Ghostbuster fans are some serious-minded people. Mere toys aren't good enough for Halloween costumes. They demand attention to detail. Working lights. Moaning sound-effects. And so, I uncovered this: actual blueprints to make a real-as-it's-gonna-get proton pack. 

I'm not going to say it's an easy task. And time is indeed running out. So if these instructions seem too tough, you can always take the easy way out at 80stees.com.

But if you're really serious about the real thing, better open an account at Radio Shack and break out the soldering gun. Click here to get complete instructions from moresay.com.
