New Convoy C8 – Clearly better

Only thing that C8 needs now is remote pressure switch and we can actually use it for hunting :smiley:

It should, actually. FET drivers just crowbar the battery across the LED with minimal resistance, measured in milliohms (mΩ), so the voltage they’d drop would be negligible (Vf ~ Vb), vs 7135s which drop the difference between Vf of the LED at that current and the battery voltage, or about 0.1V (100mV) minimum. So 4.2V from a fresh cell and 3.6V Vf is a 600mV difference (vs much less with the FET).

Drive a red XP-E (~2V) with 7135s, and they’ll all join hands and limit current by soaking up all that excess voltage and burning it off as heat. Crowbar the battery directly across it with a DD FET driver, and the poor XP-E will die a horrible fiery death.

Mmm, I saw from the pix it’s (thankfully) not a mirror-finish. Nice…

Flashlight-porn… :smiley:

“unistro”? :smiley:

“mini-stro-ni”? (Okay, booooo…)

Finger buffet?
Snack bar?

If it can be easily added, why not make it a option. $1 extra for cut out slit tail cap. I think it would do well. For those that have tried cut out slit tail caps, you won’t go back to regular ones.
No matter how recessed the switch is, you should still be able to turn on with gloves. But the cut outs just make it so much more comfortable and easier.

fuses are low: 0x75, high: 0xFF

Huge thanks to the team that made this light and this firmware happen! Just flashed a S2+ with the mini-bistro and it is pretty much the most amazing piece of software I have seen on this light. Works out of the box on the S2+ with RMM’s Moonlight Special v3 driver and 4x 7135 (380mA).

I used the following fuses:

sudo avrdude -p t13 -c usbasp -Uflash:w:bistro-mini.hex:a -Ulfuse:w:0x75:m -Uhfuse:w:0xFF:m

works.

I liked modes. I made myself a driver and it is very easy to configure.
Driver wonderful.

Your efforts and achievements are amazing TK. Nice work and thanks. :slight_smile:

Nice UI!

I have EDC-ed a triple with the intl-outdoor RGBW driver for a while, which has the same ‘long press goes to first setting of the mode group’ and I can tell that is a very pleasant feature. That RGBW driver has some annoying blinkies at the end of the mode group but in actual use they are not annoying at all because you never have to go through them.

Noob question: could standard Nanjg 105c/105d driver be used to independently run only some of it’s 7135 chips (with appropriate firmware)? If not, how much of a change is required to add this support, considering these drivers are produced specifically for Convoy, as J-Dub74 said?

No. All AMC7135 is parallel.

Available to order now :slight_smile:

But in the link you provided, this support is added with only two wires? Who whoever produces these driver boards, could add this support very easily in a new board revision?

The fuse settings are in bin/flash.sh in the repository:

avrdude -c usbasp -p t13 -u -Uflash:w:$FIRMWARE -Ulfuse:w:0x75:m -Uhfuse:w:0xFF:m

The stock nanjg drivers do not have the 7135 chips split into groups; there is only one power channel. So, that’s what the firmware uses. The code is written to match the hardware, and the hardware could not be modified for this project.


After trying both, I actually prefer tailcaps without the finger cutouts. They tailstand better and I don’t have to care which way the light is rotated.


It’ll work, but it doesn’t use the extra power channel on the moonlight special. If you have 4x7135 total, it’ll only use 3x7135. You might want to look at the blf-a6 firmware for something which uses both power channels, or blf-a6/tk-otc.c or blf-a6/cypreus2/, or whichever flavor of STAR suits your needs. Or you could modify bistro-mini to add 2-channel support back to it, but it’ll use more space and there’s literally no space left by default so that means removing something else to make room.

You may also want to recalibrate the voltage values, since I don’t think RMM’s drivers match the nanjg drivers exactly. And you could probably make moon run faster (8 kHz) too, since RMM uses higher-quality 7135 chips.


Okay, I get it. Asking for name input was probably a bad idea. :slight_smile:

If nobody has any major objections, I kinda like “biscuit”.

I knew I should stay away from this forum.
Now I have gone and ordered two new clear Convoy C8s and 1 clear L6.

Some people never learn. :smiley:

look at this How To Build a Flashlight With Perfect Modes (picture heavy) - #834 by Serp

Spot on, Toykeeper and thank you. The tail cap reads 1.13A (3x7135 instead of 4). I will just solder off the last AMC chip and keep this light as it is. Your software is just too amazing!

Will have a look whether I will adapt it for multi-channel drivers as 3x 7135 is bright enough for my simple EDC lights.
