A great site

For those of you that like the interesting world of hacking, here is a site dedicated to hacking EVERYTHING from coke and pepsi machines to laser pens.

Transmit Audio with a Laser Pen
Using a simple laser pen pointer, a few misc parts, and about 15 minutes, you can make a simple laser communicator that converts a sound source into light that travels across a room, and back into sound with very little quality loss.

Using the hidden browser on the Sony PSP
If you haven't heard, there's a "hidden" web browser in the PSP! Apparently Sony built the functionality in but haven't released a web browser that we can use yet. However, there's one game that actually uses this browser, and with a little trickery we can take over and do whatever we want. The game is Wipeout Pure, a great game in its own right, but made even better by the fact that it lets us get to the PSP Browser (called the PSP Navigator according to the User Agent it reports itself as).
