I happen to stumble upon this website while looking for tutorials/plans to build a full proton pack,
ghost trap and PKE meter for a local anime and movie cosplay gathering next year.I do happen to
use to watch both movies and the cartoon back in the 1990’s.
Ghostbusters related items I have is:
Ghostbusters the video game for PS2
And hopefully 1/6 scale of Peter Venkman, Egon Spengler, Ray Stantz and Winston Zeddemore
later in the next year.
