[WilkoL’s] clock though has a most unusual clock source: a 440 Hz tuning fork. A cheap plastic dome really shows off the fork and contributes to this good-looking build.

I assumed the latter, but felt further experimentation was called for. Back home, I bought my own tuning fork (pitch of A, 440 Hz) and started carrying it around to bars.

So while most tuning forks sound the note of A = 440Hz, this mini version is apparently tuned to 4,096 Hz – about the pitch of the highest note on a piano (C8). Read more: This video of a spinning ...

Have you ever seen a tuning fork at 10,000 FPS? Small clarification: the large fork has a 180hz tone when analyzed with a frequency detector (and held up to your ear), but also higher overtones ...
