Emisar D4 Mods

How did you even make the USB bottom?

stevimagic? not sure what that means

That magnetic bottom is nice as well. How did you make the copper disc? Don’t know much about metal working.

I’m stevi :wink:

The copper disc was made from thin copper sheet. I used a magnet on one side, a battery tube on the the other and placed in a small hand vice to press a square copper piece into shape then filed it round to fit in the tail cap.
Took a couple of shots to get that right.

Wow, just using a hand vice. That is amazing. Here I thought you were milling or CNC.

What did you cut copper with? Looks as clean as using a punch.

All my stuff is worked with just small hand tools like a hacksaw and files.
The copper is only 0.3mm thick so it can be cut with heavy duty scissors into a rough shape then filed and sanded with silicone carbide paper.
A CNC machine would be nice to have though.

I’m not sure if a CNC machine would improve the quality of your work. It seems quite spectacular to me as a complete novice. Seriously, you do excellent work as far as I can tell

It would save my poor fingers though :smiley:
Thanks :beer:

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:
