Hi All,

Thank you for all your help. I have ordered an egg tray from;

http://www.solwayfeeders.com/ProductsRe ... asp?cat=83

I thought I should post the link here for others this side of the world. When it arrives I'll build another incubator to fit it along the lines of a design above.

I'll post details of the auto-egg turner circuits and the heater control. Eventually I'll convert it to a MPU and will post the programming and circuit.

Regards, Terry

Hi Terry,
That would be awsome :) Especially seeing your design specs for an auto turner. Often an automatic turner cost nearly as much as the incubator :shock:

Hi Terry,
will be very interested to see how it comes out and as Andy said interested to see the auto turn as I have some ideas as well.
If you have any questions on design feel free to ask.

regards
Trev

Thanks Caladenia,
While there are a few things that I would do differently, and I also plan to make some changes to the egg tray and turning setup, I am very pleased with the result of my second attempt.
I now have grand plans stewing away for a multi-tray unit IF I can scrounge the required materials (yes the scottish heritage shows, I am tight if I can be)
I also am chewing over a way to setup a auto turn and I am thinking of a purpose made hatcher so the incubator has no down time.
I reckon to go out and buy all the material to build the current version it would cost around $170.00 to build plus add the cost of your preferred thermostat. This costing is an off the top of the head guess on the indiviual materials at the quantitys that you would need to buy. Plus on top of that is your time.

Regards
Trev

Hi Trev
Your incubator does not need any down time & you dont need a hatcher if you change a few things.
First: The frame you built to hold your egg tray does not need to be that high. By having it smaller you could move the thing a bit heigher & will give you more room below.
Next: Insted of using that big basket for hatching, make a timber frame with small wire mesh on the bottom, it doesnt have to be high.
This way you could have eggs in the tray incubating & at the same time eggs down the bottom hatching. I will post a picture of mine tomorrow with a few eggs in the hatch tray to show you what i mean.
Regards
Mario

Hi Mario,
Yes please to the pics - we are thinking along those lines so would appreciate seeing what you have done.
I have the incubation bug badly now - took the last eggs out tonight (candled and not good) and have the next lot ready to set tomorrow.

Hi Carmen
Another tip.
You dont need to keep moving your water container to change humidity.
Get a large plastic container with lid for the water, depth is not important, deep or shallow will not change humidity but surface area will. cut the lid into 4 pieces long ways. Once you put it in, if the humidity is to high, just place 1 piece of the lid on & the humidity will start going down & so on.
I use a thin piece of metal over my water tray & slide it where I need to get the right humidity.
Another thing: You will notice that your temperature & humidity will drop a lot lower when you open the top of your incubator opposed to opening the front. That is why there is an orange cup with a plastic hose going from the cup to the water container. This way I can add water with out opening the top.
I will bring my post to the top so you could see what I mean.
Any questions, feel free to ask
Regards
Mario

Great idea about the lid, thanks.
We only used a small tupperware in the bottom for the first part of the hatch - about 1" x 2" Then moved a chinese takeaway container (high tech state of the art equiptment :D ) under the lights for the last 3 days.
The humidity didnt drop hugely when refilling the water as we did it quick but will certainly explore using a larger container in the bottom to see how it goes.
Thanks for bumping up your thread, will have another look now.
Carmen.

You only need the container in the top. Keep the bottom for hatching

Will have to put a window in the top now :D
I actually had trouble keeping the humidity low enough without the water container running dry real fast with it up the top, which is why it was moved to the bottom.

With a large container, the water will last for about 3 days. I just look through the air hole in the side. After a few days you will work out how much water it uses daily. The cup also sits in a position that the middle of the cup is about 10mm below the top of the container. So after adding water, when the cup stays half full I know the container is full.
Regards
Mario

Another way is to use another hose. The hose to fill it is at the bottom of the container. You could put another hose at the top, going out of your incubator into a small container. When water starts coming out you know its full + it will never over flow into your incubator.
Regards
Mario

That was my worry with the hose - at the moment I cant see in the top.
Might have to drill a couple of extra holes while Trev is at work tomorow :D
