Hand cranked torch

Little project I did for UK electronics mag Practical Electronics. Ideal bedside torch - at night, you can still see the LED faintly glowing days after last winding it.

Much better durability than commercial rechargeable battery torches. I have capacitor-based hand-cranked torches still working well after 15 years!

Pics tell the story.

Neat!

Can you adapt it to falling weights like a grandfather clock?

You'd have to add a few more geartrains. But I like the idea!
