CAIBI project benchmark: Bela Pepper
Prompt version 1.0

Help me build Bela Pepper using the existing creator project at https://github.com/BelaPlatform/bela-pepper. This is a CAIBI benchmark adaptation of the project build brief, not a claim about how the creator used AI.

Project context:
- A Bela-based programmable Eurorack module with pots, buttons, LEDs and audio/control connections.
- Build context: Revision-matched PCB, faceplates and eight 100k potentiometers; Jacks, buttons, LEDs, passives, headers and regulator from the revision BOM; Compatible Bela/BeagleBone stack; the full DIY kit listing includes a Bela Starter Kit; Suitable modular case/power and patch connections as specified by the build route.
- Fabrication scope: Use the creator PCB and faceplate design for the exact revision. The current guide covers rev2 full kits after April 2022. Some photos show earlier resistor values; the current text and revision BOM take precedence.
- AI role: AI can explain Pure Data or code patches and help organise BOM checks. Solder quality, polarity, connector alignment and audio/CV limits remain builder responsibilities.
- Known limitation: Previous-generation Bela compatibility is documented; Bela Gem compatibility has not been established here. No physical validation or complete delivered cost.

Read the source first. Use its published design, files, dimensions and parts as the baseline; do not redesign it unless a missing detail requires a clearly labelled proposal. If you cannot access a source or verify a revision, say so.

Provide one practical build package:
1. Design and files: explain the source design, link the original editable files, and identify missing files or modifications.
2. Parts and fabrication: give quantities, exact variants and compatibility, plus a cutting or printing list where applicable. Preserve source dimensions; flag anything unconfirmed.
3. UK and US purchasing: direct product links, checked dates, stock, pack sizes, taxes, delivery and regional costs. Mark unverifiable details as unknown; do not invent links, prices or availability.
4. Assembly: an ordered guide covering fabrication, fitting, wiring or software as applicable, setup, checks and troubleshooting.
5. Cost and time: separate parts, fabrication, delivery, hands-on time and machine time, with assumptions and exclusions.
6. Function and ease: a test plan for the project's stated purpose, likely difficulties, required skills and any corrections or limitations.

Keep source facts, your proposals and items needing physical verification distinct. An estimate is not a measured build result. Do not claim to have built or tested hardware. Include failed attempts and omissions. If a section does not apply, say why.

Use the source as accessed during this run and record its revision or access date. The prompt is fixed; the linked source can change.
