Charger of electronic gadgets, using AA rechargeable batteries, photovoltaic panels, and two thieves, two joule thieves that is.
All parts and components are recycled from old electronics broken yard solar lights. Only new parts are rechargeable batteries and thin coated wire for toroids.
This is my first Instructable so forgive me if it's rough, I will make every attempt to improve it, so questions comments and all constructive criticism is welcome and expected.
Step 1: what you need
photovoltaic panels- I got mine from old solar garden lights, that got run over by a car and wear only thing that did not crack
toroid-from old PC I got from garbage
L7805 voltage regulator, 1N4001 diodes, 2N3904 NPN Transistor- all from broken enlarger timer
miscellaneous wires from many broken things I horded
The only thing I buy is enameled wire, but you can reuse old CAT5 wire too.
And some sort of an enclosure for whole thing to fit in I used Altoids tin but I also wanted to use Apple USB Power Adapter box, Its clear so its awesome, maybe next project.
So My green twist is two twists. All parts wear, and can be for you, re purposed from broken, discarded electronic waist, And second twist It uses solar power to use however you like or want.
