alarm switch and clock mechanism (quartz movement), etc. Next wire the circuit as shown in the schematic diagram, observing correct connection points and polarities, and power it from a 5VDC supply.

so you can “hack” a quartz clock to get a timebase generator, which can be used in any project that needs exactly one-second pulses.” Check out the full instructions (including step-by-step photos and ...

The evolution of precision clocks. The tradeoffs between ... Figures 1a and 1b show block diagrams of a MEMS oscillator and a crystal oscillator circuit. The MEMS oscillator is more complicated.
