Hi everybody!
so i was in south dakota last month and while i was there i found this little flashlight in a store there, and for only $8.50 i figured i would get it to see if i could build a laser out of it, and it seems promising for a low power build. it holds one 14500/AA battery.
here it is compared to a 501B:
it is around 115mm long, 22mm wide at the head, and 17mm wide at the tail.
here is a picture of the head taken off and the "pill":
the black plastic ring with threads is sort of like a pill. it held the LED and reflector in place, along with the LED driver/contact board. on one side it has a 15mm opening, for the 15mm PCB board the LED was on. on the bottom it has a 16.8/17mm opening for a driver/contact board. there is not a lot of space, but there is enough to make a good laser.
you can see that it has a "thing" for contact between the clicky button and the contact board, meaning that no extra work is required to make contact between the side clicky and the driver/contact board assembly, in fact the only thing required for the build is taking apart the head! it is also possible to remove the clicky button if you have to replace it, but it seems to work very well so i wouldn't worry.
id say the best way to make it work is to make direct press fit heatsink for the diode, then get a 16.8mm driver to put in the plastic pill and hook it up to the diode. im not sure how you would be able to make contact between the host and the contact board, but i'm sure someone can figure it out.
any other questions about the host i could probably answer, so if you have any just ask.
