This allows you to play your ps2 anywhere in the house without running long network cables along the floor. I did this as an experiment as I was tired of dragging a cable into the lounge, and I prefer to keep the PS2 in my bedroom, which is on the opposite side of the house to the network and desktop PC. Moving the modem  was not an option, and I already had a wireless network set up with my Laptop.

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. This is all good and well except that it requires a good 4 hours to charge the Shuffle from completely dead to completely full. If you're on the road this can be rather impractical. Thus, there was a need for a batterypack/charger device that can extend the usefulness of the Shuffle. Apple sells such a device but it is rather expensive for what it does. Granted it looks very nice, but I knew I could make the same product for less. And who can give up a chance to solder?
