Does anyone know of an alternative supplier for the nice Panasonic Sunceram solar cells? Alas, Solarbotics now just has the polycrystalline ones, which just...

Hi I was initially interested in the conventional 1381SE circuit. but then as an addition I wanted to add PD also as I have 2 PDs with me. I assembled the...
All, It's getting close to x-mas time again and I'm thinking about asking for a new soldering iron (station) and multimeter. I'm looking for recommendations....
Reese, Shameless self-plug here because we sell this stuff, but here are some things to look for: 1) For tools in general, but especially soldering irons and...
... For the soldering iron, you want temperature control rather than just power control. Some of the cheaper "adjustable" irons look to be little more than a...
You can not go wrong with a weller soldering station. I got this one as a gift last year and I love it. I use a different iron tho, but I can't remember the...

Is there any readily avaliable opamps like the 741, but with dual opamps and about 2.5 volt operation? I'm trying to find one which I can run off the...
Unlike batteries, which have a relatively constant discharge voltage, a capacitor voltage will drop linearly with time since opamps usually draw constant...

Sounds like a fun project. You might want to use an h-bridge that has a default 'stop' condition when receiving no signal. Then you could just send two...
