@ZozzV6,
Say, where did you get the premade a PD68 lighted tailcap board? I can find only the ones with 2 LEDs and built-in switch (from Kaidomain I think).

I couldn’t get the SRAM decay method working very well with the 85V. Things wouldn’t start to decay until about 4 or 5 seconds, making short vs long press duration checks pretty much useless. OTSM is so far the most accurate method I’ve used.

It’s certainly a pain to adjust the timing on the decay method. It’s probably just dumb luck that the components on a nanjg driver happen to give it a reasonably useful timing. With different values for any of its components it probably wouldn’t work. And then most of the BLF driver designs copied it, so the method continued working, mostly.

OTSM would definitely be more flexible and more accurate, given hardware capable of doing it.

I made myself. I think my english tricked you. I tried to say that I made the lighted board before the host arrive to just put them together when I get the host. Wink

Solved my VG10 problem today.

Looks like I got a new cree star inside Big Smile



Found some copper pieces about 0.5mm thick and stacked them up to fill missing space.
Soldered them together, put some thermal paste and it’s perfect now Thumbs Up

Finally built my f13 triple.

Used the 22mm MTN fet+7135 with guppydrive

32mm noctigon with xpl-2 v5 4k

Ledil cute-3

Dual spring bypass with 18 aug at the tail.

And a killer copper spacer from k-ru.

Wow. Topped out at 3070 lumens with a 30q.

This is my first light to break the 3k barrier for lumens

Really impressed on how it handles the heat. The spacer was a nice snug fit. Painted it with silver and the light can last almost 4-5 min before it gets too hot for me.

X7 triple is next!

Not sure if it’s modding
I replace the faulty switch of utorch ut01, it works well now, great light for 14500 battery

I need to do this too.

What kind of switch did you use? Can you please post a link where to buy.

Thanks, unfortunately I can’t order from taobao and the rest (mouser, digikey) have too high shipping costs for a sub 50 cent item.

What country do you live in? Maybe you can find a member that’s buying something from one of those places and have them buy one and ship it to you.

Have you tried looking on eBay?

Or AliExpress?
(edit) Hmm… no results there, sorry..

Looking for:

Made another Texas Avenger driver and reflo 3 Nichia leds from a Kaidomain triple to a Noctigon XP20 triple.
Before heating up. I like to see the small solder balls in the paste through microscope Smile Fun to watch them melting together.

Anyone familiar with this driver? I took it out of the TrustFire ST-80 that is running SST-50 led. Goal is to change it to one mode only but I did not expected to bi so complicated.
Other part of the driver (not shown) has 2 mosfets K3638, sense resistors and a coil on it…

Trustfire makes their own drivers AFAIK, and they usually look complicated. I hope someone can help you (I can’t)

If it's got a sense resitor and a coil it sure sounds like a buck. Tow fets sounds like a synchronous buck, which is kind of cool if that's really the case. I'd be looking for an amp attached to the sense resistor (if it's not built into the buck controller) and then some circuit biasing the amp output.  That would be the thing to hijack, the biasing circuit.  But it might not work that way.

I made two PD68 lighted tailcap board for my future builds. One will be in the Jaxman E2L triple host. The other maybe in VG10 triple.

Here I added some better/more pics, maybe someone will be able to spot solution before I release the magic smoke that lives inside the driver Smile

Interesting thing: on the eeprom chip there are 2 pins soldered together (modes were: hi-low-blinky-blinky-sos) when I removed bridge modes were: hi-mid-low-strobe-sos…

Some parts arrived from MtnE yesterday. Bought my first E-SW driver and installd it today. Seems to be some issues with the modes. Ordered it with ML+6 and there are only 5 modes after ML. There is an extra dead Off spot as I need to hit the SW 2X to get it into ML. Anyway the driver is installed and otherwise working and it’s not coming back out.

The second Solarstorm K2 has the E-SW Fet+1 driver piggybacked on the gutted original driver board. Yeah it ended up as a Triple XP-L HI V2 3C. Used a copper X6 spacer and 2 XP32 under the emitter as spacers and All stacked and soldered together.

Some pics of the driver install.

It is necessary to turn on the strobe. And with a multimeter to look for where the signal is coming from. It is necessary to find a EN signal that allows the DC-DC inverter to work.

I would suggest to add some silicone for heat transfer from the new driver to the old one.

Thanks and appreciated.
Does not work as it should so if it burns out I will make sure to fully test the replacement and thermal silicone that one.

Just put together my first S2 triple. I used dedomed XPG2 S4 2B emitters and the carclo 10507 narrow spot optic. Nice large spot; I like it. Almost twice the width of the beam of my S2+ with XPL HI and narrow TIR. With a fresh 30Q it pulls about 9.5A at start and does about 2300 lumens and 26 Kcd.

I’m going to put a rotary dial in the tail to continuously control the brightness, similar my mod here.

thanks for the advice, unfortunately I am not that good at electronic, best I was able to do is to activate one FET by connecting Gate pint to Bat + (I measured that it gets same voltage as batt.in while in HI) this give me half amperage that is usually in HI mode, second FET was disconected, but the other FET has 3.3V on Gate pin while in HI mode and that 3.3V is supplied from one of the chips (botom right) and depends from what mode is activated and when I tried powering this second FET with external supply of 3.3V it didn’t work (FET started heating up but no light from LED).

Here is my rough schematics of FETs, maybe someone will see something here but for now this is out of my capabilities…
