GateCrusher over in general chat just reminded me of something. Boeing is using a kinetic switch developed by someone (can't remember who) and I just got this idea. I would like some opinion on making a wireless keyboard that relies on kinetic energy to send a signal rather than batteries. I suppose this would be achieved by making each individual key have some sort of kinetic generator and capacitor on it. The only issue I would see is if you needed to hold down a key like shit. Thoughts? (Before anyone says anything: Yes, I know I have to many projects)

That would probably also make bigger and way more expensive. Not to mention more stuff that could break.
I recently worked in the watch business and I took a glance into the technology utilized in Seiko's kinetic watches. It would take a lot of changing around (after all you're goin from watch to keyboard), but it wouldn't be that expensive to mass produce. Especially not with what's available for manufacturing. I'd estimate a keyboard price of around $150 which isn't much more than I payed for mine.. I have to replace my batteries every 2-3 months though. It gets annoying lol.

there is a watch that uses th emovemnt of ur arm/wrest that powers it self but it is still to big to put under a key.
The generator is barely 7mm.
OK, but wash it first

I suppose it would be feasable if you could keep the costs down. Maybe by only putting the generators under the most commonly used keys.
That's the problem and it again goes back to: What about shift, alt ect... The keys that need to be held down a bit longer. Edit: I'm brainstorming here.. This is the same way I came to the base-3 number system.. asked around and toyed with ideas untill BAM! Hit me like a ton of bricks.

Why would anyone want to use base 3 for anything?
Anyway--why do you see this as a problem? I've been using my current wireless keyboard for about a year or so now (maybe even longer?) and I cannot recall ever changing the batteries. There are Duracells in it now, which suggests that I might've done it once since I've had this keyboard. Hardly enough to warrant $150 for one that generates its own power on keypress.

The hell with kinetic energy, just make a nuclear energy keyboard. Never have to worry about changing batteries.
I guess the radiation might be something to be concerned about, but once you get past the cancer and testicles shrivelling up it's not all that bad.
If you did cold fusion you could do it with extremely low with radiation and probably distilled water.. Few drops would run it on a microscopic level for a few hundred years. But if you can do that you could run Vegas for a year on a cup of water and you'll be the richest man alive.
