Project 1
Composting Monitoring System

Problem Statement
Composting is a great way to reduce unnecessary organic waste addition to landfills. This waste degrades inside of oxygen-deprived plastic bags, resulting in anaerobic digestion, which, in turn, results in the release of methane, nitrous oxides, carbon dioxide, and hydrogen sulfides--all greenhouse gases. However, without careful monitoring, compost done at home can also create these anaerobic byproducts. Not only are these gases inhibiting the recovery of our atmosphere, they also make the composting an unpleasant experience. This project will address these issues by taking the guess work out of composting; by developing a sensor array that will detect GHG, internal and surface temperatures, relative humidity, and soil moisture, the user will be able to more accurately determine when to aerate their compost, adjust to nitrogen saturation (which can lead to anaerobic digestion), and more, the compost can be made in a more efficient and reliable manner.

Project Plan
- Construct sensor array

- Create fan/sensor switch

- Finalize overall construction (door, crank, chamber/tubes)

- Test chain of events in bin usage (turning crank, fan timing, etc.)next project we were assigned to create a compost bin...

Week #1 Narrative
we discussed with team what we where we wanted to go with the project

i was assigned with the crank shaft

I started off by creating some sketches of potential crank shaft designs, factors i had to consider while making the shaft were

- the dimensions as i didnt know how big the bin would be yet

- build material

- number of vertical poles

- how many directions the poles should go

Week #2 Narrative
i made a few sketches of what i wan the shaft to look like and i started purchasing supplies
