Building a business is a lot more work than hacking on some fun ideas. There is significant risk, often little chance of a payoff, and it consumes everything in your life. IMHO there's nothing wrong with working for other people from time to time and being apart of a community of engineers.

As an aside, these sound like awesome projects and it sounds like you accomplished your goals of creating and learning from new experiences! I wouldn't call them worthless but rather adventures! That 3D printed watch is neat, I've been trying to come across a new kind of PC for the year 2020 and beyond which acts as a hub. There are all sorts of exciting stuff on the horizon that you can continue to explore like WiGig and beyond. Don't give up!
