KC1 keychain light is available now

So it seems this new function is implemented in the new D4V2 and KR4 - right?

From the description: “Anduril 2 firmware, user choose the tint ramping or instant channel switching, Advanced mode Off -> 9H, first menu item: 0C: tint-ramping (smooth) 1C: instant channel switching 4 LEDs can be on at the same time with full power.”

nice!! I'm much more exited now for this!

also- b45am ?? Oooohh, is that 4 x e21a?? Sorry all of these Nichia models are new to me.

Yes, same die size as E21A but 4 of them on a 3.65x3.65mm package, with less phosphor around the dies so less angle tint shift (more uniform beam), limited to 4A (6V).

Edit : didn’t see the typo, it’s B35AM.

No B35?

B35 is the whole last 2 lines of that post

Above, i asked about this and The Freeman responded, it's a typo. I thought the B45AM was another, different Nichia LED i had not heard about. Just a typo from Hank apparently. :))

A DT8 with 2000k + 5000k e21 tint ramping model would be so cool!

:+1:

Are you talking about the original KR4 driver or Anduril 2?

The driver hardware is the same and the default ramp settings are the same between the A1/A2 versions. Newer A2 versions have dynamic PWM to slow down the ramp speed at lower levels but you still need to manually set the ramp floor to level 1.

What are the differences of these 2?

anduril.2021-11-03.emisar-d4sv2-tintramp.hex
anduril.2021-11-03.emisar-d4sv2-tintramp-fet.hex

One has FET drive enabled for channel 1. It’s for K9.3, where there are enough emitters on channel 1 that FET drive won’t fry them.

The other one doesn’t have FET drive enabled on channel 1, and it’s for the 2 channel variants of D4V2, D4SV2, and KR4.

Edit: I am wrong. TK has weighed in below.

Thanks but both the above firmware are listed for D4SV2 tintramp model where else the K9.3 have its own FET and non-FET variants.

For anyone wanting to update or modify the firmware on a light they have… read the README file to figure out which flavor to use. It’s not very long. Here’s a copy of what it says:

|How to figure out which .hex file to use
|----------------------------------------
|
|1. Use the version check function to find out which flavor of the 
|   firmware the light shipped with. It should blink out a date and maybe 
|   a 4-digit number after the date -- YYYYMMDDNNNN.  Write this down.
|   Version check is 15 or more clicks from off.
|
|2. Match up the 4-digit NNNN number in the MODELS file.
|
|3. Find the newest firmware for that model.  You may need to scroll down 
|   to reach the newest files.
|
|If the version doesn't include a model number, it's older, but you could 
|still look up the model in the PRODUCTS file to see which version it 
|probably uses:

The full list is in the MODELS file. Here’s a quick summary of a few…

Regular single-color lights:

  • 0113 emisar-d4v2: D4v2 with a FET+1 driver (DD FET + 350mA linear)
  • 0114 emisar-d4v2-219: Same, but with DD FET power reduced.
  • 0115 emisar-d4v2-nofet: Same, but with DD FET disabled completely.
  • 0133 emisar-d4sv2: D4Sv2 with a FET+3+1 driver (DD FET + 1.05A + 350mA linear)
  • 0134 emisar-d4sv2-219: Same, but with DD FET power reduced
  • 0211 noctigon-kr4: 5A (or 7.5A or 9A) linear channel plus DD FET
  • 0212 noctigon-kr4-nofet: Same, but no DD FET
  • 0213 noctigon-kr4-219: Reduced DD FET power (Nichia 219C)
  • 0214 noctigon-kr4-219b: Reduced DD FET power (Nichia 219B)

Two-color tint-ramping or tint-toggle lights:

  • 0135 emisar-d4sv2-tintramp: D4Sv2 and D4v2 two-color driver with two independent linear channels (9A+9A or 5A+5A or 9A+5A or whatever is appropriate for the LEDs)
  • 0136 emisar-d4sv2-tintramp-fet: Same, but with a DD FET added to channel 1. Not usually necessary.
  • 0215 noctigon-kr4-tintramp: Like the D4/D4S tint-ramp build, but modified for KR4 hardware. Not compatible because switch is on a different pin.

K9.3 is still being sorted out. It currently uses a tint-toggle-only build which uses some weird custom code, so I need to integrate it into the main tint-ramp code for future maintainability.

  • Tint toggle only:
    • 0261 noctigon-k9.3
    • 0262 noctigon-k9.3-nofet
    • 0263 noctigon-k9.3-219
  • Tint ramp (can also toggle, but doesn’t have single-channel turbo):
    • 0265 noctigon-k9.3-tintramp-nofet
    • 0266 noctigon-k9.3-tintramp-fet
    • 0267 noctigon-k9.3-tintramp

Those last 3 need to be merged into the 3 before them, instead of having 2 complete sets.

Thanks TK

Any plan for stepped tint-ramp? Smooth tint-ramp is interesting, but to more easily reproduce a preferred tint, a stepped tint-ramp mode will be pretty useful too.

Already suggested that a few hours ago in the IRC channel. Could be done in the tint ramping config menu. Instead of “ramping or toggle” it could be:

- 0 = smooth ramping

- 1 = tint ramping disabled, always 50/50

  • >1 = n steps (2 would be toggle like previously)

I love this idea. I’ve been wanting precisely this on an LT1 for months.

What are the dimensions of the mcpcb?

Any word on whether E21A will be an option for tint ramping? I’d love to do a 3500k / 2000k…
