"While I was studying for my Ph.D. at the University of Cambridge, I also worked for the university as the Director of Studies, organizing undergraduate studies. Every year we got fewer people applying to study computer science, and every year the sorts of things incoming students knew how to do got less impressive." That is how Eben Upton described his motivation to construct Raspberry Pi in a Wired interview.
In 2006 today’s Executive Director of the Raspberry Pi Foundation began to develop the single-board computer with his colleagues. Six years later they launched the first model on the market. More than five million have been sold so far. They can be connected in the normal way with a display and a keyboard and used as a computer, as a media center, or to realize ideas for the Internet of Things. All about M2M has taken a look around the scene and here presents several exciting projects:
The Smart Doorbell
Classic doorbells have a serious drawback. Residents must always be within hearing distance. If, say, they are in the garden or turn up the volume of their music, the visitor will have to wait. For people with impaired hearing or who are deaf the situation is even more difficult – and that is why Daniel Garden has connected his doorbell to his smartwatch. Here is how he outlines the project on Twitter:
If somebody rings the doorbell Raspberry Pi automatically sends a message to a terminal device. Garden used his Pebble smartwatch, which draws attention to itself by vibrating and emitting a message sound and indicates on the display that somebody has rung the doorbell. This is how it looks in practice.
If you now feel interested in connecting your doorbell by means of Raspberry Pi, take a look at the instructions on Garden’s blog.
The Magic Mirror
What most people see when they look in the mirror is their own mirror image, but the Dutch hobbyist Michael Teeuw sees more. His connected mirror shows the latest weather forecast, the day’s news headlines, and his upcoming dates.
