Engineering Process
A disciplined path from idea to production.
Every project on this site followed this workflow. It isn't a diagram from a textbook — it's the sequence I've personally executed, bench time included, across four products.
- 01
Requirements
Define what the product must do, its constraints, and its environment.
- 02
Architecture
Partition the system — power, control, sensing, communication, UI.
- 03
Schematic
Capture the design with components selected for performance and availability.
- 04
PCB Layout
Multi-layer layout and routing with DFM in mind from rev A.
- 05
Prototype
Fabricate, assemble, and rework boards on the bench.
- 06
Firmware
Embedded C on bare metal or RTOS — drivers, control, UI.
- 07
Bring-Up
First power-on, rail checks, clocks, programming interfaces.
- 08
Testing
Oscilloscope-based validation of signals, power, and behavior.
- 09
Validation
Iterate hardware and firmware until the design is reliable.
- 10
Production
DFM revisions, vendor coordination, and manufacturing support.
Proof
The process, applied.
Each case study documents how this workflow played out on real hardware — including the revisions it took to get there.
