Teenagers’ Engineering Initiative · Vancouver
TEI shares engineering projects, build records and design files so students can study the process and contribute their own work.
Founded by Eason Yang. I started TEI to make the thinking and practical details behind my projects useful to other students, and give them a place to share theirs.
Founder’s Work / featured · Eason Yang
Three sensing modes, one controller and a shared display. A working educational prototype combining ECG, EMG and optical sensing.
Built in 2025 · Electronics integration, software adaptation & enclosure design

Why I started TEI
I started TEI to share my engineering projects and make room for other students to share theirs. Each project should explain the problem, the person’s own contribution and what the evidence shows.
Eason Yang · Founder & project lead
I developed the biosignal prototype and designed and tested the two mechanical projects presented here. For TEI, I organize the project records and the submission process, with contributor credit kept separate from my own work.
Current progress
A working biosignal prototype and two tested mechanical projects form the published collection. The updates here describe the website; project pages carry the separate build and concept dates.
Community activity record →Added Behind the Project and updated both mechanical projects to reflect Eason’s completed testing.
Added the soldering jig’s ECG origin, clarified the homepage and founder’s role, and expanded the submission guide.
Recorded January 2026 concept dates, added the snowboard-maintenance motivation and consolidated validation plans.
Community Contributions
The published collection currently starts with Eason’s three projects. There are no external contributions published yet. Student concepts, CAD studies and prototypes are welcome for private review.
Share a project ↗A problem, your contribution and the current stage of your work. Add photos, files or a demonstration if you have them.
Each published contribution will carry its own author credit, dates and project status. Public text and files are agreed with the author before publication.
