Brief Summary: Recyclid is a conceptual replacement lid to standard Rubbermaid trash bins that contains recycling and landfill divided sections. Each section contains a mock up display that is activated by sensors detecting trash thrown in each hole. These displays aim to provide a direct impact to users of how their recycling actions have a direct impact in the world, hence encouraging more recycling whenever possible.

Assembly + Electronics

We used PING ultrasonic sensors driven by a Feather Board. The two servos driving the displays were connected to an additional Arduino board due to power constraints.


The servos controlled the rotating display, using the very fundamental definition of a “motion picture”. Behind the display shown lies an LED, which is within the reflector made with aluminum foil. The purpose of this assembly is for the image in focus to be brought to attention.

Electronics Iteration

The main iterative component in the hardware was ensuring sensing repeatability, and modifying the power input layout to drive the servos.
