Mod: DX Module, Senkat GB LD, LDO CC board

[chimo]

Here are some pics of a mod I have started using Senkat's GB diodes and an old 3xAAA flashlight converted to take an 18650.

Proto driver board (will be shrunk to fit in flashlight head). LDO Linear regulator (~80-250mA):


Module in Al heatsink slug:


Head:


Parts (anodizing removed on all parts but the head):


Blank PCB


PCB Ready for etching


PCB with some components mounted


Driver with trimmer pot mounted on underside


Driver in head


Laser Module


Assembly shots


All together now


With one Li-ion and the LDO, all I could get out of it was 185mA. This configuration should also work with 2x CR123A or 2x RCR123A Li-ions.

Thanks Mike. I use the sponge method for etching. It only takes a few minutes, saves on acid and it's faster and easier than using a dremel.
