First time building a hardware product - where to start?
I have an idea for a small electric car accessory. It should be overall pretty simple mechanically - mostly off the shelf components, 12V or battery powered. There are products in other categories that are somewhat similar so I can tell it's definitely doable but nothing exists for the purpose that I am trying to build.
I have worked in startups before but always had budgets to work with while I am still at a research/ idea stage and don't want to invest a lot before I have some progress. I would love to get feedback from users but even for that I need something to show. I also think Kickstarter would be great - what progress should I aim for to launch a kickstarter campaign? where do I start?
