R. Ghazala The glass in my workshop window is 70 years old. Its thickness varies, and the world outside passes by in fluid, undulating waves. In the cracks of this glass, where a forgotten autumn's chore may have left its mark, can be seen all the colors of the rainbow, refracted splendidly for anyone given to close inspection. The plans, today, upon which the fairies dance are those of the circuit-bent Casio SK-1. Où vous procurez-vous vos composants - – Plate-forme pour l'électronique et les microcontrôleurs.url. Jacoti, pionnier en matière de technologies auditives, vient de lancer Jacoti Lola, pour la transmission audio sans fil dans des contextes auditifs brouillés.

Les salles de classe, les salles de réunions, les auditoriums et même les voitures peuvent engendrer des situations auditives complexes. Dans ces environnements, Lola améliore et diffuse un audio avec une qualité équivalente à celle d'un CD. Jacoti avait déjà lancé le logiciel auditif autonome ListenApp. Lola est donc une technologie logicielle pour la diffusion audio par les réseaux sans fil standard, bidirectionnelle, à faible latence. Pour la mise en place d'une session avec Lola, il suffit que le locuteur et l'auditeur activent l'application sur leur téléphone tactile. Qu’y-a-t il de plus important pour un auditoire que de comprendre parfaitement la personne qui parle ou d’apprécier pleinement la musique ?

Its a website by Frans Samshuijzen with detailed descriptions of some mods that he did to a set of Casio SK-1 keyboards appropriately titled: “Casio Twins“. The mods include a full pitch mod with the use of a TI 74LS624 voltage controlled oscillator. It is also worth noting that a 555 timer circuit would theoretically do the same thing, except that the max frequency of a 555 is about 2Mhz and with the LS624 chip the schematics indicate a range of between 1.5 and 10Mhz with a max of 20Mhz.

The downside however is the fact that the LS624 is far more expensive, $2.55 a pop. Still worth every penny considering that the Casio will provide for a full 3 Octave mind melting sound experience, along with longer and grainier recording times.

The 4017 IC is CMOS, and therefore sensitive to static electricity! Any single-pole, single-throw switch is adequate. A household light switch will work fine, and is readily available at any hardware store. Gallery.url. Ana-R.url. Synth schematics. Classic Schematics.url.

They include the owner’s guides for SK-1, SK-5, SK-8, and DM-100. The SK-1 service manual aka the Bible is also there. Very neat to look at, although I am a little puzzled about the addition of the Tablebeast Modification pages in the PDFs. At this point they seem to contain nothing. At any rate, grab them while you can. Elliott Sound Products - The Audio Pages (Main Index).url. DIY » Schematics son aléatoire.url. Effects Heaven Effect Schematics - .url.

Custom sample names and lengths! YES!! I have yet to test it, but it looks like you can import your own samples and change the names and lengths as well! Audio projects, circuits and audio kits. Muting Transistor Attenuator Circuits and the 2SC2878 by Jim Keith | Among semiconductors, the muting transistor and its audio application is perhaps the most obscure and poorly understood of all. There is extremely little information on this subject available on the internet and what is available is sketchy. This discussion is an attempt to tie the pieces together and to add some insight –I... Simple Mixer Schematics. Simple Mixer Schematics PREAMBLE: I've been cooking audio circuits for so long now I no-longer need a recipe. A lot of the theory I have forgotten over the years because I've just gotten to know the circuits by instinct.

But this should serve as something of a guide to designing mixers from scratch. The idea: Most people reading this would be well aware of what a mixer is used for but I'll reiterate here.


Selected Schematics. Caveats Permission is granted to link to the schematics on this page however I do not extend permission to place copies of the schematics stored on this site on other sites. In other words, you can link, but don't download and place them on your server and show them as yours. Before you go wild downloading these links and buying parts for the schematics listed below, there are a few things you should know. If you don't feel like reading yourself or helping yourself, you shouldn't pursue building your own boxes. Réalisations Spoutnick Studio. Realisation d'un Circuit Imprimé de A à Z. Simple Passive Tone-Control.

I have built up quite a collection of headphone amps and now venturing into higher voltage/wattage amps. My workbench/home office now has a variety of sources and amps, but one DIY item that was missing was an EQ of some sort. I have a few preamps, but I really did not want to add any more gain and noise to an already congested system. Bases - Realisation circuit imprime.

Datasheet. Circuits. Antonelli project. Electronic. Arduino Site. Bastien Lartigue. Synthesizer.url. writes: I just finished building a frequency synthesizer with the MAX038 waveform generator from MAXIM, you can download the datasheet here: MAX038 High-Frequency Waveform Generator. My circuit is a copy of the high frequency waveform generator in the datasheet, with a 16F877 PIC controlling the device.

Below you can see some pictures of my design (click on the picture to enlarge it):The main PCB, with MAX038 high frequency waveform generator, powersupply and 16F877 PIC controlling the frequency synthesizer. I have detected a small error in the PCB, pin 11 and 12 on the MAX038 IC has to be connected to ground. Visual Analyser details. Detailed Features about: VA main form (version 8.x.x) (1) - Oscilloscope Dual channel Bandwith : depends from your soundcard (typical 20 Khz) up to 96 Khz (192 Khz sampling frequency) Resolution from 8 bit (S/N 46 dB) up to 24 bit (S/N >120 dB) Time division adjust according the sampling frequency and sample resolution Trigger (positive/negative slope) independent for both channels Complete software D/A of digital samples : the Nyquist theorem allows reconstructing exactly the input signal Utilities for quick frequency determination (hold left mouse button down and move mouse to get frequency/amplitude) Y-axis in Volt and percent full scale Auto calibration of scope (and spectrum) in volts (need an input signal of known amplitude)
