Especially the acrylic door is intriguing! If i ever built an incubator it will have a glass or acrylic door for sure. The article is well written, but there are not enough details, like a basic wiring diagram and the pictures are too tiny to see any details.
The incubator itself looks great! An amazing hatch rate for sure.
A better break down of supplies and exactly how it was assembled would be useful, as I wouldn't mind building one like this myself.
