Making a splash by being introduced to the world at Foo camp is the hardware hacker friendly Chumby. The Chumby can most easily be described as a glorified alarm clock, kind of. It is really a little wi-fi device onto which you can load various gadgets that are obtained from the net. It will then display whatever widgets you've configured it to use. Some of the (free) widgets include an alarm clock, weather, news, movies and even stock tickers.
As far as it's insides are concerned, I found a pretty good description here
Chumby runs on a a 266MHz ARM controller, with 32MB SDRAM running at 133MHz bus speed and a six-layer board. The touchscreen is a 3.5" TFT LCD with LED backlighting, and an ambient light sensor tells chumby when to dim its backlighting. There are stereo speakers, a headphone jack, and a power supply that can use between 6 and 14 volts. A squeeze sensor allows users to open up the case after it's been nestled inside its soft, Tribble-like shell.
Nice. The makers of the Chumby want the so inclined to be able to hack away at the Chumby's innards without it being that much of a pain. So while those specs listed above is what the Chumby will ship with, you're definitely not stuck with that configuration. If the Chumby takes off, there will probalby various resources you could to go for instructions on how to hack it into something you may find even more useful.
