Grab a cheapie H-bridge and drive it from at least a 555 or better yet, a PWM from a Picomite  

LOL -- this is something I am retro fitting to an existing device in schools - rough and ready is best.

At presented the set up drives to motors far far too fast to use on a desktop - more like a school hall -- so this is almost like a "calibration" I am trying to hack back in.

I'll give it a go and see what happens.
