Hi All,

yesterday there was a request for an Intercom/Door Phone circuit.

Audioguru suggested a full duplex intercom, which I already had refined for my personal use. (No Thai is supposed to use a push button or a potentiometer since they usually destroy them pretty quickly.)

The circuit schematic and PCB layouts are easy to read. Despite that I received three more emails asking me to explain connections between "master" and "slave".

Today I received another mail asking for a circuit extension to connect to a PC sound card. (No word about that in the foregoing thread.)

Well, I worked in the extension and sent the revised circuit to the OP.

I wonder what he'll come up next with.

Probably a suggestion how to convert the circuit into a self propelled triple-A gun? :rolleyes:

P.S. For everybody asking for circuits of my design: My rate is US$250 per started working hour. :)
