“willseph” was fed up with the amount of space, and the relative cost, of using netbooks to check tickets at his company’s events.

It looks very simple to put together and is clearly aimed at beginners who want to learn some new skills.
Prices start at £5 for the board kit and are available on the Kickstarter page.
LinuxGizmos.com has done a nice feature on two new add-on boards for the Pi. The first is Mikronauts’ RoboPi robot controller board and the second is the Emlid Navio which is used for auto-piloting drones. Read their coverage here.
