The Arduino is great, you can make it do pretty much anything you want. I wanted a tripwire. This is just the circuit and the code, you can use it for quite a few things, like a trigger for a camera, or you could make it shut down your computer if someone crosses it.When I have the time, I want to hook it up to an electric airsoft gun with a relay and have it shoot you when you break the beam. I suppose I'll add to the Instructable when that happens.So let's start!
This machine is designed to make the laser engrave in wood and opaque plastic, having an Arduino and the GRBL as machine automation basis. The machine axis are just the X and Y axis, which move a laser with power 1w 445nm, and this article aims to provide everything you need to make, without waiving of mechanical and electronic knowledge. With around 170 euros can make one.My portuguese blog: www.logicamecatronica.com (like my blog on facebook please)
