I saw someone had a question a couple of years ago about connecting his intercom (which used a phone line) to a rPi and none of the answers were realistic. I also would like to do some simple project but without using too much additional hardware (eg, no readymade landline intercom) which transmits in a way that is readily available and cheap. I was thinking of having some simple FM circuit connect to the GPIO and transmit that way, with packet audio.

I am not new to rPi and have skills with soldering and basic electronics and think this would be a great project for short range (and legal) telecoms between two rPi Zero W's.

I realise also that using external FM transceivers could be extraneous and perhaps its possible to do it via built-in WiFi, saving time and money. It would require a mic and speaker thought but they are so cheap.

Any inquiring minds welcome to comment or criticise! I did do a decent search for this idea and didn't find anything that was what I was thinking about...as I mentioned earlier someone mentioned using Asterix which IMO is overkill, given the simple task required. I couldnt reply on that original query as I am new here and don't have 50 points.

PS posting a simple question on this site is difficult to do when you are new :(

    I'm surprised you only seem to refer to one question a couple of years ago and allegedly only asterisk was suggested - searching the phrase "raspberry pi intercom" results in many such projects, and not one I've looked at even hints at asterisk Dec 17 '18 at 21:55
  • "allegedly" like I committed a crime. Lovely response! Original question not posted because I assumed I couldn't post URL's. Not sure why my simple question made you confrontational though. Perhaps this community isn't for me. here: raspberrypi.stackexchange.com/questions/13800/…

  • allege: to assert without proof - you posted no link in your question - therefore, no proof - please, don't infer I was accusing you of something sinister, perhaps my use of the English language is inelegant compared to you, for which I humbly prostrate myself before you and beg for forgiveness Dec 17 '18 at 22:37
  • Perhaps something could be cobbled together using netcat? Have a look here. Dec 17 '18 at 22:39

    this seems to be the best solution I think: projectable.me/…
