(...) Yes, though the things to think about are the voltage drop across the diodes or other devices and the amount of power required. If only low power devices were being driven, such as the IR chip on its own, a simple bridge rectifier made from (...) (20 years ago, 14-Jul-06, to lugnet.robotics, FTX)
