Step 3: Wiring It Up - Power to the NeoMatrices

Sorry no schematics here yet - will draw and add some hopefully in the next few days.

Two things to point out. First, we wired our matrices for power in a parallel circuit - meaning each matrices was wired for power from the source, rather than passing current from one matrix to the next. Second, we soldered a capacitor between the 5v and ground terminals on our DC power jack. According to the literature, this capacitor protect the LEDs from the initial onrush of current when we supply power.

1) We read the following guide several times https://learn.adafruit.com/adafruit-neopixel-uberguide/power

2) Soldered our capacitor between the + and - terminals of our DC power jack.

3) Soldered wires to the + and - terminals of aforementioned power jack.

4) Split both + and - wires three ways, soldered, and wrapped in electrical tape

5) Soldered a + and - wires to the 5v and ground pads on each NeoMatrix.

<p>Hey ... gud work !</p><p>How to get this working with Dot Matrix Displays that are available in market ?</p><p>They are equipped with 16-pin header for connection to controller board .</p>
Been looking for something like for awhile. Wanted to something bigger. 3x3 foot picture frame but this is a great start to get me going! Thanks will try
<p>Nice job! How did you put the youyube videos with autoplay and with no border and no controls?</p>
<p>Thanks! I followed this steps in this very helpful Instructable - https://www.instructables.com/id/Using-Youtube-psuedo-GIFs-to-an-Instructable/ :)</p>

<p>Woah! I want to make something similar in my high TV cabinet! I don't know if you read my mind or I read your instructable before! ;-)</p><p>Many thanks for the ideas and solutions!</p>
<p>Might be more tempted to hook it to a parallel port of a headless server.</p>
<p>not sure I follow? you mean connect the LED boards directly to the server?</p>
<p>yes.</p>
<p>I got a couple of graphical VFDs out of some old medical equipment (<strong>Noritake GU256x64-39)</strong> I've been meaning to do something like this. Also pretty simple with a USB cash register pole</p>
Want this!!!!!
<p>you should make one!</p>
If I could high five you I would.
<p>haha thanks!</p>
