After an enforced break waiting for various coloured LEDs, resistors, AUX-boards and adapter boards to arrive from various places, I was finally able to do my next FW3A mod.
This one was time-consuming to say the least.
I tried an ATTiny1616 driver upgrade, which I’d never attempted before. On top of that, I decided it needed custom AUX LED colours on a Tri-LED AUX board, and I needed to find the right resistor values for the different colours.
I sourced the T85-to-T1616 adapter boards from OSHPark. The photos show 3 adapter boards next to a MicroSD card.
It took me quite a few tries to get the T1616 MCUs mounted on the adapter boards properly. Once on, I could flash a custom Anduril build, based on Adair’s T1616 configuration, but with ramp configuration from @INeedMoreLumens and with a few of my preferred configs.
The next challenge was to remove the old T85 MCU from a FET+7+1 driver. My first attempt failed and resulted in a destroyed driver - I must have used too much heat, and the MCU contacts lifted off with the old MCU.
After the second attempt succeeded, I could mount the adapter board and wire up the 3 AUX LED channels.
The next step was to install pink, warm white and ice blue LEDs on a Tri-LED AUX board. As I hadn’t used custom colours before, I needed some trial and error to find the right resistor values for a balanced, not too bright setup.
After mounting in my purple FW3A host, along with 5000K 519As, I could finally be sure of having found the right resistor values.
The colours go well with the purple host. I love they way the colours only partially mix with the Tri-LED AUX board.
