Can’t believe sofirn didn’t use a better location, or at least make it easier to access. Wonder if the diffuser and tube can unscrew, to have better driver access.
Also, are those 2 sets of flashling pads? Hopefully the small ones are compatible with the TS10 flashing adapter.
I’m not sure how to disassemble it. If it unscrews, it doesn’t unscrew easily.
There are indeed 2 sets of flashing pads… which I thought was odd at first, but it ended up being really handy in this situation. The small one looks like it’s probably the right size for gchart’s adapter, though I couldn’t fit it in to confirm… and the larger set is just the right size for the ribbon cables I happened to have on hand.
That meant the only tricky part was figuring out how to get pogo pins onto a long enough stick to reach inside. And as luck would have it, I found a plastic fork which was exactly the right size and shape! 
If it’s anything like the original LT1S, you can take it apart. I’d rather not have to though. Not my pics:
Doesn’t look too difficult to disassemble enough so that the 2700k 519a can be dedomed. Shame that the battery tube is fixed in place, or not removable otherwise.
Thanks! Those pics look like the LT1S Pro probably uses the same assembly mechanics.
But now that I’m armed with the power of a plastic fork, I shouldn’t need to take it apart.
What’s this device? Is it some kind of multipurpose programmer that can do the job of the gchart flashing key, the hanklight flashing thingy and also flash to different pad layouts?
If it is what I think it is, then can it be used with the ZFlasher app on Android?
The fork is genius, BTW.
It’s the flashing adapter gchart sent me a long time ago for t1616. It’s a jtag dongle which I think he may have replaced the firmware on, to do jtag2updi instead. The t1616 speaks UPDI… which always makes me think of UPDOG.
Gchart’s newer flashing key is smaller and generally nicer, but it’s all-in-one so it doesn’t have a way to connect a ribbon cable. I had to get the old one out for ribbon cable purposes.
I have no idea if it works with ZFlasher. I’ve never tried to flash firmware from a phone.
Ah, thanks for the info.
So the firmware is replaced on a device made for replacing firmware. You people are too clever 
What happens if you plug it in to itself? 
I’m interested in the group buy, but bugs are a concern since it will be the first batch of lt1s pros. Not sure if it’s better to wait for the finalised version.
FWIW, I’ve been rewriting the entire tint and channel handling part of the code, and have 2 of the channel modes working on LT1S Pro now. So in my dev version, it has:
I’m also adding:
… and some extras or improvements:
This new channel system requires updating every supported light though, so it’s going a bit slow. It’s the biggest code change since rewriting Anduril 1 to make Anduril 2.
You’re amazing, thank you for all your work! I don’t have any Anduril lights yet (this will be my first once it’s released), so forgive me if this is already a feature now, but would it be easy to also add the ability to configure the flicker speed on candle mode? I was reading many wish for a calmer candle flicker on the original BLF LT1, and I saw starryally’s Anduril 2 fork has this but not for the LT1 series of course.
I don’t have any runtime config options for that yet. Without recompiling, it just has brightness and color mode. Changing the speed or intensity still requires source code modifications.
However, I just added a 2-color police strobe which flashes red a few times then flashes white a few times, and repeats. Because that’s exactly what everyone wants in their camping lanterns, right? 
(really, it was an obvious test to try using the new channel code at a UI level … but also, people have asked for something like that several times over the years)
As for a calmer candle mode… putting it in red mode makes it a lot less intense. Not because of the color, but because it uses a QX7138 chip for that channel… and that chip has some strange behavior. It doesn’t strictly behave according to the PWM signal it is given… instead, it takes its control signal as more of a suggestion. The MCU can tell it to go to exactly brightness level 58 of 255, and it’ll at least go in that general direction… but it stops whenever it feels like it’s close enough, and kinda makes its own decisions about if and when to move when the control signal changes. So sometimes instead of flickering like a candle, it’ll just stop and wait for a while. This quirk is also visible sometimes in bike mode and factory reset mode.
If the group buy is still open, interested!
Good news, everyone! The group-buy for the LT1S Pro is officially on! This is your chance to get this lantern for $49.99, which is $20 off the regular price! The Group-buy discount code: LT1SPROBLF The stocks are limited and once they are gone, they are gone. Click here to secure your LT1S Pro now and enjoy the benefits of this versatile and reliable lantern!
The BLF new version has a safety feature that prevents me from sending the same group-buy message to multiple people. This is to avoid spamming and abuse. I have messaged some of you individually. I have also posted the group-buy discount code here. Please let me know if you have any questions or concerns. 
I’ve got the 4 channel modes implemented, but am still working on adding thermal regulation, dynamic PWM, lower lows, and the channel config menu.
… and updating all the other lights in the repository to use the new system, including new channel modes on several other lights.
The way it works is:
These work globally, anywhere which doesn’t have those actions defined. To make it work in ramp mode, I moved the smooth/stepped ramp toggle to 6C (but it still works via 3C when only one channel mode is enabled).
The 4 LT1S Pro channel modes are:
Default for now is mode 2, auto tint. But it’s easy to change (3C while on), and the user can enable or disable each mode, to get unused modes out of the rotation.
I haven’t sent out any code yet, since a lot of internals are still in flux, but once that stabilizes a bit I’ll get the code published.
Thank you! Hope to receive mine soon!
As of this message, stocks appear to be
44 w/o battery
139 w/ battery
I just made it 43 w/o battery 
Couldn’t pass up the price. Now I have to find a proper fork.
Red LED is still 660nm?
Just purchased. Thanks for making the BLF community a priority!
