Review of CamJam EduKit 3 Robotics by Cat Lamin
Cat Lamin is a primary school teacher (and Raspberry Pi Certified Educator) and has recently got hold of CamJam EduKit 3 Robotics. The kit is a collection of electronic components that will help you get started with robotics using the Raspberry Pi and…
Run a network stack over Bluetooth on the Raspberry Pi 3
By now, of course, everyone knows that the new Raspberry Pi 3 includes Bluetooth capability. Andrew Mulholland has made a video that shows you how to run a full network stack via Bluetooth using his Mac. If anyone can get…
Increase the range and quality of your Raspberry Pi 3 wifi
Ward, from DorkbotPDX, has tried out two concepts for increasing the range and quality of his Raspberry Pi 3 wifi connection. I should point out straight away: this hack voids your warranty and FCC certification, and the soldering is a bit…
Play the Imperial March from Star Wars using a Raspberry Pi and a piezo buzzer
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.…
Tiny Gameboy-style device with a Raspberry Pi Zero inside
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…
Giant running wheel for cats uses Raspberry Pi for measurements
http://i.imgur.com/Oh2YlGa.webm 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…
Setting a static IP address on the Raspberry Pi running Jessie Lite
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…
Creating electronic music on the Raspberry Pi
Everyone’s heard of Sonic Pi, the programmer’s method of producing music on the Pi. Seth Kenlon wanted to use the Pi to produce electronic music the more traditional way – by using synths, trackers and other software in combination. You…
Raspberry Pi-based Braille e-book reader prototype
Bristol Braille Technology is working on a more affordable replacement for traditional Braille reading machines. Under the hood is a Raspberry Pi running C and Python, controlling off-the-shelf motors and plastic gears to create the Braille text. Traditionally, Braille machines can…
