This is super cool! > I taught myself circuit board design and found a niche market that I designed a few products for that sold like gangbusters with zero marketing for a few years until the market cooled off and low cost knock offs started entering the market. Can you elaborate a bit? Did you teach yourself literal circuit board design (but already had a background in electronics/hardware)? Or did you start from scratch and learn how to design an electronic circuit? What was the niche (broadly?) > In hind sight the best way to find these kinds of opportunities is not to be looking for them. You really just need to get a really deep understanding of a hobby or industry or market that interests you in some way and once you have that then these sorts of things kind of pop out of the woodwork. 1000% agree. The single best way to find an idea is to be seriously and deeply involved in a hobby/area of interest. There are so many ideas out there screaming you in the face.

It was a bit of both, My degree is in CS, I only took one EE/hardware class in school that was more about programming CPLDs than anything else. These days really all you need to know math wise to build simple stuff is V=IR and P=IV, things everyone learns in high school physics class. Everything else you can usually get by looking at the reference circuits in data sheets or looking it up as you go. The hardest part for me was finding the time to get over the learning curve of the PCB design software, in my case I learned EagleCAD. After I did that and formed good habits with how I used the software I now able to do some pretty complex stuff. The limiting factor now is probably that my ambition has outgrown the software I learned. The niche was building adapters for old server power supplies so you can re-purpose them for use as general purpose 12 Volt power supplies. It was a thing in the RC community for a while to charge batteries but it got really big in the 2014 - 2017 time frame due to the Bitcoin mining industry needing low cost high wattage PSUs.
