Shadow effects

Hello Leds!

Using TLC5940 with a power supply (12v transformer+ LM7805), and, 70 LEDs

The simulation of the lighting effect

viola — Mon, 29 Sep 2008 18:54:53 +0000

These two weeks, I have been focusing on creating the lighting effects for Resonant Wave. I use twenty six LEDs. Each of them represents a key on a computer keyboard. The Texas Instrument 4950 allows me to increase output pins from the Arduino board. I will study how to use a power supply for this in the following week, since my flower-like sculptures have hundreds of LEDs

The lighting effects include four steps. In the beginning, a light will brighten up far from the dancer’s position. It attracts her to come close to it. The according to the dancer’s location, a bright light will start to fallow her. After a while, groups of lights will follow her movements. At the end, she will create a light pattern according to her trail. Also, the brightness of the light is according to the sound she makes.

I used MaxMsp to control the time, the computer keyboard, and sound analysis. I used Arduino to control the light. And use Seiral.read to make Maxmsp and Ardino able to communicate with each other.

Hello, the prototype of the bracelet!!

“Little by little!!” My flamenco teacher always says this to me. This is principle can be used in almost everything.

1) This is first step. How to use an audio amplifier to send a signal??? I used LM386, a low voltage power amplifier. Thanks Liubo!

2) After making sure everthing was ok, I soldered the circuit on a board.:) I learned during my internship. Thanks Ayah!

3) I did a little more programming testing with Arduino. Making sure that the lighting effect will be as I expected!

4) Then I used the same trick that I worte about it before. Tada!! Yes, the wire wrap tool and wrap to connect the LEDs with the cute Lily Pad. (Lily Pad! What a good invetion!!)

5) Almost there, but how can I power it? I used the DL2032 3v button battery in the beginning. However, sadly the current is not strong enough. After testing with several kinds of batteries, PANASONIC CR2450 is the winner!!

6) haha… It is sitll not the end but today I will teach everyone a saying, which comes from Zhou Dunyi, a philosopher of the Song Dynasty of China. In his famous articl, LOVE LOTUS SAYING, he said “.” It describes why the lotus is so beautiful. The reason is that although the lotus was grown in silt, it is not impure but elegant. This is like the story of my desk and my flower-like bracelet.

If you cannot upload the programming to Lily Pad, …

Sometimes a very simple thing can make people crazy. Last night I suffered this kind of pain. I swear that I followed the instruction from Leah Buechley’s website.

” Press the reset switch on your LilyPad then Quickly click on the Upload button in the software.” (I also test my ATmega 168 Arduino board with the same process and it worked.) The only thing I didn’t do was: “See http://www.arduino.cc/en/Guide/Troubleshooing#upload”

This morning I am as obstinate as usual and decide to give my pad the last try. This is what I read and it help: “However, on some computers, you may need to press the reset button on the board after you hit the upload button in the Arduino environment. Try different intervals of time between the two, up to 10 seconds or more.

“

Yay!! Finally, I can start to do something I really like. Making accessories!!

When I had a chance to perform with my friends, I always enjoyed making us pretty!!

This is my last performance in Taiwan.

Tada!! I made butterfly necklaces.

Now, I plan to make an interactive bracelet for my Resonant Wave performance.

Coming soon: the bracelet!!

From 0 to 150

Yes, I know simple is good. However, my complex brain always bring me to another direction. The photo was taken on Feb 14th. At the time, my ceiling was kind of empty.

After making flower-like sculptures the whole summer time.

Tada!! There are at least 150 flower-like pieces on the ceiling now.

It’s not the end. There will be LEDs inside.

If you don’t like Solder…

viola — Mon, 18 Aug 2008 08:18:58 +0000

	There are a lot of LEDs. What if you don’t like to solder them, but you must use all of them???
Don’t worry my teacher, Peter teaches me a very good way!!
	You will need pliers, a knife, a manual wire wrap tool, a bundle of wire wrap, heat gun (image from left to right), and heat shrink tubing. I really like my heat gun. It’s very handy. It’s made by PRO-IRODA INDUSTRIES, INC and the model number is MJ-600.
	First, cut a length of wire and put it into the middle of the blue wire wrap tool. You need to use your right thumb and press down the wire, which comes out from the hole. Then you can either use your left hand, or use pliers to pull out the wire.
	After you strip the wire, you then insert it into the bottom of the tool. There is a very small hole near the edge.
	There is a bigger hole in the bottom of the tool where you can insert one lead pin. Now, it twisting time!! Hold your LED and turn the tool clockwise 8-10 times. Your LED and wire will have a very strong connection.
For more info, please see HOW to WIRE-WRAP
	Of course, it will be great to use heart shrink. How many have I made now? It’s around 250!!!

Rotating Effect Control of Resonant Wave I

The Motor and Light Connector

My floor will control the rotating effect of my ceiling sculpture. However, before designing my pad, how I can make my light rotate without twisting its wires is a big problem. After discussing with my cousin, a professional machine designer,�PC_Wang , he designed the motor and light connector for me. Itconsists of two bearings, carbon brush, and a gear motor. It allows my LED sculpture to rotate�without the problems of twisting wires. The image below is sample.

After solving the crucial problem, I am working on my floor pad. The principle of how my floor pad works is pretty similar to the DDR (Dancing Dace Revolution) dancing pad. There will be a form between tow conductor layers. There are several holes on the very thin form. When people step on it, the conducting part will influence the result on the screen. The following images showsa DDR dancing pad which is taken apart.

Based on the same principle, I will make a floor pad which has the same function. It will allow the dancer to control the rotating effects of my sculptures. The flowing videos shows my teacher and I testing the floor pad.

In the video, different parts of the pad can control the different lights on the screen
