ESP32-Powered Laser Projector Brings Retro Vector Graphics Back to Life A new DIY laser projector project from breq.dev is getting attention in the maker community for mixing old-school vector graphics with modern embedded hardware. Built by Brooke Chalmers and Mia Kiesman, the system uses a pair of galvanometer mirrors to steer RGB laser beams and draw graphics directly in the air. Instead of using a normal display panel, the projector creates smooth vector-style… |

Wireless Audio Transfer Using LASER Light In this article, we are going to discuss how to transfer audio through laser light. This is a fun little project, and the concept is similar to what we see in fibre optics cable. We will use a laser light to send data from one point to another. To be particular, in this project here, we are going to transfer our voice from one point to another by shining a laser light on a solar panel. This… |
