After tiding up my cupboard, I came across a project that I had made about three years ago. It was the "CUBE LED with Neopixel Matrix panels WS2812" by IeC and used a Arduino Nano to paint patterns on three 8x8 RGB WS2812B matrix panels controlled by a IR remote control. It seemed like a good project to upgrade. I decided to replace the Arduino Nano with a WeMOS module and to control the cube from an Internet Browser.
VideoThere is only one file to slice and print. You can either do this using the Slicer software that came with your 3D printer or take it to a commercial 3D print shop. I used a 0.2mm layer height and no supports.
BuildThe actual hardware is very simple. It basically consists of a 5V regulator module and a WeMOS D1 R1 module. I added two physical buttons to control the brightness, although in hindsight, I shouldn't have bothered as it is enough that you can control the brightness from the Browser interface over WiFi.
Schematic of the cibe
I did design a PCB. As the circuit is so simple, you can just use a piece of protoboard instead. Eagle files have been included should you want a commercially made PCB or if you want to make one yourself. I used the Toner method to make mine.
Optional PCB
I used JST plugs and sockets but you can solder the wires directly to the board. The PCB is held in place with hot glue. The WS2812B panels are held in place using double-sided tape. I suggest you hold off fixing the panels in place until you have the software running. This is so you can get the correct orientation for each panel.
PCB hot glued to case.
Final Assembly
The software configures the cube as a Web server. After you have uploaded the software to the WeMos using the Arduino IDE, invoke the Arduino IDE console at 115200 baud.
When started, the WiFi Manager will try and connect to your WiFi network. If it can't be found or this is the first time you are running the software, it will create a WiFi hotspot called NeoCubeLampAP. Using your phone, connect to this WiFi hotspot. You will be presented with a menu. You can either select your network SID from the list or enter one manually. You will be asked for the password if it is required.
Once connected, the Ardunio IDE console should show you the IP address that your router has assigned. You can now use this IP address to connect to the cube. Open the browser on your phone and type in http://[assigned_ip_address] into the address bar. eg: http://192.168.10.107
Interface as seen in an Internet Browser
I used a modified form of the WS2812FX library. This had all the code necessary for the Browser interface as well a number of built-in animations. It made the coding easier. The down-side is that it uses the Adafruit NeoPixel library. This library is a lot slower than the FastLED library which meant limiting some of the animations that I had originally planned.
/*
ESP8266 NeoPixel Cube Control
This program is based upon the web interface example program from the WS2812FX library
by Harm Aldick (www.aldick.org) which allows the mode, color, speed and brightness to
be controlled over the web.
This program also uses the WiFiManager library to allow WiFi credentials to be set
via a web interface.
This program also uses the ArduinoOTA library that allows the ESP8266 ModeMCU's program to be
updated wirelessly. That is, without having to attach a USB cable to reprogram it. This
is important because the NeoPixel Tree is fairly fragile.
