I think this article is well written and the photos are really helpful. I learned a lot and it makes me feel like I could make this frankenbator. I'd rather not though, because it also makes me thankful for my incuview.
It did. I have only really used them as lock down incubators, because I currently live in a house that isn't climate controlled. The incubator has a hard time with wide temperature shifts. I'll have to see if moving to a house with HVAC in the next few months will change that.
