DMX Light: One Day (Chen)

Project Name: One Day

Group Member: Chen Xiong, Yang Gao, Ying

Progress: To begin with, we are quite struggling with the use of DMX light. It is designed for the stage, and therefore it’s hard to imagine a composition with these. Then we thought about music. Since it’s designed for stage, we would just use it for the stage. We decide to choose the theme song from the movie One Day. The idea is that the music has to have a story behind, therefore we could control the light according to the movie. We picked the song, which was used in a scene when the female and male protagonists were running by the sea. It almost immediately came to our mind that each of us would take in charge of one of the DMX lights. Two lights are for the protagonists, and one for the background setting. Then ideas extend a little bit here. There’s a famous Chinese version of Romeo and Juliet called Liang Zhu, where the protagonists Liang Shanbo and Zhu Ying Tai actually transformed into butterflies after they were separated, and they committed suicide.

So we decide to use both of the metaphors. It took us some time to figure out how to gather the DMX lights into smaller light spots, and how to change the light spots. We test with different materials and ended up with cardboard. We practiced for a lot of times to make sure we do understand the function of the cardboard hoes, and how that affects the light spots. We used contrast colors for the protagonists (light spots). Ying and I were responsible for the protagonists, and Yang is responsible for the background color. If we had more time, we would compose the background better to fit with the protagonists, cause, for now, the background sometimes is too bright to make the protagonists invisible. Here’s the presentation of our work:

Week 8: DMX Project – Tiger Tian

Title   A Day in the City

Partner   Rosie Gao

Presentation Date  04/02/2019

Project Description  Considering the brightness of the DMX lights, we decided we would do something that corresponded with their big scale. Thus we came up with the sky to simulate the changing color of the sky in a city.

Our two-minute composition could be divided into the following sections: dawn (0:00) – sunrise – morning – noon (0:30) – afternoon – sunset – evening (1:00) – neon lights (1:20) – midnight (2:00) For each section we found an image online to get sample colors from. Since we had three lights, we aimed them at different heights of the wall, while also mixing the colors by giving them some overlap with each other.

For the neon light section, we picked colors from this image of a Japan city we found online. We drew our inspiration from the concept of “Cyberpunk”, which is a sub-genre of sci-fi that has inspired movies like Ghost in the Shell and Blade Runner 2049. Cyberpunk works usually feature a wide use of neon colors in city scenes.

Below is our composition.

Kinetic Light: DMX lights composition ——Eric Parren (Skye Gao)

Partner: Louis, Candy

After the in-class test of DMX light, we realized that compared to other led light, the span of DMX light is larger and thus is more likely to create a environmental effect. So we decided to imitate Aurora in nature. 

Since the Aurora we encountered before are some documentary videos online , and from the documentary videos/photos, we found the Aurora is usually in a green tone gradually change to other colors. So we found some images online as reference and took the colors from them, in this case, they are pink. blue, green, and yellow. 

The composition mainly consists of gradual fading and changing of colors. The color will first show as green, and add gradually adds on the color of blue, pink, and yellow. At first we tried to place some gauze in front of the lights to show the flow and texture of Aurora. However, we found out the outcome was not very natural: we need to wave the cloth by ourselves and get out shadow into the scene. 

So instead of using we decided to focus on the light and making the light flowing through programming. We approached it by set the appearing time for each color slightly different so that the visual can be more natural and creates the effect of lights moving around. We also found a background music to add on the effect.

The ultimate outcome is very satisfying, we really like the quite and relaxing feeling our composition created. We, however, need to consider the color for carefully as we got feedbacks like the pink in the light is a little bit distracting.

Kinetic Light: LED Assignments ——Eric Parren (Skye Gao)

LED Light Assignment 1: Light with Music

For this project, I wanted to sync color changes on the Analog RGB strip with music pieces. Instead of programmed the changes of colors to a settled music, I wanted composition can be applied to any music pieces. So I used a sound sensor to receive sound values and controlled color changes by setting ranges to the received values. Circuit is shown as below:

One main challenge I met was to set the range for sound signals. Since the sound sensor is very sensitive and can only identify the volume, the value it receives depends very much on the environment. Therefore, I need to change the coding each time I play the composition. As a consequence, the color displayed is very random and I can not control the speed precisely. Here is a demo for a random song test:

However, the outcome can be quite nice is the music is fast-tempoed. This is the demo for presentation:

The feedbacks I got from presentation were related to the issues I met during the process: The color change was too random and not precisely synced to the music. But I also got suggestion that, with processing, I can actually analyze the frequency of the music and sync it to the color change, which will make the composition more harmonious.  

LED Light Assignment 2: Music light show “Ambush from Ten Sides”

Partners: Candy, Louis

For this project, we made a 2-min composition using RGB LED Strip synchronized with music. The music pieces we chose was “Ambush from Ten Sides”, which is a classical piece of Chinese lute music about a battle between the Chu and Han armies, set in 202 BC. We took reference from an instrumental performance on youtube and edited the music by ourselves.  It consists of four chapters of the original composition: Ambush, Initial Battle, Final battle, and tight encirclement. The reference  from Youtube: 

The way color was displayed was inspired by one of our in-class assignment using the Fade-candy library, which processing will read the color pixels on images and shows them on led strip.

We used images online/dots we drew by ourselves, and let the led strip reveal the color on the image. It took some time to sync the image color to the music content. Image shown as below:

We later added a storyboard for the audience to better understand the cone ten of the music pieces. And this is the presentation demo in class:

Kinetic Light: DMX Light Assignment–Eric(Candy Bi)

Project: Aurora

Team members: Louis, Skye

Process: Unlike LED strips we use before, DMX is way bigger. Considering the fact that it could give a bigger range of light on the wall yet could only light up one color at one time, we decided to imitate Aurora in nature. I have only seem aurora online, so I feel really excited. We googled online and download a image of aurora and put it in AI to get the color index of it. We found that it is usually green accompanied by some sort of purple, yellow and blue. These color later became the color we used to code.

The project has stages: pure green fading in and out, green and blue, green, blue and purple, green, yellow and blue. We made the DMX light in the middle a little taller than the other two so that together they could create an effect of light moving around. Each color differs slightly in how bright it is and how fast it fades so that the light would not be too statistic but rather more organic. Initially, we were thinking about having the light mapping all over the room, yet found that way we might lose the part of two color mix together.

To match the visual part, we found a light music that also create an atmosphere of relaxing and pleasant.

Overall, we were happy with what we got for this project shows a possibility of a grand light show if we could have more DMX lights being controlled. We are really excited if we could change the entire room into a live aurora show. The experience of lying in the coach on 9th floor, watching the lights fading in and out with all the lights closed at night is an impressive and touching memory.
