My new book is now available. Learn Electronics with Raspberry Pi (2nd Edition). This is an update on my first book which is now over 4 years old.

Raspberry Pi Halloween Animated Light Display – RGB Matrix LED display with pumpkin and PIR sensor

Thursday, October 29th, 2020

My Raspberry Pi Halloween project for this year is based around the Raspberry Pi RGB matrix display project. I have put the RGB Matrix outside of my house and wanted to display a Halloween animation on the display. I also wanted to include a PIR sensor which changed the display when someone approached the display. […]

Arduino Vs Raspberry Pi – Microcontroller Vs Computer for maker projects

Monday, October 12th, 2020

In this video I look at some of the features of the Arduino and the Raspberry Pi to see which is the best fit for your project. Whilst it starts with the answer “it depends”, it gives scenarios where each is better and for those where either is a good fit I’ll give my own […]

Home automation light bulbs from Sengled

Wednesday, April 3rd, 2019

I have created some DIY home automation in the past. This was based around using remote control of mains electrical sockets (Home automation – controlling Energenie power sockets using a Raspberry Pi) but I also used a home automation light on one of my home lights. Since then the number of commercial home automation devices […]

Raspberry Pi Christmas Project – Christmas House and Neopixel Snowman

Monday, December 17th, 2018

This year I’ve been creating a 3D model of a building for an outdoor model railway. Technically it’s a building for a weigh bridge rather than a house, but I’ve given it a Santa’s Grotto make-over for Christmas and so Christmas House sounds better. The building is designed in TinkerCAD based on a real building […]

I’d therefore like to start by dispelling some of these myths and explaining what I think that model railways is about. The 3 Golden Rules of Model Railways Many people have come up with different rules for model railways, here’s […]

Raspberry Pi or Arduino NeoPixels (Smart RGB LEDs with ws281x)

Tuesday, August 28th, 2018

I’ve recently been having fun with some NeoPixels on the Raspberry Pi. NeoPixel is the name that Adafruit uses to refer to “Smart RGB LEDs with WS2811 / WS2812 integrated controllers”. I’m sure you’ll agree that NeoPixel has a better ring to it and as that’s the name of the Python library that I’m using. […]

I have been to the earlier birthday celebrations, supporting workshops run by others, giving presentations and running workshops. For 2018 the birthday celebrations […]

Review of MeArmPi robot arm for Raspberry Pi

I backed the MeArm Pi kickstarter project earlier this year, and just received the finished product. It’s a, laser cut, plastic robot arm which has a built-in Raspberry Pi. It is created by Mime Industries who have previously created a similar robot arm without the build-in controller / Raspberry Pi. It can be controlled using […]
