Popular Electronics DIGI-VISTA
A True Electronic Digital Clock
By Charles G. Kay and Daniel Meyer
The digital clock was one of my first design projects for Southwest
Technical. I was still in college at the time. I worked at SWTPC two or three
afternoons a week during the school year and full time during the Summer and
holidays. I was home one of those afternoons that I usually worked because I
just had a dental procedure done. I had called in sick which was rare for me.
The doorbell rang and it was Daniel Meyer. He had driven over to personally deliver
a $500 check from Popular Electronics as payment for the digital clock article.
I was shocked! Very few college students are lucky enough to have their part
time employer drive over to their house to hand deliver a check for $500. It
meant a lot to me at the time and is something I will never forget.
