Sofirn SC31 PRO, New Anduril Flashlight

[pennzy]

The charger in the SC31B that I gave away was a little weird too. The light turned green at about 4.something but it continued charging for what seemed like forever. Finally it stopped charging(I was watching it on a USB tester) at about 4.17 volts. It didn’t overcharge but it also didn’t stop when the light turned green either.

I can confirm the Pro is FET+1. It follows the design of the SP36, as they claim they are running the same exact Anduril version as for the SP36.

I pulled the driver. Weak glue holds it in place. 4 wires to the side switch. Used a solder pick to push down on the driver thru the LED+ wire hole, no hammering, just pressure - didn’t damage anything. The driver has Chinese lettering on it, based on the SP36 design.

Think mine reads voltage high as well. Sounds like all the differences reported read high.

Thank you very much Tom!!! :+1:

did you take any picture of the disassembly ?

Just received mine, there are no apparent flaws visible like misaligned charging port or foggy lens. As it uses FET+1 driver, is it safe to run it with 30Q or VTC6 I have laying around?

Which USB tester do people recommend please

Ran mine first few hours on a topped-off 25R (more current that the above), so should be fine there.

Yep, can post this eve.

This is what I have so far:

Thanks Tom E. This is helpful.
Do you have to de-soldier the switch wires to pull the driver out?

@Nooner

Thanks Tom E. This is helpful. Do you have to de-soldier the switch wires to pull the driver out?

I didn't for the pics. Dunno yet - didn't take the switch cover off yet - sometimes you can squeeze the switch board thru the hole. Even if you can't, I've dremel'ed out the hole a bit to make it fit thru on other lights. You could though leave it like I have it to re-program. You can get access to the MCU this way. The FET is somewhat buried behinf the USB-C connector.

The springs don't seem to get fully compressed on a flat top cell, so could probably pick up some power by adding bypasses.

The white stuff is thermal grease, not glue - actually looks like decent quality - moist, right amount applied.

Thanks Tom E, your pictures and your Description in post #150 are really really helpful. I ordered 2 SC31 Pro, i think I can try one for experiment/learning , I’m interested in Anduril-2

That’s a really good news!

How many lumens at minimum of ramp?

[TheAuditor]

Just got mine after a hold up in customs. Really impressed. Excellent value and no issues noted. I will order another.

[McCatface]

Got mine in 5000K as well. Great value overall, great tint with no green. Sharp fins and sharp lanyard hole, as is tradition. Lanyard hole doesn’t align with anything like it does on my FC11. Also, not happy with the smooth reflector. Thinking of trying to put OP from FC11 or a TIR. All in all, my new EDC with a short tube. Just need that deep carry clip now.

Btw, I added voltage cal to Anduril, but only to the 2019 version. TK changed the voltage reading quite a bit since, so it would take a little time to port. After years of frustratingly voltage cal’ing each individual mod light for Narsil, finally built it in to Anduril.

I got Anduril working like Narsil: 3C to voltage, 2C next to temp, 2C next to version #. When you are in voltage reaging mode, 4 clicks to calibration.

Maybe this could be a worthwhile feature to incorporate into Andúril 2.0? I talked to Sofirn about the importance of an accurate thermal calibration today. As it’s probably a PITA for any manufacturer to do the factory calibration for each single flashlight, it will need to be highlighted much more in a „Getting Started“ section of the manual. Adding a voltage calibration would fit into this section seemlessly.

AFAIK, or at least based on the current draft of Anduril 2.0’s documentation, voltage calibration is included: https://bazaar.launchpad.net/~toykeeper/flashlight-firmware/anduril2/view/head:/ToyKeeper/spaghetti-monster/anduril/anduril-manual.txt

Anyone else find it disappointing that a “Pro” light with perhaps the quintessential hobbyist’s UI is still glued together?

It’s not like there’s a thread with perhaps the most loyal customers asking for Sofirn to reconsider that practice…

[Vamko]

According to Sofirn, the button LED turns red when battery is lower than 2.8V. I am thinking, does it make sense? 2.8V sounds too low to me, at 2.8V battery is basically empty.

You mean the blue stuff? If you read the description of blue Loctite, it's the mildest form of Loctite there is:

Guess it's still glue...
