I made two of the new version, one for a D4v2 and one for a KR1.
I started with the KR1 :
To have sufficient height for the 3mm inductor I used 0.8mm (0.9mm actually) boards with a spacer, as bonus they have 2oz copper weight.
Eurekatronix B35A boards have the holes at 90° so I drilled two new holes for the wires.
B35AM 4000K 9080 installed and at the lowest level (3μA) :
With the Ledil Olga RS
I haven’t yet made an AUX board for it, which is a good things because I planned to have the optic sit on the 0.9mm AUX boards, except after testing I see that raising the optic by 0.9mm degrades the beam quite a lot, a small but obvious egg yolk on the spot and the ghost LED image at the corona that JaredM talked about. I’ll have to make a big hole for the optic in the aux board.
About the driver, I configured it to 3A for the B35AM, it can take more (up to 4A) but I prefer a longer turbo.
That said I’m wondering if the thermal regulation is actually working, I haven’t tested that before because it was only on my test bench with the LED on a heatsink, the temperature reported is also low, I wonder if I messed up something in the code, when modifying the VREF maybe ?
The little flash that I mentioned at turn ON with the MP3431 is still there but greatly reduced with the hardware delay on the HDR FET, I’d say it makes a very short ~0.5mA flash now, hardly problematic.
This is starting to look pretty good ngl
