Title: Req: 2 Way Door Phone / Intercom Post by: charudatt on August 19, 2009, 10:21:26 10:21 Hi,
I am looking for some ideas on how to make a 2 Wire , 2 Way Door Phone / Intercom. I have successfully built a Simplex one using Silicon Chip article, and now I am wanting to make a full Duplex one. Any one having any idea, please share. regards Title: Re: Req: 2 Way Door Phone / Intercom Post by: hexadecimal on August 19, 2009, 11:28:51 11:28 http://www.electronics-lab.com/projects/telephone/014/index.html

Go crazier and implement full-duplex intercom with noise cancelling. :-) Yes, is overkill, but bragging rights are good. |
