Hat This one would be taking the hat off if he had some arms!

Great even being small Wink Beer

CRX, may I ask how you constructed the head on this?
I see a resistor on the MCPCB. When I think about it, you could have a simple resistor in place of the “driver” (or if you were feeling cheeky, direct wire), and a simple plate for the positive contact (electrically insulated from the body)… And then, yes I think I see it, a bridge from the LED- to the body. Eliminating the need for a driver, a real pill, or more complex wiring.

Sublime work pal, wish I had the time, patience and skill Beer

Icing on the cake being the choice of fitting, I did my apprenticeship and 16 years as Electrical Maintenance Technician at Yorkshire Fittings in Leeds Thumbs Up

Yes, just about exactly right.
There was no space at all for a driver and a clicky switch so what we have is, for the pill, a cutting of threaded brass with the MCPCB soldered directly to it and three layers of kapton tape on the underside of the Noctigon.
A piece of 0.3mm copper sheet shaped & formed around the Noctigon to make the positive cell contact and serve the MCPCB +pad, also coated in kapton.
This is held in place with JB weld with a clear space made for the cell+.
I used a 1ohm resistor between the copper sheet contact that’s bent around & sitting on top and MCPCB positive to give a respectable 800mA startup current draw, DD is a bit much.
The MCPCB- is just soldered over to the pill.
I made a very simple light with scavenged parts, BLF style Wink

Cool, thanks.
Here’s another wee light I made from 20mm brass conduit bushes Smile

Thanks CRX, works of art as usual. Or as always, actually.
I think I came up with a better question: How do you work with JB Weld? I can only ever get it to stick to things near my workspace, and not what I’m using it on! Facepalm

CRX, this is very beautiful. Thank you for sharing with blf community! Does this mean this is ‘direct drive’ flashlight?

Looks intriguing. Not sure it is quite floody enough though… Evil LOL

Practice!
Yeah it can be messy stuff, you get the hang of it after using twenty tubes or so.. Big Smile

Pretty much yes, with a current limiting resistor.

Planning on a larger version with reflector, driver and tail switch Wink

Added secondary red LED, magnetic tail and GITD details.
