[Lab] [ORE_bits] stepper drivers

[Michael]

You could design your own driver, I will donate/supply the controller ic 
and passives ....

I have a bunch of these parts taking up space that I may never get 
around to using..
It would be great to see them put to a good cause... They are AMIS 30512...
I also have a variety of power stages: MC33932,  L293DD, L298P, ULN2803 
that could be used with a mcu to make a programmable stepper controller...

If someone is willing to design one for the purpose of donating it, I'm 
all in on supplying the parts ...
I'll even toss in an extra set of parts for whoever designs it, to make 
one for themselves...
Disclaimer: As long as the parts used are parts I have in stock, I have 
a good bit of kit on hand, mostly smd...
