I try to make another use of the NarsilM firmware driver.
Not working properly still.
After installing the battery, direct light high, and then will not light up again.
7135 using A705NGT-350 SOT-89
Flash firmware on Attiny85

I did not show a picture from the driver with the insulator inserted
Basically the platic insulator you see on the carrier here fits inside the insulator on top of the driver the distance between spring and ground is 12.5mm, also there is no ground spring
And the distance between pisitive spring and the ground ring is 12.5mm
Aha, thanks. It’s a plastic ring on the driver side. The picture on the Banggood site showing the three parts, head, battery tube and tailcap, made me worry it might be aluminium.
Well, Lexel pointed out the LED's are 3 sets of 2S3P, so has 3 pairs of wires, 3 separate circuits. So either there's a component failure or maybe loose wire in one of the 3 sets of parts and wires.
Not a loose wire as all 3 banks work at the other 4 levels. I’d look over the driver with a magnifying glass to see if a resistor or some other part was burned or not soldered properly. I don’t know if it uses 7135 current chips, but if it did, it could be a bad one of those on the bank that doesn’t work.
Lexel - is the MF01.ZIP board a go, and tested? It looks dated August 27th on OSHPark here. I see steel_1024 used an earlier version - seemed ok, not sure.
On Lexels 4th batch page he says he can make them. One other person wanted one, but I think he was looking for at least 3 buyers for Oshpark, because he has to order 3.
No, not interested in an assembled board. Been building dozens of my own, ordered probably about 100 OSHPark boards by now since February 2014.
I've had issues on the 7135 channel on my other high amp 2S cell builds: 16X XHP50 and MT03 with 3 XHP70.2's. Not completely resolved, been getting help from DEL. Dunno if Lexel has built anything true high amps in 2S, meaning maybe 20K lumens and up.
