DIY Coffee cup heater that works!
Warning! Pad heats up to 100 degrees celcius.
12V 12W Heatpad (about 11.5V / 0,9A at a 12V/ 1.5A powersupply)
Maybe room for improvement but it works.
Drawing updated after my last build and found issues.
Self switching by cupweight (3 parallel switches)
Room for a IRFZ44N MOSFET and wires (last update)
Used a mini version myself type 2SK2503 MOSFET for switching (10k/100k resistor)
Switches can only hold 50mA although they survive 1A for 2 w
