rtlsdr-based spectrum analyzer on a Beaglebone

Greetings, It is my pleasure to share with you a small, fun project I made few weeks ago: an rtlsdr-based spectrum analyzer running on a Beaglebone with an LCD3 touch screen. Video demo: http://www.youtube.com/watch?v=jzmFXreuFR4 Howto guide: http://www.oz9aec.net/index.php/beaglebone/480-rtlizer I also took the opportunity to start collecting bitbake recipes to create sdr oriented linux images for embedded devices. It is available here: https://github.com/csete/nanosdr I don't intend to create full blown PC-like desktops, instead I want to have fast, minimalistic linux images that can run a single GUI app without any display or window management. Think of it as a radio or an instrument that happens to run linux :) Alex
