I have created a new blog (Lummi Lab's) which will be updated with development work.
Not all will come to fruition & is purely a way of documenting & sharing work in progress.
I also really wish I'd done Chemistry @ school
My first entry is my working prototype of a Wee with XP-G light engine design.
Please check out Lummi Lab's here http://lummilab.blogspot.com/
Please Provide feedback & subscribe for updates
Or to be specific…. The bit on the left fits into the bottom of the light engine. The ‘button’ on it is sprung and connected via a resistor to its outer case from which it is normally insulated. When you tighten the Wee, the battery touches the button of the insert causing current to flow through the resistor making a ‘low’. When you tighten further, the button shorts against the outer case and gives you ‘high’.
I know this because my Lego man told me when he was making it...
Well Jay R your pretty much figured it out. The small component on the left enables twistable variable brightness. From off to infinitely variable to high. The VBC (Variable Brightness Component or Control) could be thought of in a similar way to a potentiometer, however it is a far simpilar & less mechanical than that.
All to be said at this stage is its thanks to Quantum Tunneling!
How Techy is that! Wee VBC with Quantum Physics.

I see no way this could be installed in a already existing light. Thereīs no room at all. The only available space in these is used by the rechargeable. Of course it might be possible to just pop it into a light resulting in much less useable threads. But I doubt it.
The light in the video doesn't appear to have any reflector, and there is no way to remove it from the existing Wees (it's part of the body)... Too bad, I would love to have this setup in my BB Ti Wee...
The VBC is not something I think I can offer as a drop in for the current Wee. As it is the overall length may need to be increased by a few mm's. Also I would like to begin using the XP-G which calls for a different parabolic curve on the reflector. As many are aware the Wee's reflector is all part of the front body.
This is very much work in progress & is subject to change or even not happen. However i do believe there is or will be interest in a VBC Wee & would love to be able to offer these as a production item. Time frame is unknown at this time? It depends mostly on how things go with the machine shop. I would like to think we could get something started in the early part of the new year. I hope this does not appear as a tease, I just wanted to start sharing some R&D again.
Quantum tunneling is when quantum particles (electrons, quarks, neutrinos, etc.) spontaneously jump across an insulating barrier, presumably instantaneously, regardless of the distance being crossed. It doesn't violate the speed-of-light law because the probability of each particle tunneling through the barrier decreases as the barrier size increases, so when you zoom-out far enough that you get back into the realm of predictable physics, the average time it takes for an entire "batch" of particles to tunnel through the barrier is equal to the time it would take them to travel that distance at the speed of light if they all went at once instead of hanging out and waiting to jump.
So I'm guessing the switch has some sort of an insulator that can vary in thickness as the switch is compressed, and electrons jump across in varying amounts as quantum physics allows.
