Here we show a little Theremin module which plugs onto a Arduino Board that gives out the tune to a speaker or puts out the tune as control signal like MIDI, Servo etc. We were using this device not only as a musical instrument, various kinds of proximity sensors, pointing devices or as interface in combination with Processing, Max or Pd have been build with this technique. How it Works The Theremin Module itself is as little LC type Radio frequency oscillator which generates a radio wave and gives out the frequency signal to the Arduino board. An Antenna connected to the LC resonator provides the Theremin effect when a person or some conductive material is placed next to the antenna. Video The Oscillator If you have a look at the Oscillator schematic you see the components L1 and C1 that are forming a resonator responsible for the oscillator frequency of about 4.1 Mhz. Care must be taken in the choice of the parts L1 and C1. TTL LC-type Oscillator schematic Oscillator Breadboard Layout

Beryann : Musique avec Arduino: un Theremin... Rafael Lozano-Hemmer - Project "Under Scan" Relational Architecture 11 Under Scan is an interactive video art installation for public space. In the work, passers-by are detected by a computerized tracking system, which activates video-portraits projected within their shadow. Over one thousand video-portraits of volunteers were taken in Derby, Leicester, Lincoln, Northampton and Nottingham by a team of local filmmakers. Every 7 minutes the entire project stops and resets. The piece was inspired by representation en abîme, where the portrayed make eye-contact with the viewer, - as found in works by Jan Van Eyck, Parmigianino, Velázquez or Leon Golub.

4 Ways to Make a Theremin Edit Article Building the CaseBuilding the Pitch ControlBuilding the Volume ControlFinishing the Theremin Edited by Ir1337, Michael Jackson, J̷̀K̀̀͟͝L̷̨͢͏1̶̛̀͞2̡̢3̡͏̸͘͢4҉̶̷, Gloster flyer and 5 others A Theremin is a musical instrument that's played by manipulating electromagnetic fields generated by antennae. Ad Steps Method 1 of 4: Building the Case 1Find or construct a box to house the Theremin's internal circuitry. 2Install the antennae.A monopole antenna (pitch antenna)is attached to the top of the box on the right side if you are right-handed and to the left side if you're left-handed. Method 2 of 4: Building the Pitch Control 1Create the pitch control with a variable oscillator and a reference oscillator. 2Feed the output of each oscillator into a mixer. Method 3 of 4: Building the Volume Control 1Connect a variable oscillator to the volume antenna. 3Route the outputs of the mixer and the volume resonant circuit into a voltage controlled amplifier. Method 4 of 4: Finishing the Theremin

Arduino Theremin When I got my Arduino protoshield from sparkfun, I wanted to make something cool with it. And since I had seen a few Theremin projects before, and already thought about making some, I finally made one, using the Parallax PING sonar sensor. Here are some informations about how I made it. You can see all the pictures here. First, the schematics: Here's the commented code for the Arduino: And that's about it!

Un Theremin à simple à construire, et qui fontionne ! salut, je ne suis pas électronicien et j'ai réussi ce shéma du premier coup, si tu sais souder, il suffit de souder les composants dans le sens indiqué et ça marche... Le thérémine, theremine, theremin ou thereminvox est un des plus anciens instruments de musique électronique, inventé en 1919 par le russe Lev Sergeïevitch Termen (connu sous le nom de Léon Theremin). Composé d’un boîtier électronique équipé de deux antennes, le thérémine a la particularité de produire de la musique sans aucun contact physique de l’instrumentiste. Dans sa version la plus répandue, on contrôle la hauteur de la note de la main droite, en faisant varier sa distance par rapport à l’antenne verticale. Je l'ai essayé hier sur mon Jcm900 avec un delay analogique et de la la fuzz, c'est hallucinant!!! Comme le niveau de sortie est plus élevé, l'ajout d'un pot. de volume en sortie peut être utile, si on l'utilise en alternance avec une guitare... Nowhereman

LES RESISTANCES Composants électriques, électroniques et modélisme ferroviaire, cliquez ci-dessus Comme nous l’avons vu précédemment, la résistance est la propriété qu’ont certains corps de s’opposer plus ou moins au passage du courant. Son unité est l’Ohm, lettre grecque Oméga La résistance est un composant dit passif, elle n'est pas polarisée (sens de branchement), elle est caractérisée par : Sa valeur , sa tolérance et sa puissance . Sa valeur peut être fixe ou variable. La tolérance de précision est : 0,1 % , 1%, 5%, 10%, 20% et indéfini. Leurs puissances varient de : 1/8 de Watt à plusieurs dizaines de Watts. Son rôle est de limiter le courant dans une partie de circuit. Résistances à couches ou au carbone Fixes, elles sont utilisées surtout en électronique, elles sont d’une puissance inférieure à 5W, leurs valeurs sont normalisées (séries) et inscrites sous forme de code, (voir tableau en dessous). Potentiomètres, résistances variables et trimmers Résistances de puissance Résistances variables spéciales
