NOTE: i am not responsible if u burn your battery please use correct values or resistors and diodes! do it on your own risk!
Step 1: THINGS YOU NEED
things you need
-a diode mine was 1n4001

-some wires (thin)
-a usb chord having a very thin wire
-a small rechargable lithim ion battery , you will find these in mini helicopters,blue tooth headsets
Step 2: CONNECTIONS
take the wallet and cut the pouch containing credit cards! wire the led attach a resistor (dont know the exact value). attach the led to the lithium battery.. now take the usb chord and attach a diode
NOTE:place the white end of the diode in the direction of the battery
attach the usb chord with correct polarity with the battery
