My friend James likes to play with fire and burn stuff. It’s a bonus for him when he can use previously unobtainable technology to do so. Recently he has been buying Casio XJ-A140 projectors
for the purpose of parting out the 445nm Nichia laser diodes(24 of them!). He has sold some of these on eBay to others who don’t want to tear into an $800 projector but recently he hooked one up to an LM317 regulator to see what it can do. What you see in the pictures is the result of roughly 1.2 watts of output. The visible blue light is totally dangerous and even the reflections could cause permanent eye damage but I’m SURE he locked away his kitties and wore protective goggles(yeah right).
