GrovePi Zero – a Raspberry Pi sensor playground – review and sample project
Jamie Bailey’s been in touch. Over at Initial State, they’ve been playing around with the GrovePi Zero by Dexter Industries. It’s an add-on board that plugs into the Zero’s GPIO pins and gives you the ability to use Grove sensors, as…
Using Python to estimate your vocabulary – practical programming produces perfect picture
Alex Eames has been rediscovering the joy of practical programming and has come up with a great Python tutorial. The tutorial investigates the level of your vocabulary by importing a list of words and asking you whether you know what…
A make-it-yourself touch-capacitive kit for the Raspberry Pi from PiCymru
Doug Gore and the PiCymru team have developed a new kit that turns common objects into touch capacitive devices and then feeds the input signals back into the Raspberry Pi. It’s called PiFun and is inspired by MakeyMakey. The kit, which is available…
Build a compact GPS logger with a Raspberry Pi Zero
Here’s a good one from Instructables’ user Postron. He’s taken a Pi Zero, an Adafruit GPS module, an Adafruit LiPo power board and a LiPo then constructed a circuit with buttons and resistors on prototyping board to create a portable…
Powering your Raspberry Pi from a LiPo the right way
Powering a Raspberry Pi from a LiPo battery isn’t a piece of cake. Fortunately, a couple of expert hackers have done the work for you by writing up the methods. Building on Daniel Bull’s work to power a Raspberry Pi from a…
Flashing the new Raspbian image onto a Raspberry Pi’s SD card
The new Raspbian image is over 4GB. This introduces some challenges when trying to write it to an SD card. In particular, unzipping it on Windows and Mac using their built-in tools will fail because they’re a bit naff. Alex…
Creating simple GUIs with EasyGUI on the Raspberry Pi
Richard Saville has been looking at GUI libraries for the Pi. He’s found EasyGUI which is very useful if you want to create something basic. There are better libraries out there that do more, but having seen the code, it’s very easy…
Build a Gibsonian cyberdeck from a Raspberry Pi and a Commodore 64
D10D3 on Imgur (and Twitter) has taken an old (non-functioning) Commodore 64, a Raspberry Pi 3, various connectors and some custom-fabricated bits and pieces and created his very own version of the Ono-Sendai Cyberspace 7 cyberdeck from cyberpunk author William Gibson’s Sprawl…
Turn your Raspberry Pi Zero into a USB plug-in dongle
Hacker NODE has worked out that if you solder a full-sized USB male connector to the data USB pads and power/ground lines on a Raspberry Pi Zero, you can just plug the Zero into your PC like a dongle and…
