In the pantheon of geek projects there are few things as potent as the creation of an FTP server. Rather than doing cool stuff like serving up web pages or handling phone calls, an FTP server just sits there serving up files like a Michelin-starred chef slinging hash at a diner. But what if you made it solar-powered? What then?
Well, you get the crazy sort of DIY project I love to see. This thing is basically a 3D-printed case with a battery pack/charger combo run by sunlight and a Raspberry Pi set up as an FTP server. This means you could, feasibly, run this FTP server forever given enough light.
The full instructions are on CNet but you can get the solar panels here and this includes a 3D-printed case that can hold the Pi and some rechargeable batteries. You could, feasibly, make the Raspberry Pi do anything but it seems to me an immortal FTP server that could potentially send out data until the sun-death of the universe could be a nice homage to mankind’s struggle for relevancy.
