Emisar D4 Mods

How’d you make the metal button CRX? It looks lovely! :sunglasses:

You should start selling metal button kits for this light on Mountain Electronics.

I think Yammie could do a much better job than me with the buttons for other people


I just used magnets, bits & pieces and silicone.

PM please!? Zero liability on your part, im tryin to learn usb circuitry and EVERYTHING helps. Just for knowledge, dont have a D4 to risk it lol!!

BTW Awesome work as always! And thanks for helpin on my threads too!!

Me too please

The Xeno XRD ring would be perfect for my D4. Does it need to be modded or is it perfect as is?

The specs say as to the aperture of the Xeno XRD ring: Ø23.5mm, thickness of 1.5mm.

I measure the widest point of the threads on my D4 as 23.2mm so it should slip over but you may need a copper ring/ shim in the tail as I don’t know if the thickness will obstruct contact on non modded models?

Thank you CRX. I guess my search continues. I wonder if I could find a copper pipe fitting that would work as a spacer.

Maybe tinowrx could give a definite answer on this?

hi

as CRX says (with his measurements) and my use, its fits perfectly and slids over the o-ring. All you need is a copper washer or a paperclip to go inside the tailcap. i used a paperclip as i had one to hand without going to the shops to find a washer

@ jerommel:

Sorry for the late reply. But i Barely have got time to do these little mods for myself these days.

Hope that you will find someone that can make it for you.

The ideas some of you here have are great!
It’s an honor that i can copy them.

I just had to ask.
Wish i had a lathe…
Even with only a chuck on an axle i could do so much more…

Although not being able to do some top mods as CRX, and also not having some tritium vials, I decided to add extra “glow” to my D4 :sunglasses:

Cool :+1:

Just noticed that CRX invited other modders to (t)his thread so I proudly add my little RGBW mod:

RGB + white, new 5 channel ramping driver:

Beam with single LEDs:

All in:

Very nice :+1:
Yeah I was hoping people who modified their D4’s would post here too, good to see everyones ideas.

Green Lantern and HAL 9000:

Got the green D4 yesterday and couldn’t wait to tinker with it.
Changed the driver against my new one and added a green SMD-LED to the MCPCB. It serves as a indicator LED, lit continously when light is off and flashing each 4 seconds when the light is locked. Can be deactivated of course with a few clicks. The right one is my previously presented RGBW D4 (with the red LED as indicator LED).

Green Lantern and HAL 9000 :smiley:
Now that’s just cool :+1:

Do you happen to take orders? I have no skills whatsoever to even remotely hope doing those mods, don’t even have the tools, but I would be glad to throw money at you for one of those USB-chargers and magnetic tails. Interested in the LED mod in the picture just above too, but it’s not made by the same person, and anyway it might be more difficult to sell unless the full D4 flashlight is sold.

There is some great work on this thread. Thanks to all of you for posting. This has motivated me to make some mods to my light.

Magnetic Tail - I was able to source my magnet for the tail from K&J Magnetics. This magnet is being used in place of the spring and pcb so it contacts the body. The best size and strength for this in my 18350 body light was 7/8 x 1/16 or 22.2mm x 1.5mm. To remove the tail pcb I used my soldering rework heat gun. I found 350F to be the sweet spot and the board popped right out with the glue staying on the board. Quick cleanup of any remaining residue and I super glued the magnet in. I did have to file the body of the light a bit to fit to the new magnet. This was the most time consuming because I didn't want to overshoot and cause a poor contact between the body and the magnet.

Deep Carry Clip - This was more about finding the right one. I used a clip from the Nitecore Store from their parts page. This one is: "Version B for MH10, MH12, MH20, etc." The only thing left to do was thin the arms of the clip to fit the grooves on the light.

Next mods - Researching the ME4056 board to see about an integrated USB charging solution. Thin the arms of the clip some more for a better fit.

Nice :+1:
