Ive read where robotics folks are using a basic stamp and a HB-25 motor controller with the wiper motors and the smaller power seat motors in their robots. The stamp/motor controller uses pulse width modulation (PMW) to control the wipermotor RPM without losing torque and also gives it the precision movement like that of a r/c servo.

If this works as they say...can you imagine what can be done with this very strong little motor in props! ...a servo on steroids...

I couldn't resist, I ordered one from Parallax and it will be here tomarrow.

I'd be very interested in your evaluation of that controller randyaz. Please let us all know what you think after you get a chance to play with it. I'd certainly like to have servo-type control over a wiper motor!

Thanks for the link to that motor randyaz!

I too would like to hear/read your review once you've had a chance to test it.

Hooked everthing up and inital impression is that this is going to work great. It gives complete control over the motor speed, direction, and time. I currently have it sweeping back and forth through about 30 degrees. Its keeping the 30 degree sweep but is slightly creeping past the stop point on about every 5th sweep... I figure this can be corrected with some tweaking of the code.

So far Im very pleased with this and its possibilities. I wish I had got it earlier....
