How to disable the red LED on the Pi Camera Module. Mine hasn’t arrived yet but I’m definitely trying this really simple hack when it does.
No idea if this works in the UK but certainly worth a go. It combines a Raspberry Pi, a USB TV receiver and some software to track ADS-B signals from overhead aircraft!
Some great work from the team at IC Robotics has turned the Pi into an FM radio! Capable of playing back wav files via a Python application (backed with a custom C library).
At the moment it’s Mono only and there are some issues with CPU priority but it’s a great starting point.
And there’s more, Guido PE1NNZ has released code to enable the Raspberry Pi computer board to generate SSB on the 7 and 14 MHz bands. SSB is used in HAM radio around the world and Guido has managed to make contact with other users across Europe via his Pi.
