Sometimes low-tech is a cooler solution than high-tech.
This sensor device detects if your package was handled roughly during transport: no electronics, just clever engineering.
@polychrome My favorite example of this kind of thing is the flush toilet. I remember when I was a kid the power went out and I was surprised when my parents told me the toilet would still flush. If someone were to invent the toilet today it'd definitely require electricity
Another one is the mechanism that makes the gas pump shut off when your tank is full, which is also non-electric - only because it became necessary before reliable sensors for that kind of thing were invented
@polychrome I've always loved these tracking stickers! The shock ones, absolute temperature, and time-temperature ones are pretty simple tech but refined to a fun degree.
@polychrome okay but serious question i’ve wondered about since first seeing these in college: how do you ship these to the origination point in a way that they’re not pre-ruined?
