Thanks for the nice replies! I guess I got lucky on quite a few stages in this mod…
@ReManG these blocks aren’t just blocks offcourse. It’s a real high-tech Dutch soldering system :laughing:
I was actually thinking I really need clamps next time. One shiver and all plumets to the ground…
Won’t you easily move the leds with a qtip and risk shorting them out?
The reading on “off” gave 0,025A. So a bit more than sub-lumen I guess. Guess that drains the battery in 5 days. While I wasn’t planning carrying this thermal granade without lockout anyway , I still hope someone has an idea why it’s not turning off…
Maybe a ground problem? Or the “1” level I programmed the firmware is too low and gives errors? I need to redo the “high” anyway, since 40% is still thermally unstable. Will try 30% next time.
@Giorgioskok the microswitch connects to ground (outer ring on driver) and Attiny13A pin #2. This is the “switch” pin in the firmware from Tom E which I flashed to the BLF driver. I soldered it with 22AWG wire, but I guess thinner wire would be easier.
