✌ FREEME - ASTROLUX MF01S 15000lm Flashlight Group Buy - ENDED

Interestede, depending on price

Yes, this is the light that was having issues, I was under strict instructions to not post anything about it, although I offered to explain it in a PM to you if it would of helped.

Ok, I stand corrected on the bug, in my defense you never gave much information on it other then to say you know about the bug :wink:

Far as the possible issues.

1: I have tried it both with the temperature calibration and without, same results. Although I am still lost as to how the temperature offset could effect the workings of the thermal system as a whole, seems like it would just offset the thermal control points.

2: I ran another test yesterday with thermal pads on the MCU giving it an almost direct connection to the body of the light and got the same results. It would of also wicked away any heat from the driver, although that is minimal.

3: The driver is the same basic layout I have been using for awhile, DEL helped me get it right so it is very stable. I also tried anduril on some other lights like the MT09R and it also overheated, just took longer since it has more surface area.

4: I have tried using the pre-made hex file from your repo for the D4S / D4 and got the same results with them as well. I also tried the changes you suggested to the code with no real change except slowing the process down. Overall the only things I changed in the code was added the new layout files, which were basically just copied D4S since they use the same pinout then changing the ramp for the higher output.

The thermal control works fine at first, it ramps down nicely and looks like it will maintain the set temp at first but then it just keeps ramping the power back up even when WELL over the thermal set point using the self reported blink out.

This is what has boggled me, why does it keep ramping the power up even when it knows the temperature is 100c via the blink out? It seems like it should lock it to the lowest output once the temperature is above the set point. If it would just lock it to the lowest mode when above the set point, or say ~10-20% above it, it would be fine.

I have tried this with thermal pads already, it actually seemed to make the problem worse as it overheated even faster then normal. Yes they are a bit higher thermal resistance then metal but still plenty to eliminate heat from the driver itself interfering with anything.

Although I doubt that is an issue since the self reported temperature from the firmware is within ~2-5c of the real temperature, and it is usually 2-5c lower then the real temp, not higher.

Indeed, the shelf is a lot thicker this time around.

To this thermal pad thing:
I tried silicone thermal pad with Andúril in my D1 long time ago. Here is the thread about the results.

Maybe there is time to step up with another atmel with more I/O pins and use external NTC placed on the MCPCB like on led4power led stars.

That’s a really interesting test, especially with the thermal pads involved. I wonder how it would behave with newer code, because it has changed a lot since then.

The Samsung INR18650-30Qx2 I have been ordering through BLF Banggood offer (page20) says flat top unprotected but the BG page says protected but the length are short, so that is just a fault right?

BG page

30q are not protected, i guess wrong yea…

You can buy protected 30Q if you want to, but this particular ad just seems mislabeled.

Interested, hopefully orange or clear.

I’m pretty excited about this one, great grouping of features with the AUX LED and Anduril. I think the SST20 should manage to output a very postive runtime.

I’m not concerned that the MF01S isn’t the brightest or smallest soda can on the block. I already own an Acebeam X80 with 12x CREE XHP50.2,2x CREE XPE2-R2 630nm, 2x CREE XPE2-B4 475nm, 2x CREE XPE2-G3 530nm, 1x Nichia 233A 365nm. I’ve also got 4 ROT66 with SST-20, XPL-HI, and 219b emitter groups. IMO it’s really about features in this classification.

Interested.
