Step 1: Materials
Lots of wires
dremel or something to cut the altiods case
9v battery clip
Resistor (im not really sure which one)
female usb (www.http://www.mouser.com/Search/Refine.aspx?Ntt=806-KUSBX-AS1N-B
this is a pic of the regulator
Step 2: Hooking Up the Battery and Switch
Take the red wire (positive) from the clip and solder it to one end of the switch
then solder the other end of the switch to the resistor and solder the resistor to the positive side of the led
Step 3: Led to Regulator
Next take a black wire and solder it to the middle pin of the regulator aka the ground.
Step 4: Wiring the Ground
Take the wire you soldered onto the ground (pin 2 of the regulator) and solder it to the negative of the battery.
Ok now the confusing part. Solder another wire onto the negative of the battery. Take the end of that wire thats not connected to anything and connect it to pin 4 of the usb. Sorry if this sounds confusing
The picture should help a little.
I also tried to make a schematic in paint
Step 5: The Case
I also drilled a whole in the front for the led
Next i took my dremel and put two slits down the side for the usb and then u just put everything in
