NixieStat

2nd whack on the display board. Not sure where my head was with the first try, the nixie foot print was wrong and the anode drivers were just all wrong.

I still have a small fix on the cpu card itself, but I will hold that fix off for a bit. It was nothing an X-acto knife and a jumper didn't fix. 

I will be submitting the board changes to github as well as changes to the code to ease configuration.

Finally have a working prototype for version 2 of the NixieStat. My older AVR based version sied last year so I updated it. Some might say over engineered it ;).

This new version is an ESP32 based system with remote sensors. The system uses the Mosquito MQTT bus running on a RaspberryPI to handle feeding the data from the remote sensors to the thermostat itself.

Since my first priority was getting a thermostat that would keep my house comfy, don't have a display for it yet. Since my nouse is now comfy, I am starting on the next step, the User interface.

The source, including code and hardware drawing is now in github.com. The code resides in 2 repositories croftj/nixiestat and croftj/esp_components.

Documentation is quite sketchy at this point but will hopefully get better as time goes on.
