High Voltage Igniter

Here is an easy to build high voltage igniter that can be made fairly cheaply. Ignition coils require their 12v power source to be interrupted for them to release the charge on the high voltage side. Inserting a simple 40amp car relay and wiring it to turn itself and the coil off and on again repeatedly produces a high voltage spark I use to ignite my pulse jet engines. Below is a list of parts needed. I sourced most of it from Amazon and there are affiliate links provided to the exact parts I used here in this video.
