I'm lookin into making a homemade incubator but I'm confused I understand that you need a heat source (light), a fan, a thermostat and a thermometer. The problem is that my dad (who is helping me make it) says all the computer fans we have run off of DC current and he does t think we could use it and he doesn't know how to wire it. So can we use it? If so how? Thanks y'all!
