I just wanted to start off by saying thanks to all of you who post here. I’ve been lurking for two months, gleaning information from you for my own build. It wouldn’t have been possible without that help!
That being said, there’s a few caveats on my build. It’s not screen accurate, and it’s made from dollar store pieces. This is for my wife’s costume (I’m making myself a Stay Puft costume). But even though it doesn’t compare to the works of art some of you build, I’m pretty happy with the results, and thought I’d share 
The pile of pieces procured from the dollar store:
The initial layout:
My sloppy internal wiring for the lights on the cyclotron:
Hand-cut logo for the jumpsuit:
The assembled, unpainted pack:
The finished product:
I did want to have a few more pieces on it, but I ran out of time. Again, thanks to the community for all of your ideas!
