Introduction: RGB HexMatrix | IOT Clock 2.0

About: I am a Computer Science Student. I love playing with electronics and codes. Making Brand new projects.

HexMatrix 2.0 is a upgraded of previous HexMatrix. In the previous version we have used WS2811 LEDs by that the HexMatrix became heavy and thick. But in this version of matrix we are going to use custom PCB with WS2812b LEDs which made this matrix to be 3 cm thin.

Step 1: Supplies:

Step 2: 3D Printing:

  • Click for STL files
  • 3D Print all the 3D models, make sure to print the screen in white PLA.
  • The design I made is for hanging on the wall you can modify as per your requirement in Fusion360 Fusion360 file.

Step 3: Circuit Connection:

  • Solder all the LEDs on PCB in correct order.
  • Make all the connections as shown in circuit diagram.
  • GND~GND
  • Vin~5V
  • D2~Din

Step 4: Code:

  • Open the code given in Arduino IDE. Click for Code
  • Install the FastLED Library and board library for ESP8266 boards.
  • Type your Wifi_Name and Password

//Your Wifi info

const char* ssid = "Wifi_Name";

const char* password = "Password";

  • Enter the time zone of your country

//Your time zone

int timezone = 5.5 * 3600;

  • If say for me in India time zone is 5:30 I have typed 5.5,similarly you have to put time zone of your country.
  • Select the Board type as ESP8266 (NodeMCU),select the port and upload the code.
  • After the code is successfully uploaded check the Matrix by powering it with micro USB adapter.
  • You can even display animations from FastLED library examples.

Step 5: Final:

  • Cut the legs of the NodeMCU board and put everything in the enclosure.
  • Put the screen and make some holes with drill and screw the sides.

Do you have the project files instead of the gerber files? I wanted to add a resistor and capacitors to aid in not flickering. Also wanted to add a different board that is mounted on the back of it

I think you used easyeda for this? Do you have the original schematic or did you just drag a load of them onto a shape? Just curious?

This shows 5v going to the ESP8266. I thought it was only rated for 3.3v?

thought to manufacture the grid with wood and shell by CNC it? This should print less expensive than 3D

You can provide lower PCB source file? I am going to try to coordinate SMT placement needs thanks again

I have designed the PCB in EasyEDA. The gerber file is provided above in step 2.

I'm glad you have been able to reply to me. I looked PCB diagram, found some minor problems! I do not mean to offend you, but I hope your work is getting better, I hope to help to you!

Power line is too thin, and because the use of an even line led all the connection, may result in too large a pressure drop, the power input from the RGB lamp operation far not normal.

VCC and GND recommended way to shop copper

Can be measured at the power supply voltage is furthest from the RGB light, to see if such a situation occurs.

My English is poor, there may be some expression does not please understand! Have any questions, please give me a shout, we promptly exchange! I wish you a happy life

Ok , actually this was my first PCB design. I think you mean we can have copper layers for GND and VCC instead of this wire. It would be great if you can help me with this so that I can implement the same in my upcoming projects.

Even I am bad at English 😁, Thank You
