At Picademy , our awesome free training course for teachers, I run a workshop to introduce teachers to using the camera module with Python, and show them how to wire up a GPIO button they can use to trigger the camera. I always make a point of saying “now you know this, what can you make it do?” and suggest some uses for the setup – stop-motion animation, motion sensing or sending pictures to Twitter

Teenage electronics enthusiast Lewis Callaway thought that an ad in which actors launch rockets from their iPhones was really cool, but he couldn’t find out how it was done, so he decided to start from scratch himself, using (of course) a Raspberry Pi. Model rockets are launched by passing an electric current through an igniter, a device that includes a thin piece of wire in contact with the rocket’s propellant; the current causes the wire to heat up, igniting the propellant. Lewis used a relay board and jumper leads to complete the circuit between a 9V battery and the model rocket’s igniter, and connected power and signal wires between the relay board and his Raspberry Pi’s GPIO pins so he could flip the switch on the 9V circuit with a signal from the GPIO

PiPhone – home-made Raspberry Pi smartphone
At the end of February, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack for the BCM21553 cellphone chip. To celebrate, we offered a $10k prize to the first person to port this codebase to the BCM2835 application processor that sits at the heart of the Raspberry Pi, and to get Quake 3 (which already runs on the Pi) running on the newly open ARM driver, rather on the closed-source VPU driver. Our hope was that the ported driver would be a helpful reference for anyone working on a Mesa / Gallium3D driver for VideoCore IV

Dave Conroy has done something pretty exceptional with his Raspberry Pi: he’s turned it into a speech-recognising translator that recognises 60 different languages, and plays its native-speaker version of your phrase back for you. It can cross-translate between thousands of language pairs

Integrating NetBeans for Raspberry Pi Java Development Automated Trader (blog) The Raspberry Pi is an incredible device for building embedded Java applications but, despite being able to run an IDE on the Pi it really pushes things to the limit. It's much better to use a PC or laptop to develop the code and then deploy and test …
