Behind the Project / Founder’s account
Why I started TEI, the work I contributed, the decisions behind the site and what I want to build next.
09 / TEI01 / Starting point
A finished photograph shows an outcome, but it leaves out the wiring, code, mechanical choices and debugging that made it possible. I wanted my projects to be useful to someone trying to understand that work.
I started TEI to share my own engineering projects and make room for other students to present theirs. The starting collection is my biosignal monitor, wire soldering jig and bench vice. The aim is to connect each project’s purpose with its author’s work and the evidence behind it.
As more students contribute, the collection can offer different approaches to everyday problems and examples that others can study, adapt and discuss.
02 / My contribution
I integrated the biosignal monitor’s electronics, adapted its MicroPython application, designed its enclosure and worked through debugging. I also designed and tested the wire soldering jig and bench vice. Existing modules, software references and libraries are credited on the project pages.
I bring together the project files, photographs and development notes, and define how the site presents the problem, contribution, results and next steps. CAD illustrations and physical photographs are labelled so readers can tell what each image shows.
I organize the submission and review process. Future contributors keep their own author credit; any editing or organizational contribution will be identified separately. Public text, files and credit are agreed before publication.

Biosignal Monitor / build record, August 2025
The development record describes an operating fault and observed heating. Replacing the STEPico controller restored operation and stopped the observed heating. The record does not establish the original fault’s cause.
This iteration sits alongside the build photographs and source files, so readers can see an issue, the change made and the observed result.

After completing the ECG project, I looked back on how awkward soldering had been. That experience led to the idea of a fixture to keep wire ends aligned and the joint accessible. I designed and tested the jig.

Thinking about maintaining my snowboard led me to explore a screw-driven vice. I wanted a stable way to hold the work while keeping my hands free. I designed and tested the vice.

The biosignal monitor leads because it brings together electronics, software and enclosure design, with photographs and a detailed build record. The two mechanical projects add examples of clamping, guided movement and assembly.
The project pages introduce the purpose and my contribution before the detailed files and instructions. This gives readers an overview while keeping the technical record available for a closer look.
Founder’s Work and Community Contributions have separate entry points. Projects carry an author and current status, so a growing collection can still show who designed, tested, wrote or edited each part.
05 / Current stage & next steps
The collection currently contains my working biosignal prototype and two tested mechanical projects. External contributions are not yet published, and the first workshop remains in planning.
