Matt Wagner has taken a Raspberry Pi Zero, a RedBear IoT HAT for wifi connectivity, a 2″ Adafruit screen and some power circuitry and fitted everything into an Altoids Tin, thus creating a portable Pi workstation. It’s even got a power switch, which is handy as it stops the battery discharging. His first version included a camera module, but the addition of the LiPo battery meant that had to go for the final version. He’s written the whole thing up as a tutorial, so head over to his blog to read all about it. Just needs to add an RF dongle in now to allow him to program with a keyboard!
