Luminance, an Arduino compatible hardware platform to enable anyone to easily explore interactive illumination.
Let there be light!
Programmable, controllable, motion reactive light - doing your bidding and accentuating your every movement.
Welcome to my Kickstarter project. I hope that you will be as excited about the possible applications of the Luminance platform as I am about designing and building it. Luminance is the core of a reactive lighting system that will make developing reactive lighting not just possible but easy and accessible to anyone. Luminance makes the step from inspiration to implementation simple while still serving as a platform for extended hacking, well beyond its base functionality.
How it Started
The concept was spawned at a club by a cheap disposable flashing light that happened to have a fiber optic plume stuck on the end. I was dancing with the strobe in my hand, watching the light trails and found that the strobe would occasionally sync up with the beat of the music. I was loving the effect of the visual elements perfectly complementing the ambient sound. I found myself mesmerized by it until the point that the random flashing lost sync with the music and went back to being just a blinky light. My thought was to add an accelerometer to synchronize the strobing to my movement which would (in theory) synchronize the strobe with the beat of the music.
How it Got Here
While the initial goal was just to build a simple sensor into a strobe after sharing the idea with the members of my hacker space (crashspace.org) it was quickly expanded upon and improved. With ideas and applications formed in the crucible of hacking, making and innovation that is Crashspace, the Luminance platform turned into so much more and I thank all of my friends and fellow hackers for their input, inspiration and support.
The initial prototype was built using an Arduino, accelerometer, RGB LED and the original fiber optic plume from the club. Then someone suggested that it could be programmed to "wave out" the colors of the rainbow. This lead to an exploration of the intersection between color space and the motion sensed by the accelerometer. Prototyping continued with a variety of Arduino boards, brainstorming and exploring the sensing possibilities (accelerometer, gyro, thermal, mic) and different types of light output (RGB LED, single color LEDS, strips of high voltage LEDs, strips of individually addressable LEDs, smart LEDs systems like the BlinkM). It quickly became clear that this system deserved to be so much more and was really the core of a development platform allowing anyone interested in the interaction of movement and light, to explore applications of reactive lighting. That I already found myself re-purposing the base platform components to explore new applications of the technology drove that point home.
This Kickstarter project was created as the next step in development of the Luminance platform, bringing together the support and resources to design and manufacture the core components of the Luminance system. This project will generate the base components to enable a rapid transition from concept to implementation of reactive lighting systems in the manner that an Arduino development platform is ideally suited. The rewards for this project will be the necessary components ready to immediately be incorporated in your projects.
Things to Try
Possibility 1: Just open the box and switch it on. All rewards that are shipped will be preprogrammed as reactive systems straight out of the box. Take the sound reactive system straight out of the box, switch it on, set it on the table (or better yet on a speaker) and watch it react to to the music.
Possibility 2: Take it to the next step and easily update the behavior. No need to write the code yourself since examples will be available for download. Grab the Arduino development environment (following simple instruction that will be provided to download and installing it), grab one of the example sketches, plug in the USB cable and drop it on the device.
Hosting a party for Halloween, grab an example with lots of orange and red responses, put it in the middle of the table and watch a light show created by the sounds of Halloween. Examples will be posted with suggestions on cool uses for them.
Want to spin Poi but concerned about lighting the curtains on fire, swap the spectrum shield for an accelerometer shield, drop the motion reactive "fire" sketch onto the device, tie on cords and start spinning. Watch the "fire" respond to the motion, flaring up and dying down. Try them all and find the ones you like best.
Possibility 3: Hack the software to do your bidding. Using the examples as a starting point or starting from scratch you can make the system react to movement or sound in any way that you can imagine. It is, after all, an Arduino compatible system meaning that it is designed and super easy to hack the code. If you have not used an Arduino before this is a great way to start, you will likely be surprised at how it makes "complicated" microcontroller development easy and accessible.
Possibility 4: Hack the hardware, hack the software, pwn the system. Start with the prototyping board or rework the others. Explore the obvious applications of the Luminance Platform to illuminated motion reactive clothing. The possibilities are limited only by your imagination, dream of an application, grab the hardware and make it come to life. Simple, fast and easy reactive lighting development.
Beyond the obvious applications of the Luminance Development Platform, what really excites me, is the opening of doors to the exploration of the amazing things that can be easily achieved when a simple to use Arduino based microcontroller, a sensor and some LEDs are combined into a package that makes it trivially easy to get from inspiration to implementation. Luminance makes the development of reactive lighting systems not only possible but easy and accessible by anyone. The applications of the Luminance development platform are numerous and I look forward to the amazing applications that others will come from the community that extend far beyond anything that I can even start to envision.
Throughout this kickstart, I will post video updates showing interesting applications using the Luminance Platform prototypes. I hope they will spawn ideas for applications of the Luminance Development System to possible projects and show the types of projects that it will enable for you. Check back thorough out the kickstart to see more of the things that the Luminance system can do.
The Technical Bits
At it's core the Luminance platform is a fully Arduino compatible platform. Add to that carefully designed sensing and output shields designed to interface both electrically and mechanically with the main board.
The Hardware Bits

Open Source Hardware
This is an open source project and all hardware will be open sourced at end of project. In addition to that I plan to go through the process of getting the hardware accepted as an official Arduino platform.
Per Arduino project policy, I will begin the discussion with the core Arduino development team as soon as the project kicks off to start the process of getting the hardware accepted as an official Arduino platform. Submit all necessary source code for supporting the platform for inclusion in the main Arduino code. Provide final hardware to the core Arduino team for validation that it functions to the standards expected of an Arduino platform. The hardware will be manufactured under fair labor conditions. If all goes well, I can update all the documentation from "Arduino compatible" to the "Arduino Luminance' platform.
While the 3D printed stand and mounting clips are only available during the kickstart, the designs will be posted on thingiverse (as agwn) as soon as the test prints are successful. The model will be designed to fit within as many of the working area of as many printers as possible be it a Makerbot, RepRap or another design.
Getting Things Early (aka. before Burningman)
Rewards at all levels be ship out in the order of that you put your
support behind the project. I can guarantee that a minimum of 390 motion
reactive kits will be produced in the initial production run. I will be
doing everything within my power to ensure delivery of the initial
motion reactive development kits with at least a month to spare prior to
burning man. Back the project early to ensure delivery with time to
spare for integrating with your Burningman reactive lighting clothing or
As soon as this project hits its funding goal, I will be committed full time to the development of the Luminance platform. The sooner this happens prior to the end of the funding window the sooner the final kits will ship. Every day between the project hitting the funding goal and the end of the kickstart will be one day earlier that you will receive the rewards of this project.
Thanks you to all the members of CRASHspace for their inspiration and support. In particular fellow crasher Kyle for his work behind the camera. My good friend Sage for pulling the parts of the video together, filling the gaps and making it awesome. The music used found at the free music archive made by the artist c4.
Straight from http://www.arduino.cc/
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
I have chosen to make the Luminance platform Arduino compatible because my goal is for the development of reactive lighting systems to be just as easy and accessible to everyone.
The programing of this platform will use the standard Arduino IDE, the hardware will have an Arduino bootloader so any existing Arduino sketch can be easily used on this platform.
Arduino development is built around the idea that it should be possible for anyone to "sketch" out an idea and easily make it a reality. A sketch is an Arduino program. The most basic sketch has at least two parts setup() and loop(). As the names imply, setup() sets up the system and loop() just keeps on looping until you turn it off.
In an Arduino system a shield is anything that stacks on top of the main board. The Luminance platform will initially have two types of shields, sensing and light output drivers. The shield stackup will be novel with the shields interleaved to fit within a cylinder to hopefully open up new applications of the Arduino platform.
The sensing shields will include an accelerometer shield, an audio analyzer shield with others to be added in the future. Some other sensors I am looking at are a gyro to sense rotation, a MEMS compass and possibly a IMU with some combination of accel, gyro and possibly compass (this is called 9 axis sensing with 3 Sensors * 3 axis each and 10 axis if it includes barometric pressure).
The light driver shields will include one with driver circuits and high power LEDs all on one board (feed into a fiber plume) and a FET power driver shield that can either be used to directly drive higher voltage (6-24V) LED strips or to interface with higher voltage logic like the addressable LED strips.
A system with split voltage rails is designed from day one to operate with different voltage levels within the system. The core of the system needs to run at low voltage to interface with the sensors but the really cool LEDs need higher voltage to do their thing. The solution is to design the system to keep the Arduino voltage completely separate from the LED voltage. This has a number of serious advantages when you use the system. First off the controller and sensor are completely separate from the LEDs so they can go into super low power sleep modes and only turn on the LEDs (and draw all of that current) when they should be on. This system is designed for exploring reactive lighting and one of the interesting things to do with it is have a system that can sit for weeks or months waiting for something to react to and only then start seriously draining the battery.
