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)
- W3005 Digital Display Microcomputer Humidity Controller 12V (x2) (13.68)
- Portable Mini Humidifier (3.
66)71) - Small Thermoelectric cooler kit (5.89)
- Thermoelectric Cooler 12706 (3.35)
- Power Supply 12V 5A (7.90)
- DC-DC Buck Converter Single Square USB (3.60)
This makes the total cost 34.48$42.75$ (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.
