Pre production sample [Review] Astrolux MF-01 4x18650 flashlight supplied by Banggood

Yea, awesome. Just wonder if the std SRK size boards will fit. Might not have clearance for piggybacking in there? From your pics, looks pretty tight. Not sure if a SRK style driver would fit or be compatible as-is.

Beam shots are awesome! That thing is a search light. I’ll definitely be getting one!

I don’t know if they are comparable but would you describe this as Q8 killer?

For $20 it would be a Q8 killer . I wouldn't bury the Q8... yet. Without knowing lumens, throw and how the UI works, hard to compare. Only 4 output levels compared to smooth ramping plus multi mode sets, etc... I can also still pocket a Q8 but with the wide head on this, I don't think I could.

Plus the Q8 is a fully open source design.

Hi

I measured the driver with 47.5mm like the Q8 one

give me some time and I make one for you

How many cd it has?

This a modified version for MF-01?

yes I took the measurements in my sample and modify a SRK layout to fit
I did some minor adjustments after you quoted it

So how much do you ask for a working driver with NarsilM :slight_smile:

If it so, I would like to have its drawing/3d model.

depends how many want one
Oshpark sells always multiples of 3 boards
so if only one would want one thats 17.55$ for 3 boards

Prices:

17-22mm

Narsil v1.4
13.5$ Attiny85 with temperature calibration
14$ temperature calibrated, 1S LVP calibrated to any value you want

NarsilM Attiny85
12.5$ flashed no settings,
13.5$ with temp calibration and max temperature preset,
14$ with calibrated 1S or 2S LVP / temp calibration and max temperature preset, this version has no indicator LED

loose spring adds 0.3$

47.6mm add 5$ if 3 boards come together

LDO 1.2$ 21mm and bigger only

Bistro or Narsil customized modespacing adds 1-2$ depending how many groups you want changed
or you suply a hex add 0.5$

SRK Size with more than 8 AMC7135 Bank add 1$ for all 16 AMCs

so NarsilM without calibration
12.5$
LDO 1.2$
copper alloy spring 0.3$
5$ for bigger board if 3 drivers gets ordered
2$ shipping
1$ 16 AMCs

so minimum price is 22$

Dang, that was quick!! Wow, thanks Lexel!! Now we're cooking...

Great work, this light is getting better really fast.

How many lumens do you think the light will put out on the 7135’s?

What were the 12v cc chips you mentioned in the other thread?

What would it take to modify this board to use them?

Good flashlight, but… you know, after this story with S42’s short tube and ugly USB cover too hard to trust them…
When I think about thear QC, I am understand that this QC - is only checking if it’s posible to turn on a flashlight.
So, thank you, Asrolux, but NO, until full reviews and specs.

very interesting……

Interested in buying PCB

Are you willing to list part capacitance and resistance values?

The parts are the same as for all TA 2S drivers

MCU Attiny85 for Narsil

Use 1% resistors all around
R1 : 19.1 k (220 k for e-switch lights, 360k for 2S setups like the L6 driver)
R2 : 4.7 k (47 k for e-switch lights)
R3 : 100 k
R4 : 47 ohm
R5 : 4.7 ohm

R6 : 0 ohm jumper, or can use a solder blob (LDO drivers only)
R7 : 0 ohm jumper, or can use a solder blob (LDO drivers only)

BR : Bleeder resistor for lighted tailcaps, varies between 470-630ohm (optional)

C1 : 10 uF (be sure it is rated for the voltage you plan to use, so for a 4S setup, it needs to be 20v or more)
C2 : 0.1 uF (10uf for LDO drivers, can use the same one as the C1)
OTC : 1 uF (functions as e-switch pads for e-switch lights)

U1 : SOIC-8 footprint Attiny25 for bistro, the 20mm+ versions have pads for the Attiny85, the 25 & 45 also fit on them
U2 : LFPAK56 MOSFET (aka, “FET”). PSMN3R0-30YLDX is a popular cheap option, the SIR800DP is better but costs more.

D1 : Schottky Diode SOD-323 (if using a zener and 2S cells then you will need a 200 ohm resistor here instead)

Z: Zener diode (link is external) SOD-323 (Optional, only needed for 2S+ operation)

LDO : Designed around the MIC5235-5.0YM5 LDO voltage regulator

7135 : Standard 350ma or 380ma 7135’s can be installed on these pads. I prefer 350ma myself. You will need to clip the center pin of the top side 7135 if you plan to use a bleeder resistor. The 7135’s can be purchased from RMM or FastTech
