Build an IoT connected alarm clock with London Bus arrival times
In this tutorial, we’ll be building a smart ‘Internet of Things’ (IoT) connected alarm clock with a Raspberry Pi, that continuously monitors bus arrival times, and delays your alarm accordingly to give you the maximum amount of sleep! Read on below to find out how to put together this fantastic project!
Connect to Adafruit’s Huzzah ESP8266 using only a Raspberry Pi
Here’s a quick tip showing you how you can connect to Adafruit’s HUZZAH ESP8266 breakout board using only a Raspberry Pi! Read on below to find out how!
MAX7219 LED Matrix GUI controller and Python library
LED matrices are quite popular amongst makers these days, but being able to upload a cool 8×8 graphic to show on your matrix can be cumbersome. In this post, I detail a great Python library I’ve written allowing you to control the matrix using buttons in a GUI, coded using the brilliant PyQt4 module. If […]
London Underground line status with Neopixels
In this quick tutorial, we’ll put together a snazzy London Underground tube line status checker using a Raspberry Pi and Adafruit’s awesome Neopixel LED rings, to recreate the classic Underground roundel! We’ll light up the Neopixel LEDs using the official colours of the Tube lines, allowing you to cycle through your favourite tube lines and […]
Neopixel LED controller with Arduino
If you’ve been reading my blog, you’ll know I recently got my hands on an Arduino, which means learning a new programming language, C! After playing around for a couple of weeks and getting to grips with the language, I put together a nice little project which I thought would make a great tutorial! This […]
Arduino vs Raspberry Pi comparison
A month or more ago, I finally decided to try my hands at the Arduino, and got my hands on an Arduino Uno-based board from Hobby Components. These are cheaper clones of the original Arduino board, made possible since the actual design for an Arduino board is Open source. Unfortunately, a few weeks later, the dispute […]
Touch free water dispenser with a Raspberry Pi
It’s a been a while since I’ve been able to post on my blog, as I’ve been quite busy lately with work in lab. But that doesn’t mean I haven’t been thinking of posts, so here’s a quick tutorial I’ve been planning since weeks, but haven’t had time to write up!
Buffer and solution pH adjuster with Raspberry Pi
Ever since I got my hands on a Raspberry Pi, I’ve been meaning to do a real science oriented project with it. Not just a little project that you can have fun with for a while, but an actual practical and useful project. I tried Googling for any similar ideas online, but unfortunately, I didn’t really […]
Neopixel LED temperature gauge with Raspberry Pi
In this tutorial we’ll be creating a circular temperature gauge using Adafruit’s Neopixel LEDs, a Raspberry Pi and components from Monk Makes Starter Kit! No Arduino required! And to make it even more better, we’ll be using Plot.ly to plot the data in real time, turning this little project into an Internet of Things (IoT) […]
DNA flashing LED box with a Raspberry Pi
Learn how to create a flashing LED box that reads a DNA sequence and flashes a different colour according to one of the four DNA nucleotides. You’ll need a Raspberry Pi (any model will do), an RGB led, three resistors and jumper wires (and breadboard) to wire it all up together!
