Dishwasher-Size, 25kW Fuel Cell In Development

FridgeFreezer Only 80% efficient? Where's the other 20% going? (379 comments)

I'm fairly sure gasoline engines manage 80% efficiency if you count heat output as useful.

Does the remaining 20% come out as noise? Light? Radiation?

I Wonder how much energy and exotic raw materials go into making this marvel of clean power?

I also wonder how efficient my gas-cooker is at converting gas into heat, as it doesn't seem to make any appreciable amount of anything else other than heat.

Ask Slashdot: Why Buy a Raspberry Pi When I Have a Perfectly Good Cellphone?

FridgeFreezer Re:Arduino Uno (273 comments)

Have you *priced* Arduinos and their accessories? If you're comparing one against *any* cellphone from the Nokia 5110 upwards the processing power is lower, the IO is limited (no buttons, display, or wireless connectivity for starters) and you can fish the cellphones out of the trash or off eBay for almost nothing, probably with full-colour LCD, bluetooth, camera, maybe even GPS. The bigger problem is breaking into the phone & developing software on it.

In fact the Raspberry Pi is cheaper than a lot of Arduinos.

Explosive Detecting Devices Face Off With Bomb Dogs

FridgeFreezer Re:In other words (115 comments)

Having read the link, that does not really prove that dogs are useless, just that they can give false positives if the handlers lead them into it. But no-one gets prosecuted because the dog thinks they might have a bomb unless it turns out they really do have a bomb. False positives are not a big problem if the alternative is either much more thorough/time-consuming/intrusive investigation or random selection.

US Military Tested the Effects of a Nuclear Holocaust On Beer

FridgeFreezer Re:Waste of money (215 comments)

Exactly, go back and read the stuff about the nuclear tests, they had everything they could find lined up around every blast - from live animals strapped to the decks of target ships to food, drink, etc., plus of course all the scientists and soldiers stationed about the place to observe & report. As someone above said, the cost of setting off the nuke is the big thing, so you may as well stack as much stuff around the place to gather data on.

UK License Plate Cameras Have "Gaps In Coverage"

FridgeFreezer Re:So, let's have a positive experience: (283 comments)

Cameras can also *see* cars, fake plates or not. If the ANPR hadn't flagged it right off, there's a fair chance the CCTV guys would have spotted it - and they could just as easily then stick the fake reg into the computer.

There's also a difference between car theives who sneak off with your stuff and car theives who are willing to risk an assault / ABH/GBH charge and the associated police response / prison sentence.

But you're right, we should go back to the police having a truncheon and a whistle and maybe a horse...

I think it's funny that google, amazon, and your bank/credit card probably know waaaay more about you than the authorities do, yet things like this get shit on in the name of freedom. If I get mugged, or burgled, or whatever, I want it to be on as many cameras as possible. CCTV is a massively EFFICIENT and EFFECTIVE way to catch criminals and make the Police and justice system's job easier and safer. With power comes responsibility, and we should be watching the watchers very closely, but not cutting off our noses to spite our face.

UK License Plate Cameras Have "Gaps In Coverage"

FridgeFreezer So, let's have a positive experience: (283 comments)

A friend of mine heard his car being driven off his driveway at night, called the police who typed his reg into the computer. Within a few minutes it had been ANPR'd leaving town, one camera later they knew fairly sure which way he was headed (motorway out of county), maybe half an hour later a police car rolls up behind him at a motorway services and cuffs both occupants, car returned to owner.

The issue is not the technology, the issue is how it's used and by whom. This is an excellent system for reducing vehicle crime - theft, unisured drivers, unsafe vehicles on the road, etc. that cost us all a shitload of money in taxes, insurance premiums, death. They can do this as much as they like, I'm cool with that, but I want to know that that's ALL they're doing with it, and that they're not selling my data etc. etc.

People need to stop getting all antsy about the technology and concentrate their attention / concerns / questions on HOW it's used.

FAA To Reevaluate Inflight Electronic Device Use

FridgeFreezer Re:Oh please no (336 comments)

Pretty much anything electronic generates some noise, as pretty much everything has some sort of oscillator in it, because these days everything has some sort of microprocessor in it. Even if your device is off, its battery might have its own processor ticking away. Any device which remembers the correct time through power-down must have *some* oscillator running ALL THE TIME. Your phone probably has 3-4 radios in it (1/2/3/4G, WiFi, Bluetooth, NFC, FM). There's so much complexity hidden in modern stuff (not just obvious electronic devices like phones/laptops) that people forget it's even there. And sometimes made very poorly.

Logitech Releases Washable Keyboard

FridgeFreezer ALL ELECTRONICS is washable, ffs. (205 comments)

I realise there's a low quota of hardware nerds on here, but most electronics gets washed on the production line to remove flux and contaminants.

The biggie with *any* electronics is to not use anything that causes damage or corrosion, and to have the device powered off until it's absolutely dry (if using water) to prevent shorts or electrolytic corrosion.

The best thing is isopropyl alcohol, aside from being a bit of a hazard to some paint/stickers etc. it's about the top thing for cleaning electronics.

Asking Slashdot: Converting an SUV Into an Hybrid Diesel-Electric?

FridgeFreezer Re:Decent idea, contrary to some of the comments (543 comments)

True most static engines are not designed with lightness in mind, I was kinda ignoring that aspect and focusing more on the state of tune of the engine. Whatever you chose, you may gain a fair bit by getting a custom profile of camshat made and looking at the other stuff you can do like inlet/exhaust port tuning. When you know you want the engine to only run at one speed, you can tune stuff for big gains without having to worry that it would be undriveable in a normal car.

Another point about static engines is they are designed with far longer running hours than most motorbike engines - chances are someone will have thrown it at a tree before it's done 50k whereas a genset may have to run for some hours a day, every day for decades.

There are crossovers - the International HS 2.8 4cyl turbodiesel is a re-jig of the Land Rover 300TDi engine, which was a re-jig of the 200TDi, all excellent engines and well proven, although not light (well, not by european standards... cough). Crops up in some Ford trucks around the world, as well as updated army Land Rovers, also available in "generator" spec - could be worth looking at what the differences are.

What if vinyl had DRM?

FridgeFreezer FridgeFreezer writes  |  more than 5 years ago

FridgeFreezer writes "As has been demonstrated, DRM is particularly hopeless if the company running the service shuts down its servers or goes bust.

This set me thinking — with the record industry being a fairly fickle place, which classic masterpieces and seminal works would be lost today if their originating label had somehow managed to put DRM on 12" vinyl?"

An Open-Source land speed record?

FridgeFreezer FridgeFreezer writes  |  more than 5 years ago

FridgeFreezer writes "Gary Hart recently set a world record of 240.984mph at Bonneville SpeedWeek 2008. The point of interest is that his car (a '53 Studebaker) is equipped with a completely open-source engine management system called MegaSquirt, a fuel injection and ignition ECU that users can buy in kit form for under $200 and solder together themselves. The circuit schematics, firmware, and tuning software are all open-source, and contributed to by users from all over the world through project forums.

Given that most race teams will spend many thousands of dollars on professional engine management, this is a remarkable feat for a piece of open-source hardware.

Additionally, the same setup can be used to add modern, efficient fuel injection to elderly carburettor-fed vehicles, perhaps the automotive version of overclocking?"
