I first came across the BeagleBone when Roger Monk presented at OSHUG #18 in April 2012. It was easy at the time to write it off  as too expensive and too underpowered – the Raspberry Pi was finally shipping and the lucky first 2000 already had their $35 computers whilst the rest of us waited for […]


Two years ago I took my son along to Maker Faire UK in Newcastle (which is where I grew up). This year the whole family came along. Whilst I queued with the kids for the ‘laser caper'[1] my wife went along to a talk by Clive from the Raspberry Pi Team. I can’t blame her […]


In earlier posts of this series I’ve looked at ladder board and Quick2Wire’s boards. This post is about the official expansion project board for the Raspberry Pi, named after its creator Gert van Loo, the Gertboard.

I set $son0 a summer holiday challenge of building an alarm system that would send an email (and it seems that I’m not alone). I was pleased to see that the latest edition (#4) of Magpi has an alarm project so we set about building it together. The hardware came together pretty nicely, but the software […]
