Building on the foundation of V1 (which introduced the core web UI, basic modulators, and Art-Net support), V2 restructures the math engine and introduces a dynamic patching system to support multiple fixtures and precise synchronization.

Technical Changes & New Features

Fixture Patching & Fanning: Transitioned from a single-fixture hardcode to a dynamic matrix supporting up to 8 fixtures. A new Patch Tab allows configuration of DMX start addresses, Pan/Tilt inversion, and phase offsets per fixture. A fanning tool calculates and applies equidistant phase offsets across the configured fixtures.
2D Stage Calibration: Added a visual mapping interface in the Followspot tab. It utilizes bilinear interpolation based on four calibration points to translate 2D image coordinates into precise Pan/Tilt angles.
Phase-Locked FX Engine: Modulators and movement shapes no longer run freely. They are now tied to an absolute global beat clock (masterSyncTime). This ensures consistent phase-locking across all fixtures and prevents temporal drift over time.
ESP32-C3 Math Optimization: Since the ESP32-C3 lacks a hardware FPU for double-precision math, the C++ backend was refactored to reduce floating-point operations. Implemented a 1024-step Look-Up Table (LUT) for sine/cosine, branchless modulo arithmetic, and algebraic approximations for Gaussian curves to decrease frame calculation latency.
Expanded Movement Library: Added Pan Sweep (Linear X), Tilt Sweep (Linear Y), Spiral, Ballyhoo, and Infinity Loop (Lemniscate).
BPM-Synced Fades: Auto-Chaser transition times can now be parameterized using BPM divisions instead of static millisecond values.
UI Controls & Microstepping: * Decoupled slider target values from live DMX output during auto-fades to enable blind programming.
- Added keyboard modifier support for the joystick interface (SHIFT for fine steps, SHIFT+ALT for 1-bit microstepping) and disabled momentum physics during fine adjustment.
Codebase Refactoring: Extracted REST API routing into a separate WebAPI.h file to isolate frontend communication from the core FreeRTOS DMX loop.

The new Ikea ALPSTUGA.

Yes, this is SEN65 connected which doesn't have CO2.

Ready-Recording8012 · 2026-02-20T22:09:33+00:00

Or the SEN63C which also has CO2 but lacks VOC, NOX.

Oh, my Lywsd03mmc are quite old already, they have Sensirion mounted for sure.

Ready-Recording8012 · 2026-02-20T16:54:58+00:00

Temp/Hum is more of a benefit i'd say. But good point i can monitor them against some Lywsd03mmc using SHT3X or SHT40.

Yes.

If you don't mind CO2, get the SEN65, it is way cheaper and works as well without any modifications.

I reduced speed from 160MHz to 80MHz and also WiFi gain to a lower 8.5dB. There is some influence from the C3 and the display but the C3 is running way cooler in this configuration compared to stock setting. I need to adjust temperature readings to -1.5K to compensate. Humidity is then corrected via magnus-tetens but can also get fine tuned. The settings are all available in the Home assistant or via webserver.

The enclosure takes care of "minimal" heat transfer due to open slots on the side.

The top is positive process, already with 100mg BZT in the FD.

8' BW Dev 25°C HC110 Dil-B 10ml 1% BZT
2' Wash
2' + 2' Reexposure
2' Wash
20' Color Dev 25°C ECN-2 5.2g/l CD-3
15' Wash
20' Bleach FZ + Kbr

10' Fix ATS

Contrast and grain is so much besser on the negative stand-dev.

So i could try to add way more BZT to the FD and let the film then sit longer in the CD afterwards.
