1 × DC/DC converter 10..12V -> 5V LM2596 based power converter (or similar)
1 × DC/DC converter 10..12V -> 12V LM2596 based power converter (or similar)
1 × 500mW Laser with lens, casing and driver You need the cutting Laser. It should have a 12V input and a 1..5V modulation input for adjusting the intensity
1 × Security switch Safety first! Use these red mushroom shaped emergency switches. If anything goes wrong while cutting, hit the button and everything should be turned off.
1 × Wood plates The base plate is made from wood and cut into shape
