Raspberry Pi motion sensor with realtime alerts
Eric Grossman over at PubNub has written an interesting tutorial which uses an ultrasonic distance sensor. The sensor detects motion by taking constant readings and then uses the PubNub service to ‘subscribe’ to any alerts generated. Read more here.
Read temperature, pressure and altitude with the BMP180 sensor on the Raspberry Pi
Malcolm Maclean is developing an eBook for the Raspberry Pi and it’s available for you to read online. One of the sections of the book is all about the brilliant little BMP180 sensor (pictured above). This sensor, which replaces the larger…
Flappy Bird game controlled by brainwave activity via a Raspberry Pi
On 6th June, we held a Cambridge Raspberry Jam at the Institute of Astronomy in Cambridge. One of our Show and Tell tables was manned by Carl Monk and Albert Hickey. Albert has created a game called ‘Flappy Bird’ using Python…
Monitor your beer fridge with a Raspberry Pi
The guys over at Initial State have written a comprehensive tutorial to create an Internet of Things Beer Fridge! By using a Raspberry Pi, some sensors and a Wii balance board (!), the software is able to determine how many…
Measuring humidity with the AstroPi and the Raspberry Pi
Richard Hayler has also been working with the AstroPi. His school’s project is to detect the presence of an astronaut by measuring the amount of sweat in the air using the AstroPi’s onboard humidity sensor. He is documenting his work…
DiddyBorg with joystick control on the Raspberry Pi
The Diddyborg from PiBorg is a lovely, hard-wearing, speed robot. Richard Hayler has taken an old digital joystick he had lying around and hooked it up to a Slice of Pi prototyping board on the Pi so that the Diddyborg’s…
Eye-controlled wheelchair uses Raspberry Pi 2
Myrijam Stoetzer (14) and Paul Foltin (15) from Duisburg, Germany wanted to create a system whereby a wheelchair could be controlled by tracking eye movements. The eye tracker is made from a webcam mounted in the frames of some safety glasses. They use…
Raspberry Pi security camera using a RasPiO Duino
Alex Eames has been busy experimenting with a way to replace an old low-res security camera at his house in Poland. He’s come up with a Pi-controlled, servo-positioned camera that will accept commands over Twitter. The core of the project is…
Motion detection with a web interface on the Raspberry Pi
Karl Herrick has taken a PIR sensor and hooked it up to his Pi. He’s then used a variety of different software including the Cylon.js framework and Node.js to do the detection and provide a web interface for the sensor. It’s an interesting…
