We picked up some eggs on Sunday the 28th August and put them in our home made incubator. I took a one wire temperature sensor and connected it to an AVR micro controller and a solid state relay. It simply turns a 40 watt light bulb on and off as required to maintain a consistent 37.5 degrees Centigrade.

As for turning the eggs, we’ve got the eggs supported in a cardboad egg tray and we’re just tilting the entire incubator with a wedge of firewood.

We’re trying to turn them five times a day at 6am, 10am, 2pm, 6pm and 10pm. An odd number of turns means they’re not on the same side two nights in a row.

The eggs are due to hatch on the 18th September.
