Thanks to Lior Elazary for sending in this great project. It accomplished a few things, he was able to justify the purchase of a laser cutter and his kids learned come computer basics. His Mechanical Bit Adder Clock is sure to be built by many since he also made a detailed Instructable for it.
“The inspiration for this project came from trying to teach my son and daughter about how a computer works (in reality, I was always fascinated with mechanical computers and clocks, but I had to give a better excuse to my wife for buying a laser cutter specifically for this project).
The Mechanical CPU Clock shows the basic building blocks of a CPU (ALU.Buses,RAM,registers, and a Control Unit). It executes a set of instructions which will emulate a simple wall clock.”
