I am attempting to make a Buzzwire game project. This is a shaped metal rod that a person carefully navigates a circular wand without touching it. The goal is to reach the other side of the wire without touching the wand to the wire. If you miss the wire then it will make a buzzing sound.
My objective is to make a large, human-sized curvy shaped stainless steel tube which will be mounted into the ground. The idea I have is to avoid wires and have all the electronics incorporated into the handle of the wand. I want to incorporate a speaker in it with a circuit that can detect metal to metal contact anywhere around the hoop. No optical devices, no proximity detectors but simply detect the increase of metal mass in contact. This will be used outdoors in the bright sun so it has to be rugged, battery-powered, possibly solar-rechargeable, durable and simple for less parts to break down.
Any ideas how this can be accomplished? I am trying to find some way to not have it accidentally triggered. The hoop may be stainless steel as well. Any help would be appreciated.
