It was a fresh and exciting way to start our semester. As we move on to complete all the homework we have put off, we'd like to give a big thanks to our friends, senpais, Build18 officers and all the sponsors. We couldn't have done it without you!

Demo day was FUN! In the end deJunk could only separate trash into two categories due to difficulties controlling voltage output from the rpi. The change in voltage was what decided which way our sorter plate would tilt, but we only managed to have the rpi output two voltages, meaning our plate could only fix itself at two positions (upright or tilting). We therefore decided to do recyclables and landfill only, as opposed to our initial plan that considered compostables. Although the project did not come out as intended, it gave us valuable experience with mechatronics.

Got img recognition working. Kudos to Halanna Yuh! Now working on controlling the arduino via rpi.

Building in progress! Assembled majority of trash bin. Trying to debug our image recognition program and our pan tilt kit.
