As a subject which combines the inventions of Tesla and interesting research tool for paranormal research groups, we just had to share it. Tesla’s Spirit Radio uses a simple crystal radio circuit connected to a computer sound-in jack to generate spooky sounds from all kinds of electromagnetic sources.
As you can read from his quotes , it creeped the hell out of 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
Watch the video and see what the radio can do and, if your are so interested, build one and decide for yourself:
