Hand-Powered Hardware?

quiddity writes "Following the Goofy USB Devices post, one has to know what can be self-powered when the batteries all die. You can handcrank your Gameboy, recharge your cellphone or pda (even grandpa), wind up a webserver (with minions, a beowulf..), see in the dark, and project a movie. What else can we propel through the next blackout/apocalypse?" Some of these devices have have been on Slashdot before; what cool hand-powered tech hasn't been and should be?

BEND OVER ROVER (-1, Troll)

Anonymous Coward | more than 10 years ago | (#8493745)

Animal sex is not illegal in Sweden, and every year between 200 and 300 pets are injured because of sexual assaults.
The estimate was presented by Svenska Veterinarforbundet, the Swedish veterinary organization, and it is now trying to make the authorities and the public more aware of animals? suffering. The organization claim the problem has increased during the last couple of years, even if most people are unaware of it.
"We have seen an increase since 1999 when child pornography became illegal," said Johan Beck-Friis. "It appears, in other words, as there are some people who have replaced children with animals. In both circumstances, it is sex with defenceless individuals."
The injuries inflicted on animals after sexual assaults are of the same character of those children get. Beck-Friis said that the most common injuries are wounds on the sex organs and blisters.
The fact that animal sex is becoming an increasing problem can be indicated by the mere fact that there is an increasing selection of animal porn at video rentals and there an increasingly number of websites with animal pornography is surfacing.
No one knows for sure how many animals that are abused, but a British study from 2001 indicates that every 20th dog or cat that receives treatment at veterinaries, the injuries are not a result of a direct accident, but the animal has been inflicted the injury as a result of a sexual assault.

We are now at war. There are but two alternatives: Total victory, or total defeat.

There can be no such thing as a negotiated peace, or any other form of military stalemate that would result in the survival of Slashdot. That is the opinion of a group who know -- Trollkore, for 15 years 'THE PREMIER SLASHDOT TROLLS'

Trollkore speaking. TACOS's "New Order for the Internet" provides for the expansion of Slashdot until mindless drones occupy all of the Internet... not only for the present, but for all time. But to claim all of the Internet, TACO must eliminate its present population. Thus, for TACO and his followers, organized, systematic unemotional mass murder, depopulation and slashdotting have become the means of getting rid of captive peoples and dispelling forever any threat to TACO's "New Order".

So we Trollkore say to you... Troll for your freedom - after all; Better pot luck with Trollkore today, than humble pie under TACO tomorrow!

I remember reading about a device developed specifically to assist third-world countries with their crop planting and communications via a radio that is hand-cranked and provides a large amount of listening time per crank.

Apparently these countries suffer from a lack of information about weather patterns, which would greatly assist with the crop planting, and which is provided by the hand-cranked radio

An example of geeky inventing that actually has practial application, rare on slashdot :).

Re:I remember... (4, Interesting)

jejones (115979) | more than 10 years ago | (#8493953)

I've bought a couple of theose radios; one AM/FM, the other AM/FM/shortwave.

The generator starts to sound like it's grinding itself to metallic powder in fairly short order. I gave away one of them, so I don't know its fate now, but the AM/FM/shortwave one sits unused. It didn't take very long for whatever governs it so that the spring doesn't immediately unwind to break, so that if you wind it up, the knob turns at amazing speed, the mechanism sounds like you should do a bad imitation of Scotty and yell "She's gonna blow for sure, Captain!", and it unwinds itself in about one white-knuckled minute.

The radio circuitry is constrained by the power source and the need to not consume it quickly. No doubt ingle-conversion, poor image rejection. Analog dial that you can't tune with certainty, just like in the old days! The sound quality, though is very nice (which for SW means wide selectivity--ouch...).

I hasten to add that Freeplay has some far more sophisticated radio products these days, vide the Summit [freeplay.net] receiver.

It was developed by the Jhai Foundation with help from Lee Felsenstein. Lee Thorn founded Jhai - he is a Viet Nam vet who wanted (needed) to find a way to reconcile his experiences in the war with the people of Laos.

Here is a link [techempower.net] to an article about the bike-and-linux powered computer they developed. It is pretty cool.

Here is a link [slashdot.org] to a previous slashdot story on the machine. There were a lot of dumb comments previously on this story for some reason.

Here is a link [jhai.org] to a page on the Jhai Foundation's website about the concept. Last I heard, the project was hung up in Laotian red tape, waiting for some bureaucrats to give it the green light. I have no idea why a project like this would pose any threat to the government of such a country, however. Hopefully these problems have been resolved.

Interestingly, that hand cranked radio (I have one here) actually allows you toload a spring which in turn drives its small generator. This is way more economic then using a battery (less loss when storing the energy)

Only for 6 minutes at a time? (2, Interesting)

loyalsonofrutgers (736778) | more than 10 years ago | (#8493829)

The Cell Phone hand crank article wasn't too clear, but can you only wind for 6 minutes of call time at once? The way i see it, if 30 seconds of cranking gets you 6 minutes of call time, then why don't I just crank for 5 minutes and get a whole hour? The article, however, kind of implies that you gotta crank it everytime you want to make a short call. Which would suck.

I recently broke my cell phone charger (cheap POS from sony ericcson seperated, leaving the plug in the phone and the leads not). I'm too cheap to replace it, and the car charger is too inconvenient (I don't drive much). Something like this would be terribly convenient, except replacing my real charger would probably be cheaper.

Re:Only for 6 minutes at a time? (2, Interesting)

powerpuffgirls (758362) | more than 10 years ago | (#8493945)

It is probably because energy is stored in the spring (mechanical?), so unless you have a really big spring, you can only do so much (30 seconds).

Wrong: the average Jow Blow who doesn't smoke and exercise somewhat regularly puts out between 75W and 120W for 2 hours. Well trained folks can put out 200/300W, and extremely well trained people (thing Lance Armstrong rushing to the finish line) up to 1kW peak for a short time.

The Gossamer Albatros [rtpnet.org] for example, was powered by a 40Kg athlete woman who put out an average of 300/350W for more than 3 hours continuously, which explains why she was pretty knackered when she arrived.

How many slashdot editors does it take to handcrank the slashdot servers?

Four (1, Funny)

Anonymous Coward | more than 10 years ago | (#8493960)

One to hold the crank. Three to turn the server. And one to misspell something.

Doesn't that make five?

Considering how people flail and pound on buttons (5, Interesting)

squarooticus (5092) | more than 10 years ago | (#8493934)

when playing Gameboys and other such devices, isn't it possible just to harness all the extra energy expended beyond that which is required to tell the device, "Yes, move up, and then left, and then..."? Don't mod this up to funny: I'm serious. Think of all the energy that is wasted by just heating the plastic, when it could go into powering the device in the first place.

Well uh.. To some extent this is what modern cpus are doing, but in general, most of the power doesn't really go to the cpu in something like a gameboy (advance or not) Things like sound, display etc take up a fair share. Oh, and eh, the warming up of the device, well, this is an unwanted side effect, count on it that if it could be reduced in a feasable way, they'd do so.

If you can figure out a way to convert such a paltry amount of heat into useable electricity, tell me, and we'll both be billionaires.

Hand-cranked web server? (0, Redundant)

Oh, I really wanna see that. Can you imagine how much he'll have to crank his ass off when he gets slashdotted? On the other hand, we could build a great weight-loss / fitness regimen into something like this. You can KEEP your Herbalife.

If its really bad you'll need one of these... (0, Offtopic)
