Servos

In a commercial laser display the laser beams are moved by galvos, these are super fast direct drive actuators that can position accurately an quickly. I haven’t got a set of galvos but I do have some servos. I’m going to try out the servos for a laser based project I’m working on. They’ll be slow – but that won’t be a problem in this project. Also, they have the advantage that I can drive them using an Arduino.servo3

First step, I’ve epoxied a couple of small mirrors to the servo swing arms. I’ll make a jig to hold them into position then I’ll have a go at the Arduino code. More soon.servo02
