In the early 1900s, electrical pioneer Nikola Tesla supposedly created a “crystal radio” that could channel the spirit realm. He believed he was hearing aliens or intelligent voices. Other scientists caught on to this. Such as Marconi and Edison. Now, with the help of an engineer, we are able to offer this device to you, for use in experimental EVP work.
"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 article "Talking With The Planets"
Tesla Spirit Radio
The Tesla Spirit Radio is many things in one. As a crystal radio set, it is inherent that those frequencies associated with EVP have been captured. Much like the Raudive's Crystal Diode Receiver but with specialized Tesla coil antennas and a variable capacitor.
The Tesla Spirit Radio is more than just a crystal radio circuit in a jam-jar. It's a sound maker that plugs into a computer or a amplified speaker and makes awesome spooky sounds by responding to electromagnetic fields or light sources in real time.
Although 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 be used 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!)
By using a program like Audio Hyjack Pro (Mac) or Adobe Audition, the radio's output is tweaked at the computer to give some great real-time sound effects...and you can record them at the same time.
The below video shows the many uses of the Tesla Spirit Radio. For EVP use, you can connect the audio output cable to an amplifier, voice recorder or computer program like Audacity or Audio Hyjack (for MAC).
