Introduction: WS2812B Light Panels

About: Hi, my name is Andreas, I am 18 years old and I like to make stuff.

Hi, today I gonna show you how to make your LED panels like the nanoleafs.

For this project you need:

  • Some plexiglas (40% translucent)
  • 12x WS2812 LEDs & 12x 100nF Capacitor (SMD 0805(2012)) per Panel (or you can also use led strips: 60 LEDs/m)
  • 5V power supply
  • Some M3x6 screws and nuts
  • Aluminium Tape / Foil
  • Thick paper
  • Silicone & glue stick & glue
  • Some 3 pin wire
  • 3.3V voltage regulator
  • ESP-01 module
  • Some filament for the 3d printer


  • 3D printer
  • soldering Iron

Step 1: The Construction

As my other designs, my led panels are very simple.

You use only a few parts to build this. The Assmenly is also ver easy.

The panel itself consists of 2 3d printed parts, a piece of plexiglas, 3PCBs and a cover made out of paper and aluminium foil for a better refelction.

Step 2: The PCB

After designing my panels in SolidWorks I used Eagle to create my own PCBs.

The PCB design is very simple it contains 4 WS2812B LEDs and 4 100nF capacitors.

Here can you find the gerber files:

After designing my PCB I orderd it on JLCPCB with a thickness of 1mm and with white soldermask.

I ordered the LEDs and the capacitors at LCSC for a very good price.

Step 3: 3D Printing

After the design phase I started to print the parts with 3d printer and white PLA Filament.

For both parts I used a layer thickness of 0.2mm, 30% of infill and for case you have to use support material.

Step 4: The Frontplate

My frontplates are laser cutted from 2mm thick plexiglas (40% translucent).

But you can also cut it by yourself.

I addition to plexiglas you can also use thin polystyrol panels.
