Sheltering in place and being somewhat bored I bought a used projector for cheap with 2300 hours and harvested 24 x M-140 diodes that work very well, I am driving 4 laser diodes in series @ 1.6a using a LM338 as a current regulator using 0.8 ohms across the adj. and output pins and 8 x 18650 in series,.....my expideted mounts are angle brackets giving me X and Y adjustment so I can converge the beams where ever I want to.........thinking about what else I can do with all of these diodes.......maybe knife edge a bunch ? Anyway just goofing around and thought I would post a couple of pics.
