gets to see her meet my big fat old dick and even lick and suck it a little. I always insists on sex on da first date, cause how else you know how a bitch perform, right? Shit, I insist on sex on every date. I mean dat is da only reason for da fucking date..to plow some pussy! Right? Otherwise I'd rather hang wit da home boys. Now she gonna be a little uptight and scared at firs...right? Specially when she see my dick and she know dat huge motherfucker is gonna plow her virgin twat! Oh yea, if she got any hair on her cunt yet, you make sure she shave it all off before tomorrow. I wanna see bald thirteen year old pussy."

While he said all of this to me at the health club, his dick got thicker and thicker and long strings of pre-fuck started to hang from the fat pisshole.

"Please don't hurt her...please." I was shaking in my naked agony.

"Hurt her? No why the fuck would I hurt my new girlfriend? I gonna love her. I gonna show her da pleasures of lovemaking. Shore, it gonna hurt a little da first time I ram my twelve and a half inch motherfucking dick balls deep into her tight little teenage pussy. Shore it gonna hurt when I pounds her as hard as I can, and den pull out and shove it as hard as I can up her little asshole. Shore dat gonna hurt a little, but dat is jus' part of growin' up. A her daddy, you understand dat. Right? Better to hab some nice boy like me who wants her for his girlfriend fucking her, den every boy at school who don't give a shit about her.

"Now don't you worry, I gonna take her into the bedroom to fuck her cunt and ass. I think dat is private. I mean, you can watch da first time she suck my balls and lick my dick and such. But fucking is between a guy and his girlfriend. I wants you dere at the start...at the sucking part, cause she is gonna be scared like I say, and you can calm her. Tell her it is a natural part of life, and she just gotta learn to please a man. She, she shoulda learned dat couple of years ago already. She is a late bloomer.

Now I am gonna want to use her bedroom for da first fuck,cause I wants to fuck her little bitch body in her teenage bed, wit all her teenage shit around. It will be so hot. But den, I is moving into your master bedroom. You can sleep on da couch. I wants a nice big bed and luxury for future fucks. I gotta fuck at least three times a day, usually more. Now of course I still going to be bangin' other cunt, but I will fuck your daughter regularly cause she is my number one girlfriend. My special bitch. I ain't gonna introduce her to my bros until after I fuck her for a week or so. Den when she broken in, I gonna share her with all da boys from dis here health club. Dere about twenty of us here as you know, so she gonna be pretty busy sucking nigga dick and getting ass and cunt fucked. We gonna do mos' of it over at yo house. You have lots of food dere at all times fo my brothers when dey comes over to fuck your daughter. Since she be fucking most every day all day and night from now on, I suggest you apply to home school her. Dat way, she don't even need to think about school and she can concentrate on nigga cock all da time."

"Please, please use condoms...." I had tears running down my face.

Barack roared with laughter. "Condoms? Shit...no. We never use condoms. It ruins da fuck. Dat little bitch gonna be pregnant in a couple of weeks at mos'. You gonna be da grand daddy of a nigga chile! And who knows. She young. If she stay tight enough and cute enough, maybe we fuck her for three or four years, you know, pass her around, pimp her out. Shit, she still young enough. She could hab five or six nigga babies! We don' allow no abortions. She gonna breed. Now my brothers and daddy be comin' over lots to fuck her too, so you better have lots of keys to yo house made, or jus' leave the fucking place unlocked. She don't leave da house without permission. I would hate it for both of you if some black bro comes over for a good hard fuck, and she not dere! Now I know you worried about her. Don' be. After a few days of getting nigga dick, she gonna love it so much, dat all she gonna live for. I seen it in young white bitches lots of times. Someday she gonna thank you for all dis. I mean how many girls her age so lucky to get ten to fifteen black cocks a day? Long as her pussy and asshole hold up, she be happy. One thing, she gonna hab to be a really good cocksucker, cause One thig is dat when da boys in my hood meet up wit guys from other gangs...we got dis thing. We hab our girlfriends suck da cocks of all da members of the other gangs, as kind of a peace signal, you know, a sign dat we is kewl and everything is okay. So she gonna pretty much hab a dick in her mouth twenty-four seven for da next few months. She gonna be sucking on nigga dick even when she getting fucked by my bros. Dis house gonna be pretty packed full of black boys! Now, after a bitch has sucked fifteen to twenty dicks a day, she often get a real tired jaw and swollen lips and a sore tongue, so you gonna have to tell her no matter how tired she get, da last dick of da day she suck, gets jus' as good a suck as da first one in da morning. You gotta make sue she understand that. I can't have no bad reports from rival gangs dat my bitch can't suck!

Now we gots one more problem. Da little bitch gonna be so busy getting fucked and sucking dick, she ain't gonna hab no proper time to clean up da dicks after dey fuck her cunt and ass! You know it da bitch's job to clean a dick wit her mouth after a brother fuck her. I mean, you can't expect a brother to walk around wit pussy slime or ass juice on his dick. But she gonna be so busy, she ain't always gonna hab time to clean up, so you my friend is going to have to step up to da plate to help her. You gonna be the official dick cleaner. You gonna lick and suck da dicks clean after dey fuck yo bitch of a daughter. I want you naked on you hands and knees at all times around da house, ready to lick and suck dick clean. And you gonna do a fine job too, I just know it. You get all dat stink off da cock. Maybe you can entertain da brothers waiting next in line to fuck yo daughter too by lickig dere balls and assholes. I never thought of dat until just now. Hot damn, dat is a good idea, ain't it? So dey don't get bored while dey waitin. And den, to keep your daughter fresh and tight, after every three or four fucks, you gonna crawl in and suck the nigga cum right outta her pussy and asshole. Think how great dat is. You gonna get to suck some thirteen year old pussy and asshole! How lucky is dat? You gonna clean out her cunt real good with yo tongue so it is ready for da next nigga.

We gonna be da happiest family you ever seen! Now come on, white boy, suck my dick, can't you see it dripping all over da floor?"

I put my mouth over the head of the huge leaking hunk of fuckmeat, and resigned myself and my daughter to our new destiny.

A couple weeks ago, while taking my asian girlfriend shopping at the local mall, I had to take a piss. As I entered the john, Barack Obama -- the messiah himself -- came out of one of the booths. I stood at the urinal looking at him out of the corner of my eye as he washed his hands. He didn't once look at me. He was busy and in any case I was sure the secret service wouldn't even let me shake his hand.

As soon as he left I darted into the booth he'd vacated, hoping there might be a lingering smell of shit and even a seat still warm from his sturdy ass. I found not only the smell but the shit itself. He'd forgotten to flush. And what a treasure he had left behind. Three or four beautiful specimens floated in the bowl. It apparently had been a fairly dry, constipated shit, for all were fat, stiff, and ruggedly textured. The real prize was a great feast of turd -- a nine inch gastrointestinal triumph as thick as his cock -- or at least as I imagined it!

I knelt before the bowl, inhaling the rich brown fragrance and wondered if I should obey the impulse building up inside me. I'd always been a liberal democrat and had been on the Obama train since last year. Of course I'd had fantasies of meeting him, sucking his cock and balls, not to mention sucking his asshole clean, but I never imagined I would have the chance. Now, here I was, confronted with the most beautiful five-pound turd I'd ever feasted my eyes on, a sausage fit to star in any fantasy and one I knew to have been hatched from the asshole of Barack Obama, the chosen one.

Why not? I plucked it from the bowl, holding it with both hands to keep it from breaking. I lifted it to my nose. It smelled like rich, ripe limburger (horrid, but thrilling), yet had the consistency of cheddar. What is cheese anyway but milk turning to shit without the benefit of a digestive tract?

I gave it a lick and found that it tasted better then it smelled.

I hesitated no longer. I shoved the fucking thing as far into my mouth as I could get it and sucked on it like a big half nigger cock, beating my meat like a madman. I wanted to completely engulf it and bit off a large chunk, flooding my mouth with the intense, bittersweet flavor. To my delight I found that while the water in the bowl had chilled the outside of the turd, it was still warm inside. As I chewed I discovered that it was filled with hard little bits of something I soon identified as peanuts. He hadn't chewed them carefully and they'd passed through his body virtually unchanged. I ate it greedily, sending lump after peanutty lump sliding scratchily down my throat. My only regret was that Barack Obama wasn't there to see my loyalty and wash it down with his piss.

I soon reached a terrific climax. I caught my cum in the cupped palm of my hand and drank it down. Believe me, there is no more delightful combination of flavors than the hot sweetness of cum with the rich bitterness of shit. It's even better than listening to an Obama speech!

Afterwards I was sorry that I hadn't made it last longer. But then I realized that I still had a lot of fun in store for me. There was still a clutch of virile turds left in the bowl. I tenderly fished them out, rolled them into my handkerchief, and stashed them in my briefcase. In the week to come I found all kinds of ways to eat the shit without bolting it right down. Once eaten it's gone forever unless you want to filch it third hand out of your own asshole. Not an unreasonable recourse in moments of desperation or simple boredom.

I stored the turds in the refrigerator when I was not using them but within a week they were all gone. The last one I held in my mouth without chewing, letting it slowly dissolve. I had liquid shit trickling down my throat for nearly four hours. I must have had six orgasms in the process.

I often think of Barack Obama dropping solid gold out of his sweet, pink asshole every day, never knowing what joy it could, and at least once did, bring to a grateful democrat.

BUT, consider:

1. No known species of reindeer can fly. BUT there are 300,000 species of living organisms yet to be classified, and while most of these are insects and germs, this does not COMPLETELY rule out flying reindeer which only Santa has ever seen.

2. There are 2 billion children (persons under 18) in the world. BUT since Santa doesn't (appear) to handle the Muslim, Hindu, Nigger, Jewish and Buddhist children, that reduces the workload to 15% of the total - 378 million according to the Population Reference Bureau. At an average (census rate of 3.5 children per household, that's 91.8 million homes. One presumes there's at least one good child in each.

3. Santa has 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, and assuming he travels east to west (which seems logical). This works out to 822.6 visits per second. This is to say that for each Christian household with good children, Santa has 1/1000th of a second to park, hop out of his sleigh, jump down the chimneys, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left, get back up the chimney, get back into the sleigh and move on to the next house. Assuming that each of these 91.8 million stops are evenly distributed around the earth (which, of course we know to be false but for the purpose of our calculations we will accept), we are now talking about .78 miles per household, a total trip of 75.5 million miles, not counting stops to do what most of us must do at least once every 31 hours, plus feeding and etc. This means that Santa's sleigh is moving at 650 miles per second, 3000 times the speed of sound. For purposes of comparison, the fastest man-made vehicle on earth, the Ulysses space probe, moves at a poky 27.4 miles per second - a conventional reindeer can run, tops, 15 miles per hour.

4. The payload on the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium-sized Lego set (2 pounds), the sleigh is carrying 321,300 tons, not counting Santa, who is invariably described as overweight. On land, conventional reindeer can pull no more than 300 pounds. Even granting that "flying reindeer" (refer to point #1) could pull TEN TIMES the normal load, we cannot do the job with eight, or even nine. We need 214,200 reindeer. This increases the payload - not even counting the weight of the sleigh - 353,430 tons. Again, for comparison - this is four times the weight of Queen Elizabeth.

5. 353,000 tons traveling at 650 miles per second creates enormous air resistance - this will heat the reindeer up in the same fashion as spacecrafts re-entering the earth's atmosphere. The lead pair of reindeer will absorb 14.3 QUINTILLION joules of energy per SECOND, EACH! In short, they will burst into flames almost instantaneously, exposing the reindeer behind them, and create a deafening sonic boom in their wake. The entire reindeer team will be vaporized within 4.26 thousandths of a second. Santa, meanwhile, will be subjected to centrifugal* forces 17,500.06 times greater than gravity. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of his sleigh by 4,315,015 pounds of force.

In conclusion - If Santa ever DID deliver presents on Christmas Eve, he's dead by now. And he'd be a faggot.

======================
*Please note that centrifugal is a made-up non existent word. The real word should be centripetal. Centrifugal is a made up force that physics people HATE! So please, everyone use the world centripetal, not centrifugal. Thanks!

You might start with the very popular PIC. Although the architecture is a bit long in the tooth and is a poor target for C, there loads of example projects for it so it's easy to learn. There are also many high-level building blocks (Basic stamp etc) that can get you up and running quickly.

I would highly recommend the Arduino [arduino.cc] to beginners. It's a great target for C, and there's loads of example projects for it too. Seeed Studio [seeedstudio.com] has been a great resource for me, especially the store, and the forum. #arduino on Freenode is popular and very helpful too.

Bunny Guy (1345017) | about 4 years ago | (#31823124)

I heartily second this recomendation. This is the best guide I've found for lab electronics. I was a lab manager in a low temp fluid dynamics lab while a graduate student and I used to hand out my spare copy (yes, it's that good.) on a regular basis. Bunches of Phd Physics folk have been trained from this book.

Re:Forrest Mims (4, Informative)

serviscope_minor (664417) | about 4 years ago | (#31823266)

I can second almost everything that you say.

1. Forest M. Mimms III books are fantastic.

2. The PicStart1 kit is very good, with excellent Linux support. The PIC datasheets are very thorough and contain all the information you need. This makes using PICs really rather covenient.

3. The art of electronics is a truly excellent book. Amusingly, in the first edition, it points to the now venerable 741 op-amp as being obsolete. It is still going strong to this day.

4. Designing your own analogue circuits is hard. Designing your own RF circuits is very hard. It is about 70% theory and 65% black magic, along with about 10% blind luck. However you can start from existing designs. Build them to get practise then start modifying them.

5. Transmission line transformers are deeply strange.

Based on the OP's use of the term "GCSE", I assume that he is English. So: Find your local Maplin. They are very handy, since you can often pick up parts from the store, reducing the latency for project building if you forget to buy the right parts. Farnell and RS are handy places to mail-order from.

I also recommend getting a solderless breadboard, a DC power supply (a cheap wall-wart will do, as will 6V lantern batteries), a small tube of 741s and 555s, 100 resistor reels of: 100R, 1K, 10K, 100K and 1M resistors, a big bag of misc. caps, a reel of red and a reel of black single core wire, a multimeter, a bag of LEDs and a bag of small-signal transistors (eg 2N2222). That will do you for many of the things in (1) above.

Re:The Art of Electronics (4, Informative)

richardkelleher (1184251) | about 4 years ago | (#31824038)

I concur on The Art of Electronics. It contains most of the information I received in two+ years of Electrical Engineering classes. It starts out slow with the basics, this is a resistor, this is a capacitor, this is an inductor and the like. Scanning through my (now 21 year old) second edition, about the only area it doesn't cover that I got in school is power, but then power is not electronics.

If you are not interested in getting an engineering degree to do some DIY electronics, I'd suggest two places to start: 1. Make: magazine. Regular articles on electronic control circuits with some good information on how they work. (and many other great things I might add) 2. The Encyclopedia of Electronic Circuits, Rudolf F. Graf. (now called Volume 1, since they put out 6 more over the years) It has almost 100 simple to complex circuits with descriptions of what they do, but not much about how. To get the how, get The Art of Electronics and plan on reading a lot of the first 100 pages and then using it for a reference each time you try to decipher what some circuit is doing.

timlyg (266415) | about 4 years ago | (#31824066)

I checked, the Art of Electronics seems to also have a 620page "Student Manual" accompaniment, so I wonder which one you're referring? or both?

Start with DIY audio electronics (1)

searleb (168974) | about 4 years ago | (#31822992)

I would start with DIY audio electronics, since it's easy to test, usually not dangerous, and you get a useful product in the end. The CMoy amplifier is popular and has several good tutorials written about building them from RadioShack parts for about $25. The best is from TangentSoft [tangentsoft.net]. The CMoy has a simple circuit that should be pretty obvious to anyone with some classwork in electrical engineering. You can build the amp without that knowledge, too. If you enjoy it then there's a huge range of other more advanced kits and schematics to build from.

Re:Start with DIY audio electronics (2, Informative)

searleb (168974) | about 4 years ago | (#31823038)

I should also point out Tangent's tutorials [tangentsoft.net], which are fantastic introductions into wiring and soldering even if you're not interested in audio work.

Learn not to grab hot soldering iron by the barrel or tip.

Handle is much safer.

Metalesson 1: it doesn't matter if you think you need to keep your eyes on that twitchy almost-mechanically-sound connection in order to keep it from springing apart before you can solder it. You still need to pick your head up and guide your hands to the soldering iron, because grasping blindly WILL HURT.

This is not a joke. It is insightful advise and it doesn't matter how many times you are told before you start, you will still learn this lesson the hard way.

There is a reason soldering iron handles are bright yellow. It will still not stop you from picking it up by the hot bit at least once...

Re:Very important first step (1)

blair1q (305137) | about 4 years ago | (#31823430)

There's a reason pros use a soldering-iron stand that encloses the business end and leaves the handle in the most accessible position.

Laying your iron down on the table or a prop is lazy and sloppy.

Re:Very important first step (2, Informative)

ari_j (90255) | about 4 years ago | (#31823558)

For me, it was more cheap than lazy or sloppy. But I second most of the advice and offer the following:

Great soldering station with adjustable temperature: SS-1 for $40 [powweb.com]. Get this one or something like it. It's worth every penny.

Now, story time with a good moral. I was, two years ago, working on something with a super-cheap soldering iron that came with a computer toolkit with various screwdrivers and such, all of which are great other than the soldering iron. My grip on it slipped and my instinct from years of having pens and pencils slip in my hand was to pinch harder. Unfortunately, the lack of a safety guard on the iron meant that I pinched down very hard with my thumb and first two fingers on the hot barrel of the iron. The blisters went away after a few weeks but the pain lasted longer.

tftp (111690) | about 4 years ago | (#31823928)

There is a reason soldering iron handles are bright yellow.

I haven't seen a professional soldering iron with a yellow handle. Usually they are black [digikey.com] or sometimes cyan [digikey.com] as it is a trademark Weller color. Hakko [hakkousa.com] was traditionally black but now has blue irons too.

All these irons are pretty safe - in part because they come with enclosed stands, and in part because the handle's shape allows you to feel the position of your grip without looking. After a few years of practice burns of that type just don't happen.

The most popular type of a light burn among novices is produced by holding the part with fingers and soldering it.

Lesson 2: Don't let out the magic smoke.

While the general population may be unaware, electronics gurus know that all components rely on a small amount of magic smoke. Manufacturers want you to think that some sort of fancy semiconductor physics is responsible for the operation of their device. This is a lie.

If the smoke escapes, the device will no longer work. It is vital to the operation of the chip; do not let it out.

No other explanation is accepted by the govt anymore.

Up until a few years ago, if you wanted to play with electronics and build you own circuitry, you were free to do so. Hobbiests and ham radio enthusiasts commonly built stuff from parts from Radio Shack, Newark, Digikey, etc, but now the authorities are starting to watch such people very closely.

Do what I did (2, Insightful)

slimjim8094 (941042) | about 4 years ago | (#31823226)

I come from a programming background, and I wanted to get into electronics. So I bought an Arduino, a breadboard, and some LEDs. Write some C code, compile it and throw it on there, and blinkenlights galore.

But wait! It can also read analog values. Hook up a potentiometer and a LED, and dim it based on the pot's position. Or grab a 7-segment display and map the pot to the display's 0-9.

All of these use the microcontroller, and since I already knew how to program I knew how to make that part of the circuit do what I wanted. I had to learn how to safely connect the micro and the other components together - but I wasn't starting from nothing.

I'm working through RC circuits now, which requires a strong working knowledge of resistors and capacitors and how they interact with the system. Wikipedia is your friend

Basically, take what you already know and use it as a wedge to push your way into something new. For me, the wedge was programming.

A word of caution - You should know enough about electricity to avoid killing yourself before you even start. Internalize the difference between voltage and amperage, for one. But if all you're working with is the small side of a 9v transformer, you should be OK.

Breadboards! (1)

I recommend starting with one of the many breadboard kits that are around. A lot of times they're geared toward kids, but usually that doesn't matter too much. Once you have a chance to read their notes about how things work and get to try it out for yourself, you can start digging into more technical adult-oriented manuals and websites and if you pick well, you'll even have something to use to try your own experiments based on what you find elsewhere. The key is the ability to (mostly safely) experiment and learn what does what and how in a truly hands-on fashion. I like the added flexibility of the spring connectors (Maxitronix Electronic Lab) vs something more structured like the Snap Circuits, but it just depends on your needs, interests and whether there is a child who might be inheriting the kit when you're done.

I started with them and I'm still alive, and no permanent scars! There is reason for this though, and that is, tubes are very forgiving to mistakes. You can do retarded crap, watch the plates go red hot, shut it down, fix the circut, and it will come up and work again. I've had circuts thermal runway so hard they cook the cathode resistors and blow the coupling capacitors to shreds, replace the caps and resistors, fix the dead short at the plate, and have the tubes still operate perfectly. So you never damage any of the expensive parts, none of which are all that expensive.

Electronics or electromagnetism/applied physics? (0)

Anonymous Coward | about 4 years ago | (#31823724)

I think that you can divide electronic work in two major worlds: digital electronics and analog electronics. They both work together in most modern applications, but most people are more interested in working with either analog or digital.

You seem to be interested more in the analog and electromagnetism/applied physics. That means that you will be sitting around at a workbench analyzing and debugging analog circuits with an oscilloscope. You will also build a lot of prototypes and stuff with your hands. It can be a lot of fun.

If you go the digital path you will be sitting in front of a computer, coding embedded C, VHDL or Verilog and you will be analyzing the actual circuit with a logic analyzer rather than with an oscilloscope. That can also be a lot of fun.

It all depends on what you find fun. It would be difficult and probably fruitless and boring to get into both these fields at the same time as a newbie hobbyist.

By the way, oscilloscopes and logic analyzers are equally expensive. Prices start at about $150-$200 and you need to pay $300-$400 for a good hobbyist scope or logic analyzer.

Attila the Bun (952109) | about 4 years ago | (#31824044)

For the absolute beginner (which is about the level of GCSE physics), I recommend the books I started with. Look for Tom Duncan's "Adventures with Electronics". As well as circuit diagrams there are clear illustrations so that you can start building working circuits right away. The workings of each project is clearly explained, and followed by suggestions for expanding or altering the circuit to do something different. It's very rewarding: you don't need to understand the circuit before you start, but you certainly will after experimenting with it.

After the first book, there's "Adventures with Micro Electronics" and "Adventures with Digital Electronics" which introduce ICs and binary logic. Once you've got through these three books, you'll be sufficiently well grounded to pick up standard electronics texts to progress further.

Each book comes with a list of components which you can easily order from Maplin or RadioSpares. It's cheaper than buying a ready made kit, and the components are better quality than many of the kits (which will save you many frustrated hours). Any anyway you'll soon be buying more components to make larger circuits and your own ideas.

- Become a Ham. Study and take the tests. Basics required for Technician and General, Extra will require you to crack the books. Practice tests are available free on-line, but best is hamtestonline.com, which will teach you the subject matter, as well as the test. If you're not from the US, you will have a different test and potentially different rules, so YMMV.

If you want to get started get one of those 75 in one kits using spring connectors. The better ones run under 100$ and they have all that boring theory in somewhat in less boring action. If you really want to have fun, and just follow receipes, get one of the microcontroller based kits. The easiest (and not very powerful) is the stamp. Don't by a stamp kit, just a book and a simple stamp chip, you can make a stamp burner from your serial port.

Have fun. Soldering comes next. If you can't smile at a really big blister, don't get into electronics. If you like doing the cheap experiments, start buying more complex ones - most have the theory included. Then start buying books and equipment (not the least of which is an oscilliscope and signal generator - expensive and required), Better off determining if you really want to do this.

Eor.

KipKay has a lot of tutorials for projects on youtube. The Arduino project is a great way to get a lot of more complicated electronics projects started quickly. Again, google, youtube. Both of these things are more about application and less about theory, but they can be more fun that way.
