So I was thinking about how I was going to drive my first Mag mod and figured out a pretty “cute” way of doing so with a Nanjg 105C.
You may be wondering what could be special or difficult about this…
I wanted to remove the large factory Maglite switch assembly because it is plastic and is a waste of valuable thermal capacity. I also didn’t feel it’d be worth all the machining and effort if I split the heatsink and put a driver cavity between the switch and LED. So I was determined to use a “normal” battery+ to driver and driver to GND configuration (i.e. battery making direct contact to driver and driver mounted on grounded material). A tailswitch mod was out of the picture on this one because it’s a 3 cell. So in the single side switch Maglite application this becomes difficult if you demand these things and still want to switch modes without miles of looping high current wire.
Here was my solution. (there was a bonus perk too)
Bend up the Vcc pin on MCU and wire it to a reverse clicky who’s other end is attached to LED+.
Result is standard UI and virtually no current through the switch!
Disclaimer: I’m not sure if there will be any leakage current through the 7135s but I couldn’t detect it with my setup.
