Sofirn SP10 Pro (AA/14500/Andúril 2) - now available!

Skills: very detail oriented, patient, and decent soldering abilities

Materials: attiny816 or 1616, my PCB, solder paste, desoldering braid or solder sucker

Equipment: soldering iron, a hotplate or hot air station, UPDI programmer

Process:

  • File any excess off the PCB and clean it up
  • Apply a small amount of solder paste to the PCB
  • Carefully align the attiny on the board
  • Reflow it with a hotplate or hot air
  • Touch up any solder bridges with your iron
  • Flash the firmware onto the attiny
  • Remove bezel and reflector from SP10S
  • Desolder the LED wires and gently push them into the holes they’re fed through
  • Push something like a toothpick through one of the holes and up against the outer rim of the driver, gently tap on it to break the driver free (it’s lightly glued in place). Try not to damage the LED wires or any driver components
  • Take the driver and desolder the two boards (it’s a T-shape 2-part driver)
  • Remove the existing MCU. Hot air really helps here
  • Solder the attiny adapter board in place, paying close attention to orientation
  • Reverse the process to put everything back together

Were it not for the global microcontroller shortage, I’d offer to send you a ready-to-go adapter board. But as it stands, I only have a couple attiny’s left and probably can’t get anymore for several months. That could also be part of the reason that this project has been quiet lately.

now that fwaa is out i dont see point in this… they had their chance.

I partially agree, but there are two big differences:

  • Single LED vs triple
  • AA (NiMH / Alkaline) compatibility

And if you’re really big on side switch vs tail, then there’s that too

Keep it the same size. No onboard charging please. I’m in.

THIS!!
So, Sofirn still has the chance!

Unless they come with something like a renewed EDC05 with the specs we’ve been wanting for this SP10 light, and that gchart mentioned above!

I am also still hoping for an Anduril light that supports AA (NiMH / Alkaline) as well as 14500 Li-ion batteries.

Lights that only support 14500 batteries like the FWAA would not persuade me to replace an 18650 powered light, even though they are smaller, unless they were also able to use NiMH and Alkaline batteries.

Even though I appreciate my hair-trigger tail switch FW3A lights; for EDC purposes, I prefer lights with a stiffer configurable lighted side switch that do not have inner control tubes.

IIRC Toykeeper posted that Andruil only works with lithium batteries so no hope for AA support. I’m perfectly fine with that.

I guess this post (and from then on) can help understanding why this “joy” here in the thread :wink:

:wink:

The entire point of this thread is to achieve - and it has been done successfully - Andúril with alkaline/Nimh support.

The only limitations for anduril are that the microprocessors it currently runs on require a minimum voltage input. How that is achieved doesn’t matter much, and in this case it can be boosted from a AA input voltage.

Feel free to read the thread for more information.

I’ll just leave this here…

FWIW, I did have to add the dual-voltage capability to Anduril2 for LVP purposes.

That is great! Sofirn — make this happen soon.

I’d settle for an SP10s with a basic UI that doesn’t suck. Seeing it run anduril is badass. Maybe they’ll actually do it…

I want one. Oh who am I kidding, one in every color. Very cool.

I would never trade the ability to use alkaline and nimh in this light for the andruil interface. It is a huge utilitarian benefit to be able to use three different batteries. The andruil interface won’t do any for you if you need a light and you happen to have this one with a bunch of alkalines.

Umm… zoulas? Did you happen to watch the video I just posted?

I will take it! (with a tail switch)
give the man a Cigar!

gchart, you Rock!

You are the first to create a hardare combination capable of running Anduril from AA battery.

that is a very nice looking light you built…
congrats,

so glad all the talk is finally over (or not)… lol

OP is updated with the big and great news. :-) I try to get more news from Sofirn at the end of next week. Currently, they face a considerable bottleneck of Andúril-compatible MCUs being unavailable. Let’s hope the supply situation will soon get better, so they can make our dreams come true.

I’m in.

I wonder which of the Andurils we should ask for? They already have a good manual and flow chart for V1 so maybe they’ll want to use the same
