Coffee Roaster
As with most of my projects, the idea for this one first came from my typical day-to-day activities. Specifically, after I had drank about my hundredth cup of coffee with my coworker in our office.
To begin my homemade coffee roaster, I just started spit-balling ideas with my coworker. Before I knew it, I had an entire design started up in my head. My first idea incorporated an entirely electric design. After a few trials that took about 3 times too long to roast, which resulted in tremendous loss in flavor, I decided to scrap the homemade electric heating coil design and go with a standard propane design like you might find documented all over the internet (sometimes the tried and true is the way to go).
There is still a long ways to go with the final design with adding automation to the design, but most all of mechanical operation has been completed.
