RE: [APML] Stepper motor speed controller?

["Gene Horr" <genehorr@houston.rr.com>]

Well, no, but sort of.  This is a controller for the
Gecko.  You can program them to do what you want but
this sounds like overkill for your project.  

You can take a Gecko and feed it a clock signal from
a relatively simple circuit.  

A really cheap solution is one of those little hobby
kits.  You have a variable pot that controls the
speed.   Unfortunately I can't remember any of the
kit names but a local electronic hobby supply shop
should have one.  They run in the $20-30 range IIRC.
