LVL1 community member Tim G. and his wife created this great ghostbusters costume for their son Harper.
I have attached the schematic for the proton pack lights. I used a 6V lantern battery as part of the pack so I didn’t need a voltage regulator. The flashlight has a separate 9V battery located in the gun and 6 white LEDs.I used these plans for the pack: http://www.gbfans.com/equipment/plans/norm-gagnon/ although many parts had to be swapped out for similar items that were half the size.The main structure of the pack is made from black coroplast since I had some on hand. In fact I made the whole pack aside from the straps using items I had lying around. For sounds I mounted a small mp3 player on the gun and used the 6V battery to power a set of USB powered PC speakers.
