I am building an incubator for elementary kids to hatch chicken eggs. Part
of the challenge is to use only free, recovered items So far all items have
been free:
- Omaha Steaks shipping box
- plexiglass from discarded poster frame
- electric cord with plug
- light socket- computer cooling fan with wall wart (for circulation)
- wire mesh.

Only items I'm missing are thermostat and thermometer. I know that many
household appliances contain temperature regulation devices such as
thermostats, thermal switches and thermistors. Some appliances and systems
even have temp control circuits with digital readout.

My challenge is to find something that will hold temp at about 100°F (38°C)
and run on 120Vac. Clothes dryer? Oven? Iron? TV?

As long as I can find a really heavy-duty heater, this might be the best
solution. Most small aquarium heaters are rated pretty low, so a light bulb
might be too much current.I'll post for one on Freecycle and see what
happens.

Wterbed heater or just it's controller, if you use the heat mat bed it
in sand

I thought about that one and called the waterbed and spa store. They seemed
to think the temp range would be much lower than 100°. I'll see if I can
find one and alter it.

Jeeze! Use a hen.

After the eggs hatch:

Use a 75-watt light bulb. Check the chicks. If they move closer to the bulb,
increase the wattage.

You don't need no stinkin' "thermostat."

i fix laminating machines for a living and will send you a thermostat
and heater, have lots of used ones.

my concern is they top out at 400 degrees. care must be used to prevent
a bad day.

e mail me if your interested hallerb americaonline
