The Glow Plug Driver uses Pulse Width Modulation (PWM) - basically turns the power on and off really fast so the glow plug doesn’t burn up. 

You can use pretty much any microcontroller such as Arduino, ESP8266 or PIC chips to control the PWM.

A good source for a 12V power supply with enough power is old computer power supplies—or a 12 volt lead acid battery from the car will work as well.
