Re: [ATM] stepper-motor-controller??

Hi John,

I've used this circuit from H&R to drive a stepper on an equatorial
platform for my 13" DOB.  I used a different stepper motor than the one
supplied, one with a 200-1 ratio gear box, also from H&R.  The circuit
has performed more than adequately and is not a bad deal.  I recommend
it.
