Raspberry Pi Motion Triggered Halloween Pumpkin Jack-O’-Lantern

Sunday, October 23rd, 2016

My 8 year old son has now completed another Raspberry Pi project. This project is a Halloween Pumpkin, or jack-o’-lantern, which is triggered whenever someone comes near. It uses a PIR motion sensor to detect someone entering the room and then lights up a sequence of NeoPixels. In this case these are static green and […]

Sunday, November 29th, 2015

The Raspberry Pi foundation has made a new Raspberry Pi computer called the PiZero.

Not only that but they are so inexpensive they’ve been […]

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 […]

Although the B+ was released before the screens actually shipped for logistics reasons (and to reduce […]

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 […]

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 […]
