Build your own digital clock with a Raspberry Pi with this Kickstarter
David Saul is running a Kickstarter campaign to fund a new add-on board for the Raspberry Pi. Compatible with the B+, A+ and Pi 2, the PiMuxClock plugs into the 40-way GPIO header and stands up, giving you a large…
Interfacing a VFD display to the Raspberry Pi
Dr Scott Baker has been messing around with VFDs (Vacuum Fluorescent Displays) which emit light directly rather than being backlit like normal LCD displays. He has worked out how to interface such a display with the Raspberry Pi and has…
Raspberry Pi iBeacon system for bypassing theme park queues
Hacker (and fellow amateur thesp) Michael duPont attended a hackathon at Universal Studios in March and helped to create a system whereby guests to the theme park could bypass ride queues by visiting certain checkpoints in a park area, thus completing ‘challenges’. This…
Raspberry Pi web server using Python/Flask
Here’s a good Instructable on getting your Pi set-up to act as a web server. It uses Python and a library called Flask in a script which creates the server on-the-fly. This is an excellent introduction to Flask which can…
Raspberry Pi voice translator via Google and Microsoft
Wolf Paulus has taken his work on speech recognition further and has hooked up the recognition text received from Google Translate to the free Microsoft Azure translation service. He now has a Pi-powered voice translator! Read about it and watch a…
Using the PiStop with Scratch on the Raspberry Pi
Teacher Cat Lamin has written up a quick sort-of review of the brilliant PiStop from 4tronix. This simple little GPIO plug in board gives you access to some traffic light LEDs that you then program using your favourite language on the…
Graphical plot of Raspberry Pi load averages
Eric, a self-confessed beginner with Raspberry Pi, is using Python’s matplotlib library to plot data. In this code example, he uses the library to plot the Pi’s 1-minute load average on a line graph. See the code here.
Raspberry Pi NFC Minecraft blocks
Tony Dicola has written a great tutorial over on the Adafruit site in which he uses an NFC reader and tags together with a Raspberry Pi running Minecraft. The scripts he has written allows you to program different NFC tags…
BerryIMU sensor for Raspberry Pi gets Python library
A little while ago, I backed a Kickstarter campaign to fund the development of the BerryIMU. It’s a (very) small board that gives you access to a gyroscope, magnetometer, accelerometer, pressure/altitude sensor and temperature sensor through the I2C protocol. Mark…
