The Jigging Being: Traditional and Digital with Guillaume Coulombe

I'm Guillaume Coulombe, entrepreneur, artist and instigator,

although this was a team effort

for the Violon de Jos' scenography kit.

Here we have the Jigging Being and its electronic skirt.

We also have the MIDI foot-tapping board

and the visual interpretation of the MIDI signal

that we're using to develop other creative applications.

Fab Lab Digital Manufacturing Lab

I'm involved in the world of fab labs,

which are spaces for creativity and manufacturing

that are equipped with computer numerically controlled machines.

We were to curious to see

what a fab lab-designed concert could look like.

We wanted to explore what could be done with podorythmie

if we captured the signal.

We knew that Alain Lamontagne

had already done MIDI foot tapping,

so we wanted to explore the visual aspect,

and also connect the board to the Jigging Being

so that it's activated by the foot taps.

How It Works

To activate movement,

we equipped it with two solenoid motors in the back.

We created a leverage effect

to pull the legs up from behind.

Under the chair, there's a card

that reads the electrical resistance

created when the pad is pushed.

It's then converted to a USB signal that's sent to the computer

to create all kinds of different light projections.

Besides that, there's another wire

that's connected to a power supply management card

that sends 50 volts to each of the motors

each time the foot produces a tap command.

Technologies Employed

There are all kinds of technologies in a fab lab.

We used 3D printing to make the shoes.

The skirt was made in a media lab

called Milieux, at Concordia University.

We made a digital skirt

that has a digital controller and a heat sensor

that senses the motors' heat

and sends the light signal.

To make the power controllers on the copper wiring board,

we used a CNC milling machine.

We made a computer-aided design

of where we wanted the electricity to pass through,

and then we removed those parts from the copper

using the CNC milling machine, which is very precise.

It's the same thing with the board.

It's made with a CNC milling machine,

based on a drawing that's shared on the Violon de Jos site,

and that outlines how to make both the pads and the board.

We made a little holder with the 3D printer to prop up the pads.

We developed a visual interface,

so you can navigate between the different visual projection modes.

And there's also an improvisational mode,

where you're given a command on how to play,

which influences the concert,

and puts you in an improvisational mode.

So when I tap twice on the pad in the upper left,

it displays one of the words saved in the program.

It might be the name of a tune,

like "Hommage au père Fusion",

or a command like "Play an asymmetrical tune."

We made the Jigging Being with open source code,

so that it could become a collaborative project.

We want to send it to schools,

so that physics teachers can improve on it with their students.

They'll be encouraged to redesign the knees,

or to redesign shoes that sound better.

The experience surrounding this project is collaborative,

and we believe that it could lead to a Jigging Being

that no longer requires a frame; that will be able to jig on its own.
