I have been toying with the DIY bator for a while now. I was going to use a ceramic heat element that resembles these new florescent low energy bulbs for my heat source. (they are used to heat reptile enclosures) Instead of using a light bulb. I got to looking at the heater coils in a sportsman with the ceramic hangers and thought "hey I have a space heater with coils just like that in it!" I think for my dorm fridge bator, I am going to try this thing. It has a fan that sits right behind the coils. The only problem is when the Thermostat kicks the coils "off" the fan will go out as well. I have to find a way to wire the fan to stay on constantly. Wiring straight to the outlet tripped my breaker in the garage so that will not work! I can add a computer fan in its place running off a small transformer plug like I did in my foam one when it went out. I am just not sure if it will move enough air in such a vertical space. I am putting the glass in the door and will try it out tomorrow night. I have to make sure it does not get too hot. If i read correctly, The hot water heater thermostat (or wafer if that does not hold tight) should go inline in the power cord leading to the coils and break the circuit when it reaches the set temp thus regulating the heat by kicking the coils on and off. Let me know what you think or if you have any ideas on fans. I need to take pics before I get ahead of myself in case this thing works great. Those little heaters are dirt cheap!
