The toothbrush that sings “l’Internationale”

How does one to go to work motivated in the morning? The collective of hackers Dardex found the solution: an electric toothbrush that sings “l’Internationale”. Tutorial

To all those who have once had the strange feeling of hearing a tune in the humming of their electric toothbrush, or even another voice coming out of their own mouth on the limit of paranormal, Quentin Destieu from the collective Dardex proposes to return to materialistic pragmatism and get off to work to a good start in the morning. Your toothbrush will play the communist hymn and your mouth will serve as a listening room as if the Russian military choir had suddenly started the revolution in your buccal microbiome. Generously, Quentin was nice enough to detail his toothbrush hack, the phenomenal success of which has been promised for the centenary of the Bolshevist revolution next year.

“The people’s toothbrush”, Quentin Destieu, demo:

The duo of Dardex artists, composed of Quentin Destieu and Sylvain Huguet, is also behind the Gamerz Lab and the eponym festival  of Aix-en-Provence. This isn’t their first hack. They have already put forward the computer that smokes the narghile, the goldfish that moves around in a chair for the disabled or still Neolithic tools made from recasting of electronic waste. These artists from Aix-en-Provence do not lack humor to question our relation to machines.

This time round, Dardex commits itself: the communist propaganda strikes the proletarian close to his body in the morning after waking up. The sound signal of “l’Internationale” is transmitted to an electric toothbrush and interpreted by the rotation speed of its motor.

Quentin Destieu chose the title Volk Zabnbürste (Homage to Karl Marx) and presents his communist toothbrush very seriously as follows:

“Surfing on the success of different connected objects, the enhanced toothbrush allows you to play the communist hymn “l’Internationale” via vibrations by going directly through the root of the individual’s teeth.”

In order to prepare yourself for a proletarian dental awakening, follow the instructions bellow.


– An electric toothbrush;
– An audio player (such as an mp3 or a telephone);
– 1 male/male mini-jack cable;
– A pre-amplified speaker (such as a computer loud speaker).


– Open the battery compartment of the brush:

– Pierce a hole in the bottom cap;
– Cut a mini-jack cable in two and strip one end;
– Run the mini-jack cable through the previously pierced hole;
– Weld the mini-jack cable to the terminal posts of the battery;

At this stage, do not forget to leave space for the batteries (and replace them). © Dardex

– Dismantle an amplified speaker of a computer, retrieve the amplifier;
– Connect the toothbrush and the amplifier with the mini-jack.

– Connect the amplifier to the sound source (where “l’Internationale” will have previously been stored…)
– Brush your teeth for 3mn26s (the duration of “l’Internationale”)…
