I was wondering what would be the best way to post on HN or another platform a kind of a blueprint for an idea? I'm in the ideation/design phase of a nylon-based linear actuator project and would love to gather some feedback from people (semi)-related to any adjacent fields that could give some additional feedback on the theoretical/practical side of the product. I guess it would fit "Ask HN" best, right?
