One of the microcircuits sets the modes. I therefore suggested using a strobe. A repeating signal is easier to find with a multimeter.
Those. You have a microcontroller. It sets the operating modes of the inverter.
Modes are low, medium, high. They can be specified via PWM. Or by connecting in the feedback circuit of additional resistors with the help of FET transistors.
If you can find which one of the microcontroller’s feet produces a signal the SOS or strobe. Then you can apply the required voltage instead of the microcontroller (for example, 3.5V).
It should be just a EN signal allowing the operation of the DC-DC converter
I hope I wrote correctly … English is not my native language Smile

i change the emitter of nitecore EC4 to xpl-hi, change the MCPCB to DTP, mod the thermal resistor
too bad, the led was out of center, i may have to reuse the stock mcpcb
some interesting things i found
the driver uses STM32f0 32 bit micro controller, which is quite impressive to me( much more power than attiny 85, or any other 8 Pin Uc)
the driver when open connect has Vbat voltage on the output( which mean i can mod the XM-l2 to XHP50, or even xhp70, whatever you want)

Forgot my pen

Interesting. I was just looking at those a few days ago, wondering if they would work in flashlights. It would certainly increase processing power and onboard capabilities, at least, going from 8-bit MCUs to 32-bit. Not that we generally need more processing power, but IIRC it has a bigger instruction set than attiny, which could make some things easier. Like, if it has a usable divide instruction or floating-point, some things could be calculated onboard instead of being precalculated into tables.

This is what I’ve been doing in for the past few days. The mod will have two xpg3 cri 5700 and two nichia 219c 4500 cri. It will be powered by a one of a kind driver. An upgraded version of one of the best three channel drivers available with full thermal regulation. Can you guess what driver?

I don’t find much time to sneak mods in but today I found a few minutes to do this quick & dirty emitter swap on a Thorfire KL02. Even essentially serving as a spare battery holder I found it’s CW tint too harsh. I swapped in a Nichia 119A (3,500k I think?)

Given my time crunch along w/ the fact that my heatgun & dremel cutoff discs are all loaned out I didn’t fashion a good heat path for it. I had initially thought to put in a dual emitter in the light. However I ended up just going into my parts bin & grabbing an emitter pulled from somewhere. As the stock emitter has it’s anode & cathode similar to a luxeon I or III -> it took a little finagling to fit a Nichia 119A in it.

Given that this light will just serve as a battery carrier for me I’m not all that certain that I will spend anymore time on this light.

Here’s a god awful pic (I see that now. Sorry. But take my word for it. It’s tint is very pleasing to the eye.)

Well since I blew the XHP50.2 in the 47’s Ti AA, I installed an MT-G2 instead LOL

ok heres a noob question with the spring bypass is it because of poor contact or an electrical field problem with the coil .

I ask because I am seriously thinking of doing a hi power mod on a c8 just for wow factor I realise that heat will be a problem .

cheers D

Spring steal has resistance in it and will cause heat and voltage sag in high power mods:)

thanks it makes sense now so is it worth doing on stock lights like c8s L2 and the like .

I was going to change the driver and the emitter in a Thorfire C8S, but ended up with only swapping the emitter to a XP-L HI because they changed the driver to 20mm in the version I got Ughh

EDIT :

I was going to put a BLF X5/X6 in it , but the driver size put an end to that plan.

Here is the new plan : 20 mm boost driver from KD and a XHP50.2 :

Yup, I accidentally scratched it up with the burr from drilling out the hole so had to take off the coating with 0000 wool Blushing

Does this mean you can swap to a 6v emitter without driver modification/swap ?

Today I taught a flashlight how to see. It turns out that LEDs can be used to sense light if you run them in reverse. So, all I had to do was solder on an “optic nerve” between its brain and its eye (MCU pin3 to LED-), tell it how to distinguish bright and dark signals (auto-calibrate), and then teach it something like Morse code.

The upshot of this is that you can configure it by pointing it at a phone or computer screen and playing an animated GIF or something for it to watch. (eventually, haven’t written the app yet)

… and the compiled code for it is shorter than the text of this post.

I’m not really sure yet if it’s actually a useful feature or just a silly gimmick, but it was fun to make.

BLF should start protecting the IP we are generating here and file patents! Unbelievable amounts of progress we are achieving here, seeing flashlights, apps or screens to program lights, … before you know you can talk to flashlights directly.

So proud to be part of this community.

Patents for what, a flashlight?
Pretty sure that was patented a loooong time ago, lol.

I am sure many of the technical solutions discussed and developed in various threads on here are 1) new and 2) not patented yet. The amount of innovation and curiosity here is mind-blowing.
i.e. “data exchange for contactless programming of flashlights via a light-emitting diode”

I didn’t do a patent search on these things but I do have access to various content providers at work.

This is very very cool, I saw this few months back in some youtube video, good chance it was on a shot show, they made software for pc where you set all preferences (modes) etc and then point the flashlight at dedidated part of the screen, it blinks out (black/white) “settings” and thats all you have to do to get custom modes.
I just hope this could be done with so widespread Atmel Tiny13A mcu.

Well technically it will be either brighter or more effitient with a spring bypass but the difference probably wouldn’t be noticeable. That said, I bypass springs in all lights that run 2amps or higher.

Patents? Hah. I suspect the patents for this have already expired. It’s not new.

There’s a Lux-RC driver which does it, though IIRC it uses a dedicated light sensor instead of the LED. It’s used in the super-expensive BOSS light. And for some reason, it has a ridiculous limitation of only 4 modes. At that point, why bother? I know someone who has one, and he wishes it was more like his Convoy triple.

What’s actually new or different is:

  • It’s open-source.
  • It can work in any host without changes. Just make sure the driver has an “optic nerve”.
  • It runs on low-end MCUs like the tiny25 (sorry, doesn’t fit on tiny13).

I only have an early prototype so far, a proof of concept. All it does at this point is calibrate itself then read a list of modes to configure a mode group. It’s pretty janky. Don’t expect anything stable for a while.

I’m using an old BLF X5 prototype for testing (bistro tiny25 driver), totally stock except for the firmware and a small wire I added. Hopefully there will eventually be drivers which include this connection by default instead of requiring an extra wire. Otherwise though, it’s a totally normal build. Cheap stock host, normal MCPCB, only two wires going between the driver and LED(s). It likely wouldn’t work with multiple cells in series, and it shouldn’t work on UV or infrared lights, but those are really about the only restrictions.

One other thing to note… While all this complex onboard-programming stuff is fun and fancy, it’s not necessarily an upgrade compared to something simple and straightforward. I think Crescendo (ramping UI for clickies) is probably better overall, precisely because it’s so simple. And Narsil’s ramping UI is better still. Why bother with a dozen buttons and levers when you can do everything with a single knob?

1) you’d be surprised at how much stuff you think is original and new has actually been patented already

2) I would suggest you do some research into how stuff gets patented. It requires money, lawyers, and a lot of time. It’s not just “I made this, plz patent”. Also a lot of stuff cannot be patented because it does not fit the requirements.

The only real risk is if a corporation took it and didn’t give anything back… Fortunately, the GPL is pretty good at dealing with that. And publication of open code is good at invalidating bogus patents filed after-the-fact. Sure, there will be people who sell it for profit without contributing, but everyone is free to do that. And if anyone does make improvements, they have to share those improvements with everyone.

Would be nice if playing on BLF allowed us all to pay the rent, but that’s highly unlikely. At least it’s entertaining.

That is way cool Toykeeper! Will be following this! Not for me btw, low-med-high no memory does not require much app-programming. But it sounds like a really fun developement!

I finished the Convoy C8 with Texas Avenger driver and XP-L2 led, AR coated lens and OP reflector. It is astonishing. In turbo it draws 9,3A and with OP reflector I really like the beam too. The Kaidomain DTP led base need a little filing because if you tighten the screws to head, it blocks almost the wire holes in shelf. The Bleeder resistor needs a little fine tuning because of short and medium taps timing take too long. Sorry for the beamshots. All pics created with phone.
