This device should absolutely never be allowed to run unattended for any length of time.
@LexYeen that's... actually a pretty good idea.
@starkatt Even if it's somethin' ripped out of an old toaster oven, yeah. Always best to err on the side of caution when it comes to mains voltage and heating elements, in my opinion.
@starkatt I suggest putting an analog power timer on its input somewhere, Just To Be Safe.
