Just finished up my cave tonight. No cheese yet, because I needed this cave completed before ruining some experiments. I will be asking alot of questions as I dive into this unique world of cheese.
Picked up a smaller freezer off craigslist for 50 bucks
Had an old emergency light box laying around, so I cut some holes to make room for a PID controller to hold the freezer temp steady and to control humidity.
Here are the controllers slid in place to see if the units would fit.
Cut holes in the back of the box for some plug inserts. Checking size of holes.
Had to build a bracket for the thermocouple. Good ol aluminum.
Installed the thermocouple and humidity sensor
Mounted the box after wiring it up and powered it up. No smoke
Drilled a hole in the bottom/back area of the fridge to let fresh air in. A 1 1/2 PVC coupling fit perfect to line the hole
Covered the fresh air inlet with a piece of stainless mesh and some air conditioner filter material to keep dust and beasties out. I hear little critters like cheese.
Next cut in a fan to help dehumidify the cave if the humidity spikes. This will be controlled by the humidity PID along with the humidifier.
Last was the humidifier installed in the lower area of the cave.
