Catching up with some electrial projects
This circuit uses a Set / Reset RS flip flop made from Nand logic gates to control a relay which controls the polarity of the voltage applied to the Tortoise motor. One pole of the switches on the panel are wired a little differently so that in one direction the all send the thrown polarity and in the other they all send the aligned polarity.
Another electrical project I am working on is a power supply for the LED lighting over the Wesso section and the staging yard. The laptop power supplies I have been using in other areas won't handle those and I have been using my bench power supply but that is needed on the bench.
