I made some redstone contraptions and i also assembled some that mr.crayfish posted and there is a massive tnt cannon i didnt make but other than that i hope you enjoy.

i made this in a build off battle against a massive noob and the time i put in i would hate to not see this uploaded so here it is. This map is for 1.8. it is incomplete. a ton of work went into the redstone in this build so please don't dis.

Please try it i put two hours in to it. it is modded and this is the technic pack i used on my server http://www.technicpack.net/modpack/details/skooler-kids.321630
