RESONANCE CUBE
RESONANCE
CUBE
Inspired from the instructables webite, this resonance cube was created as an extension to exploratory Singapore soundscape visualization project. The cube visualizes sound by means of multiplexing through the series of the LEDs anodes and cathodes. Sound that have been visualized is displayed in the front section and is then sequentially passed to the back of the rows through a series of arrays stored in arduino. It proves that visualizations of sound in spaces is not restricted to either screen or print but also through being electronically tangible.

LED A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

SCHEMATICS Before starting, it is important to test whether if all the LEDs are working. This project requires a total of 64 LEDs. The schematics shows how the cube is being constructed. A wood block was drilled 4 by 4 to be used as a template so that the LED can be aligned nicely and straight. Each hole is 3mm in diameter and a gap of 1.5cm between each hole. The top layer will be the layer to be constructed first. The cathodes are soldered next to each other by means of bending the cathodes. A steel wire is used to cover the end row to make the LED more robust. The 64 LEDs are soldered in division of 16, with 4 layers. Each of the 4 layers is soldered with their cathodes (-) contacting each other.

ANODES
In order to be able to connect the anode pins to the higher layers, anodes are bend slightly. This allow the anodes from the bottom layer to touch the anode above it easily. The anodes are connected through the rows.

RESISTOR
Before inserting the cube and resistor to the board, the perfboard is sprayed black. 16 resistors are inserted and soldered on the back of the perfboard. The cube is then inserted and soldered. Wires are used to connect the columns to the resistor before going to the pins of Arduino
SOLDERED ANODES
SOLDERED RESISTOR
After soldering the anodes to the resistor, the wire is joint to the perfboard. These technique of circuit is called multiplexing. To on a certain LED, the chosen row and column can be activated, while the rest are disabled.
