Yeh, most magnets are a simple Nd-magnet disc that sprays magnetism all over the place.

What you need is a shield or guide, like stick-on grounding magnets for welding. Got one face of the magnet that sticks to the piece directly, and a cup that goes around it stuck to the other face, so the field only “jumps the gap”.

The magnet in the Lumintop "Tool AA 2.0" optional twist tail cap is mounted under a removable tail cap battery spring and replacing the magnet with a spacer is easy (I used a button from an old shirt for the spacer).

The "removable spring design" while not ideal for high current lights would most likely function adequately in the proposed AA/14500 compatible "Sofirn SP10S BLF edition with Andúril".  I do not have access to a Sofirn SP10S and do not know how the tail cap is currently constructed.

How many flashlights does a "real man" need?

None, real men are not afraid of the dark.

The current tail cap is very thin, probably not enough room to add a decent magnet. For the SC31b, the optional magnetic tail cap is thicker to provide room for the magnet.

Definitely interested in one, possibly two. If there’s an option of no magnet in the tailcap, that’s what I’d prefer. Or, a removable magnet.

If SP10S Anduril version is allowed to only work with 14500 battery, it is easy to fulfill. But it has to work with both AA and 14500 battery, it takes time.

I personally am fine with 14500 only. There isn’t really anything out there like this even with 14500 only. I’d hate to see this project fizzle out because the AA requirement is too hard to get working.

Adding AA support would still be a good update down the road if you could keep working on it while producing a 14500 only version in the meantime.

Happy with 14500 but how long is the wait for final production Barry?

Are there other advantages to supporting only 14500 batteries, like lower price, or better driver efficiency?

I would only use 14500 batteries in mine. AA support would be useful when giving this flashlight away as a gift, but I would be happy without it.

A BLF-approved user interface for a AA compatible driver is one of the grails of BLF for many years, I would not easily like to trade that for another li-ion only driver, even when that saves months. I would be happy to still wait a bit if I know that Anduril+AAcompatibility will eventually happen.

Agreed. If It supports AA I am interested. Would make it a nice backup light for in the car. Heck, even the driver would be enough reason to buy the light!

Magnetic tail would be nice. But an indicator light is nice too. Hard to have it all I guess..

Anduril is not suitable for AA
Anduril is not suitable for flicker free firefly levels
Anduril is full of blinky and clicky stuff that I dont want.

The Nitecore D10 Piston Drive UI is a ramping UI, like Anduril, but it does not require LiIon, and it does support firefly levels. There are no electronic flicker and flash modes (“candle” and “lightning”)

soooo… if Sofirn wants to build a light with a Ramping UI, but NOT Anduril, I think a D10 style driver would be suitable for an AA light.

FWIW I would likely only use 14500, AA compatibility would only be a bonus for gifting purposes. If the AA leads to poor low level flickering I would rather not even have it and focus on maximum efficiency 14500 support.

it is Anduril that has a problem with low level flickering, using LiIon.

AA is not the cause of Andurils inability to support flicker free firefly levels.

I’ll amend my statement, If the low levels are flickering I am out. Smile Like I assume most of us I use the lowest levels most frequently. If it isn’t in a blinky mode, it shouldn’t.

Would NarsilM V1.2 / V1.3 work with SP10S? Will there also be increased chances of flickering low level modes as stated for Andúril? How about RampingIOS V2/V3 which seems to be a stripped version of Andúril?

Hum, I guess I will have to put some things in perspective here jon_slider Wink
1 – “Anduril is not suitable for AA” – That’s why the team is working on it, to make it suitable for AA batteries (if it becomes feasible technically and technologically). And if this is accomplished, we may be seeing a breakthrough in flashlight “world”, specially emerging from a flashlight forum and a small flashlight company Wink

2 – “Anduril is not suitable for flicker free firefly levels” – Although I am not expert on this, I do believe that the people working on this driver will probably test the driver/FW to avoid that the lowest levels will have flickers, even working with AAs. I think that maybe we will not get extreme moonlight levels, but I’d be ‘happy’ if the lowest levels are close to the ones in the FWxA flashlights or even similar to those in allowed by the Bistro HD OTSM.

3 – “Anduril is full of blinky and clicky stuff that I dont want.” – I may agree with you on this, although having a candle mode could be nice on a AA light Wink

4 – “The Nitecore D10 Piston Drive UI is a ramping UI, like Anduril, but it does not require LiIon, and it does support firefly levels.” – Although it may depend on the model we have, my D10 lowest more on AA battery still produces more light than my Tool AA with Bistro HD OTSM (on 14500), being both levels good Moonlight levels, but not Firefly. Still, both these 2 flashlights produce more light than the Sofirn SP10A on its almost firefly level. A true firefly mode on a AA light can be found on the Reylights (that supports AAs and 14500s).

Sofirn SP10A >>>> Tool AA >>>> Nitecore D10 (all in their lowest possible levels)

This said, I guess some concerns are natural, other are more preferences of course, but there seems to be a long way to go adpating this firmware to AA batteries, and we may be surprised by the end of it Grad

I trust the people involved in this project, and thank them for the time invested in it. I am sure they will get us a good compromise between quality – power – usability – efficiency – looks – price Wink

Think of it as easy-access candle-mode. Silly

you are right Smile
My D10 lowest mode is 1 lumen with sw45k
it is actually the D11.2 firmware that produces 0.01 lumens minimum

> having a candle mode could be nice

not for me Smile
to me, candle mode is just a fancy word for flicker, it has no real resemblance to a real candle

> I’d be ‘happy’ if the lowest levels are close to the ones in the FWxA flashlights

clearly you, and others who “love anduril” do not require firefly Smile

carry on… this is not the droid Im looking for

This is really an issue with driver design (and instability at very low outputs) rather than the firmware. Anudril itself uses PWM fast enough to be completely imperceptible at every step AFAIK.

I don’t see why Anudril couldn’t be adapted to a driver that solved that issue – however lights and drivers with extremely low moonlight that is flicker free generally aren’t cheap, because the drivers that can accomplish this are difficult to engineer and more expensive to produce.

The entire point of this light is to get Anduril on a AA-sized light, so not sure what the purpose of criticizing the blinky modes of Anduril (which I woud rather do without personally too) would be??

The firmware doesn’t care for the power supply.

jon_slider wrote:

Why not? It just tells the driver “I want 1/1024 brightness” and the driver is responsible for reaching that goal. Don’t confuse bad driver design with the firmware.

jon_slider wrote:

Then don’t buy a light with such modes or don’t use them. This project is all about developing a driver that supports Anduril.

But it is not Anduril.

jon_slider wrote:

It’s all about the driver. If it can power the microcontroller, it could potentially run Anduril. Just that Anduril is developed for ATtiny microcontrollers.

jon_slider wrote:

See above, this has nothing to do with the firmware, but with driver design.

Maybe jon_slider refers to the recent issues with the KR4? The driver uses a FET as a linear current regulator. Its main component next to the FET is an opamp. This opamp gets it’s reference voltage from Anduril via a low-pass filter / integrator. For every linear regulator you have to set a lower and upper bound in the design. Level 1 and 2 out of 150 set the reference to 0 V. At this level the opamp is not able to maintain stable regulation.

How could this have been fixed? By using two regulators. One for very low currents, one for higher currents. But this needs more space on the PCB, increases the BOM and thus is more expensive.
