May not be exactly what your looking for but bolt VC posts some really interesting content around starting hardware companies. https://blog.bolt.io

Theres a whole series on the hardware process: https://blog.bolt.io/ideation/ https://blog.bolt.io/design/ https://blog.bolt.io/engineering/ https://blog.bolt.io/validation/

They also have a bunch of great posts on strategy and business models.

Hewlett Packard[0] is interesting. I'm sure one could find companies for which the place was called Silicon Valley.

You could also check out Shenzhen and ask Andrew Huang.[1] Apparently, hardware startups there move really, really fast.[2]

He also has a book entitled "The Essential Guide to Shenzhen", here's a thread about it.[3]

Depends on what experience you have in the field you target, and more importantly how large (in physical dimensions and technical complexity) the hardware product you want to develop is?
