I wonder if Astrolux could offer us a MCPCB board with XPL-HI leds in neutral 5000k white like 3A or 3C tint at a reasonable cost… Freeme could you ask?

Even a blank MCPCB would be nice for those of us who like doing it ourselves – I’d love an MF01 MCPCB, but the only one they sell is pre-populated with 219C; would be nice if it cost half as much as it does (or less, preferably) and no emitters.

Or, basically just some kind of Astrolux/Mateminco spare parts catalogue. I’d do pretty terrible things for a few spare FT03 centering rings…

Just received my olive green 4000K version.
I like this light, decent quality, looks nice, size is good and the tint is beautiful, no green at all. Will test it later on a night hike in a wood.

Thanks FreeMe for this deal.

My olive green also arrived today - look'n real good! Yes, I got the 5000K greenies, but I like green smilecool.

Dunno, but at the low levels I guess the green is noticeable but really it's not that bad to me - I've seen worse.

Did a couple tweaks - cranked up the switch/aux LED's to high and set max ramp to the max 150 level. It's really an impressive quality light, running on a 26650 LK 5000 for now.

I ordered September 26; received October 26.

My mindset is: order from China, and forget about it. It’ll be a surprise when it finally does arrive. Party Party Party Party

Edited to correct arrival date.

Received all 5 of my lights. All tested okay. Very cool aux led functions. NOTE: when light is locked. triple clicks cycles through the aux led modes, including turning it off.

High guys, all of my MINIs have the same problem, they measure the voltage incorrectly. Is there a way of calibrating them without flashing firmware? (I cant do that)

They read freshly charged 26650 cells as 3.9V. I measeured them with two different multimeters and also under load, they are 4.2V spot on.
I put the same cells into astrolus FT03 and they were measured at 4.2V. What is happening with them? Anyone has the same problem?

I have 3 standard aluinium ones and 1 copper/1 brass on the way. Its not a complete deal breaker but it makes the voltage measurement function almost useless…

I bought them as gifts and now I find out this.

EDIT:
black one measures 3.9v
gray one measures 4.0v
sand one measures 4.1v

Couple of my results:

  • cell is 3.996V (Fluke DMM) and the MF01 mini reports 3.9V (custom NarsilM light reports 4.0V)
  • cell is 3.601V (Fluke DMM) and the MF01 mini reports 3.5V (custom NarsilM light reports 3.6V)

My custom NarsilM driver is in an Amutorch X9, but I hand calibrate the voltage readings on a driver by driver basis. I've found you need to do that to get accurate readings. Having a 0.1V or 0.2V delta difference in a factory driver does not surprise me, specially for our BLF designed drivers. There's variations are part to part, just like temp sensor variations.

If your worse light is off by 0.3V, that's also not that bad - it's accurate, just reading 0.3V low. If you tried a low voltage cell, like at 3.5V, you'd probably see 3.2V or 3.3V reported. Really not much of a difference.

(Sorry for the typo corrections...)

So there is no option to calibrate volage within Anduril menu itself (I know I cant have everything, its a fucking amazing UI). Well its just a bummer the 0.1V difference is nothing catastrophic, but 0.3-0.4V is 10%… Hmm, wish there was a calibration option in anduril, like the ability to add substract +/- 0.1V. or insert a measured 4.2V battery and have an option to set “this value you are measuring is 4.2V”.

I should go and beg ToyKeeper to add something like that into new versions of Anduril. Smile

Edit:
The only flashlights I had before with Voltage measurement function were BLF Q8 and astrolux ft03 and those happened to be bang on, the Q8 always showed the voltage of the highest cell and FT03 was very precise, it didnt now there are larger differences in other lights.

Hhmm. It's possible there's differences between NarsilM and Anduril regarding the voltage readings. I implemented the exact technique/source code that DEL wrote - it had more precision but still, I found it to need calibration. Mind you, I was a bit anal about voltage measurement - I wanted it accurate to 1/10th better than what's blinked out (0.001V).

Also the other major difference is my BLF drivers are using parts bought in the US from reputable distributors (Mouser, etc.) while these drivers are most likely sourced from parts in China -- I don't know that for a fact, but I'm assuming so. Lexel would know better. He could be providing the drivers complete, or not -- not sure.

From what I recall, the variables in the design are the MCU and the diode used for reverse polarity protection, both critical in effecting the voltage reading, and can have +/- tolerance ratings.

It might be wishfull thinking, hut I hope that I get higher quality ones from those limited editions. Or just that i’ll be luckier and get better pieces of the lot. 100$ is not really a budget light anymore.

That brings me to another quesgion, does the charging circuitry use independent voltage measurement (I think the answer is yes but I am not 100% sure)? It would be really bad if it tried to charge to battery to 0.3V more…

And not to bash the light so much, I just tried it outside in the field (night with no illumination) and I liked it really much! The beam spreads nout really nice, it has some flood and quite decent throw! The beam isnt as throwy and well defined as Q8 for example, but the MF01 MINI peerforms really nicely! It looks like a great EDC and its pocketable!! Outside the voltage measurement inaccuracies I am really happy with it!

Drivers will be the same regardless. Believe it or not the brass and copper lights are still cheap - easy $200-$500 I would expect from other sources.

Pretty sure the charging circuit is independent of the MCU monitored voltage. Funny - the typical chargers (NiteCore, etc.) are spec'd to +/- 0.05V, which to me is not very accurate. 4.15V is acceptable as a full charge, and by the time you get the cells off the charger, that level could be dropped even further. That's why I love the SkyRC MC3000 chargers - I got two, both set to 4.22V for full charge, and usually is dead-on.

It's a great power pocket light, and love the look, SS bezel, button feels about right. My smaller X9 though kills it in output with 3 XHP50.2 3V LED's. I'd still like to swap in LED's with more power, like the 351D's. Want to check if they fit in the optics, then tweak up the springs and LED wires, FET, etc.

Noob question regarding the trimmers, I see four of them on the light, am I correct in assuming they all change the brightness of the aux leds? If so, why are there four of them when I see only three different colors? Thanks.

I would ask here maybe: http://budgetlightforum.com/node/61921

Lexel is the AUX LED board designer, and sells board for lights that didn't come with one.

Possible he has one overall brightness level, then each of 3 levels can be tweaked. Or, one pot is for calibrating the LVP feature? Maybe? Dunno...

From op:
3.9v-4.2v: Green, d1, d2 on
3.3v-3.9v: d1, d2 on
2.9v-3.3v: Red on
<2.9v: All shut down with LVP
Using 4 trimmers to adjust the brightness of AUX LED.

One trimmer per color. There are 4 colors. Each trimmer has the letter next to the matching led color. Like Chatika vas Paus posted:
Low is red
High is green
D1 is blue
D2 is Pink

Ahh, ok - I took off the bezel and optics on mine and see the 4 different colors. RED is only lit if it's at low voltage.

In order from outer to inner:

  1. GREEN (high)
  2. BLUE (D1)
  3. PINK (D2)
  4. RED (Low)

Weird labeling but it works!

Received mine yesterday. Green, 5K. Yes it’s a little green in low levels, but not such disturbing in real life (I walked for half an hour yesterday night in the wet fields around the house…) exept in front of an absolutely white wall…
Nice quality, flawless…
Very nice little light, with too many abilities as it is…
The faster hand warmer I have !!!!!
Thanks freeme, it was an absolutely well worthing waiting…

I received mine (Gun Metal/4000K) on Monday, had a bit of time playing with it and am impressed.

I think the aux leds are a bit busy-looking, but because they serve a function, I’m not bothered. I’ll try tweaking them this weekend.

I’m not a big fan of on-board charging mainly because of the way a rubber cover can let in dirt or moisture. I’ll most likely keep this light away from the harsher elements and use it around the house and property. For backpacking, I’ll use a lighter and smaller light anyway.

It fits my hand nicely and is fine for a jacket pocket. No sharp edges or flaws anywhere. I gave up some lumens to have a warmer tint and I like the tint a lot. It’s still a powerful package and a nice mix of flood and throw. I’ll bet they’ll sell a heap of them.

I had to fish around with my tools to find a small enough screwdriver, but I had no problem adjusting the trimmers once I did. I turned down everything except green and it looks less busy now.

I used the light for a while tonight and I am glad I made the purchase. I was going to hold off on the first run but I see no issues with this light.

I also like the way it can use a 26650, 18650 and 21700 cell. Nice job Astrolux. I’m using a Shockli and I doubt I’ll use anything else, unless some sort of extended use situation comes up. Nice though for folks to have choices.

Anyone else pulled the driver yet? I’m assuming it’s de-solder the AUX and emitters; there didn’t seem to be enough give to bring the board out enough to get at the MCU.

Will also do a reflow at some stage with new emitters Smile

Yes, just a couple pages back. You undo 5 wires. http://budgetlightforum.com/comment/1574955#comment-1574955

Thanks Freeme! Ordered two more in tan and gray! My green one showed up today and everything if functioning great! My new favorite light. I just got my Acebeam X45 two days ago and its a great flashlight but this MF01 mini is amazing! I love the UI! Ordered three diffuser as well.

Thanks for the info above on the trimmers. I have one last question before I adjust them. To increase the brightness of the aux leds, do I need to turn clockwise or counter clockwise? Maybe the light is more durable than I’m taking it for.. I’m just worried I might break it!

The trimmers will move quite easily – you’ll know if it hits a stop. That said, some will spin continuously, but will go from 100% to 0% in a tiny turn(like hitting 12:00 on a watch).

Clockwise increases brightness, from memory.
