I posted about making a ghost trap prop and showing the electronics I was prototyping. I finished it a while back and am just now getting around to showing it. I used the countspatula files from Thingiverse: Ghostbusters Ghost Trap (1984) by countspatula - Thingiverse
I have a walkthrough and demo on youtube: https://www.youtube.com/watch?v=z6mbjhX0XbM
