Adds CLOCK_90 and the nixie595.ino driver: two 74HC595s on hardware SPI (GPIO13/14, latch GPIO15), multiplexed from an IRAM-only timer1 ISR. Neon dots on P1; P2 is the decimal-point line on this board. Also: - NeoPixel on any ESP8266 pin via bit-bang (GPIO12), and take the pin back after SPI.begin() claimed it as MISO - ArduinoOTA (USE_ARDUINO_OTA), with an OTA upload env in platformio.ini - DST: EU end date (last Sunday of October) instead of the first Sunday of November, and recompute the time from the rules when DST is toggled instead of shifting it by 1 h - forward declarations so PlatformIO's .ino conversion compiles - FIRMWARE_SERVER can be overridden; empty for CLOCK_90 Verified on the clock: tubes, order, dots, LEDs, LDR, NTP time with DST.

ESP_UniClock for the NixieIN12v2 clock
Firmware for this clock, based on ESP_UniClock by
Peter Gautier (GPL-3.0-or-later), vendored from upstream commit 1189810 (2026-09-07).
ESP32_UniClock2/: the upstream sketch folder (all.ino/.hfiles and the web UI indata/). It keeps the upstream layout, so it still opens in the Arduino IDE.lib/: the library versions bundled upstream (libraries/*.zip), only those the ESP8266 build needs. The upstream manuals, datasheets, photos and ESP32-only libraries were left out.platformio.ini: PlatformIO build for the ESP-12 (4 MB flash, 2 MB SPIFFS).
Local changes are separate commits on top of the import (git log -- firmware/uniclock).
Build and flash
pio run # build
pio run -t upload # flash the firmware over COM7
pio run -t uploadfs # flash the web UI (data/) to SPIFFS
pio device monitor # serial log, 115200 Bd
The CH340C adapter has no auto-reset: before each upload, hold GPIO0 to GND, tap RST to GND, then
release GPIO0. See CLAUDE.md in the repo root for the wiring.
