One bricked phone and lots of reboots – I finally have Android Lollipop on my Nexus 4

Friday, November 28th, 2014

I have been a fan of Android since I had my first mobile phone. Since Gingerbread I’ve managed to have every new version (although still running an older version on some of my devices) and it just keeps getting better. So I was very excited when I heard that the latest version Lollipop was available […]

Halloween Scary Pi-Ano – Raspberry Pi and Makey Makey keyboard

Friday, October 31st, 2014

This Halloween I created an indoor halloween light effect using a Raspberry Pi and a PIR sensor. Unlike previous years my children weren’t really involved in making this one, which is because my 9 year old daughter decided to create her own Raspberry Pi based Halloween Project. She has created a Raspberry Pi, Makey Makey […]

Safely controlling mains electricity using the Raspberry Pi and Energenie Pi-mote

Sunday, October 26th, 2014

It’s useful to be able to turn mains electricity on using a computer program. Whilst it’s not hard to create an electronic circuit that can switch mains voltages, if not done correctly it can be dangerous. This is where the remote control sockets can be used to create a physical barrier between the low voltage […]

Book – Mastering the Raspberry Pi

Tuesday, October 14th, 2014

This is the second book that I’ve been the technical book reviewer for, the first being Learn Raspberry Pi with Linux. When I was contacted by Apress to ask if I’d do the review then I didn’t hesitate to say yes as from the description this sounded like just the sort of book I would […]

Malvern Festival of Innovation school’s day

Friday, October 3rd, 2014

It’s not often that you see a Raspberry Pi workshop, a team from (soon to be???) the worlds fastest car and some llamas in the same room, but that’s what you’d find at this years school’s day at the Malvern Festival of Innovation. I was there as a STEM Ambassador helping out on the Raspberry […]

Kids education day at PyconUK 2014

Wednesday, September 24th, 2014

PyCon UK is the UK conference for the Python programming language, held annually at Coventry. PyconUK is attended by many professional developers, but has recently added an education day to the line up. Last year was the first day that kids were specifically invited through the PyCon UK Raspberry Jam. For 2014 this evolved into […]

HDMI Pi – 9 inch screen for the Raspberry Pi

Monday, September 22nd, 2014

The HDMI Pi screen for the Raspberry Pi has now been made and is shipping to the kickstart supporters. It’s been a long wait, although much of that is due to changes and improvements in the design and we’ve been kept informed about the progress. So was it worth it ? … Yes! The final […]

Adding thumbnail images to MP3 tags for Citroen C4 Picasso USB MP3 player

Tuesday, September 16th, 2014

I have recently got a new car with a full graphical entertainment system. It’s a new Citroen C4 Grand Picasso with a built in Touch Drive system which includes a USB MP3 player. The system includes a 7″ touch screen which can display MP3 thumbnails. My CD collection is already digitized and includes JPEG cover […]

Bletchley Park and The National Museum of Computing

Thursday, September 4th, 2014

During the second world war Bletchley Park was home to the Government Code and Cypher School and played a critical role deciphering encrypted messages. I first visited a several years ago before it was opened to the public, it seamed a shame then that such an important part of British history wasn’t more accessible. Since […]

Unglue.it books – a new way of reading

Wednesday, August 13th, 2014

I’ve written before about my dislike of DRM, especially on ebooks (The problem with DRM on ebooks). Another thing that is great is when you can get a book for free, but with the option to reward the author by giving a donation. This is what I’ve done with a series of books called The […]
