I'm starting out with 3 motors sitting in front of me, a regular DC (from an ink-jet printer feeder), a Unipolar stepper(from an old IBM typewriter) and a bipolar stepper (from the aforementioned printer). I'm actually guessing about the bipolar stepper but it has 4 leads so that's my assumption.
All motors already have a cog pulley (or gear) pressed on the shaft. Hopefully getting a belt to match will not be impossible.
Surely someone can point me in a direction for good relatively inexpensive mechanical parts like cog pulleys, belts etc... that I could never make myself.
This will be my first venture into the mechanical world and it will have to be "build design" as opposed to "design build"
Of course I plan to use the Prop ProtoBoard USB that I received at the Unofficial Expo yesterday. I think the Unioplar stepper will be easier to drive than the bipolar (never tried to do anything with the bipolar yet) and unfortunately the plain old DC motor appears to have a helical type pulley and of course the belt is long gone.
