As I was on a bit of a roll, I also decided to attempt something new and upgrade a 1+7+FET driver with Anduril2 and an AUX channel. I’d been working on the firmware part already: here.
The software side was ready (as far as possible without having tested it), so now the hardware part also needed doing. A black aluminium FW3A (not an FW3X) had arrived during the week, so I decided this would be the light to mod.
The mod turned out to be less difficult than I’d thought. The 1+7+FET driver flashing was straightforward, following the instructions here. The driver mod for AUX was also easier than I’d expected, following this.
I used an RGB lume AUX board, wiring the single AUX channel across both green and blue to have cyan AUX on the light:
After flashing, putting the driver in and wiring up the AUX board, the moment of truth arrived to see if my custom Anduril 2 build would work.
Success!
On this one, the cyan colour is much brighter than the cyan on the lume1 lights. I suppose the resistors (after shuffling around) are set up for the lume1 driver. With the 1+7+FET driver, the AUX is much brighter, so I may have to try some different resistors at some point. Here they are side-by-side:
If anybody could recommend resistor values for the blue and green to bring the brightness down to a similar level as with the lume1 drivers, then that would be appreciated.
