Minecraft Cube Light

 Thingiverse has a lot of neat stuff.  My son found a Minecraft Diamond Ore Lamp and decided that he wanted one.  I see that the creator has some links to tutorials and whatnot, but I saw them after the fact and did things a bit differently.  


Ultimately, I threw WLED onto an ESP8266, added 5 Neopixels, some Vellum as a diffuser, and called it good.  The neat part of this was being able to add a single IFTTT command to be able to change the colors via Google Assistant/Home.  

All of my home automation stuff through Google Home goes through an external service such as IFTTT, then to a secure bridge that I've designed on the backend.  The command goes from Google to IFTTT to my server to the IoT device.  I was able use IFTTT's "phrase with a single text ingredient" to call multiple different states of the LED block.  


Here are some examples of diamond, emerald, redstone, gold, lapis, and iron.   









Here are some images of the build process. First, there is the printed cube with vellum glued to the inside.  

                            

                                


The system is run by a NodeMCU ESP8200 board. 


Here's a video of the system in action with the cycles sped up to show the colors.
