Andy Fundinger from Plivo was spurred on by his experiences at PyCon 2013 and has experimented with his Pi by creating a rather neat 4-button arrangement that can be used by a child to contact their parents. It’s quite a cool little project for beginners. Read more here
One of the worst-kept secrets ever has finally been revealed by the Foundation. The new camera module without the IR filter, known as the Pi NoIR. DesignSpark recently released some time lapse videos of it literally ‘in the wild’.
No word yet on when it will be available for purchase, though the Foundation does have working prototypes so it can only be a matter of weeks.
Over on Slice of Raspberry Pi, they’ve been developing a sweep generator, also known as a wobbulator. Here’s what they say about it (it’s a bit beyond me!)
A wobbulator (or sweep generator) is a piece of test equipment which is used in conjunction with an Oscilloscope to measure the frequency response characteristics of a circuit. It uses a “ramp” or “sawtooth” function generator connected to a Voltage Controlled Oscillator (VCO) to produce an output sweep over a defined range of frequencies. The response characteristics of the circuit under test can then be displayed on an Oscilloscope. A wobbulator is a useful tool for aligning the intermediate frequency (IF) stages of superhet receivers, but can also be used to measure the frequency response characteristics of RF filters and other circuits.

David Whale (@whaleygeek) was asked to help Greenpower display race timings for their event. I’ll let him tell you all about the project on his blog. It’s BIG Read here
David Briddock has blogged about using the BlueJ graphical programming environment for Java. It’s similar in concept to Greenfoot but is targeted at students of the language.
