White Light is an interactive sound and light installation. It is part sculpture, part musical instrument and part social exercise. White Light invites viewers to become part of a complex sound and light display by manipulating the controls on one of 3 control podiums spaced evenly around a glowing orb. As a viewer approaches a podium it begins em

itting an audio drone and the ball in the center illuminates. The viewer may manipulate a series of controls on the podium which alter the characteristics of the audio signal and light display. The brightness of the light is relative to the phase alignment of the two oscillators. When two oscillators are slightly detuned it creates a cyclically modulating phase alignment. This manifests as a modulating volume or in the case of the lights, a modulating brightness. The rate of the drone is relative to the detuning of the oscillators. The closer they are together, the slower the drone or pulse. Guitarists use this trick when tuning their strings. The same drone signal is used to generate the sound as well as the light. Each of the three podiums generates a different color in the sphere. Red, green and blue. The name White Light refers to the light generated by activating all three podiums at once, thus mixing red, green and blue light making white. White light only occurs when all three colors are at equal intensity. Due to the nature of the light modulation control, each color is constantly pulsing in and out. This means that the total color of the sphere modulates as each of the three colors combine at constantly changing intensities. The result is unpredictable and ever changing without ever being random. It`s similar to watching a flickering flame, simple but hypnotic. The second level of interaction is as a group....
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
