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

- titzer 9y ago> 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?
