[DIYbio] Re: Building an incubator, would like some opinions/help

That actually would mean 1.5 kilowatts . That's a lot. That would easily burn the bugs. Our central heating unit has some 15 kW, but it heats the whole house, and a room-heat-radiator usually has some 1 kW.

It depends, of course, on how big the incubator is and how well-insulated. But actually, if good insulated, *some* watts will be enough, although pre-heating will be needed. I assume 144 Watts to be enough (if not much too much) anyways.
To heat one cubic meter air 15°C (Room temperature -> 35°C) you need (cp*mass*dT=1,005*1,2*15) 18 Joule which equals 18 Watt-seconds. That means, if it had 18 Watt it could heat 1m^3 per second. And as the incubator is insulated, you don't need to heat one cube meter per second, just compensate for the loss.



What you ment was also my approach, with the styrofoam incubator, some power resistors (and maybe a yet to be installed fan from a deceased computer). It's standing in my garage still...

So I am thinking of using a glass jar with sterile water and a sonic fogger to add RH.

Adding heat and stirring the air will be accomplished by a 12V 12A hair dryer...

Nathan,

are you sure that's 12 amps at 12 volts?  That would be only 144 watts.  That seems somewhat wimpy for a hair dryer.  Are you sure that's not 120 volts?   Most hair dryers use about 750 watts to 1500 watts.  For an incubator, why not use some power resistors and a fan?
