FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Aviation & MRO Testing
Avionics LRU Bench Testing and Analytics
Learn how avionics LRU bench tests work, from induction to release, and how to turn CMM test results into analytics with TofuPilot.
- Aviation & MRO Testing
Reduce No-Fault-Found (NFF) in Testing
Learn what No-Fault-Found means, why units pass on the bench yet fail in service, and how to catch the pattern using your own test data in TofuPilot.
- Test Station Setup
Why & How to Run Test Stations Without Root
Running a test station as root is a costly shortcut. Learn least-privilege setup on Linux and Windows: low-privilege account, scoped hardware access, a service.
- Concepts & Methodology
TofuPilot Framework vs OpenHTF
How the TofuPilot Framework and OpenHTF differ, and how each one plugs into the TofuPilot dashboard and stations for live test data.
- Test Station Setup
Operator Interface with OpenHTF
Build an operator interface for OpenHTF tests: the built-in Station Server, user input plugs, and the richer UI available through the TofuPilot CLI.
- Migrating from Legacy Systems
Migrate a Station from v1.0 to TofuPilot CLI
Move a test bench from the v1.0 desktop station app to the TofuPilot CLI: one-command install, automatic deploys, and a live operator UI.
- Test Station Operations
Realtime and Deploys on Self-Hosted TofuPilot
Add the Centrifugo realtime server and the Docker-in-Docker deployer to a self-hosted TofuPilot instance for live status and Git-push deployments.
- Migrating from Legacy Systems
Migrate OpenHTF Scripts to TofuPilot CLI
Run existing OpenHTF scripts on the TofuPilot CLI with no rewrite, and decide which ones are worth porting to the TofuPilot Framework.
- Getting Started
Why TofuPilot Needs Administration: write
Learn why the TofuPilot GitHub App requests Administration: write, what it enables, and how to scope it safely with selected repositories.
- Quality & Process Control
What Is a Histogram in Manufacturing Test
A histogram shows the distribution shape of your measurement data. Learn how to read histogram patterns, spot problems, and use them for SPC in TofuPilot.
- Quality & Process Control
Cpk vs Ppk: What's the Difference
Cpk and Ppk both measure process capability, but use different standard deviations. Learn when to use each, what the gap reveals, and compare them in TofuPilot.
- Quality & Process Control
What Is Ppl and Ppu (One-Sided Performance)
Ppl and Ppu measure long-term process performance against individual spec limits. Learn the formulas, how they relate to Cpl/Cpu, and track them in TofuPilot.
