*BLF LT1 Lantern Project) (updated Nov,17,2020)

They are compatible, as the LT1 was designed & patterned to use the same battery tube as the Sofirn Q8. ( to save manufacturing & sale cost) only the end cap is different as it has the tripod mount threaded hole on the LT1 version.

Yeah I'm sure pogo pins are super comfortable but really, if there's no standardized pad arrangement you'll have to make a custom pin holder from scratch for every light. Kinda defeats the purpose. I wouldn't really know how anyway, and would have to buy pogo pins first etc... So I just took out the LT1 driver (easy to do, just two screws) and clipped onto the microcontroller. However that's really annoying if you are developing a firmware while also not having an external power supply. My clip constantly fell off tho so I got really close to just soldering wires to the programming pads on the driver after the 30th time flashing it or something lol. But yeah, no idea how other people do it.

Edit: You only need 6 pins for programming, the LT1 kinda has a 3x3 pad arrangement. Are you sure the Emisar kit doesn't fit mechanically onto these pads? If it does, it'd be easy to make an adapter cable that just makes sure the pinout is correct.

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.

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 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?

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……. :beer:

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).

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 ?

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

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.

only 2 new colours?

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.
