Haikelite mt03 mods? Update!

https://www.dropbox.com/sc/5vqxezgtgrzeyoe/AAAenrAwpmNdJ2EYk3bmp_ZQaThis my second nw mt-03,this one broke, only 2 leds turn on!

looks like an LEDA 1624

Try and solder a bridge across the broken leg? Use a piece of wire then solder on top of that?

you mean a bridgebon the board?
Maybe easier to just solder it to some wires to lift it up a bit. The pins like to stick together with solder!

Too broken, chip can’t be soldered, I got some other similar looking ones, but might be other functions!

Yea try that.

If its only only one leg of the FET you may be able to use it still and make a connection with solder and wire.

no chance to get it fixed!

Looks like it will get a new driver or 3 in parallel.

Oh well. leave it for a while maybe you will think of a idea.

Yeah, Still got the cw mt-03.That one has the res mods. So I will take so pics of it tonight outside?

Yea mate if you can.
It must be massive out put.
If your going to scrap the other driver practice on it. see what you can get out of the driver?

Yeah might try dd on that one!

Yea might as well if its broken. see what you can get out of it driver before it melts lol. Even bridge the resistors with solder and see how that goes.

Great to hear about your successful resister mod. Sorry to hear about the other light getting damage. Hopefully, you can just replace the broken FET.

Chances are you have maxed out the driver with the 2 extra R100's per channel. Once the lower modes start getting brighter, it's a sign that the inductors may be saturated and even PWM cann't tame down output. You really need to measure current at each Mode before and after every sense-resister change. That way you can tell when you have gone as far as you can go and still have reasonable lower modes. Best why to measure current on a buck driver is at the emitter. So it's best to have driver out of the light so that you can tap into one of the LED leads to measure current.

You sure are not afraid to get in there and change things. Best wishes on your upcoming mods. :)

EDIT: fixed a couple typos.

It no longer powers on now. This really sucks! I tested the leds and they still work, which leads me to belive the driver is fried, I’m really pissed now.
I planned on running individual drivers to each led anyways, but now the stock driver won’t work!

When you start experimenting you must always have that in mind :slight_smile:

check out TAs drivers
Narsil or Bistro in a light like this seems really sweet!

It was a faulty switch, had a spare one and it now works again.
Seems like the electronic switch can’t handle the current? And the modes work a bit funny sometimes, but otherwise it seems fine.

For e-switch you have to go with Narsil / Tk’s ramping or some other firmware .

Modded one Utorch UT02 with a fet driver and xp-l hi v3 (driver : TA’s boards with LDO support and Narsil) .
Here are my comments : [Ended]Groupbuy : Utorch UT02 (single cell XHP-35 HI / 26650 thrower) - #503 by giorgoskok

I will be installing one to my mt03 soon …

Some pics at night with the mt-03, quite bad pics, but still!

Mode 1-5!
