So last year, I was a Ghostbuster for Halloween, using the incredibly awesome proton pack I built.  There were a couple of problems with the costume, so I decided to fix them and upgrade the costume for this year's Halloween.

While I was sitting around rewiring, touching up, and adding arduino control to my pack, my daughter told me she wanted to be my "Ghostbuster Assistant."  I kind of hemmed and hawed and told her I didn't think I had the time or money to build one this year, but the idea simmered in the back of my brain for a while and later on that week I realized that not only did I have enough time to do it, but I had almost everything I needed already on hand! 

Total cost for this project: $15.88 (under $20!)

Most of the materials were scraps of cardboard and plywood, various doodads and gizmos I had in my shop, and lots of stuff rescued from the recycling bin.  The electronics, tape, and hot glue I already had.  All I had to buy was one tube of E-6000 epoxy (4.99) and three cans of super cheap flat black spray paint (.97/each).  Also, I had to pick up an old backpack from value village (2.99) for the the straps.  Oh, and a khaki jacket from goodwill (4.99).

Here's a brief description of the controls:

***UPDATE 5/4/10:  If you make your own ghostbusters costume, go ahead and post some pictures in the comments below.  I'll send you a patch!***

Step 1: Gather materials

Okay, as I've mentioned before, user Honus has made a very nice and much more professional 'ible on how to make a Ghostbusters Proton Pack.  I used his instructable for reference, but the main difference was in the materials.  Also, I didn't bother to stay exactly true to the movie props, which I'm sure for "serious" fans is a no-no.  I wanted the pack to LOOK like a Proton Pack, not actually BE a Proton Pack (or to have to run around finding all of the exact parts).  The dimensions I used were based off of several prints available at this website, and I stayed as true to the plans as I could, but I didn't limit myself to them.  I also made my rough measurements about 2/3 smaller, so it would be more kid sized.

I used mainly cardboard, tape, hot glue, and epoxy to make the packs.  Here is a (probably incomplete) list of the materials you should have lying around to make a kid sized (or a full sized) proton pack:

1/4" plywood
Lots of cardboard - big boxes and a variety of smaller boxes is helpful
Duct, masking, and electrical tape
2" thick styrofoam (I used this because I had it, but cardboard would work too)
Flat black spray paint (Home Depot sells cheap cans for .97/each)
Hot glue
Epoxy (I like E-6000)
Strong magnets
Split plastic conduit material
Probably about 10-15 feet of light gauge speaker wire
LED's, perfboard, a 555 timer, switches, buttons, capacitors, resistors, flashy kids toys from the dollar store
1/2" and 3/4" PVC (about 8 feet of each)
Eye screws
An IDE cable from an old computer
Some colored wire
Miscellaneous bottle caps, screws, bolts, zerks, tubes, pill bottles, and any other sorts of things that might look nice once they've been spray painted
<p>Hi was wondering what did you use for the transparent tip of the gun? thanks!</p>
<p>You should have had her tuck the jacket into the pants then put a belt on. Still looks awesome!</p>
that is so awesome.. my 5 yr old wants to be a ghostbuster for halloween.. wish I had found this site sooner-- i ended up making him a pack out of a box, paint, air pump tube, glow bracelets (for wires.. he wanted something that glowed) , and a toy gun (he insisted on his storm trooper gun).... this wouldve been waaaayyy better. Oh well.. .time to find the instructions for the goggles!!
Wow, that's awesome! I'd love to see a picture of the costume if you've got one!
could you make like a print out fold template for the wand box?
I don't really have a way to do that, but if I ever come up with one I'll certainly share it here!
Would you consider selling a kids size? My son wants to be a ghostbuster for Halloween but I can't find a good proton pack anywhere. <br>Thanks
yes, please let me know. :)
Hi, I've gone ahead and listed this pack now, if you're interested (and it's not too expensive) here's the link: http://www.ebay.com/itm/230684551098?ssPageName=STRK:MESELX:IT&amp;_trksid=p3984.m1555.l2649
Actually, I'm planning on listing it on ebay in the next couple of days, would you like me to contact you when it goes up?
You are the coolest parent!
Hi, What an awesome pack! I like the price too! I run a special needs camp that is going to need 30 of these next summer.... no wonder I am working on this now. I was wondering how long the total project took? Best!
Hi Dramaplay, glad you liked it! The cost on 30 of them would probably be more per each, as a lot of the stuff I used was cast off junk or things I already had, but I think you could still probably get by on a reasonable budget.&nbsp; If you could get a little support/sponsorship from your local goodwill or st. vinnies you could probably even come in under budget!&nbsp;<br> <br> Total time for this pack was, oh, around 30 hours?&nbsp; I don't know, I wasn't rushing or timing myself.&nbsp; I did it almost entirely in the evenings after work for two or three weeks.&nbsp; One of the nice things about doing a lot of these at once would be that you'd be able to hammer out a large number of each part all at once, getting faster and better after each one.<br> <br> If you need any more help or advice just ask!&nbsp;<br> <br>
thanks, I am really inspired... even have my husband working on it! I'll post when we finish!
ur the best dad in the world
Thanks Pieman, I do try!<br />
It is awesome that you did this for your daughter.&nbsp; <br />
Thanks atombomb.&nbsp; I&nbsp;had a good time doing it and she really enjoyed the costume.&nbsp; I think the one down side was that she spent a lot of time explaining it to other kids.&nbsp; All the grown ups knew what was going on, though!<br />
Who you going to call GHOSTBUSTERS!!<br /> Neat
Thanks J-Five!&nbsp; Please vote for me in the Halloween contest!<br />
&quot;Sewn by a drunk.&quot;&nbsp; HA&nbsp;HA&nbsp;HA!<br /> <br /> We should start a group called &quot;Parents that spend too much time on their kid's Halloween costumes.&quot;&nbsp; Then again, we're already all here on instructables, so it would just be redundant.&nbsp; Nice costume, your kid is cool.<br />
Thanks a lot seamster, I'm glad you liked it.&nbsp; Did you see the picture of those seams?&nbsp; They were AWEFUL!&nbsp; I can't believe it held together.<br /> <br /> <br />
So they were a little rough, but who's going to notice?&nbsp; <br /> <br /> Most people would avoid pointing out things like that, but that stuff is great to see.&nbsp; It's nice to laugh at ourselves, and I&nbsp;really enjoy it when people include their own clever self-commentary in their instructables.&nbsp; <br /> <br /> I&nbsp;wish more people would do it!&nbsp; <br />
&nbsp;Sweet! &nbsp;That looks great. &nbsp;Go India!
Thanks Matt!<br />
$15.88!! That's awesome....<br />
Yeah, I was surprised I had so much junk gathering dust in the shop!<br />
