Portable Homemade Spectrum Analyzer using a Beaglebone Black and the RTL-SDR

On YouTube, Stephen Ong has posted a video (and written a short post on his blog) of a portable home made spectrum analyzer he made using the RTL-SDR, a Beaglebone Black and an LCD touchscreen. The Beaglebone Black is a small Linux capable PC that fits in a hand, similar to the Raspberry Pi but with slightly more processing power.

Earlier in the year we posted about another Beaglebone based spectrum analyzer, but this new one by Stephen seems to be much improved with touchscreen capabilities and an improved user interface.
