Chris Crumpacker has been experimenting with a cute 3×4 matrix keypad: He’s got it working not only with just the GPIO pins, but also with a port expander, thus saving a lot of pins. The whole blog post, including Python…

One to keep an eye on – #RaspberryPi drivers from Whaleygeek
David Whale has just posted up a couple of placeholders on his blog for various drivers he’s hoping to develop. The first one (and again, still a placeholder at this point) is for a cheap RFID reader. Take a look here…
Adjust the sound volume of your #RaspberryPi via the command line
Netherlands-based Ed has created a script which wraps around amixer to allow you to specify volume as a percentage, or to increment/decrement the volume, very easily. Look at the script here
GPS Logger for the #RaspberryPi
A blogger on Tweetypi.co.uk has written about how to log GPS coordinates into sqlite3. I’ve decided to integrate this with the Picorder so I thought I’d give them a shout out! Read the blog post or view the code on Github.
Simple two-way NFC/RFID communications with #RaspberryPi and Adafruit
Adafruit has just published a guide to doing NFC/RFID communications with their breakout board. Read the guide
LED matrix with a #RaspberryPi
Frank, at Raspberry Alpha Omega, has worked out how to use WiringPi to drive a 7219 LED matrix. Read how he did it here
Learn and play piano in Minecraft with the #RaspberryPi
Martin O’Hanlon has written a tutorial and Python script to generate a piano and the notes to go along with it! Read more here
Fast I/O output to a TFT screen on a #RaspberryPi
Jean-Claude Wippler has developed a way to generate images on an LCD TFT touch screen breakout. Part of this has been to use Gordon Henderson’s WiringPi library. He has looked to see how quickly the GPIO pins can be switched…
A talking robotic bartender with the #RaspberryPi
Lots of projects news this morning! Steven Hickson has been working with a Raspberry Pi and an Arduino to create a voice-controlled talking robot bartender. He himself admits that it’s a bit slow, but it is very polite! The voice command…
Echo’s Room with Murmur and the #RaspberryPi – visualising sound waves / @Raspberry_Pi
This is an awesome project. “Murmur” is a device which takes spoken sounds and converts them into waves which it then uses as the source for a visual projection that is just stunning. More information can be found on their Project…
