In a Twitter video posted on Thursday 16th April 2020, popular astrophysicist, Neil deGrasse Tyson demonstrated how he used the power of his mind to turn on a lamp.
Tyson in his post explained that he had made use of his brain’s beta waves to accomplish the feat. In addition, he mentions that the other gadget that helped him do this was an electromagnetic BlueTooth Relay.

Mind over Matter
My brain’s Beta Waves turned on a lamp, via an electromagnetic Bluetooth relay, invented by Trent Johnson, an AV-tech I met in Asheville, North Carolina after a public talk I delivered there.

The relay was invented by Trent Johnson, who is an engineer. According to Neil deGrasse Tyson’s brief explanation, the gadget read his brain waves after he put on a cap containing some other electronics.
Beta waves are neural oscillations that occur in the brain. Usually, it has a frequency range of between 12.5 and 30 Hz (that is 12.5 to 30 cycles every second). They are electrical brain activities that happen when humans are conscious — as opposed to Alpha waves which happen when they are unconscious.
So, how did Neil deGrasse Tyson turn on the lamp with his mind?
We found a well-explained answer from another Twitter user. James Atts, PhD said:
“Sensors and actuators. A sensor on the cap detects the brain waves. A transmitter, attached, sends a radio signal to the receiver in front of him, which activates an on-off actuator that switches on the lamp.”
While the explanation is simplistic, it does not limit the tech to an ordinary “complicated remote control”. As another user pointed out a possible application: imagine a person immobilised by illness being able to turn on radios, TV and lamps by themselves.
