In this video, we will build a super portable and precise Arduinopowered laser engraver. We will explore a new and unusual way of building these DIY machines by using rotational axis instead of linear ones, achieving great precision and unlimited range in a surprisingly small package that can be powered simply from a power bank and controlled wirelessly using a smartphone.
