You can try Sofirn Q8 on aliexpress or amazon
the sofirn is coolwhite emitters tho, perhaps he want the original ?
Does anyone have good sources for a diffuser for the Q8? A warm colored one would be perfect.
Fenix AOD-L.
I have a problem. After removing the batteries (for charging), the flashlight forgets the custom setting of the temperature of the temperature control and uses the factory setting of the temperature of the temperature control.
What to do? Or is this the norm?
There is a bug in the software that shows up on very few lights where it doesn’t always save changes made in the menu after battery power is reset.
Iirc it will remember eventually, it may take a few tries plus it helps to cycle the light on/off and basically use it normally before disconnecting battery power.
I think it’s referred to as the Narsil memory bug.
Yes, it should remember eventually…
To completely fix it though, it would be necessary to flash new firmware onto the driver. This requires some extra tools, but the tools are cheap and the firmware is free and the Q8 is exceptionally easy to flash.
A few hours of tests, the results are strange. Thermal control memorized temperature setting. Stepdown worked in any mode, for a given temperature. But as soon as I pulled out the batteries, a change occurred. In turbo mode, custom thermal control remained, in any other mode, thermal control is 7-8C lower. For example, a turbo 57C, in another mode 49C. And so every time you remove the batteries.
Is there a topic with instructions on updating the BLF Q8 firmware and links to buying equipment?
This stuff is too complicated for myself, but I kinda want to learn so I’ve been keeping track of things.
Try this link for parts.
Here are some videos.
Here is a thread on it.
Thanks for the help!
It seems to me that the error is common, but it is difficult to notice because of several reasons:
- very few people change the settings;
- the factory setting of thermal monitoring (55C) is quite reasonable, but the calibration of the sensor is different for everyone (I have about ~ 48C);
- not everyone has the necessary equipment to control the parameters of the flashlight;
Di_Joker, there may not be much need to run tests because the issue is already known and was fixed in a related firmware in 2017.
So the issue is pretty well-understood, and updating the firmware should fix it. The original Narsil firmware is mostly abandoned though, since Tom has been too busy with other parts of life to maintain it. So fixed lights are running Anduril instead. It’s not perfect either, but it’s actively maintained and doesn’t have any known eeprom bugs. It also has quite a few more features, and is easier to modify if you want to customize anything.
ToyKeeper, I have seen mentions that in Narsil 1.2 (ROT66) there is also a memory error. Narsil is especially good because in addition to the ramp there is a mode with fixed brightness steps, for some it is very very important.
Yes, the first batch of ROT66 lights used NarsilM 1.2. Later batches switched to Anduril — to resolve the memory error, to get more features, and because Fireflies thought Narsil was too complicated. Both offer a choice of smooth ramp or fixed brightness steps, though the method differs.
Narsil:
Anduril:
I have a bunch of NarsilM forks to merge together, and I think I also have a patch to fix the memory bug, but it’s going to take a while and requires a lot of code reorganization and testing, so I’ve been procrastinating. Since Narsil isn’t really maintained any more, the main point of the merges is to simplify the process of GPL compliance, keeping all the forks in one place. But it’s not likely to get any more significant updates beyond some branch cleanup. Development has pretty much moved to FSM, the toolkit on which Anduril is based.
ToyKeeper, Yes, I somehow missed that in the new Anduril there are fixed brightness steps. I have no steps on the Emisar D4 with the old version Anduril.
In any case, on my Q8 Narsil 1.0 and I will be interested in doing the tests. If I can get a positive result, it may be useful to someone else.
Unless you flashed the firmware, the Emisar D4 doesn’t have Anduril. The Emisar D4, D1, and D1S ship with RampingIOS V2, which is a simplified fork of an old version of Narsil. It only does smooth ramping.
The Emisar D4S ships with RampingIOS V3, which is a simplified fork of Anduril. It adds some things, like Anduril’s fixed brightness steps, but it still lacks a lot of Anduril’s other features.
The only stock lights with Anduril so far are from Fireflies. However, there should also be some soon from Sofirn and Lumintop. And maybe Emisar, if I can ever get Hank to use it.
ToyKeeper, Oh, how much I did not know. Thanks for the elucidation.
Anduril has that too. You can even configure the number of steps.
In Ramping:
Double klick to Turbo, then double klick again
In Modes:
Hold
And the FW3A with Andúril will be released any moment.
(or in a few months)
