Hey Guys

I released "Cevian Raspberry" on the Swiss Demoscene party Demodays 2013 this weekend. I used Processing 2 to create the realtime animation, see https://vimeo.com/72928093 for a video. I also released the (ugly) code on Github.

Cheers

Hey

I did a short video about my latest installation. I used Kinetic Space (created in Processing) to recognise gestures. Kinetic Space talks to an adapter application (also created in Processing) via OSC. This adapter application then controls my PixelController LED Matrix software.

All my code is released on my Github site.

Hey I just started playing arround with the shader and have a strange issue. The code fragment that causes the trouble is here:
1. void main() {
2. vec2 vUv = glitchOfs+vec2(vertTexCoord.s,vertTexCoord.t);
3. while (vUv.x > 1.0) vUv.x -= 1.0;
4. ...
This code works fine on my mac book air (2012 model) using processing v2.0.1. I tried to run this code on my win64 machine (NVIDI NVS 3100M) using processing v2.0.1 and it fails with the error message:
1. java.lang.RuntimeException: java.lang.RuntimeException: Cannot link shader program:"
(stacktrace at the end of this post). when I change the while (vUv..) into a if (vUv...) it works (at least it doesn't crash). As the error is thrown by the JOGL framework I think its a) a driver issue or b) a jogl issue.

does anyone have a clue what causes this error?

Hey all

I just published a new showcase video for the upcoming PixelController release.

https://vimeo.com/61141493

PixelController use the Processing libraries and allows Processing Sketches to send image content to PixelController (using the OSC protocoll).

Hope you like it!

Hey Guys

I created a Processing application to control eight 80cm high wooden letters filled with 110 Led modules. Those letters are used as stage design for some friends which founded a band.

I created a blog post about the whole project at http://neophob.com/2012/11/kalikut-now-stage-design/. I released the whole code on GitHub.

Hope you like it.

Hey Guys

I released StripInvaders, a ethernet enabled LED Strip with a OSC interface, some days ago. I also wrote a litte PureData script to configure the LED Strip. However, that was not that user friendly. Thats why I wrote a little GUI to configure the LED Strip:

ControlP5: Mix Tab Elements and "always visible elements"

Hey all

I really like the controlP5 library (I use the latest dev snapshot release). However I didn't figured out how I can mix tabbed elements and "static" elements.

To illustrate my needs, I want some drop down lists, which should be ALWAYS visible. And there is a tabbed area, where different elements are shown.

can someone guide me into the right direction?

cheers and thanks

Hey guys

I just published my Processing.org based Led Matrix controlling software. As a video says more than 1000 words, check out: http://vimeo.com/27453711.

The software is using alot of processing libraries (Network, PImage, PApplet...) and is published on GitHub: https://github.com/neophob/PixelController

The Rainbowduino contest is running now, check http://wish.seeedstudio.com/?cat=27 for all entries.

I submitted two Projects:
- ze_invaders (space invaders on huge RGB matrix): http://wish.seeedstudio.com/?p=271
- ze_blinker (blinkenlights movie player on 4 Rainbowduinos): http://wish.seeedstudio.com/?p=31
A Rainbowduino is at atmega328 uP to drive a 8x8 RGB LED matrix. I wrote a Processing library to control the LED matrix from Processing.

The ze_blinker project use my blinkenlight movie player Processing Library.

Hope you like it, cheers

From Processing via Arduino to an RGB Matrix

Hey guys

I released a nice library to control one or more rainbowduinos (from seeedstudio). A rainbowduino is basically a driverboard for a 8x8 RGB Matrix. rainbowduinos can be chained using the I2C protocol.

The library contains firmware for arduino, rainbowduino and a processing library and can be found here: http://code.google.com/p/neorainbowduino/.

I wrote a blog entry about it here: http://www.neophob.com/2010/09/neorainbowduino-processing-library/.

And if you want a in action video, check http://vimeo.com/13139475(rather old version)

Hey guys

I just released my neorainbowduino package. It contains firmware for rainbowduino (from seeedstudio) and arduino, and a Processing library. Send a 8x8 pixel frame to your rainbowduino. I also provided two examples, how to use the library.

I published more information at my blog: http://www.neophob.com/2010/09/neorainbowduino-processing-library/

maximal serial speed (rxtx lib)

hey guys, I just wondering whats the maximal serial speed for the rxtx lib is. I communicate with my arduino - using 115200 bauds no problems - using 500000 bauds I only get an gnu.io.UnsupportedCommOperationException : Invalid Parameter.

I glanced at the rxtx source, SerialImp.c and It looks like rates up to 4000000 baud are supported. any hints?

I use MacosX 10.6 and the latest rxtx libs (2.2pre2) and the latest stable processing libs.

cheers
