Version 6

     

    Matthew relives some of his youthful hacking by dabbling in a little "pirate radio" broadcasting. In this video, he builds a handheld FM transmitter from some salvaged parts and a Raspberry Pi. The Pi uses a piece of software to convert wav files to frequency-modulated signals emitted from GPIO pin 7. To improve transmission quality and prevent undesired signals, Matthew also designs and builds a band pass filter and seals everything in a shielded case.
