CAIBI project benchmark: OpenAstroExplorer v1.0
Prompt version 1.0

Help me build OpenAstroExplorer v1.0 using the existing creator project at https://github.com/OpenAstroTech/OpenAstroExplorer. This is a CAIBI benchmark adaptation of the project build brief, not a claim about how the creator used AI.

Project context:
- A compact open-source equatorial mount for light-to-midrange astrophotography, combining printed mechanics, belt and worm drives, stepper control and built-in automatic polar-alignment hardware.
- Build context: Printed OAE mechanical parts and heat-set inserts or the equivalent seller-prepared printed set; 2020/4040 aluminium extrusions and Arca-compatible clamps/plates; 6012, 625, F695, 6907, F6006, 51111 and LM5UU bearing set; GT2 pulleys and belts, 50T worm gear set and MGN9C linear rail; Custom OAE board, ESP32, two TMC2209 drivers and two A4988 drivers; RA 0.9-degree NEMA 17, dual-shaft DEC NEMA 17 and two small Alt/Az steppers; Fasteners, small parts and wiring; Sturdy EQ5-compatible or Arca-compatible tripod supplied separately; Counterweights supplied separately, roughly matched to the mounted gear weight; 12 V power supply rated at least 2 A supplied separately; Camera or telescope, imaging accessories and optional guider supplied separately.
- Where AI helps: Navigate the BOM, CAD, printed-parts list and assembly documentation, Separate the complete-kit, hardware-kit and fully self-sourced routes, Help check part specifications before ordering or printing, Explain firmware configuration and mount-control concepts, Help investigate ASCOM, INDI, PHD2 and guiding logs, Calculate planning values for balance, gearing and imaging scale, Help document modifications after the baseline mount works.
- Physical work: Choose a latitude, tripod and payload route that suits the actual observing setup, Print or buy the mechanical parts and inspect critical fits, Drill and tap raw extrusions where the selected sourcing route requires it, Install bearings, belts, pulleys, worm drive, linear rail and fasteners without introducing binding or play, Wire the controller, drivers and motors correctly with power disconnected, Provide a stable 12 V supply and safe outdoor power arrangement, Mount and balance the camera or telescope with suitable counterweights, Physically align, polar-align, calibrate and guide the real mount, Verify tracking, cable clearance and stability before leaving a session unattended.
- Main limitation: The €399 kit is not a complete astrophotography setup. You still need a rigid tripod, roughly matched counterweights, a suitable 12 V supply and the imaging equipment itself. Tracking quality depends on mechanical fit, balance, polar alignment, firmware configuration and real guiding performance. The published 0.6-0.9 arcsecond RMS figure is a source specification, not an independent CAIBI measurement.

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.
