Probably took too thick wires for the aux LED on prtototype
on first assebly I had the driver twisted to align to the heads cutout and ripped the pad where the optical nerve was off
so disassemble again, looks messy with the heat paste all around
Prototype, got a small bug, but can be used without the LVP chip, the bridge pads were designed on it so no big deal
but the fab let me down not cutting out the 20mm boards from the panel, so I got ordered new ones
Also made a quick thermal test, that thing gets hot fast
if you flash driver and remove the optical nerve resistor you can solder there the Aux supply
then flash a firmware variant that supports the Aux LED option
Removed 2 7135’s from my FW3A. It still thermal throttles with a full battery. But with a more empty cell it can sustain max regulated output for a long time (probably indefinitely). I did a calculation to determine how much the efficiency actually went up, and it wasn’t much… But still technically more efficient than the pwm equivalent with 8 drivers.
I was worried that the mode spacing (or ramp rate) would be non linear between the 1x7135 and 6x7135 sections, but it’s still very good.
25mm… I think there may be a few diffusers from other manufacturers that could fit. One that comes to mind is by Nitecore, with a 25.4 mm diameter. One could line the collar of the diffuser with some aluminum tape to get a snug fit.
Experiment-ing….little 0603 led’s are a PITA! Touchy little critters too…poofed a few! Actually had the little 0603’s fitted in the trit holes……
More Purple than Blue, the Green trits are about twice as Green, but the camera dislikes UV…waiting on the micro band-pass len’s now….might try the band-pass film….we’ll see….
