I have officially ordered the first versions supplies and hope it will all come in before Halloween so I can set it up for Halloween.
The KiCad files can be found here: https://github.com/PhysicsUofRAUI/decoration_control/tree/main/ecad
I did make a custom symbol and footprint for the relay, and if people are interested in seeing that I can make a separate repo to store all my custom symbols and footprints.
I have also entered all the components to the project page, but have not yet added instructions since I have not yet made one.
Watch out for my next project log sometime in October 2021!
