On going project of mine.
Been evolving as I've thought of new things I wanted in a pocket light.
Uses a XML-T6 (must be one of the few people around that actually prefers a neutral to cool beam). Driving it at 1 amp max in current version. I was running the earlier ones at 2 amps but the difference in brightness wasn't great enough to put off the difference in heat dissipation and run time.
Driver is from a X-light micro running a P-type MOSFET. The X-light has to be my favorite interface with the infinitely adjustable light levels and out of the way strobes.
1300Mah Lipo with onboard charger and a micro USB port.
Couple of Neodymium rare earth magnets. More handy than I first thought they would be.
Inside is pretty ugly with the individual boards wired together. Working on a single circuit board now that I have the electronics tuned in.
I have the next gen case partially put together, sticking with brass but has a better latching mechanism and much cleaner front end and a better gasket.
Progress has kind of slowed down since I put this third version together. It actually works so well and has come in so handy, I haven't had the motivation to do all the work it's going to take to get to next level.
