Make your own Crude Shaking Torch (Emergency Flashlight) Matt: Here's what I want to know about these Joule thief circuits. Is there a way to make a voltage-regulated switch to bypass the thief above the minimum voltage of the LED? Instead of 24% efficiency at 5V, the system runs like a standard flashlight until the cutoff voltage of the LED is reached or almost reached, at which point something switches to disengage the direct power delivery path and engages the thief circuit. Sure would improve the efficiency of the circuit tremendously.

Thank you for sharing all of your knowledge. Though I don't think I will ever make some of the things you make, it is still very interesting and useful. I am hoping one day to be able to start making my own small and very low power projects just for fun. Just wish i had the understanding of circuits and electricity that you have. Would you mind sending me 1/32th of your brain so I could start?
Thank you again!

Been planning on a kinetic charge phone case and I stumbled across this video. I think this video would help quite a bit with planning and design, thank you so much!

Great Scott - his hand movements are so smooth - where could he have mastered such perfection - a master indeed of the back and forth motions i see!

If a propetual motion machine work then we can get infinite energy without friction or more fancier word frictionless propetual motion machine

Anyone an idea to use different coil? Like using a longer coil and less layers. Maybe less magnets too?
I was thinking of using a stronger led.

Springs in the pipe to make it easier to push the magnets back, stuck to the magnets. or a 3d printed plastic spring/ each end of the pipe.

Metric is so much nicer, everything just needs to be multiplied or divided by 10 instead of shitty multiplication by 3 or 12 or whatever

Imagine one day we could power the world with this like if you run it would charge things like your phone or computer you get the point
