This year's focus for Bay-Net at Maker Faire was Software-Defined Radio and our projects are loosely grouped into three subtopics:
- Show use of low-cost SDR hardware with microcontroller platforms, primarily Raspberry Pi. These projects are primarily focused on doing basic tasks like filter analysis, receiving FM radio, etc. We're also showing use of low-cost SDR hardware running with inexpensive Android tablets such as Amazon's 7" Fire which often sells for only $39.99 and can be used to build a basic spectrum analyzer.
- Show applications of SDR hardware running on microcontrollers to do things like build APRS trackers, run azimuth/elevation rotors for tracking satellites, receive ADS-B info from commercial aircraft, and more.
- Show higher-end commercial SDRs for performance applications such as monitoring LTE.
