7400 competition entry: Periodic egg turner for incubator

Do you need an incubator for hatching eggs?  T0mpr1c3 shows you how to easily make a homemade egg incubator:

This is a project from a couple years ago, which I published on the members’ pages at the Backyard Chickens forum: An automatic egg incubator with PID temperature control and periodic egg-roller, built into a microwave oven. The rotary egg turner employed the microwave turntable and a stationary lattice containing the eggs. A timer circuit comprising a 74HC4060 counter and CD4013 dual flip flop set the turntable in motion several times a day, rolling the eggs.
