Installation "A drawing pendulum"

[nomoreclevernameslef]

Love it! Could you give any example code? No one minds if it is rough, it just would be great to learn from the techniques...

[pvrellis]

The code is something like this (in pseudo-language):

loop { point pendulum_position=wii_tracker(­); point bitmap_position=translate_to_b­itmap_position(pendulum_positi­on); int pixel_value=myBitmap[bitmap_po­sition]; if (pixel_value==1) drip_ink();

}

[pvrellis]

where:

myBitmap is the (black&white) image to be "printed"

wii_tracker() is a function that tracks the pendulum's position (x,y)

translate_to_bitmap_position() is a function that translate the coordinates (pendulum to myBitmap)

drip_ink() is a function that drips ink

@nomoreclevernameslef

I'm happy you liked it!

[pvrellis]

I used an "electric spray gun", set to minimum nozzle setting, just enough to drop ink.

My other installation "Irrational pendulum" (please see video) works with a solenoid valve.

how do you eject the color? does it put down a pen, or open a valve, or start a pump?
