I'm looking for ideas for a stand alone timer to turn on and off a remote shortwave or BCB receiver and tape recorder. No AC mains available. Switching requirements no more than about 5 amps. Some Radio Shack digital AC timers actually run from batteries - run even without AC present.

The 61-1060 wall wart type (and its more expensive 7 day big brother) won't click, because the relay board is powered by the AC plug, but the timer is on a seperate board with only two wires between it and the relay board. Easily hackable, IMHO. (Replacing the click dome pushbuttons with tact switches is recommended, too). Mark Zenier Washington State resident |
