More Paper Circuit Control by Frederic Gerchambeau

Since the last time that i posted about Frederic Gerchambeau's paper circuit experiments he has already posted a few more videos further developing of this concept to his GruithuisenCityMan YouTube account.

In these videos he shows how a paper circuit, a simple sheet of paper with a conductive/capacitive substance, can be integrated into a modular system.

I will not publish all his videos here (you can always subscribe to his channel), but this one was interesting enough to share here...

Video: Wandering (paper circuit as a ribbon controller) by Frederic Gerchambeau

" Hello ! My name is Frederic Gerchambeau. 

I have made this movie and this music. The music has been made using a parper circuit and a Doepfer analog modular system.
The paper circuit has four outputs. One leads to the cutoff frequency of lowpass filter 1, another leads to the cutoff frequency of lowpass filter 2, a third one leads to the pitch CV control oscillator 1 and a fourth one leads to the pitch CV control oscillator 2. So, with a wire coming from a Doepfer A-183-2 offset, i can control these four parameters depending where the wire is on the paper circuit. The echo effect comes from a Make Noise Echophon. Enjoy !

Paper Circuit Controlling a Doepfer A-152 Sequencer by Frederic Gerchambeau

Frederic Gerchambeau uploads interesting analog/modular videos to his GruithuisenCityMan YouTube account very frequently.

This time he hasn't uploaded a musical piece, but just an interesting demo of an idea.

In the video he shows how a paper circuit, a simple sheet of paper with an unknown conductive/capacitive substance, can be integrated into a modular system.

Sadly Frederic's videos don't often come with a lot of information...

The idea is not new, but i haven't seen the use of it in combination with the A-152 Voltage Addressed Track&Hold / Analog Shift Register.

Earlier this year I posted about another project using a capacitive paint, you can find that HERE.
I assume the same Bare Conductive paint is used here, but i'm not sure...

Capacitive Paint Controller by Jimmy Hughes

From Jimmy Hughes' website:

" I have been playing with Bare Conductive paint since it came out a little more than a year ago.

It’s great stuff – a heavy acrylic paint that can be used as a resistor, touch sensor, paintable wire – and I keep coming up with new uses for it. 

 This idea stemmed from wanting to utilize my modular synth in more of an installation setting than a performance music setting.

I think of this as a sort of “sonic self-portrait.” 

 Two 10″x 10″ canvasses painted yellow with my hand prints painted in conductive paint. 

 A small piece of copper tape is attached to the back of each canvas and connected to Arduino. 

Code on the Arduino turns the canvases into capacitive sensors and sends two channels of 0-5V PWM voltage out through RC filters into the modular synthesizer. In short: touch the painting, send modulations to the synthesizer."
