I wonder if wireless mouse using the ball would last much longer on battery. I guess, it could. It still uses a led light internally, but I don't think it needs to be that strong.
- LeifCarrotson 8y agoA wireless mouse could last indefinitely, if it used magnetic resolvers instead of encoders (and siphoned off a bit of the voltage to recharge the battery. I expect you could also make a self-powered keyboard with a coil and magnet under the spacebar...
- jakobegger 8y agoThe problem is, if you use the rollers to harvest energy, they would have higher resistance to rotation, and thus would slip even easier...
- tinus_hn 8y agoThe keyboard has to remain connected when you’re not using it.
- LeifCarrotson 8y agoWhy?
- hnlmorg 8y agoI don't recall any of the mechanical mice I've taken apart having LEDs inside them. IIRC had 3 rollers/wheels which physically touched the ball and that was what "sensed" the motion. I'm talking 90s sort of era though, so it's possible more recent mechanical mice were designed differently.
- megous 8y agoRollers were connected to wheel with a plenty of holes, and there was a led + fotodiode that was used to detect the motion of the wheel. At least that's what I thought back then. (> 20 years, heh) I also remember just two rollers/wheels (X/Y). For example, this page: https://computer.howstuffworks.com/mouse2.htm https://computer.howstuffworks.com/mouse2.htm says something about "optical encoding disc".
- chrisseaton 8y agoMost basic 80s and 90s mice used LEDs to track the ball, via secondary wheels. They’re tiny and don’t look like lights so you probably overlooked them.
