Need a truly portable Linux computer? Over on NODE, Chris Robinson shows how build a Linux-powered computer inside a USB charger for ultimate portability.
Once you get this set up, all you need to do is plug it into the wall. You can set it up as a TOR relay, a media server, a personal VPN, or whatever else you want to use a Linux machine for.
The guts are made from an ODROID-W development board, which is compatible with the Raspberry Pi and Raspbian. You’ll also need a USB charger, a Wi-Fi adaptor, a micro SD card, and a few other materials to build everything.
Putting everything together isn’t crazy complicated, but you will need to do some soldering, and since you’ll be working with electrical components it’s important to follow Robinson’s guide closely.
