Ghostbusters Proton Pack for Halloween!

***UPDATE 5/3/10:  If you make a proton pack based on this slideshow, post a picture down in the comments, and I'll send you a patch!***

Update 10/31 - Just got back from the Halloween party, and added 4 pictures of me in full costume. Pretend the coveralls are tan. Warning: these pictures contain chest hair!

Well, I didn't think this would warrant a full instructable, as Honus created this instructable that I used to make my own Proton Pack. So, here is a slideshow of the the awesome costume prop I built. Sadly, I couldn't find a flight suit or even a coverall that was the right color, so I'm not sure what I'm going to do about that, but at least I have the proton pack!

Since Honus already did the the full instructable on this, I didn't document the construction process. Here is an (incomplete) list of the parts I used to build this:

1/4" plywood
an old backpack frame
LOTS of black spraypaint
duct tape
masking tape
electrical tape
packaging tape
foam weatherstripping tape
random wires
an old garden light
empty bottle of ibuprofen
PVC pipe
an old plastic dish
a spraypaint can
an IDE cable
toilet paper tubes
and many more things

I worked on this starting last sunday night. I worked on it every night that week, until at least midnight, and literally all day long both saturday and sunday. I put the finishing touches on it monday night. Let me know what you think, I'm very proud of it!

Nothing that can't be found in my three different instructables on the subject. Just go for it and don't worry too much about making it movie perfect. Post some pictures when you're done!

It used to be that you could order them cheap off of, but the FDA got involved and now you have to be licensed to buy anything higher than 5mw.  

You can harvest a 200mw red out of a DVD burner, but they're very easy to break.  Also, and this is VERY IMPORTANT, you can seriously screw up your eyes, PERMANENTLY, if you don't have a pair of laser protective goggles, or I'm guessing you'd need several pairs if you're going to put this in the science fair.  Really man, go to and read some of the things people have written about the importance of getting good safety goggles.  You can go blind for the rest of your life, or make someone else blind if you catch the beam directly or even from a reflection off of glass, plastic, metal, water, etc.

If all you need is a visible beam laser, get a 5mw green from dealextreme.  Our eyes are well adapted to green light so it's quite easy to fire it through smoke or steam or fog or dust or something and have the beam be seen.


idk if this is true or not but a 52mw laser you can see the beam right?? if it is true you should make on and put it on the proton wand ????idk byezzzzz

Depending on the color of the laser and the ambient lighting conditions, yes you can see the beam.  However, anything over 5mw is dangerous so shouldn't be flashed around in a public place. 

Speaking of lasers, I've added two to my proton pack for halloween this year, so you should stay tuned for that!
