iPod Shuffle Charger

iPod Shuffle Charger

The iPod Suffle is a really cool piece of hardware. One of the drawbacks, however, is that it has an internal battery that is recharged via USB power when it is plugged into your computer.
To make a Shuffle Charger you will need the following:

1 +5VDC Voltage Regulator
1 9v Battery Snap Connector
1 Project enclosure
1 General purpose PC Board
1 9v battery
A female type A usb connector. You can find this off of a USB extension cable, or maybe some old junk hardware somewhere. – $0.00 – $6.99

The first solder you’re going to make is from the 9v battery clip to the voltage regulator. Solder the RED (+) wire to the INPUT on the voltage regulator. Check the back of the box to make sure, but this is usually the left-most pole.

Next, solder the white, black, and green usb twisted wires, AND the ground (-) from the 9v clip to the ground on the voltage regulator. This is probably the middle pole on the voltage regulator.

Finally, solder the (+) RED wire on the USB cable to the OUTPUT of the voltage regulator. This is probably the rightmost pole.

Next, double check your solder connections to make sure they are correct and there is no solder bleed-over.

Now connect the + probe on your volt meter to pin 1 on the usb connector, and the – (black) probe to the other pins. On each pin the volt meter should read +5v. It is critical that you verify the output voltage for each pin. If you mess this up you could break your Shuffle!

If you are satisfied (and brave), connect the Shuffle to the usb connector. It should blink green, then yellow and green, and finally blink yellow steadily. If it does this, then your charger works. Congratulations! If not, check your solder joints and get your volt meter out again. And pray you didn’t fry your shuffle!

Finally, mount the parts inside the project case. I cut a notch on one end just wide enough for my usb connector, and filled the empty space with foam I had lying around from something I had shipped to myself. There’s no perfect way to do this. Just do what you think works. Heck you don’t have to mount it at all if you don’t want to!

Okay, now grab a beer and watch as your yellow light blinks on-off-on-off-on-off-on-off…
