I also produce hardware projects and share them open source but unfortunately at a certain level of complexity people don't reproduce them. It's kind of sad but also I'm glad to be able to give back as I've had people help me learn to code in the past, sit down with me through video and yeah. Or people sharing knowledge in question answer forums.
There is the inspiration aspect too I've had some of my repos get forked/modded so that's something but yeah ultimately gotta do it for yourself. Getting published in tech websites is cool though, like I had a project get picked up by a Japanese website that was neat.
