Yes, this website
is was running on a $35 Raspberry Pi! A Pi is a small (a little bigger than a credit card), single board computer that runs Linux. I had an extra Pi and thought that this would be a good use for it.
Update – I ran the site for about 6 months or so on the Pi. I would have to reboot it or restart apache about once a week. I needed the Pi for another project so I moved the site to another computer.
