I did google for it -- without the right search terms, they're a little hard to find. I found one in an old robotics book, though...
Regardless, that's what I was aiming for. Something which, despite buying parts at Radio Shack, could be built for $5 or so. Even on a breadboard, if desired.
It doesn't have to work beautifully -- just work as a proof of concept model for a single axis, to prove to people that they can actually do this CNC thing, without having to pay $100+ for Geckos, before anything even moves.
I'm not an electronics guy. If I can build one of these (and ever find enough continuous spare time to focus) then anyone can.
