Rasmus Hauschild from Denmark was 14 years old when I previously featured another build of his on the blog. This time he has gone small with a 3D-printed Gameboy case running RetroPie called Pi Zero Gameboy Nano. Inside is a Raspberry Pi Zero. You can print and assemble your own by downloading the files from Thingiverse or you can buy one customised to your requirements for $250 direct from Rasmus.
Jasper Ruben built his cats a ‘hamster wheel’ for exercise and just for general cat-happiness-quotient. He’s connected up some sensors to it and these feed data back to the Raspberry Pi which calculates speed and distance travelled. A gallery of how he built it is available as is a gallery of when he added the sensors and Pi and here is a Reddit thread if you’d like to ask questions or leave comments.
Jeff Geerling has discovered in his work on the Raspberry Pi Dramble cluster that Raspbian Jessie does networking a bit differently. Whereas before (with Wheezy) it was just a case of adding some lines to /etc/network/interfaces, now you need to add some lines to /etc/dhcpcd.conf to make dhcpcd5 set the static IP address. More details here.
Dum dum dum dum-de-dum dum-de-dum.
Leon Anavi has written an Instructable tutorial in which he takes a simple piezo buzzer, connects it up to his Pi and then uses C/wiringPi to play John Williams’ Imperial March. You can read the Instructable here.
