wow, this looks stunning. great skills!

CRX is at it again, amazing job as always. :+1:
A light made just for plumbers. :smiley:

:face_with_monocle:
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 :+1:

Thanks guys :+1:

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 :slight_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! :person_facepalming:

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… :smiling_imp: LOL

Practice!
Yeah it can be messy stuff, you get the hang of it after using twenty tubes or so… :smiley:

:+1:
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.
