Raspberry Pi E-mail Notifier Using LEDs Prepare Python: Raspberry Pi’s popularity make things so easy that it is almost scary. I set forth on a simple starter project of having the raspberry pi show me when new gmail messages arrive. After some searching it seems that lots of people are already talking about how to do this and there are some great examples. Michael over at MitchTech had the most ready to go code which I pilfered from. Adafruits Cobbler Breakout Kit makes the bread board experience even easier with the clearly labeled pins for each of raspi’s GPIOs. (read more)
Adafruit 16×2 Character LCD + Keypad for Raspberry Pi: This new Adafruit Pi Plate makes it easy to use an RGB 16×2 Character LCD. We really like the RGB Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins. With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi!

Ben gets to work on a Raspberry Pi gaming device you can take anywhere. In part one Ben gets the electronics working and installs MAME on the Raspberry Pi.
Doug Jackson makes word clocks, and he must be doing quite a bit of business. We say that because he put together a programming and test bed for the clock circuit boards.
This is a great example to follow if you’re doing any kind of volume assembly. The jig lets the populated PCB snap into place, making all the necessary electrical connections. This was made possible by a package of goods he picked up on eBay which included rubber spacers to separate the board from the acrylic mounting plate, pogo pins to make the electrical connections, and a spring-loaded board clamp seen to the left in this image.
The switch in the lower right connects power to the board and pulls a Raspberry Pi GPIO pin high. The Python script running on the RPi polls that pin, executing a bash script which programs the ATmega169 microcontroller using the GPIO version of AVRdude. We looked through his Python script and didn’t see code for testing the boards. But the image above shows a “Passed” message on the screen that isn’t in his script. We would wager he has another version that takes the hardware through a self test routine….
Linking 56 Raspberry Pi computers together in LEGO racks, The University of Glasgow’s Raspberry Pi Cloud project creates offers student researchers a chance to work hands-on with a platform designed to mimic a multi-million dollar commercial cloud. Via The University of Glasgow:
In recent years cloud computing has become increasingly popular, with major corporations such as Google, Amazon and Microsoft making huge investments to provide software and hardware resources to business and home computer users over the internet.
However, cloud computing service providers maintain a great deal of secrecy over how their systems work beyond the software available to end-users, making it difficult for computer science researchers and students to develop practical understanding of cloud infrastructure.
Dr Dimitrios Pezaros, Dr Jeremy Singer, Dr Posco Tso and Dr David White of the University’s School of Computing Science developed the Raspberry Pi Cloud project to broaden access to cloud computing research and education.
…Dr White added: “Before we built the Raspberry Pi Cloud, we relied on software models of how cloud data centres worked for our research and teaching. Software simulations can be valuable but they are not wholly successful at replicating the practical difficulties of running a data centre.
“What our Raspberry Pi system gives us now is a very clear correspondence between the hardware and the software, and a physical setup which is very similar to how racks of servers work in real data centres. We’ve been really inspired by having a practical model to experiment with.
“The ARM processors which are used in the Raspberry Pi are also becoming more common in cloud data centres because they require less energy to run than more traditional PC hardware, which gives our students another advantage for their future careers.
“At the moment, the Raspberry Pi Cloud is available for students to work on, but we’re keen to integrate the project more fully into our courses and make cloud computing a key part of our teaching programme.”
Here’s an update for BrickPi, the Raspberry Pi LEGO robotics shield created by Dexter Industries, now in the last stretch of a successful crowdfunding campaign that will help bring the price of the final units down to match the RasPi as well as upgrading the hardware and software libraries to make the shield more useful. Via Techcrunch:
As its name suggests, BrickPi is a mash-up of the Raspberry Pi microcomputer, co-opted to act as the brains of the robot, plus LEGO Mindstorms sensors, bricks and motors for crafting its working parts. Firmware is written in Arduino, making it open and hackable. Indeed, the BrickPi makers have put their hardware designs and software source code online for download on Github.
The BrickPi extends the Raspberry Pi with a board that snaps in place over the Pi to connect it to the various LEGO sensors (such as touch sensors, colour sensors and gyroscope). This is then contained within a plastic case that is compatible with LEGO bricks so it can act as the base for building out the robot. An on board battery connector allows the robot to be untethered from a power socket so it can go roving.
The BrickPi is the brainchild of educational robotics company Dexter Industries which also sells sensors for LEGO Mindstorms…. Going the crowdfunding route sounds like it was primarily about building a community and getting the word out for Brick Pi’s makers but they have added a series of stretch funding goals to explain what they plan to do with the extra money raised. These include adding more sensors and ports to the device and creating additional libraries (in C/C++, as well as the original Python libraries) to expand programming options.
“We have a lot of plans for the extra funds raised and they all include improving the user experience and opening up the BrickPi to a wider audience,” says Dexter Industries’ John Cole. ” That mostly means putting together some sharp tutorials, and putting together more examples. In my humble experience, where a lot of technical projects like this go wrong is when they have only 2 or 3 example projects. Adults can think of a lot of projects and interesting ways to use the product, but kids have trouble with it, get bored, and move on.” …
If you’re anything like me, you’ve wondered what happens in your garden while you’re not watching. I wanted to know when birds are most active – are they busier in the evening or early morning? Thanks to the latest technology, now with a couple of taps of my smartphone I can monitor the bird activity in my garden from anywhere in the world.
Traditionally, recording bird activity was a manual process and required many hours of constant nest watching. Springwatch has an army of story developers watching cameras and noting activity round the clock. I didn’t fancy hours watching a bird box so wondered if I could get a computer to do it for me.
Last February, a new tiny computer, the size of a credit card sized went on sale for £30. The quirkily named ‘Raspberry Pi’ computer was created to get more people interested in computers and I’d become aware of it through my work with the School of Computer Science at The University of Manchester. The Raspberry Pi computer’s diminutive dimensions and low cost meant it could be placed where computers had never been placed before – for me, that mean in a nest box.
The tiny Raspberry Pi computer records when birds enter and leave the nest box, together with information on the weather. This information is sent over the Internet so activity can be monitored from anywhere.
We’ve been monitoring a blue tit nest here at Ynys-Hir with the computer. The latest data is shown below. The orange bars show the number of visits per 1.3 hours, the red line shows temperature and the green line shows wind speed. I’m hoping to post more graphs later….
Ground control pushes various health information to the cloud. Make dashboards, set alerts, notice problems, and see how your Pi is doing from anywhere.
Ground control supports Librato and TempoDB out of the box.
Make your own app
Add any command you want to Ground Control’s configuration file, and it will be picked up automatically.
Your commands and controls are laid out in a responsive Web UI, accessible with any device with a browser.
Built with Go
Ground Control was built with Go and strikes a very small resource profile (just a few megabytes of RAM).
With Go, there’s no friction either – just download and run a binary prepackaged with everything you need.

Thanks to Maximilian Batz from http://www.pi3g.com/, who sponsored two Raspberry Pi B models for the cause of Apollo-NG, it was time to see what more could be done with them. This essentially forked two subprojects:
Raspberry Pi based autonomous Antenna Tracker (following a MAVLink enabled UAV/Drone)
Raspberry Pi based geiger-counter
The Tracker is working but still in alpha state (built as a mockup) and not released yet but after a combined amount of 10 days the PiGI – Raspberry Pi Geiger-Müller Interface was finished, including the prototype boards. Some basic documentation is done, the github repo is online and basic prove-of-concept code is finished. It goes to show how amazingly fast we can dive into new technologies today and come up with a new thing without having any prior knowledge how to build a geiger counter. Sharing knowledge via Internet simply rules
The fun thing about this project was that it also served as a test to determine if the lab, tools and equipment carried by Apollo-NG would be sufficient to build it. During the development and building, no technologies could be used to make it. Only tools/resources that are available and run on a 12V power rail (including soldering)….
