I’m not really sure what to write here. I have thought of couple of ideas of how to have a switch that didn’t require hands. They probably exist somewhere out there, but my ideas are being able to have a switch that operates when there’s a vacuum vs in open air, kind of like a vacuum detector. Then there’s the idea of operating when there is water vapour where you blow into it, or kind of like a humidity detector, where it can be prevented from activated when it’s dry wind or something.
The video about Red Burns was really inspiring though, gave me a new drive to stay in the class.
