How would i build a cheap wireless theatre comms add-on, possibly using phones as the wireless component?
My school theatre has a Jands Ezicom (i think) comms system but its all wired. My friend and i were wondering if its at all possible to make a DIY wireless add-on. We had the idea of somehow interfacing some cordless phones into the system and using the conference capabilities of them but obviously this presents some problems with voltage/impedance/whatever else. Its also just a personal thing so A) only up to 2 wireless devices would be needed max, and B) its self funded so cheaper is better. If anyone can offer advice or ideas its all welcome.
