-base from slow cooker/crock pot (found at dump)
-110V fan (though a 12V should work as well but then you'd need a power supply as well)
-thermostat assembly from an electric stove (found at dump) (save all the screws you take out to get the back of the stove and use them to mount the shelves etc.)
-neon indicator lights from same stove
-racks/shelves from old stove/fridge
-piece of aluminum angle cut into +/- 1" pieces for rack hangers
-on/off switch (a regular house light switch would work as well, but not as cool..)
-misc. wire, crimp terminals and wire nuts and misc. fasteners
-Mylar sheet/aluminum foil
-aluminum tape, duct tape
-screen material to cover vents and lay on racks
-And of course, some fruit to dry
-drill, bits, holesaw
-And most important, basic common sense and the humility to ask for advice when needed.
