Potato-Powered Web Server

It's no longer running on potatoes, but a single AAA battery which they say will last several years. Freakin' cool nonetheless.

This is an actual potato-powered Web server, currently online here. After the great SpudServer joke, I thought it would be interesting to see what an actual server capable of running on potatoes would look like. This server is very, very slow (around 0.2 hits/second), so you may have trouble connecting.

The CPU is a Microchip PIC16F876 running with a 76.8 KHz clock and a nominal 1.5V supply voltage (somewhat outside the manufacturer's specifications). At this speed and voltage, it draws 20 microWatts (0.00002 Watts), or roughly 100,000th to 1 millionth the power of any Intel 386 board I know of. It connects via SLIP at 4800 baud.
