I built my dehydrator using this video as a guide: How to make your own solar food dehydrator. I cobbled it together from some of the old boards lying around in the barn instead of using a table (which I don't recommend, but it worked). I'm definitely planning on making a better one later, but this still did the trick. For the food itself, I picked some apples and asian pears from the scraggly old grove on my mom's land.
Note: I did this in early September, I'm just bad at remembering to post lol

I dehydrated two pounds of red onions. I didn't have a "proper" solar dehydrator so I used my solar oven because I saw someone else had used the same oven for their BB. It seemed to keep the onions between 108 and 130 degrees (F), which is pretty good for dehydration (I checked the temperature regularly as I also had to keep rotating the oven with the sun). This is definitely making me want to build a large solar dehydrator for future projects.
It took two days to fully dehydrate all of the onions. I'm sure it would have gone faster if I had chopped them up smaller but I wasn't sure if the wind would blow all the bits away. Overnight I put the whole setup in the greenhouse and put the onions under a cloth. I only had one small piece that looked like it had gone bad (turned brown) and the rest all looked fine. After it was done I ground it all up in a blender and made onion powder.
