This video is an amazing time lapse of the creation of a Eurorack synth module. It shows you what you'll spend a lot of time doing in a smaller org (smaller, as in, you do everything...). https://www.youtube.com/watch?v=1pawXfoTg1k
Wow that was mesmerizing. I'm surprised that all of the traces were drawn manually. I had always assumed that modern design software would do all of that tedious stuff for you.
The creator of that video was answering questions on reddit, and amazingly the whole design and build process took less than a week.
