two or one small solar panel

Step 2: Prep the usb port

make sure your usb port has two inches of wire to work with. you can cut of the white and green wires, they are not needed for this project. 

Step 3: Soldering the USB to the 5 volt regulator

the side of the regulator with the writing on it should be facing up!, be sure to have the writng facing up when doing this step. 
solder the red wire from the USB port to the 3rd leg of the regulator (3rd leg is output) then solder the black wire to the middle leg (middle is ground)

in the picture you cant see the writing on the regualtor but it is there. be sure to have the writing side facing up! 


Step 4: Prep the wallet

put the regulator and usb to the side for now and prep the wallet.
first off, remove all the wallets contents then cut two small holes on each side of the wallet (as seen in picture) 
These two holes allow the solar panel wires two run through the wallet while out of sight.

Step 5: How to connect two or more solar panels.

when connecting two or more solar panels it is important to think of them as batteries. negative to positive. doing this will double the output. 

Step 6: Connecting the two solar panels

Solder a long wire ( a little bit longer than your wallet) to the negative solder joint of one of your solar panels. then run that wire through the holes (holes you cut)

Step 7: Connecting the two solar panels

now take that wire and solder it to the positive side of your other solar panel. after doing that you are left with a positive and negative solder joint that hasnt been touched. a positive joint will be on one panel and a negative will be on the other panel.
only bad idea about this is you need to leave your wallet out to get power. People would see it and take it.

Well I use it and never let it outta sight. I don't think anyone would leave their phone and money lol I wouldn't. Also when I made it I had a use in mind, leave it on a car dash board or something similar.
In my city, if we leave something of value in view in the car, you can get a ticket!
Now if only this could recharge the currency section of my wallet...
Hey maybe that is possible haha.
