The main problem with DIY incubators is temperature control.
I have seen so many type of temp control, I can testify to
PID. Proportional-integral-derivative
controllers are cheep, cheaper than most temperature controllers you can by
from any poultry supply house.
Ebay is loaded with them.
And you can purchase them with a thermocouple and relay, to control any
type of heat source.
The advantage to a PID controller is that it learns. As the temperature swings up and down,
it measures time against rate of rise and learns just how long to hold on the
heat source. The temperature
reading can be calibrated to within .5 degrees, thus maintaining accurate
temperature control.
So, check out Ebay, search PID controller and take accurate control over
your DIY incubator project.
