| Hey y'all -- Here's a good one. I've recently bought a Zoom Q3 portable video/audio recorder, and as most of you know, the audio quality is outstanding, for what it is. We've been recording our practices, and trying to get some passable video footage to put up on Youtube. Funny thing is, it seem to be cursed when used at gigs. The three times we've had it at gigs, each time something has happened to cause total failure of the intended goal, but I digress.
During practices, we realized that once we've found the sweet spot in the room, the camera can be mounted to a tripod, and rotated, to capture each of the band members during the performance, surprisingly without much degradation of audio quality. Problem is, somebody has to rotate it. My not-so-brilliant solution was to rig up a gear motor to the tripod, to slowly rotate it at a couple of rpm's, thus capturing everyone, a few times throughout in the video.
I found a motor on ebay, which is rated at 3 rpm, 12 to 24 volts. The amperage was not listed. I have the motor, but I don't know what needs to happen to make it run. I took an 18v transformer I got with my Analogman mini chorus (great pedal), thinking voltage right in the middle, should work. It doesn't. My guess is that the amperage is off. It supplies 150 mA, but I have no way of knowing if this is enough. I'd like to hear any suggestions or educated guesses on this. Hopefully skod sees this, and explains it in a way I can understand...
