You only need the six pads in the 2x3 array as labeled. Use some jumper wires to match the wiring between the programmer and the cable.

I do plan on using the usb part, just nedd a different cable/pin holder.

You'd be able to use the pogo pins as well, there's a pin header on that side as well after all. Just need to manufacture a cable that swaps signals according to the needed pad arrangement.

I'd expect six just loosely held wires to be a quite dodgy connection.

I’d expect six just loosely held wires to be a quite dodgy connection.

I meant using both sides – the programmer and the pogo pin PCB – and connect them with jumper wires. Or is Hank’s pogo pin adapter just 2+4 instead of “full” 4+4? In that case it can still be used – just omit ground or V+ and connect it directly to the flashlight.

Oh lol, sorry for the misunderstanding. Yeah that'd certainly work

Everything should be labeled. Here is a photo of the latest revision: https://i.redd.it/bzi7l3tlaui51.jpg

It is

RST V+ GND
SCK MISO MOSI

Does anyone have a rough estimate as to how long moonlight will last with 4x 3300mAh cells?

[SammysHP]

5x AMC7135: 5 * 0.35 A = 1.75 A
1/256 duty cycle: 1.75 A / 256 = 6.8 mA
LED + MCU: 6.8 mA + 2 mA = 8.8 mA
Battery capacity: 4 * 3300 mAh = 13.2 Ah
Estimated runtime: 13.2 Ah / 8.8 mA = 1500 h = 62.5 d

Probably much less due to other losses.

I appreciate it, many thanks

I know this wasn’t your question but thought it may also be useful…….

@Coscar

I enjoy candle mode. I did a runtime test in low candle mode starting with 30Qs@ 4.2v. After 21days - 24/7(total of 504 hours) the onboard voltage reported 3.4v.

Havent flashed my original version yet but realized I lost the usb rubber cover for the charge port , any ideas? I didn’t see parts listed anywher e.

Recently I got my BLF LT1 and it has a spare USB cover together with the spare o-rings. You should ask Sofirn if they can send you one. They should have it available as a spare part.

Do you know which screws (with which dimensions) to buy and that would fit the BLT L1 screw holes ?

I ordered these ones (flavor “LS047” / screw 4.5mm + additional height 3mm), and sadly they don’t fit well (and not in the same way between hole on the side versus at the bottom = it goes deeper on the side) (and i haven’t been able to find models without the “gap” in the middle).

[derfyled]

Never tried but I’m 99.99% sure these would fit.

You simply need standard photography tripod screws. Nominal size is 1/4-20

PS: ces vis sont disponibles au sur Amazon Canada, j’imagine qu’elles le sont également sur Amazon France ?

Is there anyone willing to try my custom 16 bit build of Anduril 2 for the LT1? I’d love to get some feedback on it.

It provides nice and smooth tint ramping and much less tint flickering when dimming at low modes, it’s just that the brightness curve is somehow bumpy and I haven’t figured out why yet (I actually suspect hardware non-linearities). I haven’t seen anyone else do this yet (faking 16 bit on an 8 bit capable MCU).

I can provide a zip with the source code and hex file to anyone interested (I still don’t understand how to add my code to TK’s firmware repository without considerable effort).

Sure, I’d like to give it a try! How bad is the bumpiness?

[Lux-Perpetua]

Barry kindly sent me some real pictures of the new LT1 colors. I think their anodizing team did a pretty good job, didn't they? Maybe we get to see these new colors packed with new features like full USB-C compatibility (PD charging) as well as reverse-charging, i.e. to use LT1 as a powerbank to recharge external devices.

[lionheart_2281]

only 2 new colours?

[Rexlion]

I really like that dark green. The other one just looks black on my monitor; how would you describe the color, Lux?

Looking good! - My apologies for my limited correspondence over the last number of months, been crazy busy with the big move, settling in a new house, all that. I hope to chat more with Barry soon on the colors versions, accessories, and the Mini LT1 once i get back on my feet.

[AguassissiM]

So where do I sign up for the green one and how soon can I get it?

@lionheart_2281

I assume they’re just using what they’re familiar with. These look like the EC01/3 colours
