need programmed control of heater #21

we need a way to enable and disable the heating element programmatically. i'm not sure how i've overlooked this, heh. i think a power MOSFET is the way to go, as a relay will both make noise and die after far fewer state changes. a triac would be even better, as i believe that would allow us to control the voltage. it would be better to run the heater continuously at a lower voltage than turn it off and on a bunch, if that is possible. but at a bare minimum, we need the ability to turn off the heater once the hotbox reaches the target temperature.

if we use a relay, we can probably put it in a loft above the perfboard. if we use a power transistor, we can probably just put that in the perfboard. either way, we'll need run AC over and up, and should put a wire channel on the floor along the wall.
