Mariss,
Thanks for posting the Dyno circuit. Funny I didn't notice it, and I
looked at the files just the other day!
I take it you have a table of D/A values to current or oz-in? Is P2
then adjusted to get the 1v / 100 oz-in ratio? +12 and 0v to LM358 OK?
or do I need a bipolar supply? I have a mini-Minertia motor 21v, 4.8a
that I thought I try first. Only about 61 oz-in.
I bought a ratchet-type torque guage at one time, thinking I could use
it to determine the torque of a stepper motor. Ought to be good for
something!
