If you’re looking for a 1-second time reference, you’d probably just grab a GPS module off the shelf and use the 1PPS output. As demonstrated by [InazumaDenki], though, an old quartz cl… ...

Sure enough, there was a sharp-looking analog clock in the middle of the faux-wood dash. Generally, quartz timepieces from Ford products of the 1980s will work, so I didn't bother to test it.

Nowadays, with digital clocks and quartz clocks, we’re spoiled—everything is maintenance-free, and once it stops working you throw it away and get a new one.

Because quartz crystal oscillators are inherently “custom,” MEMS clocks are usually much cheaper and faster to produce. Also, MEMS are manufactured in very high volumes using semiconductor ...

If the clock is using a wall wart that converts AC to DC then it is not tied to mains since the DC doesn’t have a zero crossing to count. It’s possible you have a wall-wart that converts AC-AC ...

Clocks that have been affected the most are those digital alarm clocks and in ovens and microwaves as they use the frequency of the power grid to keep time. TNW writes that the power grid in ...
