Individual Assignment
Develop a plan for dissemination of your final project.
Prepare drafts of your summary slide (presentation.png, 1920x1080) and video clip (presentation.mp4, 1080p HTML5, < ~minute, < ~10 MB) and put them in your website’s root directory
Develop a plan for dissemination
Vermicomposting system with sensors
The Continuous Flow Through Vermicomposting system can be split in two parts. The actual Continuous Flow Through box and the sensors.
The Continuous Flow Through box
The CFT box will be a CNC milled box with finger joints. There will also be 3d printed support brackets to hold the weight of the compost. To make the CFT box I will use Fusion 360 to sketch out the box. I may use Inkscape as well to finalize the design. Toolpaths for milling will be created in either Fusion or VCarve. The box will then be milled on the Shopbot CNC machine.
The support brackets will be made in either Tinkercad, Blender or both. I like using Tinkercad to block things out because I can easily use simple shapes and combine them together to make what I need. I´v not been using Blender a whole lot but I may use Blender for details modeling such as bevels and such. Once the 3d support bracket models are ready I will 3d print them in a Prusa i3 MK3S 3d printer.
This is just the first spiral for this project. In the future I would like to make the CFT box out of metal and plastic. A metal frame with plastic sides will make the whole system a lot more durable.
I would also like to work more on the electronics. I would like to add more sensors such as a humidity sensor to put in the compost. I would also like to add responses to the sensors, meaning, if the temperature drops below or over a certain threshold a heating/cooling response would help keep the compost at optimal temperature/humidity. I would also like to get the data online so I can monitor the compost from anywhere.
The sensors
The second part of the project is to make the sensors for the system. I will be using a DHT22 (temperature/humidity), a DS18B20 (temperature) and a MQ2 (gas) sensors. First thing will be to make all sensors work on a breadbord or wires. I will use I2C for communication between the controller and sensor nodes. The controller node will be a XIAO Esp32C3. The data will be displayed on a SSD1306 OLED display. The controller and nodes will be integrated in a 3d printed casing and mounted on the box.
Prepare drafts
I made simple drafts for both the slide and video.
