Pete Taylor, over at Kimondo.com, has written up his project to create an old-fashioned Swingometer. The Swingometer at the moment does not track the General Election results (on account of us not having had the election yet!) but instead “scrapes” a…

Clusters and parallel programming with MPI and Raspberry Pi
Fabio Nelli has written an excellent tutorial on creating a cluster of Raspberry Pis (just two to start with) and using them to do some parallel programming. He uses the MPI library in Python to set-up communication between the two Pis. It’s…
Use your Kindle as a screen for the Raspberry Pi
This is not a new idea, but I’ve not seen the process documented as well before. Guillaume Levrier has written up his project that bonds a Kindle Paperwhite to the Raspberry Pi, allowing it to be used as a screen.…
Remote control Raspberry Pi GPIO with messaging queues
Messaging queues are all the rage nowadays, what with being the backbone for a lot of Internet of Things projects and concepts. In his blog post, Brian Hines explains how to use a library he wrote called pi-control-service together with RabbitMQ to…
Install Lazarus Pascal on a Raspberry Pi
Lazarus Pascal is a free Delphi look-a-like and compatible Pascal development environment based on FPC (Free Pascal Compiler). Hans Luijten from Tweaking4All.com has written a comprehensive tutorial on installing Lazarus on the Pi 2. He also includes instructions for installing it on other Raspberry…
Use an external drive to drive your Raspberry Pi
Over at Adafruit, Brennen Bearnes has written a great tutorial and helper script that will enable you to use an external drive as a “root partition”. This means that although your Pi still boots from the SD card, thereafter everything else…
Interfacing a VFD display to the Raspberry Pi
Dr Scott Baker has been messing around with VFDs (Vacuum Fluorescent Displays) which emit light directly rather than being backlit like normal LCD displays. He has worked out how to interface such a display with the Raspberry Pi and has…
Big Data on the Raspberry Pi 2
Newcastle-based Darren has written a tutorial that covers installing Apache Spark on the Raspberry Pi. Spark is a Scala library that is used for the analysis of so-called “big data”. This is the first in a series of posts and…
Limit SD Card writes on Rasberry Pi using Ramlog
It’s well-established that SD cards have a finite lifespan. This lifespan is dependent on the number of writes that you do to the card (although the number of reads is largely irrelevant). Alexander van der Sar has blogged about using a…
Low memory-usage blog platform for the Raspberry Pi
Andy Molenda has blogged about his experiences using Grav which is a low-memory footprint and highly efficient flat-file CMS. It has enabled him to run a blog on his 256MB Pi with very good performance. He has written up how to install…
