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 […]

HDMI Pi – Raspberry Pi screen – upgrade to Raspberry Pi 2 / B+

Monday, April 6th, 2015

When the Kickstarter was run then there were only the model A and model B Raspberry Pi computers and the screen was designed for the model B. Although the B+ was released before the screens actually shipped for logistics reasons (and to reduce […]

Monday, March 16th, 2015

The Big Bang fair is a free STEM (Science, Technology, Engineering and Maths) event aimed at children aged from 7 to 19. It’s an annual event and I first attended the Big Bang Science Fair last year – Big Bang Fair 2014. I took my 8 year old daughter (now 9 year old) along and […]

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 […]

Raspberry Pi – Heart beat – 8×8 LED display with I2C BackPack from AdaFruit

Thursday, February 5th, 2015

This is based on the AdaFruit 8×8 Bicolor LED display with I2C BackPack. It’s connected to a Raspberry Pi 2, although it’s only very simple and could be connected to any model Raspberry Pi. After soldering the parts together (checking that the display is the right way round – with the writing near the round […]
