What did you mod today?

Yesterday I modded D4Ti V1 (I hope that I can still post it in “what did you mod today?” thread) :wink:

It has:

  • Anduril 2,
  • 2A KR4 constant current driver,
  • Nichia Optisolis 3000K.

First step was to limit default 5A current. So I modified ramping table from cfg-noctigon-kr4-nofet.h.
According to test by djozz, I set the max to 410 (410/1024*5000 = 2A). At the ramping level 130 it should make 400 lumens, 150 (turbo) is 500 lumens.

max_pwm = 410 was set in source code of level_calc.py. Command used to generate the table was:

Here is the table:

To make soldering to VR21P4 easier I used little helpers:

Tint / beam comparisions (5000K white balance):

Those pictures are at max regulated levels:

Notes:

  • leds don’t light up at all until ramping level 3,
  • D4 Ti V1 can’t accommodate E21A quad MCPCB from intl-outdoor (there are bigger than standard Noctigon 4XP boards),
  • D4 Ti V1 can’t accommodate AUX led board from intl-outdoor,
  • biggest wires that fit through hole in VR21P4 are 24 AWG. 22 AWG from intl-outdoor (and probably other places) don’t fit.
