Project AI-23: Smart home retrofit utility sensor
This team will not have a booth at the Design & Innovation Day due to confidentiality agreements.
Project Client: CabinPals
Project Description: An easy, low-cost way for consumers to automate the tracking of home utility usage. The product, which is battery operated, can be attached to existing electrical, water, and gas meters without professional installation. The system uses a camera to capture the utility meter display and reads the digits using an optical character recognition (OCR) algorithm.
Project CG-49: Cost-Effective Control System and GUI for Portable All-in-one Automated Microfluidics
Project Client: UBC SoC Lab and BioMEMS Lab
Project Description: By providing a cost-effective pressure regulation device and a user-friendly GUI for use in microfluidics research and development, researchers and engineers can accelerate their innovations.

Project CG-65: Cost-Effective Automated Testing System based on Modified 3D Printer for Optimizing Assistive Switch Designs
Project Client: Neil Squire
Project Description: Neil Squire is a non-profit that uses technology, knowledge, and passion to empower Canadians with disabilities. Many assistive technology tools are still costly. The Makers Making Change program hosts an open-source library of assistive technology designs and collaborates with volunteer developers to give more people with disabilities access to the tools they need. Our project is to create an affordable, accurate and open-source testing system that will help Neil Squire’s staff and developers to characterize and optimize existing and new designs of assistive switches to provide the best experience for end-users.
The technical objective of the testing system is to accurately measure the actuation force and actuation distance at given points on the button. The user only needs to interact with our software, while the rest of the testing is automatic.
The major components of this project include:
- a 3D-printer, used to maneuver in 3D-space with precision and read coordinates
- a load cell (force sensor), used to measure the applied force at a given time
- a customized PCB, used to detect button activation and amplify signals
- an ESP32 microcontroller, used to communicate between software and hardware
- a GUI, used to communicate between software and hardware, as well as to process, format, and display data
