From my forays into electrical I had some ideas for making trap bases.

The first step was trapping someone inside my trap base. This is pretty straightforward, I would leave a locked door open tempting people to enter. Once they do they’ll trigger a pressure pad hidden underneath a rug. The funny thing about pressure pads is that you don’t actually have to step on one to trigger it. It could be underneath a stairs, on a floor you’d bump with your head etc. The pressure pad triggers the door controller to close using a handy memory cell.

Once that happens I have a timer hooked up to a Tesla coil (water base), flame and shotgun traps if I am using hidden doors etc etc
