I am working on an automatic humidity controller for incubation. I can look at two types. The first would be mounted inside an incubator such as the Dickey or Sportsman. The second would be a free standing unit that could be mounted to any incubator. It would be as simple as dialing in the humidity you want, then sitting back and letting the unit manage it. Currently, the costs are looking to be around $150 or so just for the bits .... so figure retail from there. Anyhow ... If I get this done I'll tell y'all how I did it. If there is a market, I'll sell them.
