Gadget Freak Case #149: Spirit Radio Receives Transmissions from the Beyond

As homage to Nikola Tesla and things that go bump in the night, Rick Crammond created this spooky sound generator that uses a simple crystal radio circuit connected to a PC's sound-in jack, Tesla-inspired plug-in antenna, and DSP software to control the gain and pitch of the circuit to create some great, real-time sound effects! The same radio circuit is a great RF field detector, makes cool sounds from all forms of light, listens to audio ranges, and even receives AM broadcasts. Because what could be spookier, really, than listening to a late-night, syndicated radio show host!
