Here is a much more readable version of the patent application on my motor speed regulator. Google Patents is great! No TIFF viewer is needed and you can download a PDF version of it.

Cool that someone did this, but if I'm not mistaken these types of tools are readily available for purchase.  So NOTHING NEW HERE.  Can't we find more interesting and unique gadgets to feature in this segment.  Maybe I'm just being a curmudgeon.

I have not seen a drill motor that is so easy to hold in the hand that has decent speed regulation and torque. I have a Dremel Moto-Tool that is great for big jobs, but it's awkward to use for delicate work. The Chinese mini-drill is dirt cheap and with my speed regulation technique, a piece of useless Chinese junk has been turned into an indespensible tool. I stand by its usefullness.

I own a cordless, three-speed electric floor sweeper that has my speed regulation system in it, so somebody else has found my invention useful. IMO, there is no cheaper way to regulate the speed of a small DC motor. I helped a guy in India tune the software program to run a larger motor for a CNC machine he was building. It was working for him, the last time I talked to him.
