These files are under EUPL-1.2 license. You can use them as is, without
any guarantee.

The 100Ω resistor must be adapted in function of your WS2812 strip
and your level shifter board.

Each lithophane panel is 108x78mm including 4mm border and 3mm thickness.
Do not forget to create positive images, not negative ones.

You need :

- `2 push buttons <https://www.reichelt.de/de/en/miniature-push-button-on-0-5-a-24-vac-black-t-250a-sw-p19987.html>`_;
- `1 power button <https://www.reichelt.de/de/en/rocker-switch-round-1x-on-off-ws-r13-112-aaaa-p105442.html>`_;
- `1 WS2812 strip <https://www.reichelt.de/de/en/led-strip-digital-rgb-150-leds-5-m-ws2812b-opt-st4491-p260970.html>`_
  (cut four strips of three leds for each lantern);
- `1 D1 Mini <https://www.reichelt.de/de/en/d1-mini-esp8266-v3-0-d1-mini-p253978.html>`_;
- 1 level shifter (sorry, I lost the link...);
- 2 resistors of 1kΩ;
- 1 resistor of 100Ω (must be changed in function of strip and level shifter);
- 1 capacitor of 1000µF;
- `1 barrel connector <https://www.reichelt.de/de/en/barrel-connector-panel-jack-central-installation-i-2-1-mm-hebl-21-p8524.html>`_;
- `1 power supply 5V >2A <https://www.reichelt.de/de/en/plug-in-power-supply-unit-12-w-5-v-2-4-a-ea1012ahes501-p293278.html>`_.
