Building a clock the hard way

[Steve Simpkin]

I am fascinated by time and clocks as well. When I first discovered WWV broadcasts around 1973, I would use it weekly to synchronize every clock and watch in the house. I also remember buying a clock chip and PCB from Radio Shack to build a LED clock. For my Senior Project in 1984 I made a talking alarm clock. I used a 6502 uP with a General Instruments speech chip that was preprogrammed with a limited vocabulary needed for a clock. My future wife at the time did most of the wire wrapping. It all worked!
