Due to recent events (I became a dad a second time 🙂 I revisited my audio baby monitor project for Raspberry Pis called Pifon. The former setup of having one Pi observing one room is not enough anymore and therefore the new version adds multi-room support!
Now you can add as many fon clients as you like. Well, at least up to 3 will be shown in the new UI on the LCD 🙂 All others are still handled but not shown.
While hacking the source I almost completely rewrote the XMPP based bots for mon and fon parts and added some nice features along the way: Configuration is a lot easier now and audio streaming was optimized.
Now a direct SSH pipe is created to connect the microphone device on the fon unit with the player on the mon unit. In favor of this new approach the old way of using a streaming server was dropped. (If you still need it then the new config freedom allows you to simple add the necessary commands again.)
RGB backlight negative LCD 16×2 + extras – RGB on black: This is a fancy upgrade to standard 16×2 LCDs, instead of just having blue and white, or red and black, this LCD has full color RGB characters on a dark/black background! That means you can change the character display colors to anything you want – red, green, blue, pink, white, purple yellow, teal, salmon, chartreuse. This LCD looks strikingly good in person.
