Jeremy Blythe has done a comprehensive tutorial over on tuts+ in which he controls an Adafruit RGB LCD screen from the Pi and displays different tweets in different colours depending on content. Read it here
Plenty of #RaspberryPi articles in this month’s Linux Voice
New Linux magazine Linux Voice has published it’s next issue. This month there is the following for Raspberry Pi owners:
- A (well-balanced) 4-page review of Kano
- 4-page feature on Code Club (which isn’t strictly Raspberry Pi, but I thought I’d mention it)
- A great interview with the guys at Pimoroni
- A review of the book Raspberry Pi Assembly Language – Raspbian Beginners
- How to build a ‘mars rover’ using the PiBorg PicoBorg reverse
- How to build a wildlife camera box using the Pi
- A feature on ffmpeg and mencoder (which are common tools on the Pi)
Loads of #RaspberryPi stuff in this month’s Linux User & Developer magazine @LinuxUserMag
Linux User and Developer has fast become the best mainstream magazine for the Raspberry Pi. They regularly print multiple Pi features every month and this month’s is no exception. Here’s a list of the articles you can expect to find when it comes out in shops this coming week:
- A guide to ‘essential’ add-ons for the Pi including:
- USB cable with switch
- Adafruit 16-channel PWM/servo driver board
- PiBorg PicoBorg Reverse
- MCP3008 analog-to-digital converter chip
- Pi Camera
- The PiTFT screen
- Sharp IR range finder
- Adafruit Barometric, temp and altitude sensor
- Adafruit Electret microphone amplifier
- Adafruit stereo audio amplifier
- An entire mini-mag devoted to the Pi including:
- Dexter Industries’ BrickPi Bookreader project
- A guide to getting started with Minecraft Pi Edition (including a plug for Kano’s visual Minecraft programming environment)
- How to mine Bitcoins with the Pi
- How to use your Pi with BOINC and contribute to international scientific projects
- A feature on the Compute Module
- A guide to parallel processing on the Pi with the aim of building a ‘supercomputer’
- An review of the Wolfson Audio Card (which a higher-than-expected and deserved (IMHO) 4/5 rating)
Beautiful #RaspberryPi cluster
Continuing the recent spate of artistic projects using the Pi, David Guill has created a “supercomputer” using 40 Raspberry Pis. His project called for the following:
- Build a model supercomputer, which structurally mimics a modern supercomputer.
- All hardware required for the cluster to operate is housed in a case no larger than a full tower.
- Parts that are likely to fail should be easy to replace.
- It should be space-efficient, energy-efficient, economically-efficient, and well-constructed.
- Ideally, it should be visually pleasing.
You can read more about his project here, including complete build instructions or you can view a video of it below:
Use a Nokia 5110/3310 display with the #RaspberryPi
Adafruit has published a tutorial on using their library for this small Nokia screen with the Pi. Read it here
How to use #RaspberryPi in the classroom
Raspberry Pi Certified Educator Sway Grantham has written another blog post in her excellent series on using the Pi in the classroom. This time she explores the way in which the Pi can be used, including her ideas on what to do next in classes at different key stages. Read it here
