I'm going to do this in probably three parts it's very in-depth and I don't have time to show it all at once I hope everyone understands. It will seem complicated but that is just because I'm going step-by-step.
1. 8 bottle wine cooler.(any size will work).
2. Bi-Metal thermostat (Incubator Warehouse $22.00 incl.shipping)
3. Peltier cooler (amazon.com $10.38 incl.shipping) If you cooler works you won't need this part.
4. Heatsink paste (amazon.com about $10.00) You will need this no matter what.
5. Old lamp cord or equivalent.
6. Assorted tools screwdrivers,drill,wire strippers etc,etc,
7. something to connect wires together heatshrink or wirenuts or even electrical tape.
This is what I'm starting with:$25.00 from Wal-Mart several years ago.
First: Remove interior and back cover.
Drill hole where you want the control knob. I am using an old speaker wire box but, this is not necessary.
Second: cut hole on inside of cooler large enough to accommodate thermostat:... sorry so blurry it's a hard place to get a good picture.
Third: drill hole in back corner to pass thermostat wires through to the back... I am using an old lamp cord.
Fourth: Remove cooling unit from the back two screws(interior piece will also be removed at this point). Large Aluminum piece that looks like a Heatsink.
At this point we veer a bit depending on weather you are using a new cooler or the one that comes with it, if your cooler works you don't need to replace the Peltier cooler.
USING EXISTING PELTIER COOLER: Follow heat paste manufacturer instructions on cleaning and applying paste all you need to do is apply the new paste and flip the cooler so it's heating the inside instead of cooling it.
USING A NEW PELTIER COOLER: Remove the old heater, I used female plugs from the old one so snip and strip the old wires and splice with wire nuts,heat shrink tube,whatever you want. Plug back in,plug in cooler and find out which side of cooler is the hot side this side faces in(obviously).Reassemble the cooling unit.
This is a wiring diagram I drew up to help make it easier to understand,
