Description Phone system for fun, at Make Muncih 2017

The basic idea is to have some old rotary dial phones spread around the Zenith during the Make Munich. Everybody should be able to talk to anyone who picked up a phone anywhere in the hall. It would also be cool to trigger some actions by dialing a specific number.



  • 4 rotary dial phones
