Raspberry Pi Roundup featuring an electronic name badge, a Node-RED starter tutorial and a Zero in an Altoids tin!
Electronic Name Badge
Josh King has taken a Raspberry Pi Zero, a PaPiRus 2″ e-ink HAT, an Adafruit Powerboost 1000c and a LiPo battery and made himself a name badge. He’s written the whole thing up as an Instructable which you can read here.
I’ve just spotted this new resource on the Raspberry Pi website’s resources section. It shows you how to get started with controlling the Raspberry Pi’s GPIO pins using visual programming language Node-RED. It’s a nice tutorial and helps you get your head round some of the intricacies of the language and how to configure it to work with the GPIO. Read it here. Shameless plug: If you’re after the components to do the tutorial, you can do worse than getting the £5 CamJam EduKit from The Pi Hut.
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. He just needs to add an RF dongle in now to allow him to program with a keyboard!
