Dave, I wonder (also) about a control that can pulse (PWM) in various ratios of neg/pos square waves as high grade welders do now. I have a Miller Synchrowave...

I recently bought a lot of five gear motors on Ebay. They aren't the ideal specs, but they should work. I liked them because they are fairly small. They are...
I have been looking at these motors as well. Trying to make a decision. Was wondering what the 162 rpm effect on the operation would be. Ben recommends in...
I think the motors will work, but not sure how well. I am afraid that it will be easy to get into an oscillation situation. The motor retracts in a short then...
