Sofirn D25s driver flash?

I was wondering what mcu this headlamp runs, and possible “upgrade” UI may be flashed into it w/o any actual hardware changes?
I wont be around mine until the weekend to look at it.

I have recently got into some light caving, and (believe it or not) this can be too much even on low at times.

I have several of them from camping. Great for that. My thoughts were to give it lower mode options (or Andurial would be GREAT) and pot the guts after.

I know I could buy something else, but where is the fun in that?

Anyway. what say the gurus around here?

I think gchart had a swap for just the MCU to enable anduril, and quadrupel has a few drivers for it that will run anduril - that’s what I’ve done with my D10 and D25S. But afaik nobody has flashed the stock MCU.

I had seen Quadrupel’s drivers. I have never done a swap on a stacked driver set-up w/ built-in charging. Not real sure how to go about it, though I could probably figure it out along the way.

I will have to find gchart’s mcu swap. That sounds like just the ticket realy. Plus it would give me a “reason” to get a reflow station.

Interesting, I recently got a D25L (2x LH351D 5000k) but miss the battery voltage checking functionality of Anduril. I suppose I’ll look for that MCU-swap post too :smiley:

To swap driver you have to de-solder and solder back 4 wires, no mcu swap needed . Plus you’ll have lighted button and constant current output up to 350mA. Its a classic Fet +7135 driver.

That’s true, for a MCU swap you have to remove the driver board anyway… Do you sell an assembled drop-in Anduril replacement driver?

Yes, i can build 10 drivers for this moment. PM me. Cant get attiny85. All out off stock or cosmic price :frowning:

Reichelt Germany has or had them. Got some two weeks ago.

mtnelectronics has them. Shipping to you may make them fall into the cosmic price range though.

What changes did you make to the Emisar D4 ui ?

Wondering if I might be able to get a driver from you minus the attiny85, and get that from Mtn, with the ui on it.
I would end up having to solder the mcu on still, but may be worth it for a ramping ui with low modes.

But if I do one, then I got to do the others right? :person_facepalming:

And the sst40s would have to go, replaced by sst20s and tir optics.
The LH351Ds could stay in the other ones.

Hmm, so much for low budget build(s).

But then you’d have a custom light. My build of one of Quadrupels designs was worth all the money. And the pain you’ll suffer if you do this for the first time :smiling_imp: .

First headlamp maybe, but far from my first custom light. Do wish I had a lathe to make my own custom host though.

I like my D10 so much I’m doing it again to my D25S - bought it specifically for the mod.
