And that is the result . 14 chicks of 25eggs ,but i could say that was 100% sucess because the other eggs were not fertilized. not even a single dead before or after hatch. Its not the arduino the most versatile machine? :)
i found that the incubator with 2 fans its quite accurate , i check all...
There it is my chicken eggs encubator .
Made from a 25 liters plastic storage box and some foam outside to prevent heat loss.
i used 2 X 18w halogen g9 bulbs and a 230v dimmer to decrease light brightness.
There is a diagram above from fritzing. I uses an main arduino that controls a SSR relay...
