Program narrative
Build firmware-facing benches: UART scripted ordeals, GPIO fault buses, and ADC stimulus paths. You will script pytest front-ends to UART bridges, design safe fault insertion, and capture evidence packets mentors can review asynchronously.
What ships in the syllabus
- Harness architecture sketch templates
- Fault bus soldering clinic with safety interlocks
- Pytest + serial bridge lab with timeouts that teach
- Measurement uncertainty primer for ADC tests
- Nightly job layout without cloud dependency
- Artifact naming conventions for long-running teams
- Mentor async review of your harness README
Outcomes we can observe
- Assemble a bench that reproduces three seeded faults
- Automate a smoke suite with deterministic teardown
- Write a measurement note explaining guard bands

Cohort murmurs
Quote-first
Fault bus week was loud but precise — our nightly job finally fails loudly instead of silently.

Still tightening pytest timeouts, but the measurement note template is already in our drive.
