The starting point for many UK laserists, the #lasertech self assembly laser kits! I built one from scratch back in the early 2000s, but thanks to #ebay I now have several of these systems. Open loop scanners based on loudspeakers! If we get #lasercamp at #emfcamp, we can bring the #showandtell 🤣 #vintagelasers #retrolasers #lasershows #argonlaser.
