dcb, he was talking about the cheapo chinese breadboards, I think. In reality, I think the cost of developing with this chip or that is not relevant, because i think that we should be developing a "standard" interconnect between controller and drive boards. This way, any processor or architecture (fpga, maybe?) can be put on the control board and plugged into any power board. After Paul is done, an AC or BLDC open-source controller could be made and the same control board plugged into it. With this done, anybody's simple and cheap or fancy and expensive control board could be attached to anybody's simple and cheap or fancy and expensive power board. Sure wish i could drop a cheap imported honda motor into my mazda when the engine poops out, or move my motor into a new vehicle when the car rusts through.
