Here are a few things I've been playing with:

1) K8055 card and homebrew relay card - relay card allows the K8055 outputs to operate 120VAC lights or other 120VAC devices. Connectors A & B are where the high voltage and the devices would be connected.



2) Prototype circuit that controls the speed and rotation direction of a small DC motor. Uses 1 K8055 PWM output for the speed reference, and 2 digital outputs for FWD/OFF/REV. Because the K8055's PWM carrier frequency is much higher than it needs to be for speed control (and it can not be changed) the low speed torque characteristics of my circuit are not real good. I think my next version will have its own adjustable carrier oscillator and modulator on board, and will be controlled by a K8055 analog output instead of using the K8055's PWM.



(Don't laugh too hard at my HUGE diodes! I used what I had handy.)

Very nice LucZ

Cool, the walking bot must have taken you ages to build. I think we're forgeting the master of all buggys Stefan. He had Bigfoot working a long time ago I was only 6...
