`Bionic' Arm Brings Back Sense of Touch

It is well and good until the arms short circuit and try to kill him...

...to robot pricking each finger and palm, one by one, as the patient says "ow!" and then wrapping the prosthetic arm in a black glove...
The next step is finding out that Darth Vader is your daddy.

These work using a peltier junction. For those not "in-the-know", peltier junctions are basically chunks of metal that push heat to one side when you run current through them one way, and the other side when you run current through them the other way. This provides a cold, and a hot side that can be varied very quickly from cold to hot, by changing the amount and direction of the current. They are very inefficient though, requiring a lot of current that is generated as excess heat overall. These are commonly used to cool processor cores down, pushing more heat into the heatsink, but keeping the core cooler than it would be with just a heatsink.

Nothing says "unprofessional job" like wrinkles in your duct tape.
This reminds me of the old joke about the voice-actuated artificial arm.
They finally attach one to an armless human patient and it goes like this.
The guy says, "Arm, scratch my nose". And the arm does it.
"Amazing!", says the guy.
"Arm, sign my name." The arm does it.
This continues for quite a while. Finally when the guy's alone.
He says, "Arm, take off my pants." The arm complies.
He looks at the arm, and then at his penis and says, "OK arm, jerk it off!"

So far it's only cost about $100,000, which is far cheaper than the $6,000,000 that was originally estimated. Maybe we'll get a little closer to that price once another arm is added, and some legs and a head and body...
I'll turn into a supernova and burn up everything. Well I'll turn into a black little hole and you'll turn into string.
Anybody want to take bets on how long it takes for a Linux dist. to be built for it?
I keep wondering if advances in prothetics will slow research into regrowing limbs. Once the replacement becomes better than the real thing, will people trade in their real arms for fake ones?
Masturbating without a sense of touch is way better though, it doesn't feel like you're doing it... Not that I'd know! :P

Rewired, amputee lifts arm with mind
More like one of those instants where your brain, while processing the signals you've just sent to your appendages, says to itself:
Fuck. This guy's an idiot.
I've done stupid things with electricty. Similar things. Not once, but twice, I've touched both metal ends of a Flourescent light tube while the light was on. Once while a box cutter was in my hand, touching the metal end of one of the lights. Not me showing off being an idiot, just having one of those beautiful moments where Darwin should have taken over. My hands got moving faster than my mind could slow them down.
This guy was probably up on a cherry picker. His weight shifted, a gust of wind came along, etc and as he started to fall his insticts yelled:
GRAB SOMETHING!
meanwhile his mind, not really paying attention sees what's happening and says:
Nono don't grab th.....nevermind.
Yeah, the guy probably screwed up somewhere down the line but Shit will invariably, consistently, and always, Happen.
There are some people that if they don't know, you can't tell 'em.
