ACTIVE is a sculpture of light built with Evan Miller. To entice the imagination and wonder about objective vs subjective reality.

Active

Lightning 10 gross LEDs begins in the one of a kind video art experience for visitors to The Source.

Giant expansive space high above the patrons is sparsely populated for creative expression. bring a local flavor of of collaborative expression to a focal point below.

Reacting to your motion as you enter the space; Sensors, video, images, and the live data from the internet are all merged to creating a living space above The Source, an urban marketplace in the Rino Arts District.

SRC

applications for rendering content to Open Pixel Control network stream.

depends on FadeCandy C Libs for opc client and effects framework. we've added some custom effect mixing and image loading for realtime brightness control.

[optionally] depends on BlackLib for live analog brightness control sensors.

STREAMERS

opc content generation for testing troubleshoot and user contributions in mostly Python from opc/fadecandy examples

PROCESSING

Toolkit for developing image manipulation code, layouts, and renderings for concept art in Processing

processing simulation

BIN

tool kit for running and configuring beaglebone black

Installation

Materials

• 2x the latest BBB or upgrade any version to debian
• tlc spi style led drivers (tlc5947, http://www.ti.com/product/TLC5955, tlc5940 tlc59711 )
• analog input on AIN1

Steps

Pulling the latest and Building

mkdir git; cd git
git clone https://github.com/mpinner/Active.git
cd Active/bin/
chmod +x *.sh
. ./env.sh
./setupEnv.sh

my openpixelcontrol fork with SPI / TLC support

git clone https://github.com/mpinner/openpixelcontrol.git 
cd openpixelcontrol
make

change hostname

sudo emacs  /etc/hostname
sudo emacs /etc/hosts

Setup root crontab for script autorun

sudo crontab -e 

Add in the following

# push-sparkdata.sh
00 11,23 * * * /home/debian/git/Active/bin/push-sparkdata.sh >> /var/log/active-push-sparkfun.log   2>&1

# starts spi overlay gpio pins
# creates /dev/spidev* files
@reboot /usr/bin/python -c "from Adafruit_BBIO.SPI import SPI; SPI(0,0)" >> /var/log/active-gpio.log 2>&1

#pre-process videos 
#(with some large videos bbb cannot transcode in realtime)
*/1 * * * * /home/debian/git/Active/bin/process-videos.sh >> /var/log/active-process-videos.log   2>&1

# on boot start whatever this bone id configured for
@reboot /home/debian/git/Active/bin/run.sh >> /var/log/active-monitor.log 2>&1

Edit /etc/fstab to make for less disk
