Space-wide intercoms

[croepha]

This may be a bit ambitious, and might need to be done in stages over a long term, but I would like to have multiple push-to-talk intercom stations spread through out the space.

Some general ideas:

• Provide space-wide public addressing like "Im making a pizza order, who wants in", or "pizza is here, come and get it"
• Provide a way to have short conversations across the space, like "are you done with that tool, I need it here"
• function as a doorbell
• Function as a street intercom like "Sorry we're closed, come back tomorrow. / But.. We have pizza, let us in..."
• We could have like two local channels, one PA channel, and one street channel

I think this would make a fun hack/diy project for medium to advanced electronics people

This could also be nice as a light. So, instead of a sound you can just see a light blinking: three times means someone at the door, etc.

Nice idea. Mumble would be a good base to build this on. Each location would be a mumble client, connected to various group rooms.

There are options for groups and sub groups so that you can structure the areas of the space as well as having a global channel for PA mode.

There's even a headless raspberry pi walkie-talkie codebase to build on.

@SuperQ thanks for the research material! I suspect that an analog approach might give a better experience in terms of reliability and quality though, but we can build some prototypes and compare them
