Hi my name is and I live in . Protects I want to do are 1. A P.K.E Meter that actually Detects Ions and free electrons in the air
Paragoggles that see into the Infrared spectrum
A sniffer that looks for natural gas and signs of ionization
Giga meter with a PIN photodiode array to detect ionization energies
Other than that maybe that machine that they use to detect Vigo’s Spirit in the painting
Hello there and welcome!
Some of those ideas are actually what I also had in mind. If you’re really serious about making actual functioning equipment then I would suggest checking out YouTube tutorials or the Ghostbusters Discord.
I have actually posted the links to those videos that may help implement functionality to those Ghostbusters props in the Ghostbusters Discord.
My thought was to handcraft an emf detector with a PKE meter aesthetic. The Paragoggles utilize a nightvision by using inferred leds which can be found in tv remotes. I wish you the best of luck and I hope to see more of your work.
