Is it even possible....

my cooler is usually between 58 and 60 degrees and 70 to 72 RH. It's in my basement. I use it for storage and my humi is upstairs and is usually around 68 degrees and 60 RH.

I presume you don't have a basement.

Same thing I do. The basement is the best temp controlled area in the house.



On a side note, you can buy 110V/12V peltier based coolers for less than $100. Sometimes about $50 on sale. Not sure about thermostat capabilitites. Solar cells of sufficient capacity are even more than I originally thought. They cost about $20-$30 bucks per watt they provide at 12V.

I actually do have a basement, I guess I'll just have to put a thermometer down there, because I'm a horrible judge of temperature.

But thanks for all the advice on the powered cooling devices! I was thinking of incorporating something using heat sinks from a CPU, but couldn't envision how it could work.

The humi's been down there a while, and the humidity has stayed at my desired percentage. I will find out temperature this weekend and see. It's fine now, as seeing the mid-50's is rare here these days outside in the middle of the day, but summer is coming. Just wanted to be prepared. Plus, projects are always fun.
