Hardware Startups: Solve hard problems
Welcome to the Hardware Startups sub-Reddit - feel free to post on anything that you think will interest anyone in the community. The idea is that we're a blend of r/DIY and r/startups content - like a Hacker News for hardware. Good ideas: hardware news, prototyping/manufacturing how-to, success stories, physical Kickstarter pages, etc. Bad ideas: General startup stuff, DIY articles without a startup angle, TC/VB/etc. link-bait, etc.
