The Production Process Documentation.
Here I have documented the process I went through of developing and building an interactive LED sound piece. I hope you find it interesting. If you have any questions, tips, or praise let me know on my feedback page.

Workbench.
These are the tools I used to actually make the project. Out of the picture are the iCube and Midi converter. |
 |
iCube Interface .
I had to make this in order to trigger the LED sequences from software. Simply I could have used a relay to trigger the switch on the sequence, but the ones I had access to would have blown the iCube. So I had to use LED's to trigger a light dependant resistor, hooked up to a transistor, to throw the switch instead. |
 |
1 of 8 LED Sequence boards.
I managed to get 8 LED sequence circuits out of fancy birthday cards. I butchered these to create one LED sequence. |
 |
Making it work.
As I mentioned before, I couldn't use a relay to trigger the circuit, so I had to use the LED's coming from the iCube. This meant I had to use a light dependant resistor, with a transistor instead.
I then put the light dependant resistors next to the LED's from the iCube interface, which triggered the circuit. |
 |
Wiring in the LED sequences .
This bit was really hard, so many wires, so many LEDS - 96 to be exact! |
 |
Speaker Box .
The piece had a microphone and LED's, so it was interactive, but I wanted to make it more so. I made a little speaker box to put inside, so the piece has the capability to speak and interact back! |
 |
The Umbilicus.
In order to get the iCube to speak to the LED's, I needed some serious wires. 8 Sequences, requiring 2 cables each, plus 2 for the speaker box, and about 2-3 meters of each! |
 |
Nearly Finished.
I am getting there! Finally. |
 |
Setting it all up.
There is my powerbook, hooked into the midi controller, coupled onto the iCube. A nightmare to set up, but well worth it. The black box is the iCube. |
 |
Setting it all up 2.
Now the computer was set up I needed somewhere to hang the piece so it was easy to interact with. |
 |
Silhouette.
With the light behind the piece, you can see all the circuit boards and wires. |
 |
