I can’t say whether or not this Proton Pack will actually trap ghosts, but from this brief glimpse, there is one thing I can say for certain: this badass project is sure to score the top prize at Halloween costume contests, and isn’t that worth more than a ghost in a box?

The entire costume–you didn’t think it was just the Proton Pack, did you?–took Instructables ghostbustin’ guru depotdevoid two years to perfect. Not two entire years, mind you, but two years of costume-compiling. I can’t say I blame him; if I made a costume this awesome, I’d wear it every year.

A khaki flight suit, lasers (!), props, and an Arduino are the key elements required to build your own Ghostbusters costume, though I also recommend such luxuries as time and enthusiasm. However, from the instructions, it seems like just about any big Ghostbusters fan could put this together, if they were dedicated enough… thanks to the handy guide, anyway.
