Sometimes ago I found a pair of airpods on a pavement in my city. I started searching for the owner nearby, but nobody showed up, after I keept them in a drawer for a while hoping that the owner would enable lost mode, but they didn't. After 10 days without news I disabled location and started to use them. They are still thetered to the original account. I would be happy to return them, but the owner probably don't know or don't care..
Beside the classical setup of homeassistant I have a telegram bot that parse the website of a local used camera gear. Sometimes you can find good deals, but they last a couple of minutes, so having the new deals on time is vital.
Cameras may be obsolete, but old camera lenses can be adapted to modern mirrorless cameras pretty easily, and usually they last more than camera bodies. There are some 70s/80s ones that are pretty decent even for modern standards, plus they have a look that modern lenses don't have.. so prices are rising..
