Session log — Interactive studio wiring diagram HTML

7 June 2026, morning · General · Hasmukh with Claude · auto-published from the local journal entry. A polished narrative version can be requested in any future Claude session.

Summary

Although it ran in the PageMotor 0.9.3b folder, this session had nothing to do with PageMotor: across 6 and 7 June it built interactive HTML maps of the broadcast studio wiring (ATEM switcher, Mac Studio, SDI/HDMI converters, Yamaha DM3 audio and more). A first map traced from a screenshot of the wire diagram was abandoned the same morning in favour of a pipeline where an editable spreadsheet is the source of truth and the HTML map is regenerated from it. When the Numbers app's Excel export proved unreadable, the updated rig was supplied as a PDF and the dataset rebuilt from it (40 devices, 47 cables, 8 connections still to verify). On 7 June, after Hasmukh pointed to the Vodacom FY2027 progress report as the navigation model, the map was rebuilt as a light, searchable single-page wiring report, and a bug where the floating column header covered table rows was fixed. Catch-up note reconstructed on 12 June 2026 from the saved conversation.

Decisions

Tracing wires from the screenshot was accepted only as best effort, with unconfirmed wires shown dashed and clearly flagged; Hasmukh then aborted that approach ("I will have to figure another approach").
The spreadsheet became the editable source of truth, with the interactive HTML generated from it (edit the sheet, regenerate the map).
Workbook structure settled as a hybrid: Devices and Connections tabs drive the generator (with a Verify flag per cable), plus readable Chain View, Cable Types and Summary tabs.
With Numbers' Excel export broken, a PDF export was adopted as the input format and its text extracted instead.
The presentation switched from the dark pan-and-zoom graph to the light report idiom of the Vodacom progress report (stat cards, search, filter, sort, expandable rows, clickable device pills), with charts drawn in CSS so the file works fully offline; the older graph map was kept as a secondary spatial view.
Connections Hasmukh could not confirm (room mic, talent IEM chain and others) stayed flagged as unverified rather than being presented as fact.

Changes made

Created studio-wiring-interactive.html in the 44 CLAUDE folder, the first map traced from the screenshot (43 devices, 48 cables), updated after two confirmation rounds to 14 confirmed and 34 inferred wires, and left in place after the approach was abandoned.
Created "SDI Setup - Interactive.html" in Documents, an accurate map built from Hasmukh's own "SDI Setup detail.xlsx" (24 devices, 28 cables) with end-to-end signal-path tracing.
Created "SDI Setup - Full Input.xlsx" in Documents, the five-tab editable workbook covering the whole studio; first populated with 47 devices and 56 connections, later rebuilt from the PDF to 40 devices and 47 cables with 8 flagged to verify.
Created "SDI Setup - Full Map.html" in Documents, the interactive graph map generated from the workbook and regenerated after the PDF update, which brought in the new gear (BM Pyxis 6K camera, Yamaha DM3 mixer, CISCO 24-port switch, Broadcast and ZoomISO Mac Minis, U-TAP capture, Decimator).
Created "SDI Setup - Wiring Report.html" in Documents on 7 June, the new primary view in the report style, then fixed its sticky header so it no longer hides the first table rows.
Cleaned up all temporary preview copies and scaffolding; Hasmukh's original spreadsheet and PDF were left untouched.

Follow-ups

Work through the 8 flagged connections in the workbook (Broadcast Mac Mini converter number, the unassigned HDMI2SDI 05 source, the two MultiView re-entry loops, the Decimator signal type, the SDI2HDMI 05 destination, the Mac Studio front versus back USB-C port feeding the OWC hub, and the USB-A run into CISCO port 20), then regenerate so dashed lines turn solid.
Open offer to model the CISCO switch as a Dante pass-through so audio paths trace end to end (mixer to switch to AVIO to headphone amp to IEM).
Optional refinements offered on the wiring report: grouping by location, a printable mode, and a default sort by signal-flow order.
Hasmukh had not yet fully examined the new wiring report when the session ended.
