Gears aren't as cheap as they should be as Erik Rossen noted oh so long ago. So, I was trying to use tee-nuts as a crude gear that would be moved 1/4 turn by a rod perpindicular to the shaft of the motor. It works, and it's cheap, but I'm not sure if I'll incorporate it or not.
Here's a pic.
The the element perpindicular to the motor shaft is a bolt. It's attached to the motor shaft by clamping it to the shaft with a couple of nuts. There's yellow tape on the end 1) cus it wanted to be just a little bit longer and I didn't have a longer bolt and 2) the end needed to be smooth so the threads of the bolt didn't catch in the edges of the tee-nut.In other news I was looking for a good, mass manufactured piece of plastic that could be used for the mirror frame (adding stiffness) and as a replacement for the perforated angle iron. The cost of the metal pieces is a bear. Larger diameters (2"? 4"?) of PVC pipe that was ripped lengthwise might work well and be a better price point, but it adds some complexity to acquiring the material cus you can't just buy it ready to use. I'll investigate and report back but I'm trying to get a version built that's decent enough to post a parts list with costs and instructions on how to make it.
