metaPixel is a simple, modular WS2812 LED-strip base LED panel. Each module contains 20 LEDs in a 4x5 grid behind a printed diffusor.

The modules are connected by D-SUB high power connectors. Magnets on the sides of the modules add stability to the connection.

I have used black ABS for the boxes and clear colorfabb XT for the diffusor foil.

Autodesk Fusion archives and STEP files are included in the zip archive.

controlled by a Teensy 3.1 using the FastLED library.

For each module, you will need:

• 1 x Diffusor + Grid either a full transparent (single piece) or glued together from grid and foil.
• 1 x Cover
• 1 x Box (there a 5 different versions differing in the position of the connectors)
• 3 x D-SUB, High Power jack
• 3 x D-SUB High Power plug
• 4 x round magnets 3x3
• 4 x round magnets 4x3
• 3 to 6 x ring magnets 6/2,2
• 4 x magnets 5x8
• 20 x WS2812 LED from a 60LED/m strip.
• wires
• glue to fixate the magnets and to glue the translucent diffusor to the opaque grid (if used)

For the full display you'll need a sufficient 5V power supply and a custom programmed controller. A commercial controller will not work as expected because the LED layout changes with each metaPixel row (see CableLayout MetaPixel.pdf).

##Building a Box:

1. mark the same pole on all magnets with a marker. This will save a lot of work. In is merely impossible to remove a false positioned magnet after it is glued in.
2. glue in all the magnets use the CableLayout-MetaPixel.pdf as a reference.
