Hi Fellas
Had an old 3D Mag-lite lying around and said your up.
homemade driver FET+1 2S zener mod as I didnt have any LDOs.
Flashed anduril.2020-09-27.blf-q8.hex was amazed it worked just fine with zener mod and momentary switch
with freshly charged LGs xhp70 pulled about 10A at the tail.
used below schematic
cheers 
nice!
I’m surprised to see a maglite mod in 2020. How did you make your heatsink?
Wow nicely done!
Very nicely done ‘nmbusa’ 
Hard to beat a successful mod. It should last a long time.
Hi
made on a lathe and drilled angled hole for set screw
not shown in any pic but changed switch as original rusted years ago due to battery leak.
used 1 of these
