Check out this cool device that can monitor a cat’s water dish and also twits it to Twitter.
1. Arduino waits for serial communication from computer connected by USB. Upon request from the computer, it will take a water level reading and send it back. 2. The computer, an NSLU2 reflashed with Debian, sends a request every hour at “0″ minute for the current water level. It takes that level and creates a text file, the text file is then uploaded to t
It looks like someone very smart figured out how to use your PSP as a status monitor. Of course, I am sure you can customize this to per say, monitor your web server such as this one. More PSP hacks here.
