I can use the timer-motor from a washer or dryer to turn the eggs VERY SLOWLY. They would be shifting from side-to-side about 30-35 degrees, CONSTANTLY. Would this be worse than turning several times a day? It would be very easy to build. I would not need to buy a timer and, better yet, it's easier to wire-up. The power that the tiny little motor will use, must be insignificant, right?
