The Raspberry Pi $5 PiZero – the cost is only half the story

Sunday, November 29th, 2015

The Raspberry Pi foundation has made a new Raspberry Pi computer called the PiZero. It’s a smaller version of the version 1 Raspberry Pi that’s been stripped back to the bare essentials with price that’s an amazing $5 (currently £4 in the UK including VAT). Not only that but they are so inexpensive they’ve been […]

When it’s time to re-install Ubuntu / Kubuntu Linux

Tuesday, November 17th, 2015

One of the benefits of a Debian based Linux operating system is how easy it is to upgrade. In the case of Ubuntu and the KDE version Kubuntu then there is a new release every 6 months providing. This provides a way to get the latest versions of all the software with minimal fuss. For […]

Fixing erratic Clickpad / Touchpad behaviour on Dell Inspiron 7000 series with Kubuntu / Ubuntu 15.10

Friday, November 6th, 2015

I have a Dell laptop – Dell Inspiron 17 model 7737 When I first bought it I installed Ubuntu 13.10, which worked well with a little tweaking of the clickpad settings. More details about installing Ubuntu Linux on the Dell model 7000 series are available here. Since then I’ve moved to Kubuntu (based on Ubuntu […]

Next generation innovators at Malvern Festival of Innovation

Tuesday, October 20th, 2015

I recently spent a day at the Malvern Festival of Innovation – introducing pupils to physical computing and computer programming. The event was in co-operation with STEMNet (who arrange the background checks and provide support) and The Institute of Engineering and Technology (IET) (who provided all the materials and equipment on the day). The event […]

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 […]

Computers and robots – Digital Maker Badge with Beaver Scouts

Monday, October 5th, 2015

The Scouts have introduced some new staged activity badges which provide different levels of achievement. One of the new ones they’ve added is the Digital Maker which is all about using making games, programs and robots. The highest stage goes as far as making their own robot using off-the-shelf components, but I was working with […]

Robot Arm control software for the Raspberry Pi

Friday, September 18th, 2015

Frustrated by the lack of Linux support for an education Robot Arm I bought – I’ve written my own. Other community members had already worked out the code to allow you to program the robot arm yourself in Python, but I wanted something that young children could easily see and interact with. I have therefore […]

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 […]

Neopixel GUI for the Raspberry Pi

Friday, May 1st, 2015

I’ve started work on a graphical application to control Neopixels using the Raspberry Pi. This is one of my first projects using Python and Tkinter. It’s primarily designed for a disco DJ environment where a DJ may want to change the LED sequence based on the music being played. It uses nice big buttons (ideal […]

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 […]
