I fly a 1967 Piper Cherokee 180 out of Rockcliffe Airport in Ottawa Canada. During the winter months, I need to preheat the engine of the aircraft using an installed electric block heater. This requires someone going to the airfield and plugging the aircraft in the appropriate number of hours prior to most winter flights. This can be many hours.
This project integrates easily available commercial products to remote control the engine preheater. This project does require that your airfield has WiFi available out to your aircraft.
This is a very easy project to do especially if you're a pilot. You've done much harder things to get here.
The instructions are very easy and the embedded YouTube video walks through the whole procedure.
