I helped fund a kickstarter project a few months back and I just received my 8×8 RGB123 LED Matrix reward for my pledge:It is a 64 (8X8) RGB123 Led matrix based on the latest WS2812B LEDs with two XT60 high current M/F connectors, two 3 pin headers, and a servo wire. For a $30 dollar pledge I am super happy with it and the overall Kickstarter experience.
Here is a little demo of the RGB123 LED Matrix
I have experience with the WS2801 chip from my IALED Pants project and it amazes me that only a few years later the led has the addressing ic embedded right in to it. The main differences for me for using the WS2812 over WS2801 is the WS2812 only needs one data line and can work at 8 or 16 megahertz. The WS2812 does not use the SPI protocol like the ws2801 therefore it does not need a clock line.
WS2812 LED modules run at 800khz, not the typical 400khz protocol available on ws2811 modules. This equates to twice the speed, allowing programs to communicate with WS2812 much faster. WS2811 and WS2812 require each color to be pre computed. The program can’t compute the 1st, color send it and then move to the next color. Instead, each color needs to be computed, buffered and send when all colors are computed. This can lead to a limitation depending on the controller being used. Depending on the library being used, each led typically takes up 4 bytes of EEPROM.
This isn’t as big of a limitation as one would think because you always have the ability to run multiple strips in parallel. The limit of strips is limited by the number of available pins. I recommend using ws2812 or ws2811 for all projects going forward unless you plan to use the SPI port. For instance if you wish to use a Raspberry Pi as a controller I recommend using WS2801 LEDs.
Over all I am very happy with the quality of the RGB123 LED Matrix and I hope to order a few more in the coming months. I really want to order on 16×16 matrix.
I wanted to give you guys a little demo of what I am working on for my live performances using VDMX and Ableton live. In the 1st part of this video I show a few examples of presets I configured in VDMX. Later on I explain a little more in depth. If there is an interest I can make a step by step tutorial. Subscribe, share, Like and/or post a comment if you like what you see.
Examples of What I Produce with VDMX and Ableton:
I wanted to port it over to a teensy 3 verse the Arduino Nano to achieve faster FPS and reduce the size a little more in my IALED Pants. I am currently still using the Adafruit-WS2801 Library but will be switching over to FastSPI once version two is out of beta.
Here is a demo of theTeensy 3 FPS:
Here are some pictures of the process:

The idea behind this is to use non-traditional shapes as a screen for a unique visual performance. Using Modul8 I was able to map out each side of the cube and the long rectangle as it’s own screen.
has been very easy to learn and there are plenty of tutorials all over YouTube and the internet in general. I plan to eventually synch Ableton and Modul8 together to allow me to trigger audio clips and have specific visuals designed for the specific clip play as well.
Here is the 2nd demo of my new WS2801 individually addressable RGB LED pants. The pants are lined with WS2801 RGB LED strips. The strips are controlled by an Arduino nano and powered by 4 AA batteries. I wanted to create this video quick before I add some additional features. I plan to add a microphone to code them to be noise active as well as add a pot to control the intensity of the LEDs.

Here is the prototype demo of the iPad in dash dock for my Toyota Tacoma. I am using a TomTom Bluetooth GPS receiver along with the Navigon app to provide the navigation. DashCommand is the ODB-II app the connects to a bluetooth ODB-II Transceiver plugged in to the Tacoma. The Music visualization app is called Rabbit Hole by Feldspar, I really enjoy the app but because it uses the internal mic it cases the audio to skip for a few milliseconds when open and closing the app. Once it gets a little bit nicer out I plan to redesign the dock. I want to permanently mount the iPad and create a channel for the front facing camera. check back soon to see more progress on my iPad In Dash Dock.

Here is one of my 1st tests using the serial touch screen on the BARMonkey.
