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 […]

SPAM pretending to come from watkissonline.co.uk

Wednesday, September 10th, 2014

I have received reports that a spammer is sending emails requesting payment for an invoice from watkissonline. I can assure you that these are SPAM emails that are not from watkissonline, but appear to be originating from a server in Africa. If you receive an invoice email please delete it. I have added SPF authentication […]

Turn a wet bank holiday into a fun science day

Monday, August 25th, 2014

We had a very wet public holiday today. Whilst there are some indoor days out we could have gone to we instead decided to have a science day at home. The two main things we did today were to make a cola can cable car and an erupting volcano. The cable car comes in a […]

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 […]
