Have a bunch of records (or books, games or any other media on a shelf)? Then you’ll want to check out Hackaday user Mike Smith’s organisation project that allows him to find a specific record using the power of LED lights.
The idea here is simple. Smith searches for a record and the LEDs light up to tell him exactly where it is. Obviously there’s a lot of prep here to get it ready, but the end result is pretty amazing system for finding what he needs. The project uses a Raspberry Pi, a set of LED strips and a few other parts. While this build is specifically for tracking down records, there’s no reason why it couldn’t be used for anything else. It’s a complicated project to be sure, but you’ll find all sorts of help over on Hackaday.
