I know the saying "you get what you pay for" but I'm a frugal slow learner. I bought a couple of these cheap eBay drivers with the intent of running 2 diodes off one at about 5 volts. The description was pretty vague, but they were cheap so I scooped them. Well, I led'd 2 of my good diodes double quick because the 1/2 turn pot goes from zero to god damnit in half a finger twitch. Also at 4 volts the driver got too hot to touch but running 2 of my cheap 5mw drivers at 5 volts and cranked all the way it ran cool and didn't cook even one of them by itself... 😠 I should have run a test load on it, but I doubt it would have helped much considering its odd behavior with the lesser diodes. Anyways, if I did something wrong or if these drivers are indeed crap I'll figure something out. Any ideas from the pros? Im seriously thinking about just getting a prefab 500mw or 1 watt unit in 808 for the engraver and buy a better driver for my red from a better source. I guess it also doesn't help much that I'm kinda n00bish to the electronics game. I do have basic knowledge from an extensive background in automotive and tinkering with various things but this micro stuff hurts my aging eyes.
