Last time I did the Hot wire foam cutter but I missed the temperature control. So that's why I made a simple PWM control. The whole project was based on Arduino ATtiny85 Digispark. For this project I only needed three pins, so the ATtiny85 is fine. Also I carried the wires in the PVC pipes.

Step 1: Components

  • Arduino Digispark ATtiny85
  • Plastic box for electronics
  • Some wires
  • IRF530
  • 5 x resistors 1k ohm
  • 2 x resistors 100 ohm
  • 1 x potentiometer 10k ohm
  • 2 x BC547
  • 1 x LED 3v
  • 1 x 7812
  • Hot wire foam cutter
