Well got some of the documentation together on the web based MK14 keys setup and uploaded it and the kicad and arduino files to my github folder
https://github.com/dallday/MK14ESP8266keys 
Any comments welcome - and if anyone wants a copy of the PCB please let me know
Having thought about it it would be quite nice to have a webpage that sent the keys to the MK14 - a bit like doug's page - just using the real MK14. Will need to see if my web skills can manage that
Stay safe
David
