This was the result of testing a scanner attached to a Raspberry Pi using SANE to scan to a remote file server. Something was(n't) working well.
Tonight I got as far as getting the RaspberryPi to detect when I'd hung up the phone and stop playing the radio.

How to install a USB webcam in Raspberry Pi

The quality of this video is crap, but I wanted to show off that I finally managed to get Qt5 running on the Raspberry Pi, even with Qt3D (which is not included in the easy to use qtonpi prepackaged image, which incidentally is armel and not armhf so it has worse floating-point performance).
Qt5 is an absolutely awesome platform for the Raspberry Pi.
The secret is all here (warning: both BuildRoot and Qt5 will take hours to cross-compile on your x86 PC)
github.com/nezticle/RaspberryPi-BuildRoot/wiki/Walkthrough
(Note: The ./configure command in the instructions for building qtbase is missing the option "-opengl es2". After hours compiling, when it finally came time to link it complained about not being able to link libGL and I had to start all over again. The Raspbery Pi doesn't have libGL, only libGLES)
To configure QtCreator 2.5 to use the BuildRoot qmake you can follow the instructions here (these are for qtonpi. Replace /opt/qt5/bin with your BuildRoot output host/bin path):
To get QtCreator 2.5 running on your PC (I'm using 64-bit Ubuntu 12.04) with the BuildRoot version of qmake and not complain about a bad “default mkspec” you have to copy host/usr/mkspecs as staging/usr/mkspecs in your BuildRoot output directory.
QtCreator 2.5 doesn't seem to be able to create new BuildRoot/Qt5 projects properly, so you have to:
* copy the hello-qtonpi project from qtonpi
* replace all instances of hello-qtonpi with your project name
* add the BuildRoot output host/usr/bin directory to PATH (check that “which qmake” leads to the BuildRoot qmake)
* run qmake once
* load the project into QtCreator 2.5 and continue normally from there
Using an ATtiny85 to control power the Raspberry Pi. Momentary switch is used to turn everything on and then to turn it off again later.

Now that you've finally got your hands on a Raspberry Pi, you're probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Plate from Adafruit, which can snap onto the Pi PCB (and is removable later if you wish) and gives you all sorts of prototyping goodness to make building on top of the Pi super easy.
We added lots of basic but essential goodies. First up, there's a big prototyping area, half of which is 'breadboard' style and half of which is 'perfboard' style so you can wire up DIP chips, sensors, and the like. Along the edges of the proto area, all the GPIO/I2C/SPI and power pins are broken out to 0.1" stips so you can easily connect to them. On the edges of the prototyping area, all of the pins are also connected to 3.5mm screw-terminal blocks. This makes it easy to semi-permanently wire in sensors, LEDs, etc. Finally, we had a little space remaining over the metal connectors so we put in an SOIC surface mount chip breakout area, for those chips that dont come in DIP format.
The nice thing about this plate is we're getting custom header breakouts that are taller than usual, so that the proto plate sits above the metal connectors, out of the way and allows for plenty of workspace. We'll have stackable header kits as well for those who want to put multiple plates on top.
What is the Raspberry Pi? A low-cost ARM GNU/Linux box.
The Raspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. The Foundation plans to support Fedora Linux as the initial system software package/distribution, with support for Debian and Arch Linux as well - Wikipedia.
*Please note, we are currently testing this product with the shipping Raspberry Pi and will release it once it's ready! We have not set the pricing or ETA yet.
*If Raspberry allows us, we'd love to become a distributor. We've asked, don't worry :)
