Interactive Recycling Bins
12th Grade Science | Brooklyn International High School
Role:
Project Designer — partnered with a 12th grade science teacher to prototype the project, develop instructional materials, and scaffold fabrication and programming processes for student use.
Project Description:
As part of an ecology unit and their graduation portfolio, students built interactive recycling stations that required practicing woodworking, circuitry, and programming skills. Each bin had three receptacles (trash, paper, plastics/metal) with proximity sensors connected to a Raspberry Pi. When items were deposited, the bins triggered student-designed infographics and animations on a TFT screen.
Design Approach:
I created a prototype recycling station that demonstrated the integration of fabrication, circuitry, and programming. I created instructional materials, including cut lists and circuitry diagrams, and led skill and tool demonstrations for each class. To support students, I developed a Processing-based template system that allowed them to import and sequence their own GIFs and animations without needing to code entirely from scratch. I also preconfigured each Raspberry Pi with startup scripts so projects would boot directly into the student programs. This design approach emphasized accessibility, creativity, and exposure to a wide variety of making practices.
Project Sequence:
Students built wooden frames in the school’s fab lab, which involved cutting, sanding, staining, and assembling with screws.
They laser-cut plywood lids with disposal holes and a screen mount, then decorated the lids to make the bins visually engaging.
They assembled Raspberry Pi circuits with three proximity sensors and a TFT screen, practicing soldering and following circuit diagrams.
Using a Processing template, students created custom infographics and animations that displayed based on the type of trash disposed.
Twelve unique recycling stations were completed across multiple class sections and installed throughout the school for community use.
Student Learning Outcomes:
Practiced woodworking and digital fabrication (measuring, cutting, staining, laser cutting, vinyl cutting).
Developed basic electronics and soldering skills through Raspberry Pi circuits and sensors.
Gained exposure to programming concepts in Processing while creating custom animations and infographics.
Built collaboration and project management skills through a long-term, multi-class build.
Contributed to the school community by producing functional recycling stations installed campus-wide.
