A two in one Article: Very good description of how to build an incubator, including a diagram how to wire a light bulb to a thermostat and how to build a simple egg-turner. Not automatic, but simple and you can turn the eggs without opening the 'bator. Nice pictures, but they could be larger.
Thank you for all the pictures and the explanations throughout the article. It was also nice to read about changes you had to make through out the process.
