Please keep in mind, we are not full time linux distro maintainers – we will try to fix any bugs we find but this distro is not for beginners or people who are new to linux! NOTE: Be sure to check the MD5/SHA checksum before uncompressing/burning to your SD – it’s a big file and you can have Pi instability if a few bits are wrong!
How to Add Real Time Clock to Raspberry Pi. The Raspberry Pi is designed to be an ultra-low cost computer, so a lot of things we are used to on a computer have been left out. For example, your laptop and computer have a little coin-battery-powered ‘Real Time Clock’ (RTC) module, which keeps time even when the power is off, or the battery removed. To keep costs low and the size small, an RTC is not included with the Raspberry Pi. Instead, the Pi is intended to be connected to the Internet via Ethernet or WiFi, updating the time automatically from the global ntp (nework time protocol) servers
For stand-alone projects with no network connection, you will not be able to keep the time when the power goes out. So in this project we will show you how to add a low cost battery-backed RTC to your Pi to keep time!

It does not have any resistors or other connections inside for the data lines so this won’t work for charging an iPhone, iPod or iPad or other device which expects some sort of resistance on the D+ and D- connections. It does, however, work great for Arduinos, BeagleBones, Raspberry Pi’s and most other USB-powered gadgets.
Easily connect your Raspberry Pi to web services and social networks! This tutorial demonstrates how to painlessly send and receive Gmail on the Raspberry Pi from Python, which in turn, allows you to easily connect it to web services and social networks like Facebook, Twitter, and more! This would normally be well beyond the abilities of most users due to the inherent complexities of programming through social media APis, client/server authentication, etc. However, with the easy-to-use web service Swiss Army knife ifttt (if this then that) anyone with even the most basic programming skills can dramatically expand the capabilities of their Raspberry Pi.
The 2012 Paralympic Games kicked off with an awesome opening ceremony that celebrated the spirit of human accomplishment, with a strong focus on the sciences. The ceremony featured an opening monologue from Stephen Hawking, a musical piece inspired by Newton’s Principia Mathematica, and a theatrical simulation of CERN’s Large Hadron Collider. Wired’s Sophie Brown explains it best:
Whilst some may wonder what these things have to do with disability; they don’t. They have instead to do with ability, our ability to achieve greatness in many forms despite whatever setbacks we may face. This is the message the ceremony wanted to put across. The organisers have named the show “Enlightenment”.
There’s a wonderful allegorical quality to the whole thing, which distills to the message that human passion and determination can overcome the greatest of obstacles.
The remarkable drive of all the athletes at the 2012 Paralympics is inspiring to anybody who’s ever dared to do the difficult things — I wish them all the best of luck!
I have just reached 15 days continuous uptime on my raspi (running adafruit packaged raspbian).
This raspi is running a custom twisted server which is communicating with a locally connectedJeeNode V6… which controls a 3 phase bore, several DS18B20 temp sensor (one immersed in water) and a Milone liquid level sensor.) The remote node manages water level in a 20m x 5m plant filter for a 120,000 litre capacity collection of 80 ponds growing water lilies and Koi.. as well as monitoring environmentals. Details are continously posted to cosm. In addition I can monitor and control solar power LED flood lights with PIR sensors from the raspi remotely over the same wireless network. The JeeNode is connected to the raspi via serial GPIO pins and is drawing power from the +5 pin on the raspi.
I am very impressed with the reliability and how easy it was to get things going especially given how new the hardware and distro’s are.
For one of my Pi projects I wanted the ability to send SMS text messages from a Python script. These messages would be sent to my mobile phone and alert me about specific events recorded by my Pi. There was no possibility of connecting the Pi to a mobile phone so I decided to send the SMS via the internet.
In previous years there were services that allowed you to send free text messages via the Internet. In general these services were either illegal or relied on loopholes in mobile phone networks that have since been fixed.
So the only reliable solution is to use an SMS Gateway.
I saw a post from Adam Wolf on Google+ today about the UN opening up an icon collection, and it jumped out at me right away. I love icons. They’re hard to do well, and a great way to communicate basic information, whether on a sign or on your PCBs. It was a nice reminder to me as as well since I actually started my career at the UN — in OCHA even (Office for the Co-ordination of Humanitarian Affairs), the same branch behind these icons — and it was one of the more memorable moments in my life for the opportunities it offered me down the road, and the people I met (including my wife!). The UN icon collection is licensed under a creative commons license and they can be seen on thenounproject.com with a lot of other interesting icons if you’re interested.
