Alexa Enabled - WLED Lithophane Lightbox Cube (100x100mm Lithophanes)

An elegant lightbox for your lithophanes.

There are 2 variants available:

1. WLED based

This variant is designed to be used with an ESP8266 running WLED and an addressable LED strip (WS2812B). This option is great as it means you have the ability to control the colour and brightness of the LEDs, patterns and also integrate the lightbox with Alexa. This means you can use Alexa commands like “Alexa, turn on lightbox”, “Alexa, change lightbox colour to green”, or “Alexa, change lightbox brightness to 50%”. This version with require you to do some soldering.

This version is powered by the micro-USB port on the ESP board.

2. Battery powered-tealights or similar

This variant has a 50mm hole in the base so you can place the lightbox over a battery-powered tea lamp or similar. This is a good option if you don't want to do any soldering.

Parts required:

You could try printing dowel pins if you don't want to use metal ones)
