Wind-Up Torch

Alas, I think my electronics "career" may be coming to a close. But first some world history. Wind-up torches / flashlights have been around for a long time: The image shows a German device from World War I. However, shortly before 2000, it became possible to use entirely new technology -- if one pushed it. So I had a design published in 2000, which was the first wind-up torch to be powered by super-capacitor -- and my first electronics "cover". Then in 2002, the Faraday Flashlight (not my design) appeared on the market -- using similar new technology, but a different concept for the generator. Having said this, my last electronics article should be published in July this year (it has been accepted) in Everyday Practical Electronics -- the UK's no. 1 electronics magazine. I wrote it more than ten years ago, and mislaid it. And it is a wind-up torch. My mind is still full of designs, yet my electronics tools and components are now packed away (see also Writing Ambitions).
