Sofirn SC21 mini

afaik, it is only the SP10 Pro driver that is sold separately.

IF you can buy the SC21 Pro driver (not SC21 Mini), I hope you try it and let us know if it works better for you.

fwiw, that review is not for the Anduril version of the SC21…

Very much looking forward to seeing the results of getting Anduril 2 running on these!

As for regulated/non-regulated output. here’s my output measurement of the pro using ceilingbounce in case you missed it: Sofirn SC21 mini - #161 by Verodin

Is this Anduril 2? If so, can someone ask Sofirn to reflash or use this going forward? anduril.2021-08-31.sofirn-sp36-t1616.hex

Why? That’s a pretty old version.

I haven’t kept up with Anduril firmware for all the various lights. Hence the if so part of my post.

Since it doesn’t seem to be Anduril 2, we will have to wait for someone to compile one. At least we know anduril.2021-08-31.sofirn-sp36-t1616.hex can be used to create an Anduril 2 firmware since Sofirn seemed to use their own version for this light

I think what SammysHP is trying to say is that Sofirn should be using anduril.2021-12-13.sofirn-sp36-t1616.hex since that is the latest official build of Anduril 2 that will work

gChart, any chance that you could design a Programming Key for the SC21 Pro? If I understand correctly, it only needs three pins, but the key has to be five pins wide: (GND) (VCC) (blank) (blank) (UPDI). Too bad Sofirn didn’t put them together so that your UPDI key could be used.

I’m confused now

So it seems the latest Anduril 2 works but has problems?

Look at post #207. I improperly erased the MCU and that was causing some odd issues. The latest Anduril 2 build works great after I did a factory reset.

Who do we contact at Sofirn to see if Sofirn can use this build for future lights?

Please no, there are more recent versions and Sofirn should talk to a dev (ToyKeeper) first.

Haven’t kept track of changes, but are there any fixes/additions that apply to the SC21 when using a newer version? If not it won’t matter using an older version.

Don’t recall if this was mentioned earlier; the TIRs Convoy/Simon sell for the S2+ also fit wonderfully in the SC21 without the glass lens and emitter gasket just as they do in the S2+. The head will screw down more for those who don’t need the warning label to line up :nerd_face:

I grabbed a random beaded TIR from my stash, probably a 15deg, and honestly wish this were an option from factory, it’s great.

Great info! Congrats and thanks

fwiw, I just tried it, and no go: (maybe cause dedomed)
.

Awesome to hear! Thanks for sharing

Apologies, I was mistaken; the TIR was likely a 45 or 60 deg beaded TIR, one of the jobbies listed here: 3.04€ |10/25/45/60 grad TIR objektiv, streifen led objektiv für XML XML2 LED|led for|cree ledlens cree - AliExpress

I just tried the 10 and 15 deg TIRs and the beams were rather lackluster as you’ve shown, I’m also using a DD 519A.

Took some more images comparing the stock reflector with the Convoy beaded TIR

thanks,

glad to hear the 45 degree works better w the dedome 519a, than the narrower beams…

much appreciate you providing the link, I went ahead and ordered a few different Tir to test…

New flashaholic here. I’m new to this hobby. I started out with a Nebo Torchy (wich is dangerous when you tend to walk around with ferrous metal shavings in your pockets), advanced to the SC21 5000k and just added a SC21 pro to the collection.

I flashed my light with anduril.2021-12-13.sofirn-sp36-t1616 according to Adair21s instructions. I soldered to the pads and used an FTDI breakout board, two resistors and a diode on a bread board for the flashing.
At first I had slow ramping. After a factory reset it started ramping normally.

Fiddeling with my light, I found out that the bezel isn’t glued (seems like they have skipped the glue on the green versions.)

That led me to order some TIR lenses from Convoy to do some experimenting.

At the same time I ordered an 2700k S2+ LH351D (I also have a 4000k SP36 BLF incoming). Into the rabbit hole I go. :slight_smile:

congratulations… im still working on that goal… for others interested here is the link to Adair21 instructions

> seems like they have skipped the glue on the green versions

I also had no glue on two green SP10… a red one required heat to open.

It's nice to see you, Yngvej!
