Thanks. I'd been looking at gesture controller chips, but it wasn't clear to me how they worked, and I didn't realize there was a breakout board available. They're cheap enough, so I'll probably order one, and check it out.
Okay thanks. Giving this some more thought, I think my best bet is to find an old PS2 mouse and salvage the chip and optics from it. Because I'm going to need the optics no matter what.
How did you find the price? When I click on the link, I don't get any price info unless I submit a price request (which I don't want to do). I doubt that they'd be selling them for $0.50 each unless I order several thousand.
I'm looking for what is essentially a one dimensional version of an optical mouse sensor. I need to have a non contact sensor that can detect lateral movement of a target in one dimension only. I could use an optical mouse sensor, and use only one axis output, but all of the current mouse chips...
I'm trying to find a replacement for this rechargeable lithium battery that came out of a Bluetooth headphone adapter. It's a 3.6 V battery with wire leads.
Dimensions:
Length: 28mm
Width: 9mm
Thickness: 4mm
Can anyone point me to a part number, or generic type number?
The problem is that you can't avoid physics. What the turbine/generator takes in, in mechanical energy, must be delivered to the final load as electrical energy. Anything that's left over is converted to heat. Unless you get rid of the heat, you have problems. You have two options:
1. Don't...
Hi everyone. I've been away for quite a while, mainly because the barrage of pop-up ads drove me away. Is it my imagination, or have a lot of others also disappeared. I don't see anywhere near the activity on this forum that I used to. I'm not really surprised.
Doesn't appear that the site...
I can think of only two reasons why you would need to control generator speed:
1. Prevent it from running too fast and flying apart.
2. Vary the output power.
If it's the first reason, then the only solution will be mechanical or electro-mechanical.
If it's the second reason, then there are...
