Controlling electrical sockets with Energenie Pi-mote

Last Christmas I decided I had spent enough time bending over the various chairs to reach the switch to turn on and off the Christmas tree lights. So I bought a set of Energenie remote-controlled mains switches. I decided that this would be a great device to wire up to the Raspberry Pi, because I could... Continue reading

UK teachers: want two days of free, top-class CPD? Check out Picademy, and send us your applications! What do you get if you cross a PiFace with a rubber dinosaur from Marks and Spencer? Twitter magic, that’s what. Teacher Dan Aldred has come up with a thing of beauty: a hack that makes your desktop... Continue reading

Minecraft Pi recipe cards to download and keep

We think Craig Richardson’s brilliant. His Python Programming for Raspberry Pi book (available as a free download) remains one of the very best tools for stealthily teaching rigorous and useful computing concepts and programming tricks to kids that we’ve seen. Kids love Craig’s resources (we’ve found it hard to make them stop working and pack up to go home when... Continue reading

Mudra: a Braille dicta-teacher

Sanskriti Dawle and Aman Srivastav are second-year students at the Birla Institute of Technology and Science in Goa. After a Raspberry Pi workshop they decided they wanted to do something more meaningful than just flash LEDs on and off, and set this month’s PyCon in Montreal as their deadline. They ended up producing something really... Continue reading

Learning Python with Raspberry Pi

If you’ve been round here for any length of time, you’ve probably heard mention of Alex Bradbury. Alex is currently polishing off his PhD thesis at the Computer Lab at the University of Cambridge, and he’s been involved with the Raspberry Pi project as a volunteer from our very early days, back when all we...

Raspberry Pi Projects: a big book by Andrew Robinson and Mike Cook

Ben here – Liz is currently non-functional due to her body having no idea what time it was when she arrived at the office this morning after landing back from San Francisco at the weekend. Raspberry Pi Projects is a fantastic book from Wiley, the publishers of Eben and Gareth’s Raspberry Pi User Guide and Carrie Anne’s Adventures... Continue reading

Graphic equaliser

Our good friends at Adafruit put this project on their Learning System earlier this month. It’s a beaut: you’ll learn something making it, and it looks fantastic when set up. Before we get into the nitty gritty, here’s some video: This graphic equaliser (a spectrum analys/zer if you’re from the USA) is made from a... Continue reading

A pure Python interface for the camera module: meet picamera!

If you have a Raspberry Pi camera module, you’ve probably used raspistill and raspivid, which are command line tools for using the camera. Dave Jones, a Database Admin, software developer and SQL know-it-all based in Manchester has been working on an equivalent, feature complete implementation of these in Python. This means you can access the... Continue reading

PyPy 2.1 beta released

Back in May, we mentioned that we’d been sponsoring the development of the ARM port of PyPy, the high-performance Python interpreter. Earlier today the team released a first beta of the upcoming 2.1 release, which for the first time adds ARM as an officially supported architecture. You can see the announcement here, and download binaries... Continue reading

PyPy on Pi

While we love all programming languages equally here at the Foundation, we do love Python an awful lot. Most users run their code under the “default” CPython interpreter, but over the last few years the PyPy project has made great strides in producing an highly compatible alternative interpreter with an integrated tracing JIT compiler. On... Continue reading
