Emisar D4 Mods

Here is my old post of my switch mod

Same as already suggested.

That’s cool, what’s happening there?

Really simple. Cut the trace on the single 7135, cut trace and isolate a single led on the quad, replace with a red xpe. I did it on a Emisar driver first, then ordered a TA driver from Lexel that he drilled a hole and separated the single 7135.

I adjusted Anduril ramping tables.

The way the ramping works, single 7135 for the lows now runs the red led.

:+1:

How I wish the Proton Pro would of worked.

Very clever!

I was originally planning on a single hi cri led. Still might swap out later.

Firelight2 I am waiting on your switch bezel. I looked for some washers at the hardware store but a no go. Did you get it glued on?

Wow. Nice file work on the washer. :+1:

Yup. I ended up installing the washer on my D4 with bare aluminum head. I removed the flip-up cover in order to install the washer. The washer is glued on with Arctic Silver Thermal Adhesive. It can take the heat, is strong enough and the silver coloring helps any bits of glue blend in with the head.

I think it looks great! Much better than the flip-cover did. Downside is the washer doesn’t provide nearly as much protection from accidental turn-on compared to the flip-cover.

For the washers: I also looked in my local hardware store and didn’t find anything suitable. Steel finishing washers were available, but I find them too hard to file down. Nickel Plate Brass works well because the brass is easy to file down with a hand file and the nickel plating looks great. Best place to find them is probably Ebay or Amazon. The size you want for this light is #14.

My plan now is to flash Anduril in this light and install one of Lexel’s aux LED boards.

Hm… I wonder if Lexel sells LEDs to light the switch. I’ll have to check.

^ That is an awesome job. That is how the Emisar light should of came out of the box.

I tweaked Anduril to give me memorized level from lockout instead of momentary moonlight. Just for those time I need to pull it out and see something for a few seconds.

I pm’ed AEDe about a switch bezel(he had some nice ones for the H03) but didn’t get and answer back. I think I will have to give your mod a try.

I think with the washer bezel and the firmware tweak this could be a sweet EDC light.

I don’t have a D4s, but it looks like the switch is more recessed, anyone?

I don’t have either.

But from here: Emisar D4S review
A recessed button, look at the picture

Yeah, That is what I am seeing. Wish they would of done this on the D4.

Wow, amazing mods! chadvone’s is genius. I don’t have anywhere near the required skills or patience!

I can confirm the D4S button is recessed 1-2mm.

Showing that to my wife :smiley:

I bought Lexels Aux Boards for the D4. Does the D4 Anduril Firmware support the Aux switch, or do I need to install the D4s variant?

If it’s the same as mine, there’s no firmware involved. The aux board is hardwired to battery plus and minus

I asked a similar question of ToyKeeper not too long ago. I asked

I am looking to buy one of Lexel’s aux LED boards to add to my D4. He has told me the D4 driver can be flashed with the D4S FW to control the aux LEDs. What are your thoughts on that?

Here response was,
I wouldn’t recommend running D4S firmware on a D4 with Lexel’s aux LED board. There are a few problems:

*_Thermal regulation won’t work, because it’s configured for a bigger host.
The ramp shape is wrong because it expects 3×7135 chips and only has 1.
Lexel’s aux LED board can’t do the low brightness modes, just on or off or blinking.
So I’d recommend making a custom build for it. Start with the D4 config, enable the aux LED options, and tell it to skip the low mode. The lines for that are in the PL47 config. It may also need one line copied from the D4S hwdef file, to tell it which pin the aux LEDs are on._*

Using the D4s Firmware the current gen of Lexel Aux Boards should work in both low and high modes in the D4 (per Lexel).

so we need the custom config with AUX enabled and the hwdef part. I do not have a programmer yet and I have never tried to edit firmwares, so I’ll have to see if I can manage that.

I would be interested in knowing why low brightness is not supposed to work, maybe it has to do with pwm being supressed by the extra chip/controller on his aux board (I have no Idea :D)?

Are there any pictures of the H03 switch bezel?
