# BOM and Overview

For this project I am in the works of designing a humidity chamber for controlling the temperature of popcorn. My goals for this is for it to be under 50 dollars and to not look like a piece of crap.

#### Parts

- Sterilite 20 quart airtight container (could be any container)

This makes the total cost 42.75$ (excluding the container and other mounting hardware such as 3d prints). I will work on finding cheaper alternatives but as for the time being these are the cheapest parts. I hope to order these parts on 03/08/26.
