Nice, thought I'd share mine too. Mine is made out of scrap wood (left over ac3 treated decking, and a small bundle of lathe strips), a halogen lamp for heat, a side of a desktop PC to block the light and contains heat, screen door screen for shelves and a spare tarp that I used to cover the whole thing, including the roof with 3 layers
couple screen door latches on there, to keep it closed.. also have some of those sticky foam strips around the door to keep an air tight(ish) seal..
strips of wood on both sides to make shelves, the shelves themselfs are also made out of those strips of lathe, with screen stapled to them..
Here i show off the heating source, the 150 watt halogen lamp, with glass cover removed so it releases all the heat and doesn't keep it behind the glass, etc.. You can see the side of the PC I used, I use to use it as a wind block for my kettle, now repurposed to retain heat in lower section, so fan can slowly draw it upwards and out the top.
Here is the tiny fan, paid $5 at Wallgreens (50% off end of season sale) just last week.. Suppose to be a "high velocity" fan, but its hardly high velocity, I've had handheld foam blade fans that blow harder. lol.
Edit: I haven't used it for a full batch (all shelves), no more than 1 self at a time right now, since I've been harvesting as cones ripen. 1 shelf however can fully dry in about 8 hours in low humidity.
Also. in front of the fan and that dark spot in front of the light (on the floor) are openings covered in black animal proof screen (just had some laying around).. to let dry air in bottom and humid air out the top..
