Argon laser power supply from surplus switchmode PSUs
There are numerous power supply schematics at Sam’s Laser FAQ, but many of these are aimed at USA 110V mains supplies. As I live in 240V-land, I needed to build a proper PSU, and didn’t like the idea of having to use a huge, hard-to-find, hernia-inducing transformer, big smoothing caps and hot linear regulator, and decided that it would be good to be able to use a switchmode power supply (SMPS), which would be lighter, smaller and more efficient . Large SMPS’s are readily available very cheaply in the surplus and Radio Rally (Hamfest) market, as they are mostly of little use out of the equipment from which they came - when was the last time you needed 5V at 80 amps
