Me either. With the cooler weather upon us I have returned to thinking
about building my thermostatically controlled proofing chamber, but more
on that another day.

Howdy,

If you need help with this, please post again. There are a number of
techniques that are easy, and inexpensive.

Easy and inexpensive sounds good to me! I have the following parts on
hand:

- A clear plastic storage bin for main enclosure
- 12 volt DC power supply ( AC wall adapter )
- standard round Honeywell mechanical home thermostat
- 12 volt computer fan for circulation
- 110 VAC lamp fixture for heating element

I think all I need now is an appropriate relay with 12 VDC coil which
should be available cheaply at RxxxxShack, and some sort of small
enclosure for the "guts".

I have already seen discussions in earlier threads about Samartha's fish
tank heater, Dick's modified coffee pot thermostat, and your own
modified refrigerator. Good solutions all! More ideas are certainly
welcome.

Hi Steve,

I think you are probably ahead of me...

I would forget about the fan, get the relay, screw in a low wattage
bulb, and turn it on and off with the thermostat. Put something above
the bulb so that the warm air coming off it will have to "go around
the barrier." With that, convection will even out the temperature
inside the box.

Have fun with it. I think you are on your way.

All the best,
