A teenager came up with the design for this $220 laser engraving machine. Yay Arduino!

Freaking impressive!

To drive the machine, he used an Arduino UNO with two NEMA-17 stepper motors and stepper motor drivers he got from AliEXpress. By using AliExpress, he was able to keep the component costs down, with the entire thing costing about US$220. The laser is a 1.8W 445nm module.
