I'm just trying to fix the LAD's on some technobeams. I got some 5mw lasers and they are a little bigger then the stock mounts. I made some mounts that fit nicely, BTW they are 5v and when I plug them strait into the lead coming from the pcb they don't come on? on the stock setup there is a small board that the LED is on, I thought that the res,cap,dio where just for the LED but guest I was wrong! dose anyone have a schematic for this small board? The reason is that one of the lights did not have a LAD. It seems that I could make it with some parts laying around.
I using some aftermarket lasers that are 5v but for some reason when I plug them directly to the lead from the main board they don't come on, but they do work if I plug them into the second small aux board? again I replacing them on a few but I have one that never came with a LAD so I'm looking to make the small aux board. I'm thinking that I wouldn't need to use the LED part of the circit. to look at the traces they loop around to the LED and back the the laser. So I need to know what is needed for the LED and just what is need the run the laser?
