High altitude ballooning with the Raspberry Pi and Lego figures

Wednesday, October 7th, 2015

We visited the education day on PyconUK again this year (read about last years PyconUK Kids education day). It’s a great day for children to get excited about programming and this year electronics as well. Another new feature of this years education track is that the Raspberry Pi education Skycademy team launched high altitude balloons […]

Review of Meccano Meccanoid G15KS educational personal robot

Saturday, September 5th, 2015

Introduction This is a review of the Meccanoid G15K personal robot from Meccano. It’s a programmable robot that’s about 4 feet tall (about the same size as a 6 year old child). The recommended minimum age is 10 which I believe is the age for making it; I’m hoping to use it to teach programming […]

Raspberry Pi St George’s day with Unicorn Hat

Thursday, April 23rd, 2015

I’ve recently bought a Pimoroni Unicorn Hat for my daughter to use on her Raspberry Pi. It’s a add-on for the Raspberry Pi which provides 64 LEDs each of which can be individually set to any colour. As it’s St George’s day I’ve created a St George’s cross. The photo is shown through a diffuser […]

Raspberry Pi 2 – New 1GB quad-core $35 computer

Wednesday, February 4th, 2015

The Raspberry Pi is a $35 computer designed to provide a platform for children to learn computer programming. The Raspberry Pi was launched in 2012 and became and immediate success, with the only problem being how to satisfy demand when initial orders exceeded everyone’s wildest dreams. Initially many were bought by adult makers rather than […]

Adding a home disk to virtualbox virtual machine – Ubuntu VM

Monday, January 26th, 2015

Introduction Recently I ran out of space when using a Virtualbox virtual machine. Normally I use a dynamic disk that allows resizing (typically setting it to be much larger than I expect to use), but in this case I am using a virtual disk provided for me. It’s based on VMDK and Virtualbox does not […]

Git – Version Control that’s addictive

Tuesday, January 20th, 2015

Git is a version control system. A way of keeping regular backups of files which is particularly useful for creating computer source code. I’ve used other version control systems before (CVS and Subversion) and other tools that provide an element of version control (eg. Dropbox), but so far I’ve only really used them when I […]

Changing from RaspBMC to OSMC – static IP address and remote connection

Monday, January 5th, 2015

I’ve been running XBMC using RaspBMC on a Raspberry Pi for some time. I’ve digitised my music and videos and this allows me to watch them on various TVs around the home accessing from a central server PC. Recently the XBMC project has now renamed itself as Kodi to reflect that it has changed from […]

Installing a MyPiFi LCD onto a Raspberry Pi in a Pimoroni Pibow case

Wednesday, December 10th, 2014

Having already done some work with LCD displays on the Arduino I had been looking for a project to use one with the Raspberry Pi. Wiring this up was a bit messy until the MyPiFi LCD display board came along. The problem I then had was that I couldn’t fit the MyPiFi LCD onto the […]

Going Sober for October – What is it really about?

Wednesday, October 15th, 2014

Last time I wrote about my Going Sober for October challenge it was pretty much about what I was doing, but this time it’s more about why I’m doing this and the charity that I’m raising money for. I’d certainly heard about Macmillan Cancer Support charity and particularly about the Macmillan nurses, but I’ve not […]

Go Sober for October – raising money for Macmillan cancer support

Thursday, October 9th, 2014

For the month of October I’m giving up drinking alcohol as part of the Macmillan Go Sober for October campaign. It’s been a week now and it’s going well. I don’t normally drink too much, but I do enjoy drinks especially with certain meals or when going out. I’ve therefore been swapping my drinks for […]
