Hello, I'm new to this forum and I hope that I can find some help and not irritate the knowledgeable electronics experts too much with my questions. A bit of background: I am involved with a group that is doing work on a small private church run school in Belize City, Belize, C.A. and they could really use an intercom system. After pricing new ones and looking into used ones from local school systems, I determined to look into making one. Can anyone tell me where I can find a design with materials and schematics for a simple intercom system? I have novice electronics equipment and abilities, but I need help. Thanks in advance. :)
