A hoppie (not a hopi or hippie) is one who attends the Johns Hopkins Univ.
Get it?
Anyway, I am trying to find out the best way to cool a terrarium. I use
submersible aquarium heaters to heat them in winter, and I need an
analogous way to cool them in summer. My dad told me to look into
using a "thermo-electric module," which apparently works as a heater *or*
a cooler, depending on the direction of the current.
Does anyone know about these things? Anyone used them? Where can I get them?
