I’m just now seeing this thread. Sorry.

Texas_Ace already built a GT with the 70.2.

I seem to recall he upped the amperage to around 8A (12v). He was getting over 7000 lumens and I think 1600 meters.

I am not familiar with the black flat. Too small and weak for my needs.

OBF should get close to 2Mcd

If using normal CRI70 70.2 I estimate 650kcd with 12V 6A Buck driver possible to go to 7A, over 7A the sustained lumens do not increase much

I should get this week new boards for a far more efficient MOSFET than the old

at those currents it is critical to bridge the carrier springs

The battery springs are from Copper alloy
but idnk why the carrier button spring is not, definately likes a magnet and has pretty high voltage drop

lexel, I finally got around to installing your GT driver in the XHP35 MT09R and WOW! It was only “decent” before but now serious. Stock led, smooth ramp 80% NarsilM v1.2. Got a little chirp on contact charge but good now. I took your suggestion and did not bypass the springs. Great driver! Keep up the super work!!

New generation of drivers releases now

replacing the at 2S unreliable AMC7135s
DD + small FET and resistors instead

MT03/09R XHP70.2
support of permanent switch LED plus MCU indicator with resistors


30mm for Convoy L6/ Thorfire S70S
support of permanent switch LED plus MCU indicator with resistors


20-22mm with 2 FETs and also 6+1 AMC

here with 1S configuration with 6+1 AMC
I had to drill out one via on the spring side partially that secures the switch pad from lifting if soldered too hot

17mm 2S with 2 FETs


17mm LX v1.0 FET+5+1
more filtering caps for very high drain builds

No AMC ? DO you use PWM on the FET to get lower modes ?

Not sure where the best place to ask this is, so I’ll give it a try here. I had some boards made using: your ‘new’ 17mm TA layout. I built one in a 1s configuration with an ATTiny25v with no LDO, Zener or bleed resistor using recommended components and resistor values.

I flashed it with the bistro-TAv1-OTSM-HD-attiny25.hex file provided in the Bistro-HD v1.7.1 distribution.

It works great, except for one thing. The voltage readout is wrong. It usually reads out 4.2. I may have seen it go as low as 4.1.

My understanding is that the firmware I am using reads the voltage from Vcc. So I am really at a loss as to what could be wrong. My understanding is that 1.7.1 is pretty well tested for OSTM configs, but should I be using v1.4.1instead?

Thx.

It depends on the voltage drop on the diode, there is also some variation from MCU to another
voltage readout can be off 0.1V this is normal

Hi.
How can I buy those drivers?
I am interested in 17 and 20mm boost drivers. Is it works with low current buttons?

I don’t think he is selling the boost drivers yet.

Here is the thread that you can order from.

My Convoy L6 thread with XHP70.2, Texas Avenger FET driver, Narsil v1.2 ramping firmware (old), lighted side switch and cut down SMO reflector. Lots of amp draws on stock driver as well. 

My Supfire L5-S thread with XHP70.2, 26350 cells (4,100 lumen!), Texas Avenger FET driver, NarsilM v1.0 ramping firmware and lighted side switch. My mini L6!

Thanks. I should have been more clear though.

The problem is that it doesn’t just reads out 4.2v with a charged cell. It reads out 4.2v even when the cell’s resting voltage is closer to 3.7v.

I also realize I have no idea what value caps to use for C4 & C5 on the larger boards.

I got no idea what could cause this, I had never voltage readout making problems, sometimes the diode bridge was closed by solder paste and I got 4.4V readout

Thanks. I’ll have to refer to the schematics to better understand the extra caps.

I wonder if I bypassed the diode by mistake somehow. I cant remember how low I took the actual cell voltage. I know I haven’t tested it with low SoC cell, but I thought I’d check with a cell @ ~3.7.

Any chance you might come out with a driver for the HaikeLite SC26?

That uses a boost driver, yes? I think he should be selling them soon, but not at the moment.

Yes I believe it’s a boost driver. 28mm if I recall correctly.

Lexel, any hint as to what you may come up with for a SC26 replacement?

I got atm not enough time to get ahead with the Boost, I made some progress just to run into a problem again
I ordered version 3 of prototyp boards 10 days ago, with enhanced thermal path to cool the MPS chip as I ran likely on 50W output into thermal problems I hope the new board will fix it

new 2S version without AMC for more realibility, also added 2 switch LED support

46mm 2S/2P MT03

new enhanced version no more AMC7135

3 step filtering to get the rininging from PWM under control

.

Buck drivers:

20mm and 22mm
4 layer for better thermal properties

new more efficient MOSFET and minor changes

23mm for Klarus XT11/12GT running 2 18350s for Oslon BF or other 3V LED

30mm cheaper but bigger inductor

new with L6 compatible Ground ring and new MOSFET

42mm TN42

new version up to 8A also for TN40S mods with XHP35s

46 mm MT07/MT07S

new version a lot more efficient MOSFET

47,5mm MF02

new with better MOSFET and a lot imptrovements

46/47,5mm 2S/2P or 4S/1P AstroluxMF01/ Haike LiteMT03
MF01 v2 in 3S/6P LED Board mod, driver has 4S input 3S Output

MF01 v2 3S 14A dual Buck driver with new MOSFET and now single sided

BLF GigaThrower driver
XHP70.2 or Oslon Black Flat up to 8A

new version

also made a programming adapter for my future drivers
same order in 2 Oz from Oshpark that gives 0.8mm thickness

Order from OSH Park

Fits those pogo pins from banggood

So I think final version of programming port found

rearranged pins to fit MCU pins arrangement better than original v1.0 had

improvement machanically
2 traces on the pogo pin board to self align it by the solder
increased pad size on drivers to 0.8mm, to compensate wrong pogo pins
length of the solder traces on board reduced as some flux went in the pogo top, can be solved with alcohol but more distance is better
Added a key head for easier handling
added 2 holes to use a wire strap to secure the programming wire

Picture of v1.1 on V1.0 board, pin alignment does not work on the small 0.6mm pad on first reflow

You have quite a collection of drivers already! So, how many of these existing drivers will be updated to use the programming key?

Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone.

over time new ones, but I have here hundreds of old boards stocked up, likely 600-800
so if I take a new board over an old I would charge something, as I am usually try to use older designs if the performance is the same

If a board got new MOSFET like on the Buck I am sitting on dead boards and parts if noone want a XHP35 Buck driver, where old parts have no disadvantage
I even cancelled the current enhancement fee for high power parts, but those 6-8A all get all new parts

When you say “LX driver” are you taking Texas_Ace’s design, tweaking it and calling it by your new name?

I’m a little confused on this.
