Emergency Lights When The Grid Will Be Fried: How To Make A Shake Flashlight

Shake Flashlight

This shake flashlight uses no batteries or bulbs. Instead it uses Faraday’s Principle of Magnetic Induction and a bright LED to produce light without batteries. The flashlight is shaken for about 30 seconds to recharge a capacitor and it will then provide about 5-7 minutes of light. How does this happen? As the flashlight is shaken, a magnet passes through a metal coil which, when you shake, “induces” voltage in the coil generating electricity. During prolonged use it can be shaken for 10-15 seconds every 2 or 3 minutes for bright light. The light requires no maintenance so it can be left in your home or car for years, but will still be ready to produce light. The bright LED will last for thousands of hours and does not burn-out like a typical lightbulb- it should never need replacement.

  • Just shake the flashlight to charge. No Batteries Required.
  • Never needs batteries, never needs bulbs and is maintenance free.
  • Great for cars, boats, campers, homes, cottages and all emergency kits.

Here’s how to make a forever shake flashlight. I used mostly old parts I found laying around in broken electronics.

It’s also pretty good to exercise your right hand.

I think it would be even nicer to use two (or more) capacitors to double the farad (parallel arrangement). Good luck!
