Note that his unit has still never been for sale, now 4 and half years later. Anyway, I decided that if it could be done then I could do it too.
After a couple of days working with Brett Thruber's car, I had something working. I published the schematics from day one so that no one would ever have to pay. I watermarked my name on it because I know how dishonest this industry generally is. I'm still amazed that these products were able to be successfully sold considering the very few dollars it takes to get the relays and build it yourself from the schematic. Every unit I have ever seen for sale copies my original schematic. It was far from perfect but better than nothing.
Then later, Sep 2014, I figured out the calibration which made it possible to use the L/R clutch instead of the direct. I initially tested that on a TVS car and when I was able to put it on the wood with no 2 step and the car didn't budge, I knew I had a winner. By this point some imitators had already started selling relays/wiring that were a copy of the earlier circuit. So while I still released the schematic immediately, I did not reveal the calibration needed to anyone except those who helped with information which made this newer circuit viable. This thread was the first time I revealed any of that publicly. I figure enough time has now passed. Seven second passes with sixties in the teens have been made with it, so I think it is working out pretty well.
