Got my remote engine heat switch set up, as seen in this photo.
All the parts are in an old plastic tool box I had around.
On the left is the circuit board of the Velleman remote switch kit. It uses a photocell pointed at the cheap pre-paid TracFone next to it. When I call the cell twice within one minute and the photocell detects the phone screen lighting up when those calls arrive, it trips the relay supplying power to the Reiff pre-heater.
Power comes in on the green extension cord, which I tapped into for phone charger power, detector circuit power, and then to feed the relay. Power to the pre-heater continues out the green cord to the right.
Works well at home - now to take it to the hangar!
