Build a Remote Control for F-1 Shooting Chrony
I found a 1/8" stereo cable laying around in junk box. (like this one

I cut one end off and soldered a NO(Normally Open)push button switch to the
wires connected to the Ground (sleeve) and Ring.
(The Tip is for data output to your PC or Chrony Printer, just leave it
unconnected).
I tied the wire down so it wouldn't break.
Since it's raining here, I hung up a couple of 60Watt Reflector lamps and
started shooting!
