Zoomie’s usually have screwed down mcpcb and/or a threaded shroud over the pill that presses on the centering ring/mcpcb. These things serve the same purpose as bezel pressing down on reflector/mcpcb.
Fair, I forgot to take photos for a lot of the process.
It’s a sst-20-dr 660nm because it’s what I could get with 1 day shipping from digikey. The footprint of the sst-20-dr seems to be only available in the B120 version which isn’t our usual 3535 footprint but has smaller pads. I only noticed after the LED wasn’t bouncing during the reflow like the other sst-20s. It’s not an issue with just the 350mA from the 1X7135 that’s powering it.
I cut the traces from the bank of 7135s and was originally feeding the red led 7X7135s but the dimmest mode was too bright so I removed 6 of them.
There was also a leaky 7135 or two on the board since the red led was dimly illuminated even when the light was off but the battery was connected. Removing 6 of the 7135s helped stop the leaking and helped make the lowest red mode dimmer than the white and the red led is still really bright with just a single 7135.
I did this mod for someone who is a pilot instructor and they wanted a red light to stop them from being blinded when flying across open water in the darkness so I made all the changes to anduril with not blinding them in mind. The light switches between the red and white modes with a triple click, and always starts on low when the modes are switched. I also added a shortcut to the red mode while the user is in the white mode.
I’m not familiar with C or anduril 2 so it was hours of trial and error, changing one value then flashing it and seeing if it was the right parameter until everything was perfect.
