Fridge Incubator

This article needs more detail and I agree it does not look safe.

An update on how the incubator worked and more build details would help.

Did you find a better heat source?

Some good description of build but the safety aspects is worrisome.

Doesn't looks very safe.

Using a hair dryer as a heater/fan seems really unsafe. Doesn't it overheat and shut itself off?
