Astrolux MF02 Mod

On this driver, pin 7 is available to control the LEDs. Pin 7 is connected to the top pads of R1 and R2. For the red LED, I soldered a 47ohm resistor to the top pad of R1, facing away from the bottom pad. I then soldered the red switch led wire to the other end of that resistor. It’s not super robust and I wouldn’t do this on an edc, but my throwers get babied anyway so I’m fine with it.

I was thinking of cutting the springs with lineman’s pliers. Yeah, sawing would also be bad.

The driver is from TA’s thread :

That said, because it uses 7135s, I wouldn’t recommend it for anything but single cell voltages.

I have two spare drivers and spare cell carrier boards if you’re looking to convert, but the drivers do require physical modification. I think with better planning and more precise drilling it would’ve fit better. I also slightly customized Anduril for this, turning off the main led blink at power-on. Looking back, I wish I’d found Lexel’s Oshpark boards thread before I did this project because the MF01 driver is probably a perfect fit.

Also, I think I’m going to put this project on pause until sometime after Christmas. I’m hoping for a dremel. By my estimations, going from 30mm to 28mm MCPCB is losing (π×15²)−(π×14²) = over 91mm² I’d have to file off manually.
