    dear Prof. Raldi

    What kind of methode for temperature control for your incubator? In Kick Andy programme, I interpreted that it use on-off methode. This methode yields oscillating temperarure around targeted temperature, and may give stress to the baby.

    If that true, may I contribute a simple circuit for temperature control? It works propotionally, the heater (bulb in this case) get dim if the actual temperature getting close to targeted temperature.

    It works smoothly. When I test it, I set 40 centigrade target and the temperature varies between 39.9 to 40.1 centigrade.

    In that test, I set 40 centigrade because I intended the design for chicken-eggs incubator. But it can be set above room temperature to 99 centigrade.

    I hope you answer my offer. I need my knowledge be able to contribute kindness for mankind.

    Sorry for my terrible english. Thank you.

    sincerely yours
