Introduction Hi everyone. I recently took part in an episode of The Pi Cast from Tom’s Hardware during which I presented my latest project: a Mini (or Tiny!) Raspberry Pi Cyberdeck. You can see the full episode below. Of particular…

The PicoPicorder – a work-in-progress prototype using a Raspberry Pi Pico and lots of components from Pimoroni and Adafruit!
During March, and for the past week as well, I’ve been working on the latest iteration of my Picorder project. This project, which has been my “go-to project” for the past 9 years (gulp!) is now running from a Raspberry…
Raspberry Pi Big Birthday Weekend #PiParty – videos of talks
David Ferguson attended the Raspberry Pi Big Birthday Weekend (Pi Party) this year and recorded many of the talks taking place in the auditorium. He’s uploaded all the videos to YouTube, and listed a couple of others by Alan O’Donohue,…
Picorder (version 10) gets a walk-through construction video #RaspberryPi
My Picorder has reached another version. This time it’s got a proper case and lots more sensors. With the help of Amanda, my step-daughter, we shot this putting-it-together video that shows all the parts and bits-and-pieces that go into the…
Experimenting with the Easy Pulse and #RaspberryPi
As part of my Picorder project, I bought an Easy Pulse from Embedded Lab (via Elecrow). It’s a red PCB with a plugin fingertip sensor (see above). The example code you can download is in C and my Picorder code is in…
Cheap-as-chips ultrasonic SR04 distance sensor – #RaspberryPi compatible
I’ve just been browsing a little (waiting for the coffee to kick in!) and come across some SR04 distance sensor modules at Hobby Components. These are ridiculously cheap at £1.75 (inc VAT) and are very close in price to those…
I2C 20×4 LCD character display on a #RaspberryPi
Take a look at this more up-to-date post which uses a Python library to do the necessary. I bought this display from Hobby Components: It is very similar to the Sainsmart 2004 LCD display and the pin mappings are the…
Geiger counter breakout board under development for the #RaspberryPi
Hackerspace group Apollo NG are developing a new board for the Raspberry Pi which houses a Geiger counter. They’re in development at the moment and you can indicate a preference for how you might like to get hold of the…
The RaspberryPi Tricorder – the Picorder
This project has been in progress since I first received my Raspberry Pi last July. Until now, I just haven’t had the time to record video. The Picorder is a Pi/Arduino combination taking readings from 2 temperature sensors, a hall-effect…
Using a HMC5883L magnetometer/compass with the #RaspberryPi
This blog post describes getting an HMC5883L magnetic compass sensor to work with a Raspberry Pi. The pictures below show the sensor breakout board in question. For Arduino Leonardo If you do not have an Arduino, or just want the…
