Pictured a Beagle Bone Black running Debian with a python mqtt subscription to control two relays via the custom shield I built with a couple FET transistors (with room to expand to 8 total).
Have you ever spent way to much time fixing something based on an assumption that you never question again? At least four wasted hours. It was some loading in the relay! bleuch. I replaced FET transistor a couple times and a resistor before realizing there was something funky with the relay drive.
Working prototype
September 13, 2015
Pictured here is a Windows 10 client I built that reads sensors, in this case DS18B20 temperature sensors, and controls for switches. The win10 client is a universal windows app deployed to my desktop, a tablet and hopefully real soon now a windows 10 phone. I used MvvM Light view models and Messenger and utilized the new compiled bindings available now with win10 visual studio 2015.
I made an animated .gif of the HomeAmation.Mqtt app in action.
