This is a stun gun-like device disguised as a deodorant stick. It was built out of cheap components from Ebay, an Old Spice Classic plastic container, and some hand-moldable plastic.
Unfortunately, because I did this project a while back without any thoughts of sharing it at the time, I don't have any pictures of the process. However I took some pictures of it pulled apart in an attempt to show how it was assembled, and I also drew up a schematic of the wiring for clarification.
