DIY hand-held electricity generator for flashlight


Hello!
Today I will show one interesting homemadenamely a handheld electricity generator for a flashlight do it yourself. For it we need a drive from dvd or cd.

1. DVD, CD drive
2. Light bulb
3. Screwdriver

The moving part must be removed from the drive.

Now in one of the gears, namely in the big one, it is necessary to make a hole of a small diameter.

We insert a pin into this hole along which the moving part moved.



Now we connect the bulb to the wire, and then we begin to twist the pin clockwise or counterclockwise, this changes the polarity!





That's all! If you wish, you can install this in some kind of case, and when there is no light, the batteries have run out, etc., this mini generator will help.
Thanks for attention!
