Update on Windows IoT version.
2 day in and I have it all plugged in and working with a basic UI.
Windows IoT is surprisingly easy to work with.
I had problems with my 8 channel 5v board.
Turns out it only ran with 12v! So that is powered off a PSU now.
I ping claymore port, then turn relay on if no response.
I had to check firewall settings for claymore too, that gave me some silly problems.
