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.

The IGBT driver boards will be available shortly and are being manufacture as we speak. Powerex complete technical design and PCB graphics thanks to Paul's dedication.
These will be capable to interface with the 3 phase AC drive and /or the SR controller that Paul & Sabrina will offer.
Price will be as always, very affordable plus shipping.
I might offer a parts kit to go along with the PCBs as a total package, depending on budget.
Now, we are also taking commitment orders in a "
Group BUY" for the
VLA500-01 driver integrators that will be mounted on the aforementioned boards.
