Building and tutorials on weapons?

i get really bored during the summer so i have decided that Lowe's is my new favorite store. i build weapons and stuff when im bored like claymores, flamethrowers, tasers, air-soft guns, potato guns, catapults and many other things. i have ran into a problem though... i don't know what to build. normally i would get ideas from people like kip kay, house hold hacker, greek gadgets, and trassa but they don't upload very much. can you please tell me some names of people that do this kind of stuff (w/tutorials and supplies) thank you much appreciated.
