Here is a little circuit that helped the team out testing our prototypes and robot builds. I had been asking to purchase a high amp variable DC power supply $$$ to run motors while testing our prototypes without hooking up a crio, programming and all the electronics needed. Brian Silverman and his dad told me there is a easier way and drew up this circuit on a napkin and later made the box. What it does is generate a PWM signal that is variable with the use of a pot. We can safely control motor speed with a Jag or Victor without hooking up all the electronics.

I can't tell you how great a device this thing is. I saw so many shooter videos where people just touched bare wires to a battery to get their shooter motor runnning.
