It looks like everything is pointing to a bad 7135 chip, specifically the single chip on the lowest channel.
So the stuff under 120 lumen is all going through that single chip. Above that level, that channel goes 100% and the next channel, 7x7135 chips are PWM so itās still using that first 7135 chip but itās effects become less noticable. Then on Turbo itās the FET only.
A new driver should fix it, but if your not able to solder the 2 led wires, a new head would be the fix.
If you have hot air you could try swapping in a new 7135 chip, but itās a bit more advanced.
A work around would be to anodize the threads part way . Leave 1/8 inch or so bare . One turn probably would physically lock it out then. With all the D4V2 talk about lock out got me thinking.
I received my FW3A with XPL HI 3D yesterday. I was pleasantly surprised that the torch seemed more robust than I expected. The switch doesnāt appear to have any of the metal-scraping that others have complained about in other posts. This was my first venture into the Anduril UI but it is much more intuitive when you are actually doing it than reading about it.
One question - when using the smooth ramping to go up or down in the brightness scale there seems to be a āhitchā halfway in the run. In other words, as I go from dim to bright or bright to dim, about halfway through it blinks out then back in. Is this normal?
A couple weeks back Neal had sent me a message saying he was going to replace the shorted one i had failed, i never heard back since, and he ignored my direct message i sent to him last week.
If you set the ramping to go all the way to Turbo, you will notice a short blink as it ramps up to the top of the single 7135 channel. This is about 125-130 lumens on the 3D light. Then you will see another blink at the top of the 7 x 7135 channel. This is about 950-1000 lumens on the 3D light. Since the stock ramping level tops out at the 7 x 7135 level, you only see the single blink as you ramp up and down.
Toykeeper added these blinks at the request of the BLF members.
What are the chances that I could order a new driver for one of my FW3A lights? Iām pretty sure I messed mine up trying to flash the new Andruil firmware. Iāve already sent Neal that question and waiting for a response.
Iāve been trying to get it to communicate with my computer and it canāt find it. The other driverās Iāve flashed communicate just fine.
I wonder if someone could sell just a programmed MCU? Thatās all you really need. Just swap that one $1.35 ATtiny85 instead of a much more expensive driver.
JasonWW, If I were to buy some ATtiny85 chips, in theory, I should be able to flash them and then replace the one on my driver, right?
contactcr, I donāt think I had any interference but Iāll double check.
Neal contacted me and Iām going to buy a few drivers to fix my light and for emergencies. But in the meantime, I have nothing to lose experimenting with the one I have.
Is there a reset to factory default? Some how Iāve changed the ramp ceiling so it now ramps to max instead of lower ceiling and double click for turbo
