> No, you will not accidentally meet real-world safety standards with your project by dint of your sterling virtue, high intelligence, wisdom in the ways of the world, and impeccable engineering skills. Nor will you do so by adding a couple more features. Safety is the result of deliberate processes.

This is unnecessary condescending snark that I hope we see less of on HN. Everyone should be open to criticism, but how does that encourage the inventor?

There is no invention here, and nothing to encourage. Electrically operated doors date from the 19th century, and we have over 100 years of understanding of their hazards.

> nothing to encourage

Absolutely there is. You and I both agree we should encourage them to learn properly, experiment responsibly and proceed with safety in mind.

> There is no invention

I regret that you ever saw the word "inventor" and couldn't think past it. {Creator, engineer, maker, hacker, killer} Pick whatever word it takes for you to ignore the noun and focus on the idea and better way forward.
