Haha, love that story. Reminds me of another student who was going to build a digital clock that only displayed the time, very accurately, in 15 minute intervals. Because, he reasoned, nobody should need time more accurate than that!

I, too, built a CMOS digital clock for a freshman lab project out of about 40 chips. It did not work, it just blinked the display LEDs erratically. I still have it, it still does not work and I still don't know why.

My senior EE91 lab project (single board computer) did work, though, but I misplaced it somewhere in the last 40 years :-(
