Why would an antigravity device need an infrared photo detector ?
I'd like to know what someone comes up with or I could take it to some engineers at Raytheon and have them tell me what such a combination of resistors, capacitors, etc would do...
The general principle is straight forward: An electromagnet pulls a ball upward until it interrupts a light beam that falls on a photodetector. As less light is detected, the circuit reduces the electromagnet's current. With less current, the coil effect is weaker and the ball falls until the light beam is less blocked. Voila! The ball stays balanced between these spots!
