Re: dinky microstepping driver ?

Hi,

I have been following this thread for a while. It seemed interesting
so I drew up a schematic for a linear amplifier microstepping drive
power section. It would be good for up to 2-3A and from 12 to 50VDC.
A PIC or Basic Stamp wizard would have to come up with the drive
signals.

I have no interest in manufacturing it. If anyone wants to build it,
I can formalize the circuit in a .pdf format from my hand drawn notes.
