You could also flash Anduril for D4 with Aux support. D4S might work, but it’s not ideal as the part for the thermal regulation is made for a bigger part. Also the level mixing is off, as the D4S has more AMCs.

see here: http://budgetlightforum.com/node/65593

But the whole process of installing (and flashing) is not a newbie task

So if I understand correctly, the LDO on the D4 TIR board causes it to have only one level of light? But if you took out the LDO then you could have low/high? I’ve never used aux lights before, so I’m basing it off of the H03 lexel driver with anduril, the light under the button has a few modes, high, low, flashing, off. Would this be the same with the stock D4 TIR board? Or would the LDO need removed? What are the implications of doing this?

I know I will need to flash the D4S firmware, or D4 anduril with the aux code added. But the LDO has confused me.

Sorry for all the questions, I want to learn, trying to understand.

Yes if you want high low then the LDO can be replaced with a resisor, which fits 0603 to get between the pads or build with resistors based on 3.7 not 2.8V

The LDO is to stabilize the current while battery voltage drops

Ok perfect, thanks Lexel!

Edit: any idea on when the D1S direct view TIR will be ready?

Edit 2: also, will building without LDO drastically increase current?

1. they are ready

2. you will need to use a resistor to get same brightness if you mod a board which was built with LDO, or it gets a lot brighter

Thank you for making these available, Lexel!

I am very interested in modding my D4 with an aux board.

I want the aux LEDs to act as a locator light, with a brightness roughly comparable to a large tritium vial. They shouldn’t light up a dark room.
I guess your “0.15mA” brightness level is most suitable for that?

Can I order a D4 board with a trimmer installed instead of an LDO so I can adjust current without soldering?
If yes, what is the approximate adjustment range for the “0.3mA” and “0.15mA” levels?

Problem with D4 board is it has no space for a regular 3×3mm trimmer

2×2mm trimmers may be possible to fit would need a new design and are pretty expensive so I never invested in that build

It is possible to replace the LDO carefully soldering with a resistor and you can use high/low feature with D4S Firmware to get on low tritium brightness
or just build at very low constant current with LDO

Ok, I had suspected that there isn’t enough space on the D4 board.

I will decide on the colors soon and place an order with you.

Does the D4 board work with FF PL47?

I was doing now a full upgrade of D4S Aux board to rev. 3.1
I ordered Rev. 3.0 2 weeks ago, hope to test the new full battery indication

new:
- 3.9-4.2V additional outer ring (grren default) lights up in addition to main Aux LEDs
- Solder jumper to select classic unstabilized high/low LED level from Firmware or constant current with depleeting battery
- 2 indipendant Aux LED channels with trimmer reduced to one, so the full battery got a trimmer and fits 2 layer
- new indipendant voltage terminal
- reverse polarity protection
- standby drain when in LVP reduced from 40uA to 2uA
- smaller IC package to get additional space
- bigger markings of the trimmers
- rounded component pads

right side rev. 1.1 compared with latest design on the left side

Nice changes. Having the middle open should help when connecting everything and you still managed to fit 5 more LEDs

I think I recognize a chip or two Wink

What’s the current status of the D1 and D1S boards? Which approach do you like better: direct or indirect? Cool idea, never really thought about illuminating the gasket of a reflector light.

I have not tested the indirect so far because i am not having a light to do
the dirdct is more work with sanding and Gasket but I like it better

The boards are here ready to be build

I have also a version in mind with LVP that also needs reverse protection,
but so far the demand for those bord is almost non existent so its not really worth investing
