Has anyone here ever made their own solar oven? I’ve cooked with a small portable one while camping but Id love to build my own backyard model I could make a few meals with at a time.

Most of the DIY solar oven projects Ive see out there are made out of cardboard and materials unlikely to last long. Id really like mine to last and be durable. You can buy nice ones I know, but Id really like to construct my own if possible.

Just looking for tips, thoughts, or resources you folks might have seen. Any suggestions on building it, using it, etc. are welcome!
