WHITE COMMON CATHODE LED MATRIX HOW TO

For the kit, we purchase super bright clear LEDs and sand blast them ourselvs to diffuse the lens. A diffused lens will give you a wider viewing angle, especially for side viewing, so keep these things in mind if you’re purchasing your own LEDs. Rectangular/oval shaped LEDs can be used, but may be a problem to hold during construction. LED, showing lengths of cathode and anode leads.

The LEDs are round and measure 5 mm (T1-3/4) (see Figure 4).įIGURE 4. Physical dimensions are approximately 2.5” x 2.5” x 2.5”, with consecutive LEDs separated by 3/4”. There are four LEDs across the length, width, and height. The LED cube has 64 LEDs in a 4 x 4 x 4 matrix (see Figure 3). Jig kit including wood base, LED holders, spacers, nuts, and bolts. The jig contains the following parts: wood base four 1/4-20 bolts, four inches in length 16 1/4-20 nuts 12 LED holders (two styles) and 12 spacers. If you do not wish to use a jig, you can fabricate the LED matrix in any manner you find convenient. Instructions for using a jig are provided in this article. To accurately build the LED cube matrix so that everything is evenly spaced and aligned, I recommend building the jig described here.

20 gauge solid wire one meter in length.

We will need the following tools for building both the LED cube and jig:

Of course, you can also source the parts yourself from the parts list at the end and instructions on how to program the 3D matrix yourself are provided here also.

Runtime for all 29 patterns is approximately 6-1/2 minutes. There is a kit for this project available from our webstore that includes a microcontroller with 29 pre-programmed patterns that automatically play.

You have a choice of four monochromatic colors: blue, red, green, and yellow ( Figure 1).
