This instrument is a computer controlled acoustical angklung designed and build in 2000. In 2006 it has undergone a major upgrade of the entire hardware. The anklungs themselves are made of hardened brass and tuned to a western scale covering two octaves. The instrument can be played by standard MIDI commands. It is mounted on a heavy duty trolley

and can be taken on the road for street performances. However, it is not rain resistent and should be protected against moisture. On june 21th its builder wrote a tango for this instrument. This composition was called `KlungelTango` and is scored for in combination with a singer or a melodica. The computer program was written in and is interactive. The piece can be performed on the street by a single performer. This tango was premiered on monday 4th of july, the melody performed by Karin Defleyt and the tango danced by the author with his partner, Moniek Darge. It was recorded for RTBF-television. The instrument was made and designed to be a part of the project realized for `Web Strikes Back` at the occasion of the Tromp biannual, october 2000 in Eindhoven, the Netherlands. A first composition that became a part the the project is called `Klungels`. Both a version for the `Klung` as a simulator version using real samples recorded from `Klung` as well as a plain vanilla midi version is available as part for downloading from the Logos website. Work on this interactive software was also done by Kristof Lauwers. The musical range for this robot is: Detailed circuit of the PIC-boards themselves can be seen by clicking this link. Note that the solenoids we used have double windings, one winding for each direction of movement. Thus no return springs are mounted. The alternation of the...
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.....
