Great value, many uses
Works fine, great value. I found the label below the connector a little confusing, but after popping the back cover off and looking at the markings on the PWB it became more clear. Also a little puzzled by the 5-30 ma rating. Can it safely source only 3ma at certain settings? If anyone knows, please share. I'm going to drive a 2N3055 with it so I can use some high-current devices. This might be used in many projects - strobe light, spark generator (with auto ignition coil, crude (square wave) audio generator, incandescent light flasher, motor speed controller, etc.
