Hey everyone, I am trying to find niche forums where people discuss the design of and review hardware products.I am talking about people building the next roomba or personal trimmers. I am looking for something between HackerNews and ProductHunt for hardware: where I can get opinions and discussion on the design, components, techniques etc, but where also I can learn from people "launching" their products, and hopefully do a launch of my own someday. If you've felt any of these needs met at any of the forums you visit, I'd love to know.

I had a cursory look at Hackaday, but implicitly it seems to be geared more towards electronics.
