Build a Raspberry Pi Zero into a USB hub
Adding USB ports to the Raspberry Pi Zero seems to be a common occurrence nowadays, so I’ve not covered many of them on the blog. However, here’s a rather novel idea: taking a USB hub and fitting a Zero into it.…
iPhone game played automatically with a Raspberry Pi and a Gertbot
Junya Sakamoto wanted a little help with the later levels of Puzzle & Dragons (which is big in Japan). So he added a Gertbot to his Raspberry Pi and then hooked up some motors and a rig to allow the Pi to…
Portable Raspberry Pi Geiger counter
Jeff Cartwright has put together a lovely Instructable for creating a portable Geiger counter using a Raspberry Pi. He’s used a MightyOhm Geiger Counter kit, which communicates over serial to the Pi, added a PiTFT to display things on and then fashioned a…
Remotely-operated underwater drone controlled by a Raspberry Pi
Niels Affourtit has put together a brilliant project, one of my personal ‘holy grails’ – a submersible drone controlled by a Raspberry Pi. He put the Pi together with some 3D printed parts, some sensors and an HD camera. According…
Add low-profile wi-fi to your Raspberry Pi Zero
Adding wi-fi to your Zero has been done before but this is a really nice video, so I thought I’d feature it. NODE has taken the innards of a wifi dongle, some thin wires and a Pi Zero. He’s then soldered the…
Use bar graph displays with the Raspberry Pi
Average Man has written a great tutorial on using these tiny bar graph displays with the Pi. There’s a lot of wiring involved, and a lot of maths, but he takes you through it. He’s also written some code to…
Building a massive cricket scoreboard on a shoestring budget with a Raspberry Pi
A bunch of amateur hackers from Gloucestershire have created a digital scoreboard for their cricket club using a Raspberry Pi. The Pi acts as the master controller for an Arduino which controls the 7-segment displays. The interface is then accessed…
Fading LEDs using PWM with GPIO Zero on the Raspberry Pi
The project GPIO Zero, the new GPIO library from the Raspberry Pi Foundation, is becoming my go-to method for doing simple things with the Pi’s GPIO pins. Over the past couple of weeks, I’ve been having fun preparing for the…
Four-track audio looper with a Raspberry Pi
Szymon Kaliski has put together a Raspberry Pi, some buttons and potentiometers and a lot of circuitry to build a four-track audio looper. You can record four eight-second loops and then adjust their playback with the buttons and potentiometers to achieve the…
