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 […]

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 robot Android app

Thursday, February 26th, 2015

I created a web front end for my Raspberry Pi based robot, which works well on a desktop PC, but not quite the way I wanted on a mobile phone. My idea was to have graphical buttons for the different directions and holding down the button will make it move in that direction and releasing […]

Energenie infrared socket and Raspberry Pi infrared

Thursday, January 22nd, 2015

I have already posted about the Energenie wireless remote control sockets. I’ve now had chance to look through one of their other products – which is an infrared remote control socket. This is a power saving socket allowing a TV and associated equipment to be fully powered off from the mains socket using the normal […]

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 […]

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 […]

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 […]
