The cheap electronic metronomes are just a 555, some passive components and a rotary switch. Diagnosing and fixing one is a really good project for a 10-15yo

It does sound fun. But, it'd be a project. Now imagine you had no manuals, voltmeter, or replacement chips. What's a 555? Not so fun now.

Or imagine this another way. You have all the docs, and a fully stocked electronics lab. And in the other corner is someone with a screwdriver and a broken mechanical metronome. Who's faster?

Without a set of watchmaker's tools and the patience of an adult-- those coil springs and gears are pretty frustrating!

BTW the digital one I have has no moving parts; it has buttons to select the bpm and pattern from pre-programmed options.
