What do these 2 items have in common? Well you might carry them together in a purse or backpack. By the end of this instructable they will have a lot in Common.
I'm gonna show you how to take the guts from an old LED landscape light and make it into a portable phone charger. HERES THE DISCLAMER " I HAVE NO IDEA HOW ALL BRANDS OF CELL PHONES WORK AND I"M NOT AN ELECTRICIAN SO TRY NOT TO KILL YOU NEW $400 PHONE. I JUST KNOW IT WORKED ON MINE"
Step 1: Stuff you will need for your Solar Cell Phone Charger
First you will need..
Altoids tin (empty)
Solar Cell small 6 v 3 1/4" x 2" or smaller
(I used the guts out of a cheap landscaping LED light. If you can find one that doesn't work its prob the battery, and we don't need them)
NOTE: I'm not electrical genius but every cell phone I have had in the last few years has a 3.7v lion battery. The wall charger I have for my phone now puts out 5.7v and so does the solar cell??? So I'm guessing that any solar cell 3v to 6v might work. My old wall charger works for my phone and it's out put is 3.7v. I have tested little solar cells in the sun and 3v cells will put out 4v easy. If you read the back of your wall charger and find out what the output is and match that to a solar cell you should be in business.
Velcro (with the stick back)
Plug in charger (that fits in your phone an old one car or wall)
Soldering Iron (solder)
Voltage Meter (If you know how to use it ..or you can wing it and maybe blow up your phone)
Hack Saw Blade
