Final idea

The rolling music box at the middle to generate sound with light goes through the paper. Put several music boxes on the floor that reacts with the music generated.

However i am not sure if i can made the VU meter

music making (FL studio)

i would like to make my own piece of music instead of using free resource SCM provided.
I use FL studio to make my very own piece of sound and clips.

FL studio is perfect for my project.

Design of the VU meter

A device that put on the floor that have 10 level and i will put LEDs inside it

2010年11月20日星期六

i want to make a device that would measure the volume level. So i decided to make a VU meter and show the result in form of light. MY idea is the music box generate music then the music trigger the LED devices.

Do some rearch about it then i find a chip can do the effect i want.

this is the schemic for my project

making of LED music box interact with music part5

I think glass is the best then I bought them

Foam to fix the LEDs into place

Final result:

making of LED music box interact with music part4

Tried different material to be to be the container

making of LED music box interact with music part3

I start to work out a better brighter circuit and change it to a parallel circuit and link up more LEDs.

I tried 4 leds first and found that it is not bright enough and start to change the whole wiring.

Putting 2 LEDs together as a unit and make the wires more tidy.

close up

It works well

After so much soldering my brand new soldering iron change color…..wonder why it became blue

2010年10月12日星期二

study about parallel circuit

after i sucessfully made the device i find out that if i want 4 led then i will need 8 AA battery. The problem is 4 leds are not enougth for my project . So i tried to find ways to add more leds.

After reading many knowledge about electronic circuit i finally figure out a way.

Series and parallel circuits

http://en.wikipedia.org/wiki/Parallel_circuit

just make the circuit parallel then i can use 3V (ie 2 AA battery) Then i can light up as many LED as i want.

Then i start to change the circuit diagram.

making of LED music box interact with music part2

Tried at least 6 old 3.5mm audio jacks finally get one which works

later i figure out that they wont work because i didn't solder them together.

actually i blink with the music i am playing!

Then start serious soldering (This is the first time soldering ever in my life)

not bad right?

After hours of trying the device finally works

Nice effect in complete darkness

making of LED music box interact with music

Trying to connect 3.5mm audio jack with Tip31

start blowing LEDsss cause of wrong resistors

Finally get the LEDs lit without burning them but still not working with Tip31

processing liabrary

music library for processing

Minim

Minim is an audio library that uses the JavaSound API, a bit of Tritonus, and Javazoom’s MP3SPI to provide an easy to use audio library for people developing in the Processing environment. The philosophy behind the API is to make integrating audio into your sketches as simple as possible while still providing a reasonable amount of flexibility for more advanced users. There are no callbacks and you do not ever need to directly manipulate sample arrays, all of the dirty work is handled for you. The download comes in two flavors: (1) just the jar files needed to use Minim and (2) a full distribution that includes the javadocs, examples, and source code. Minim is licensed under the GNU Lesser General Public License (LGPL), a copy of which is included with both distributions. Users of Minim 1.1 should peruse the Javadocs to see what’s changed (hint: not much has changed, but there are a couple of nice new things).

programming language change : processing

finally i decide to use processing to make the music box light detection
it allows me to output as many sounds as i like.
and it is free to use easy to extend and use one different pc.

Music box program problem

still working on flash action script .
But found a problem , it can only support 4 music out put at the same time. My project need a lot more output for my project. so i will need to change my programming language.

idea

I like starry night with billons of stars. Hong Kong is such a busy city. Light pollution is very serious. Light is everywhere at night. Even when I go fishing surrounded with mountains I can’t see many stars. I know that I can never see a starry sky at night in Hong Kong. So I decide to create one by myself.

I want to have a starry night. Then I think that will be great to make one with music. That inspires me to create a music box that uses light to emit sound that creates also a starry sky effect in a dark room.

The basic structure is a roll with holes. Inside the roll there will be LEDs .Then lights will go through the holes. When we roll it (there will be a handle) lights come through the holes will make an effect of starry night in a completely dark room.

Under the table there will be a web camera linked to a laptop. The web will have color detection that only detect black and white. When it detects white (there is light) it will emit the note of that position. (This will be done by action script).

Things brought

to fininsh the circuit i need lots of tools

tool needed:
1. solder
2. soldering iron
3. wires
4. Tip31a or c
5. place mat
6. resistor
7. 12v input (i am thinking of 12V battery case)

so i go to shum shui po and Taobao for them

2010年7月4日星期日

The LED circuit i will make

This is a circuit that need a input of 12v , 4 leds, wires, a chip TIP31a and a audio jack.

this circuit allow the LEDs blink with the audio input

LED interactive with music

i go through lots of circuit forum for my project

http://forum.allaboutcircuits.com/

http://www.electro-tech-online.com/

http://www.electro-tech-online.com/

i raise some of the questions and get some help form ppl online .(i will credit them in my report)
i never study physics and these circuit stuff so the whole project is very challenging

finally i made up a circuit suit my project and i think i am able to finish it.
i will post the circuit diagram later
