Build The Spirit Radio That Creeped Out Tesla Himself

“My first observations positively terrified me as there was present in them something mysterious, not to say supernatural, and I was alone in my laboratory at night.”
— Nikola Tesla, 1901

“The sounds I am listening to every night at first appear to be human voices conversing back and forth in a language I cannot understand. I find it difficult to imagine that I am actually hearing real voices from people not of this planet. There must be a more simple explanation that has so far eluded me.”
— Nikola Tesla, 1918

Instructables has the Tesla Spirit Radio building instructions:

The Spooky Tesla Spirit Radio is more than just a crystal radio circuit in a jam-jar. It’s a sound maker that plugs in to a computer, and makes awesome spooky sounds by responding to electromagnetic fields or light sources in real time.

Athough Tesla used different parts, this radio’s basic L-C (Inductor-Capacitor) circuit uses a similar schematic to what Tesla experimented with in his early days. The versatile 1N34A crystal germanium diode used here, substitutes for the tricky rotating nickel detectors and sensitive relays, used by Tesla in the late 1800’s.

You can listen to AM broadcasts with this radio, but it was made to have fun with in other ways. (Besides, AM radio wasn’t exactly what Nikola Tesla was interested in… in fact, he believed it was a waste of energy to transmit and receive Hertzian waves!)

Build a Tesla Spirit Radio for yourself and tell us how it works out!
