I might have done that already...can't remember.Quote:

Thanks guys! I just hooked it up to the 5V line, then the 3.3V. If anything, that told me I might want it running on LESS than 3.3V...of course, I then risk it not running at all. Still, I think I'll experiment with a resistor or two on the 3.3V line and see what happens. I need to keep in mind that with the shaft spinning by itself, it's probably a little faster than it'll spin when it has to drive 2 conveyors even though there won't be tons of resistance from them.
Do you have any hefty potentiometers? If so you can hook one up with any of the lines and give it a range from 0-maxV. Just make sure you hook it up as a pot, not as a variable resistor...or you'll blow up the pot...not that I'd know from personal experience or anything, of course not.. :whistler:
LOL - I'm sure it's exactly the same way that I'm aware, though of *course* not through personal experience, that hooking up 24 LEDs in parallel on a 12V line is not the same as hooking the same LEDs up in series on the same line, and thus is a good way to blow them to pieces.Quote:

Were there none in your box-o-stuff from Electronics Goldmine? I got two...though, idk which box they were in, come to think of it...
Nope. At least, nothing with a knob installed on it. There's a whole bunch of things that might be though, but sans knobs:
I have quite a few of these little jobbies, and up til now I hadn't a clue what they are. I Googled potentiometer pics and these are the only things I have that even come close to resembling them.
Yup, those are little trim pots. They probably wouldn't be able to handle the current levels you'll need, but you could always try and find a datasheet for one of them and see what its specs are.
