Spectrum Analyzer using Beaglebone Black and RTL-SDR

Over on YouTube, Stephen Ong has posted a video of his standalone Terratec RTL-SDR and BeagleBone Black based spectrum analyzer. What makes this unique is the lack of computer needed and dedicated 7 inch touch LCD screen (CircuitCo LCD7 cape). Powered by 6 AA batteries, the unit is nice and portable. BeagleBoards are low-cost, fan-less single-board computers based on low-power Texas Instruments processors featuring the ARM Cortex-A8 core. The BeagleBone Black DevKit used in the video costs around USD$50. He demonstrates the unit showing the RF spectrum of  commercial FM stations, car remote transmitters, analog TV (PAL B) broadcast, DVB-T broadcast, cellular GSM900 and a DECT cordless phone.
