Great news on the IGBT driver board. I'll just have to buy one of those and wait for the next version of the control board. I don't suppose he mentioned what the cost might be?

Oh, speaking of pinewood derby cars, not only should you mill out the back end and melt lead down in there, you should also take the metal rings/burrs off the nails they give you, then shove some pure graphite in there. Then the wheels will spin for 25 seconds if you just hold the nail and give it a nice spin holding it off the ground. If you're really a perfectionist you can shave out some of the inside of the wheel as well for more weight in the back.
