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.

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?

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?

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.

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)?

Brilliant switch cover.

Manufacturers need to take heed, or someone’s going to accidentally incinerate their baby and end up suing the manufacturers for selling a known hazardous item. Think hot coffee at the drive-thru window. Not to start a lawyer rant, just saying.

I’d really like a clearly perceptible detent click stop on the tailcap or head-body junction for turning to a safe locked off position.

Or a safety indicator — little RED LED when the tailcap is tight, even when the light is switched off.
A “loaded and dangerous” indicator.

It’d be nice to also have a little GREEN LED when locked out.
Oh, but how’d you power that? Hmmmm.

That’s why they put safeties on guns, come to think of it. To avoid making unwanted holes.

The aux LEDs don’t use PWM. It’s basically connected directly to power, aside from having one or two resistors in the way, and an on/off switch. The MCU turns it on and off, and adds/removes a resistor. So the brightness is controlled by changing the voltage.

The reason why Lexel’s aux LED boards (the ones I’ve tried, at least) don’t work on low mode is because they shut themselves off at low voltage instead of allowing the LEDs to be dim. I haven’t heard anything before this that they’re supposed to work now, but he did ask like a week ago why it wasn’t working.

Since I do not have the programming stuff yet, I only tried the AUX Boards with a very depleted CR123. They were merely glowing, but not shutting off.

Thanks for chiming in. So the worst that could happen is low mode just not working.
I’ll give it a shot once everything arrives.

So my first steps with Atmel Studio were not very successful Big Smile
As I’m not a linux guy I’ll have to see how to proceed.

I understand that using linux and the supplied scripts would be way easier though.

Editing cfg-emisar-d4.h + hwdef-Emisar_D4.h to inlcude aux is not that hard, but compiling the hex in atmelstudio is beyond me for now.

HELP!

Trying to flash my D4 to Anduril, but I can’t get AVRdude to run.

Every time I try running it the command prompt says “Does not have permission”. And a popup window appears saying the app is not allowed to run on my PC.

I installed AVRDude last week briefly. For the first 20 minutes it worked and behaved normally, but now the app won’t even run. Uninstalling and reinstalling didn’t help.

Using Windows 10. This is a home PC and I’m the only one who uses it. I have admin privileges and have no idea how this happened or why the app stopped working.

Any ideas? or suggestions for alternate programs that might run?

Unlikely this would help, but if you are anywhere near Santa Barbara you can swing by my place and program your D4. I a necessary parts and a pretty recent version of Anduril for the D4. Otherwise, your problem sounds pretty weird, the only thing I can think of is be try shutting of your PC and waiting a bit, then turn it on and try again.

I finally got my Lexel lighted TIR board installed in my D4. I like it!! Not easy to install, but not that much harder than flashing my D4 with Anduril.

I think you are asking if I can control the aux light board with the e-switch. I can not. ToyKeeper gave me some tips how to change the firmware to be able to do that, but I decided to just use as is. The current draw of just the aux light board is 0.7mA. I am using a 1100mAhr 18350 cell, so it will go a couple months before aux board would draw the capacity significantly. This is my EDC light, so I am charging the cell every week or two, so I don’t see the need.

It’s bright enough to navigate around at night with just the aux lights on, at least to see if there is something in your path.

I glad I did this. Smile
