If you didn’t know, Raspberry Pi is very small sized, cheap, low power ARM computer. I won’t write more about this – you can read it on official page. So Wednesday I wanted to go shopping and I remembered my Pi is on the way (I’ve got email informing about it), so I looked into mailbox and almost screamed… I gave up on shopping and started hacking.
In the video above – LED diode changes color depending on system load. Green for less than 20%, blue for less than 50%, red for more.
