The Enclosure is made out of 1/4" thick plywood, 1x4 studs and contains foam insulation on the inside held together by wood glue and nails. They overlap one another to prevent air leakage and to be able to hold as much smoke as possible. An acrylic sheet is used to visually track the movement of the smoke that comes from out of the fog machine. Along the side, three cans are stacked on top of each other and have holes punctured in them so they can be heated in order to produce the solar chimney effect.
The electronic controls included an Elegoo Uno R3 board with a breadboard that is attached to a 16x2 LCD display and a DHT22 to measure temperature and humidity. A code was provided in order to display the temperature in Fahrenheit and humidity that would constantly update and provide temperature and humidity in real time.
Controls (electronics update)
A second DHT22 temperature sensor was added to the breadboard in order to compare the temperature outside the enclosure versus the changes created within the inside of the enclosure. In order to have the two DHT22 sensors to be working, changes to the code were made in order for the LCD screen to display both temperatures.
Parts & Pieces
A hole measuring 1 1/2" was added to the back of the enclosure in order to better accommodate the fog machine. Also two 3D printed 1/2" pvc hose "adapter" pieces were created to create a better link with the fog machine and enclosure leaving little room for extra leaks of fog when filling up the box.
