Some improvements

I raised the voltage that I run the motors to 12 volts. They run hotter but I don't think they are too hot. That let me speed it up about three times what it was. I tried some things to explore the limits and characteristics of the system.

Then I went back to some old favorites and updated them to work with the LEDs and switch that I added.

They look a lot better with the 12 volt steps.
I am working on some of my other old favorites.
