This year has flown by and we are back with our Christmas issue once again! Is Santa bringing you any Raspberry Pi goodies this Christmas? If so we have plenty of great articles to help you put this clever computer straight to good use.
Are you bored of having your presents delivered by reindeer? If you fancy a change, why not have your own Pi-powered quadcopter air drop them in? Andy Baker begins his series on building this flying machine covering in this issue the parts required, their function and discusses some of the coding used for lift off…. no, it’s not powered by Christmas spirit!
If you are too busy attending Christmas parties and are missing your favourite soaps, never fear, we have you covered. Geoff has produced a great article on OpenELEC, bringing you catch up TV on your Raspberry Pi so you never have to miss an episode again! Claire Price continues the festive spirit with a fantastic article on Sonic Pi which will have your Raspberry Pi singing along with a rendition of Good King Wenceslas.
We saw the PiMSO, a RPi powered 200 Msa/S oscilloscope, at OHS 2013 and wanted to share this great project:
PiMSO, is a Raspberry Pi controlled 200Msa/s mixed signal oscilloscope. PiMSO, a spinoff of WebMSO, is an experimental project to understand the necessary components required to deploy the MSO-28 mixed signal oscilloscope on mobile devices. With the ever growing list of mobile platforms, it became very difficult for PC based instruments developer such as Link to keep up with the demands to supply driver applications for various platforms. Upon examining the complexities required with different solutions, we arrived on a client/server solution. The client part would be web browser based, because of the near universal availability on most devices. Browser based also meant driver free deployment on the mobile devices. The challenge would be to create an affordable gateway server to the MSO-28. After experimenting with various embedded solutions, we realized that we cannot manufacture an affordable solution at our sales volume. With the availability of existing low cost ARM based devices on the market, it would be more economical for our MSO users to leverage these and roll their own solution while we provide server side hardware driver support.
Thanks to @adafruit, the new PiTFT, it works great and your instructions made it simple as Pi to use! #RaspberryPi pic.twitter.com/5Y5HGOCT5G

PiTFT Mini Kit – 320×240 2.8″ TFT+Touchscreen for Raspberry Pi – Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! (read more)
Samy Kamkar’s SkyJack is a “drone engineered to autonomously seek out, hack, and wirelessly take over other drones within wifi distance, creating an army of zombie drones under your control.” –
Today Amazon announced they’re planning to use unmanned drones to deliver some packages to customers within five years. Cool! How fun would it be to take over drones, carrying Amazon packages…or take over any other drones, and make them my little zombie drones. Awesome.
Using a Parrot AR.Drone 2, a Raspberry Pi, a USB battery, an Alfa AWUS036H wireless transmitter, aircrack-ng, node-ar-drone, node.js, and my SkyJack software, I developed a drone that flies around, seeks the wireless signal of any other drone in the area, forcefully disconnects the wireless connection of the true owner of the target drone, then authenticates with the target drone pretending to be its owner, then feeds commands to it and all other possessed zombie drones at my will.
SkyJack also works when grounded as well, no drone is necessary on your end for it to work. You can simply run it from your own Linux machine/Raspberry Pi/laptop/etc and jack drones straight out of the sky.
Sam writes: “I had a crack at another Christmas project this year connecting a RasPi, Arduino, webcam and some WS2801 pixels to make a set of lights your can control and view over the internet. I also hacked my toy train so you can control it to. I have a bit of an explanation on the site and I still have to write a little more code and solder a few more wires but it’s up and running! ”
What do you get if mix a Rasberry Pi, Arduino, some RGB Pixels and a Christmas Tree??? The xMasPi of course! I have the tree on most nights, so if it’s off come back later
Use the controls below to control the lights and train. Once you take control you only get 1 min before your logged out. Feedback is appreciated and please be patient, the camera feed is pretty slow and the site wont work with Internet Explorer (use Chrome!).
Today my idea was to build an Arcade Stick that can be directly plugged to TV like the old good C64 DTV, but now with “everything”.
- Acryl Arcade Stick: all the nice tech stuff can be shown.
- Raspberry PI with 32Gb SD, packed with emu stuff plus WLAN Adapter
- PiJamma PCB for connecting Arcade Controls
- HDM plug
- USB plug
- PSU connector
- LED Modded buttons with new Acryl holder
- Buttons with inlay artwork
- Aluminium Panel
- NeoGeo 4 Button Layout
- Sanwa JLF Stick unit with Link. Stick can be pulled off.
Looking good! See here for lots more build documentation!
Andrew Back‘s used a Raspberry Pi to build an internet radio that only receives BBC Radio 4:
Tuning controls and station presets? Why on earth would anyone want such things! As far as I’m concerned the only thing worth listening to on the wireless is Radio 4.
With the above in mind, I decided to build myself an Internet radio that is fixed on Radio 4 and which dispenses with unnecessary clutter, with the only control being for power and volume.
At a flea market earlier this year I picked up a 1950s extension speaker made by Richard Allan. Comprising of simply a cabinet, loudspeaker, step attenuator and input socket, and with plenty of spare room inside, this was ideal for converting into a Raspberry Pi-powered Internet radio.
OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). It is based on the design of OpenSprinkler, but its ‘brain’ is an RPi instead of an AVR microcontroller.
Ray has published everything you need to create your own OpenSprinkler Pi. Check it out here!
The above image was taken on Thursday 21st November during a Welshot Chester Academy Evening. The theme this month was “light painting”.
The Welshot logo was actually “painted” with a LED / Raspberry PI open source system that I made using instructions from Adafruits site below: learn.adafruit.com/light-painting-with-raspberry-pi/
For more information about Welshot see their site: www.welshotimaging.co.uk
Thanks for the heads up, Mark! If you’re interested in trying this out for yourself, check out the tutorial below from the Adafruit Learning System.

Light Painting with Raspberry Pi – Light painting is an artistic photographic technique combining long exposure times with lights in motion. Traditionally these images have been hand-painted with a penlight…but more recently, affordable microcontrollers and addressable RGB LEDs have brought a new high-tech twist to the idea. (read more)

Carrie Anne says that this book is for any young person who’s interested in making things happen using computing. Inside, you’ll find nine projects (alongside stickers, achievements and more), which will take you from a standing start to a point where you’ll be breezing through projects like writing your first programs, shaping the Minecraft universe using Minecraft Pi, designing and building your own role-playing game, writing and playing your own music…and making electronic switches out of marshmallows.
It’s a beautifully produced book, full of ideas and clear direction, with a real sense of Carrie Anne’s personality jumping off every page. These projects come out of real activities Carrie Anne has worked through with real kids; they’re tried and tested – and they’re fun, too. You’ll find hints and tips to help you along the way. There’s plenty of extra material online to supplement the book, along with lots of recommendations for further reading.
