Clock Overclock

The circuit board inside this clock died, so I replaced it with my laptop. You could say that the clock speed is about 70x the standard speed (this is the fastest the mechanism can handle before it just oscillates) – I’m impressed it can handle this.

The headphone output is connected directly to the coil in the clock movement and driven with a square wave. The coil is 250 ohms – some headphones are much lower than this, so there’s no need to worry about damaging the laptop’s headphone output, either! The gears, on the other hand, may wear out a little quicker than usual. =P
