CRX Stratis Lumina - 5th BLF, O/L Scratch Made Light Contest

Hello, welcome to my build thread.

This years flashlight will be made from copper and wood, C101 1.2mm copper sheet and Indian rosewood.

I have never worked with wood before so this should be an interesting experience.

The format for the light will be similar in nature to one of my previous Monolith builds except better Wink  Incorporating alternating stratis of copper & wood and be similar in size to a credit card although a lot thicker.

I have some stuff here but have ordered special materials for the body of the light and waiting for them to arrive, some members have no patience  Big Smile so I have made some images up with the concept I am planning.

The light will be a quad emitter setup for the main lumina powered by a 17mm 105c Nanjg driver and also have auxiliary red and possibly UV emitters operated by a secondary momentary switch or mercury tilt switches so depending on how the light is positioned these will be on or off, see an example of mine here

The main driver will be a Nanjg 105c 3A with MoppyDrv firmware and operated via a red tritium momentary switch on top.

The light will be powered by a 1200mAh lithium polymer cell with a charger board built in wired to a micro USB port.

These images are measured, cropped and placed manually.

Interesting, what emitters did you have in there?
I was just planning on a low power 5mm UV emitter in the centre of the optic, probably 395nm or above as I noticed 365nm gets blocked by the plastic. I might also drill a centre hole in the optic but these decisions are made during the building.

I would definately go to a UV 365nm Emitter like Nichia 276A which needs no filter blocking visible light

Then you need to drill a hole

For that picture someone had hard driven 365nm and thought it were 395nm ones
Likely 1.5W UV radiance per emitter

A nice wee delivery today means I can get started, a slab of copper, the rosewood and some bits n pieces.
The Dalbergia latifolia has a purple hue to it which is interesting, goes well with the copper I thought.
It is meant for making ukeulele/ mandolins. Hard as rock and sounds great too Big Smile

That’s plenty of rosewood and copper to do more than one of these… Wink

Looks a lot like the Eye of Sekhmet flashlight from Silent Thunder Ordnance, but smaller! Cool

Shame Carclo doesn’t make a 40mm catadioptric optic.

What’s wrong with the 60mm one? I’m sure with your skills, you could find a way to “fit” it to whatever you were going to use the 40mm one for. Maybe a nice “setting” like jewelers do with diamonds?

I really want this light to be as compact as possible, a 40mm version would have been perfect and I don’t think filing these things down is an option Smile
Maybe could use it for a future build.
The wood I ordered is only 55mm wide but still, I’ll give it some thought Thumbs Up

Got the copper sheet cut into the rough shapes today.
I marked out the lines to cut with digital calipers, a set square and a #26 scalpel blade.

I was not looking forward to cutting the metal with a hacksaw so I thought I would try just scoring it repeatedly with a stanley knife, about 20 times down the marked lines each side and then gently bending at the weakened points until the pieces snapped off, much easier Thumbs Up
Each layer is about 1mm larger all round than required, to be made good and sanded down.

I also marked out where the glass, optic and MCPCB will be situated through the front piece.
These circles will help to keep me right when taking out this material.

I will cut the rosewood next.
