Butterfly ?? I dont know that type but as long as its vented. As chickens develop they start to produce metabolic heat so it needs to able to be opened although a good thermostat keeps the heat more even.

The temperature will rise and fall with any heater element so as long as the peaks and troughs are not to wide that doesn't matter either. Its the average temperature over time that is important. The idea is to warm the eggs so you dont want a heater so strong that it cooks eggs. Another point is that an egg is a real heat sink. It will take at least an hour for the core egg temperature to move even half a degree. Also you need to be measuring the temperature roughly about half the height of an egg on its side.

Computer fans work fine on full power. It is moving the air at a certain temperature around the incubator and not forcibly extracting or drawing in air.

I think I'll just cut a hole somewhere for the air vent and use a piece of flat plastic bolted over the hole that can pivot to cover or uncover the hole.
Not sure when my bits and pieces will arrive so I'll start working with what I have tomorrow :-)

My fan arrived yesterday so I got stuck in with the fan controller. I may not need the fine air flow control but I had already planned to build it and had purchased the components. I have not done any electronics before but I do own a soldering iron from when I replaced a 12v car fridge plug a while ago.
I made a mess of my first attempt with the first two components I soldered on so turned the board around and started again.
The components and board to solder to cost around $4 and I got to learn something new and have some fun!
Surprisingly the circuit worked first go and the knob adjusts the the fan speed from full power down to very low when it was connected to a car battery.
I have to wait for my 240v-12v power supply to arrive before it goes into the incubator but it's ready to go.
Maybe I'll splurge on a nice cover for the knob rather than the bare metal.
I will probably build the egg turner next but am also waiting for the motor and timer for that to arrive.
So far I'm happy to get the project kick started!

Great that you got it working how you wanted. Always nice to have that happen with a project.

I've now added my egg turner timer circuit to the board. The two little blue and white boxes are the adjustment for interval between turns and hoe long the motor will run to turn the eggs.
Still waiting for the motor to see if it works properly.

Bits and pieces are finally arriving! Have the heater, temp controller and motor.

What are you using for the housing of the Incubator???? One idea, and evidently they work exceptionally well is an Old fridge (gutted of course) with a round top, if you can still find them.

Another tip is use a ceramic heating element, they are easier to control and usually do not have the over run of normal heating elements.

Hi Ashy,
I'm planning to build a new kitchen for my house so I built a practice cabinet. I will be using that plus insulating the interior.
The heater I have is a mini element that I will blow the computer fan across. Hopefully will do the trick!
Meanwhile, my rooster has just come of age we have noticed so Irma's re-motivated me to finish the project!

Nearly finished!
It's all put together inside the cabinet. The egg turner I think will work OK. Only problem is that it basically turns the eggs a full turn instead of half a turn each time the timer kicks in due to limitations of the timer. I'm hoping it will serve the purpose well enough though.
The only other issue I have at the moment is that I am using a heater that is a tad small for the space. It's freezing cold at the moment and it really struggles to get to 38c with the ambient only being 12c so I might have to wait a few weeks for warmer temps before getting humidity correct and trying my first batch. I should have either used a smaller/more efficient space or got a 400w heater. I guess I could always add another heater.

Looks great. Try testing it after adding some thermal mass - bottles of water. golf balls etc. It may help stabilise and maintain the heat (as eggs would)

Thanks Sue. I've also considered lining the inside with foil or a space blanket as an option.
