Introduction<\/h4>\n<p>pifon is a project that realizes an audio baby monitor with 2 (or more) Raspberry Pis. A\u00c2\u00a0RPi is running the\u00c2\u00a0<strong>fon<\/strong> part of the project that records a continous audio streams and keeps looking for audio events, i.e. your baby cries and then reports those events to the other RPi called\u00c2\u00a0<strong>mon<\/strong>. There a display shows you the events and also starts streaming the audio from the fon machine so you can hear your little ones immediately.<\/p>\n<h4>2. Features<\/h4>\n<ul>\n<li>Supports multiple\u00c2\u00a0<strong>fon<\/strong> clients. You can observer multiple rooms\/kids<\/li>\n<li>mon has a flexible UI interface and currently supports a <strong>16&#215;2 LCD display<\/strong> with 5 button input to control the monitor.\n<ul>\n<li>Background LCD color shows fon activity<\/li>\n<li>Display shows state of all fon clients and has a clock in idle mode<\/li>\n<li>Control: muting, listening, monitoring, screen blanking, chiming with the buttons<\/li>\n<\/ul>\n<\/li>\n<li>A <strong>simulator<\/strong> written with <a href=\"http:\/\/www.pygame.org\">PyGame<\/a> lets you run the mon on a Mac\/PC, too. An audio simulator in fon unit lets you test your setup easily.<\/li>\n<li>Use an <strong>XMPP based<\/strong> chat server to communicate audio events and allows you to use standard chat clients to read the events.<\/li>\n<li><strong>Low-latency audio streaming<\/strong> is realized by directly linking the recording device on fon with the player on mon by a SSH pipe.<\/li>\n<li>Very easy to configure by editing config files. You can also use this to change the way audio streaming is set up (e.g. use mpd or Icecast)<\/li>\n<li>A powerful Python Chat Bot framework based on <a href=\"http:\/\/sleekxmpp.com\">SleekXMPP<\/a>\u00c2\u00a0was implemented to run the fon and mon part. They are extensible to support more services in the future (e.g. video, sensor data)<\/li>\n<\/ul>\n<h4>3. Build your own pifon<\/h4>\n<p>pifon is an open-source project and you find the full source code on GitHub:<\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/cnvogelg\/raspi\">cnvogelg\/raspi @ GitHub<\/a><\/li>\n<li>A very detailed I<a href=\"https:\/\/github.com\/cnvogelg\/raspi\/blob\/master\/doc\/pifon.md\">nstruction Manual<\/a> can be found there, too<\/li>\n<\/ul>\n<h5>History<\/h5>\n<ul>\n<li><strong>Version 2.0 &#8211; 4.3.2016<\/strong>\n<ul>\n<li>added multi fon support<\/li>\n<li>new audio streaming<\/li>\n<li>rewrote XMPP bots<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h4>4.
