So last year I bought a 4 pack of these little 2xAAA LED pen lights from home depot for like $10. The intention was to use the red and blue ones as laser hosts with diodes of the same respective colors. As other projects surfaced, these got put on the back burner until I had the parts. In the months since, I've just been saving bits and pieces from other units, ordering other bits, so on and so forth. Finally got around to going through everything while cleaning and reorganizing my home office this weekend. In doing so, my interest in finishing one of these was renewed and last night I managed to get everything dialed in and squeezed into the host. Sorry I didn't get photos of the internals, but I'll try to do that at some point later then add them.
Unknown 445/450nm diode and driver, case negative. Diode was already mounted in a 12mm brass module, turns out the back half of a Aixiz module clone works perfectly as a threaded lens protector after getting the brass module focused. Used a piece of solid core wire to extend the positive contact down into the tube a bit further so i could use a single 10440 instead of dual AAA. On a bench supply, it was pulling between 250-330mA without getting very hot. Metered on a no-name pocket LPM @ 150mw. This is likely in the same ballpark, but I doubt it's a very exact reading. Either way, I'm happy with how it turned out and was excited to share the finished product.
