monicat - ESP8266-based MQTT Happy Cat

OK, so I wanted to play a bit with MQTT. MQTT is some kind of a machine2machine chat protocol, letting devices chat to some kind of chatrooms, whilst other devices in that chatroom are listening. Terms are not completely correct, mqtt calls it publishers, subscribers and topics. You get the point. Think of a botnet. Just with IoT Gadgets. What could possibly go wrong :)

Just playin’ a bit around with an mqtt broker (that is the chat server :) ) and some command line clients is boring. Something has to happen. And when using MQTT as a backend for all sorts of stuff like monitoring, sensors, things, a universal notification device would come in handy.

Again… a box with some lights would be boring….

Today I finished a small side project which originally was just a test how the Housing of the Piratio could look like:


I started a new Project: piratio.

Piratio is basically a Raspberry Pi based WiFI Internet Radio. What makes it special is that it doesn’t use Raspbian but HypriotOS, which includes Docker.
