DIY Laser Image Projector (100ft+ Range!)

I created this unique laser device which can project raster images, like Gifs, over long distances. It uses a combination of a high speed rotating mirror and a galvo to draw each frame. With a resolution of up to 320x120, it’s not exactly HD, but the aesthetics are incredible! 0:00 - Intro 0:49 - The plan 1:49 - Raster vs. Vector images 2:14 - Safety 2:25 - Upgrading the old laser projector 3:22 - Improving the resolution 5:47 - The vertical axis 7:17 - Building the prototype 8:26 - Resolution limitations 9:28 - Adding more colors 11:42 - The RGB laser 12:22 - Turning images into data arrays 12:58 - My janky setup 14:31 - Designing a PCB 15:07 - PCBWay Sponsorship 15:36 - PCBs and CNC machined parts 15:51 - The physical design 16:38 - Indoor tests 17:52 - Outdoor tests 18:48 - Reviewing the device
