Hi Corey,
Thats great! This is
exactly what we need! I'll be in touch , I'll have a look on it and
we are going to discuss it on our next meeting on Tuesday around 9
pm! I'll propose to get founding for it from our budget. Do you think
that we have a really chance to get the proper fridge within two
months or so?

Once more thanks,

See you,

Frantisek

 Who likes cheese?  Who likes Salami?  Who likes otherwise moldy or bacteria rich food?  Who wants to make some moldy food of their own?

I
already do this.  I make salami (That's right, it's fermented/raw pork)
and I have no intention of making it at noisebridge, but there is a bio
group forming and I have a simple way to encapsulate your moldy food
growing experiment so people don't have to experience your festering
salami second hand.

Incubator
How to make the perfect environment for growing cultures...at least for cheese and salami.

Control unit
This is the correct unit, but it needs to be ordered as a "Cooling Thermostat,
Humidistat" instead of a "Cooling Thermostat, Dehumidistat."  I imagine
they just rewire a relay, then ship it, because my unit arrived with
all the "Dehumidistat" documentation.
https://www.greenair.com/browse/ct-dh-series.html

This
is the expensive part, about $80.  This is where geeks could get
together and make something better.  I am sure an arduino with a couple
relays and a couple sensors could do this task just fine.

Other components

	* Cool Humidifier (as opposed to hot humidifier)
	* 5w-10w lightbulb
	* Modern Fridge (the kind that dehumidify/deice...you know, anything from the past 30 years.)

Basically, the power setup is as such:

	* Power strip
	* Light (installed in fridge)
	* Humidistat/Thermostat
	* Fridge connected to thermostat port

	* Humidifier connected to HumidistatThe
hardest part to find is the cooling humidifier.  Some use paper
membranes or foam or other porous materials.  These are no good.  The
best, and I've only come across one and I guard it with my life, is a
combination of a centrifugal pump and a squirrel cage fan, all in one.
(In fact, the delay on my e-mail was I wanted to pull up the info and
see if I could find it on sale online.)  The reason this is important
is because the porous material quickly becomes inundated with mold.

So what does this do?

	1. The lamp, being always on, heats the enclosure.
	2. The
fridge turns on when the heat exceeds the desired amount (according to
the thermostat on the control unit since, while curing, we want the
temperature around 70 degrees, well above the range of fridge
thermostats.)  In the process of cooling, the enclosure is also
dehumidified
	3. When the enclosure turns too dry, the humidistat clicks on and powers the humidifier.We
have everything to heat, cool, dry, and humidify the enclosure.  Apart
from the controller, everything is cheap and readily available.  I have
some ideas on replacing the humidifier but that is up for further
discussion.

One obvious modification to this is the lamp.  Does it always need
to be on?  No, but having a candelabra light on for a year is still
cheaper than getting a dedicated thermostat...unless we roll our own.

Your Mileage May Vary, This message comes with no warranty, I am not responsible for you getting food poisoning, "It Works Right On My System(tm)", the wrong bacteria will fucking kill you, share and enjoy!
