The transformer gives me about 20 volts DC out. Dropping 8 volts at 1 amp is just a lot of power to void with a resistor. I'd like to avoid having that much waste heat in the unit. I do have an old power brick, but I was hoping there was some small switching board that people had had good luck with. Maybe the brick is the best option.
