Re:Show HN: I've built self-opening trash bin, I relax mysel... by crearo on Tuesday September 01, 2020 @06:05AM (#24340094)
A better, possibly fast open/close design would be:

1. to have a motor roll open and close the bin lid.

2. the opening end could have a weak magnetic strip to "click" on that side.

3. to have the sensors to the side of the bin instead of on top.

4. my bin is under the kitchen sink, and I'd presume you'd want to hide your bin too, and so you could use a simple light sensor there.

All this would make it a simple yet super effective solution to avoid the bin fanning out odours.
