To Be
Allen E. Rhodes
I was on the ranch in La Salle
County where I hunt, about 100 km south of San
Antonio and was collecting dead limbs for firewood.
It was relatively early, around 9:00 AM.

Crystal
controlled 1 pulse per second clock.
Allan Rydberg
This easy to make circuit will provide
pulses at a highly accurate rate of
one per second (1 Hz).
The circuit is based
on a common quartz clock movement that
seems to be in most of today's wall
clocks. A suitable movement can be salvaged
from a clock or purchased new from a
hobby shop.
