Recently I decided to make a communication system throughout my house (electronic free) so I decided to make a system of tin-can telephones. I realized quickly that it would be difficult, though, because they don't corner well (or at all). So my first idea was to make what I called 'repeaters', and you would put one on the corner. It was just another can, but it had two strings attached, so it would forward the vibrations. That was very difficult to make. I also wanted to make hubs that you could connect to, so multiple people could talk to each other. So I settled on just a loop of string that would be kept tight. But the issue with that it has to do this:
0 / \ / \ / \ / _____]__ / | ] | | | ] = can |_ = wall / = string 0 = hub
It has to go way out past the corner, and then come back, which is a big waste of material, and it lowers the quality of the sound. So is there a way to do something like this but make it go right around the corner? I don't want to have to set up a chair or anything, because I have this running along the floor (it's sort of out of the way). Maybe I could prop the loop away from the wall a bit, then hook up? Thanks in advance!
P.S. If you're wondering why I'm doing this rather than just walking into the other room, allow me to elaborate: Sometimes when I'm really bored I like taking some simple experiment (e.g. a pinhole camera), and taking it to a crazy level (e.g. turning my room into a pinhole camera). And while right now I just have the cans going around a single corner, I'm planning to elaborate and spread to different floors.
