A cheap, easy heater for small chicken coops.

Step 1: Ingredients:

I used a $2 lunchbox from the local cheap junk /dollar store, and a HEMMA light from IKEA. I also purchased a Thermocube to regulate the temperature.

Step 2: Cutting the Hole

Make the hole the same size as the threaded portion of the HEMMA light base. I didn't have a regular hole saw small enough to make the circle. I briefly considered using metal snips, but decided to go with my "dial saw" to at least make the circle. It's really a wood cutting tool. Had I been a bit smarter, I would have clamped a bit of wood behind the metal, as it's very thin and easily deformed.

Step 3: First Aid

Trying to pull that last bit of the cut out piece of metal off the lunchbox turned out to be ill advised. After applying light pressure and letting my dog lick the blood off, I grabbed the metal snips and removed the hanging chad.

Step 4: Assembly

Now I pushed the threaded piece of the lamp through the hole, and screwed the provided flange over it. This sandwiches the metal between the 2 plastic flanges of the lamp. Next, one could insert the incandescent light bulb of choice, being sure that they touched no walls of the box. Since my wife has low wattage bulbs for her Scentsy business, I used an adapter and a 25 watt bulb. If it doesn't seem to be enough, I'll up size it.
