Okay this is my first attempt at a homemade incubator. I used parts that I salvaged out of my old microwave - please note (as Denis mentioned) that microwaves can kill so be VERY careful if you decide to remove parts from it. It's an auto-turn and works okay so far - I'm not sure how the eggs will fare with the rolling about (it's pretty random) - may need to tweak a bit more. This model is still air - only because I didn't have a spare cpu fan available. I was going to use the microwave fan (I still saved it because it's 240V unlike the computer fans which are 12V) but that baby blows a phenomenal amount of air and I didn't think I needed all that airflow - plus it's huge and I didn't think it'll fit in the existing incubator (which is a styrofoam box - a bit small but then this is a trial run - eggs are pekin bantams so they are smaller than the usual standard hens). The electric digital timer that I bought from Bunnings lasted 2 days (I'm not impressed) - during that time, the whole set up was fully automatic - turns the eggs 3 times a day on the timer for a minute each time.

Fingers crossed I'll hatch some :D

Hi,

Are the eggs turning like that all the time? Did you wire the turner into the same circuit as the light (i.e. can it be put onto a separate cord?)?

Reason I ask is that it looks real fast... and I've been thinking about how I would do my own one (without Denis' knowledge about electronics :roll: ) and have decided that I will buy a small digital timer that I can plug my turner into so that it turns for 1 minute, 20 times a day. These are pretty easy to come by (I think you can even get them at Coles) . I have a Brower bator here atm that uses exactly the same action as you have made but it turns very very slowly... you don't want to scramble you eggs ;)

My Canon Digital Camera records movies - just have to keep it short otherwise it takes up a lot of space.

The microwave motor is pretty slow but still it does look like the eggs are taking a bit of a beating - I guess it's a trial and error thing - I contemplated creating a conveyor belt (similar to what the Roll X does but actually sitting the eggs on a belt, not on the rollers) with fixed bars across widthwise to keep the eggs in place and then have the conveyor belt move underneath them. But I thought I'd try this first and see how I go. The thing I did notice about the microwave motor is that it rotates in alternate directions each time ie 1st clockwise then anti-clockwise, so not in the same direction each time. Again one of the quirks I guess that will need to be tested and tried and tossed out if it doesn't work.

I didn't wire it to the thermostat. I just plugged the motor onto a digital timer which was set to rotate 1 minute 3 times a day. I figured if people turn manually 3 times a day, then auto-turning them the same would be okay too. It's all trial and error. I tried to wire everything as is with the microwave as the casing but I think like the pie bator, it loses a lot of heat - so I opted for the styrofoam box - I think I'll get something bigger next time.

I'll let you know how it turns out. The fun's in the experimentation. :wink:
