Teensy 3 OctoWS2811 code for Glediator led matrix software

Here is a simple working example sketch for using Glediator with OctoWS2811 library, and some guidance on setting up. To get Glediator running, you need to install two files that allow java applications to communicate via the computers ports. The two files you need are: librxtxSerial.jnilib and RXTXcomm.jar you can download these files from the RXTX site, and also find further help on installing, although I did not find the help so helpful. The […]

video screen capture to Teensy3 led matrix / array

how to set up pixelcontroller to capture screen

I have been using the great Pixelcontroller software to capture moving image from my laptop screen and sending it to a teensy3 led pixel array. The pixelcontroller software is free, and you can get it here: to set it up for screen grab in real time so that you can display video and whatever is on your screen on the pixel array you need to do a couple of things first: for screen capture using […]

UTFT touchscreen SD file selection buttons with Teensy 3

utft sd file touch selection

So, I am hoping to use this system with my light painting kit. I want to be able to select a file from the sd card on the fly. To do this, I have made a sketch using Henning Karlsen’s UTFT library. But, I have adapted it to make on the fly buttons, so that all files on the sd card can be scrolled through, shown on the screen, and then selected at the touch […]

Go take a look at Teensy microcontrollers

Using the Teensy with led strips for pixel poi

If you haven’t yet done it, go and have a look at the Teensy micro controller from PJRC. Its powerful, small, has lots of libraries available and, one very large bonus, a very friendly developer and user community forum. You will usually find someone who can point you in the right direction or perhaps even provide an answer to something that has been holding your dev back. I am not associated with teensy, I just […]

Artnet (art-net) and micro controllers

wiznet 820io module based on 5200 chip

I finally have artnet working with the Teensy 3 micro controller / development board. The result is a simple and cost effective way to control led lighting from your computer via the ethernet cable output. Using this set up you can control hundreds of leds, output video to leds, or whatever. You will need to use some software on your computer as an artnet output, I use pixelcontroller. This is free and robust, and fast […]

Wireless control of Led matrix using Teensy 3.0 and adafruit cc3000

teensy 3.0 micro controller with CC3000 breakout board

This is a small project to control an led matrix using wifi, set up to go over a local router. The idea is simply to have a system whereby the led matrix will play animations from software running on a computer that is further away from the led matrix, or where using cables is not wanted. The set up currently works for an array of 8 by 30 leds and uses the freeware pixelcontroller software: […]

light painting

a quick first attempt to photograph the light staff

Light painting seems a logical progression to the led pov sticks. As the WS2811 leds aren’t too good for the POV work, I thought that I may as well use them for something else. They are fine for use in slower moving projects and static projects so I put together a light staff for light painting: Take a look at the light painting page where I will post some images and a description
