[SALE] lighted TIR boards, D4, D4S, ROT66, MF01 multicolored with low battery waning and LVP

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 3x3mm trimmer

2x2mm 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.

That is some amazing work.

Does the D4 board work with FF PL47?

Sent you a PM Lexel

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

I could send you my D1s as a test unit if you would like that?

sure

Prices updated

new LED test boards

Astrolux S42 and S43 planned with LVP

Astrolux S42/S43 Aux board design drawn going in production soon

have changed to sort of hybrid pads 0606 tiny and 0402

uncut video in full lengh making an order from BLF member pogushe
He ordered one D4 Aux board for 5.7€ plus shipping

So I think I got to increase the prices as its even worse than on driver sales
