I don't know if anyone else is interested in something like this.
I am investigating making my own controller for heat and humidity in my incubator.
The temp control for the LG incubator is so coarse that I've been monkeying with it since Saturday. I'm almost there. A tiny adjustment of the knob swings the temperature 1 or 2 degrees. Can't seem to get 99.5 degrees. I used long pliars so that I could turn it only about 1/8" at the end of an 8" radius swing. I now have it at 99.2, but I'm afraid to move it any more. It could jump (and has jumped) to 101 or 2. It's like trying to drive a car with a sticking steering wheel that only swerves to the left or the right, but you just can't quite find a spot that will make it go straight down the road. Blasted nuisance.
I could replace the temperature setting and fan with an IncuKit for $50.

Quick Overview
Features:
All-in-one thermostat, heater, fan control unit
For tabletop incubators
Proportional digital electronic pre-set (99.5 F) thermostat
Digital display
Adjustable fan speed
Hatch timer
12V DC power (Allows 110V OR 220V Input)
Remote sensor for accurate temperature reading
Controls DC turner motor (sold separately)
Option to power with a 12V battery (connectors sold separately)
Looks great, but does nothing for humidity.
I found a "temperature and humidity controller" on
ebay. This one is for 220v European. It is about $30. They have them for 110 volts American. They are $130. A voltage converter is available on
ebay for $12.

When power is applied, it creates fog. Put it in a bowl of water, plug it in and pretty fog will soon spill over the edges of the water.
People that raise frogs sometimes use them to add a damp, humid atmosphere to their terrariums.
I saw a youtube where this was used to humidify an incubator.
So, here's the scenario.
I bought the fogger. I bought the controller.
My Little Giant is a still air unit with turner.
- Set the LG thermostat to full on
- Plug the LG in to the new controller and use it to turn the heater on and off.
- I have an old computer fan that I installed in the LG.
- Make a trip to Meyers to get the various pvc fittings to make a water sump and reservoir for the fogger.
- Plug the fogger in to the new controller and use it to turn the fogger on and off.
- Monkey with it until I get it to work.
Further posts will be made using the PM function, unless there is great interest in the subject. If you wish to be included, send me a PM.
If I get a bunch, I may post progress in the Indiana thread.
In any case, when (if) I get it working, I'll post the final results on Indiana thread. No sense in sharing it with the riff raff from other states, the running dog capitalist warmongering curs.
The controller won't be here from Hong Kong until October.
