Watch Timer circuit

Posted on Feb 7, 2014

Hello all, I ran across this schematic for a watch timer in a hobby electronics book. Anyone built something like this before? My knowledge of electronics is somewhat limited. Here is the description: ``This circuit adapts a frequency counter to measure intervals, watch ticks are clipped and shaped and formed into a square wave. This square wave is used to gate an accurately known clock (1 Mhz TTL XTAL OSC) and an external counter is used to directly count the clock pulses during the..
