What do you use to track small things in your home so they don't get lost?
1. Buy a lot of things, and hope that not all of them will be lost at the same time. Every time I make an amazon order (about once a month), I buy an SD card and some rechargeable AA/AAA batteries, always. I have like 10 nail clippers, 8 scientific calculators. I have around 3 pens for every sqft of my home, sprinkled around everywhere. But with more expensive things this scales badly, gotta admit.
2. You know those gigantic keychains on the toilet keys? I try to do the same, with some of my things. Also, nail/glue them to a fix place. My AppleTV remote (that crappy Siri one) is lives on a clipboard with double-sided tape - I got bored fishing it out from between the sofa pillows. My USB current/voltmeter is tied to my desktop PC with a piece of string...
