Ask HN: Anyone interested in learning how I bootstrapped a profitable HW startup

I bootstrapped a profitable niche Hardware product as a solo founder. Thinking of creating either some course or an ongoing behind the scenes community where I share everything from start, to launch, to ongoing marketing and development.

Some stats:

- took me total of about $8k to go from idea, prototyping to producing first 50 units

- worked with manufacturing in China for the first time

- took me a year (not fulltime, probably 3 months if it were fulltime) to write all the software and do the design work

- after about 5 weeks I think, I got my initial investment back and am now profitably growing this niche product.

Would there be interest in some of the behind the scenes journey? Pay per month for monthly behind the scenes updates? What would you like to know specifically?

Thinking of monetizing my journal :)
