Funkelfetisch/projectMM: monthly activity digest

What landed on Funkelfetisch/projectMM, month by month. External-context reference, a factual log of a friend repo's activity, not projectMM's own history or roadmap. Newest month on top. The reusable prompt that generates these lives in README.md.

This is a fork of this project building a commercial product on it: HELIO, a physical "infinity sphere" lamp (a warm-white 3000 K RGBW strip inside a clear acrylic shell). The fork's own plan documents describe matching a browser preview to "the transmitted LED frame, warm-white output, clear acrylic, internal reflections, and optional wall bounce", and its firmware carries a helio1 sdkconfig variant, a curated preset player, and a branded update channel. The README is unchanged from ours, so this is projectMM plus a product layer rather than a rebrand.

Branch note: the work is not on the default branch. main tracks our upstream and has not moved since 2026-07-09; every change lives in named branches, so each month below carries a Branches line for what moved on them. The repository has no issues and publishes no releases.

August 2026

  • HELIO product layer, stabilised. One large commit ("Stabilize HELIO scenes, previews, output, and onboarding", 147 files vs our main) covering scene playback, the browser preview, LED output and first-run onboarding for the sphere product.
  • A browser-side optical simulation of the lamp (helio-preview.js, heliotrace.js, ~2,000 lines) renders internal reflections and an optional wall bounce, so the dashboard preview resembles the physical object rather than a flat grid.
  • A Pixelblaze pattern interpreter (PixelblazeCompatEffect.h, ~1,300 lines) runs Pixelblaze-style patterns on the device.
  • An ambient-light service (BH1750 over I2C) publishes a brightness target that drivers consume, for automatic brightness.

  • A curated WLED preset player keeps source effect IDs, names, speed/intensity values and playlist order as data, rendered through this project's own palette and light-buffer primitives.

  • Branches: only codex/helio-private-wip moved (2026-08-20). The other seven have been dormant since July.

Checked: commits on main for 2026-08-01..2026-09-01 (0; main last moved 2026-07-09); commits on all 9 branches for the same window, filtered to fork-authored work (1: a649bd47 on codex/helio-private-wip, 2026-08-20, 139 files; the branch's other August commits are upstream MoonModules/projectMM carry-forward); no commit on any branch between 2026-08-21 and 2026-09-01; releases published (none); issue search repo:Funkelfetisch/projectMM is:issue created:2026-08-01..2026-08-31 and the same with closed: (0 results each, the repository has no issue tracker activity).

July 2026

Six feature branches opened, none merged to the fork's main, alongside a carry-forward of our own next-iteration. Each is a self-contained proposal against this project rather than product work:

  • Automatic firmware updates, the device polls a JSON manifest, checks the advertised version, chip family and flash offset against its own build info, and starts an OTA with SHA-256 and expected-size verification. Manifests over plain HTTP or without a declared size are refused.
  • BLE WiFi provisioning, credentials over Bluetooth using Espressif's wifi_provisioning component, gated to run only while the device is in access-point fallback, in its own firmware variant (it costs roughly 320 KB of flash).
  • WiFi reconnect handling, a debounce before applying typed credentials, and repeated station retries before falling back to an access point.
  • RMT LED output over DMA, enables the DMA backend for WS2812 transmission on chips that have it, with a completion callback instead of a blocking wait, so a delayed interrupt under network load cannot stretch a bit cell into visible flashing.
  • RGBW colour correction, a wider set of channel-order presets, and an explicit white channel taken from the source when the layer carries one.

  • Frame pacing, a target-frame-rate cap on the scheduler, work-time metrics, and a periodic-tick sweep spread across ticks rather than run in one burst.

  • Branches: codex/upstream-auto-update-manifest (07-11), codex/upstream-network-sta-reconnect (07-10), codex/upstream-rmt-rgbw-performance (07-10), codex/performance-frame-pacing (07-11), codex/universal-ble-provisioning (07-13), codex/helio-private-wip (07-10, initial WIP), next-iteration (07-10, a carry-forward of our upstream branch). main last moved 2026-07-09.

Checked: commits on main for author-date 2026-07-01..2026-08-01 (2, both upstream carry-forward); commits on all branches vs MoonModules/projectMM@main for the same window (11); releases published (none); issue search repo:Funkelfetisch/projectMM is:issue created:2026-07-01..2026-07-31 and the same with closed: (0 results each).

June 2026

  • Gyro / IMU input, an MPU6050 accelerometer and gyroscope read over I2C, publishing angular rate plus pitch and roll as read-only values, with a desktop simulation so the interface shows live numbers without the hardware attached.

  • Branches: feature/gyro_module (06-05). No other branch activity.

Checked: commits on all branches vs MoonModules/projectMM@main for author-date 2026-06-01..2026-07-01 (1); releases published (none); issue search repo:Funkelfetisch/projectMM is:issue created:2026-06-01..2026-06-30 and the same with closed: (0 results each).
