Are there any systems that could be a hobby project that could project a star field using lasers. Not the kind of star field that is random, by shining light through a filter. But a star field that is calculated and then projected (Like a planetarium) I want to be able to project about 2,000...

Hi, I am looking for some help working out the best solution for a little project I am doing. It's a simple star-field generator written on a raspberry pi, with or berating binary systems and starting to introduce some basic gravity interactions. I always had it in mind to eventually project...

OK so new to laser scanners and controllers so just wanted to ask for some conformation. From what I understand most laser displays work by using a scanning process Each laser is swept back and forth using Galvo's at a set speed. By knowing how fast the laser is scanning and timing the laser...

Hi, Just wanted to say hello, and say why I am here. Really quite new to Lasers, can tell you how laser light is produced at the atomic leave as electrons jump between energy states, but I have to say my knowledge really is from the science side and not at all engineering. My wife got me...
