Chaodependant

I'm going to use this post to collect photos and media from Kinetica 2010. To start with, here's Parag's Flickr set: http://www.flickr.com/photos/pkmital/sets/72157623393186086/

ChaoDependant feet

Thanks to the kindness of TINT, we're exhibiting both Chaodependant (by me, Owen Green and Agelos Papdakis) and Memory (by Parag Mital and Agelos Papadakis) at the Kinetica art fair in London.

The last times Chaodependant go shown, it worked great, but the carpet base it was on looked awful. So, for taking it down to Kinetica we decided to put it on a more professional platform. Apart from aesthetics, we also wanted to address the problem that the pendulum gets further away from the pods towards the end of it's swing, and hence they have less effect on the movement.

ChaoDependant installed Final days of testing, and doesn't everything all seem to go wrong at the end!

It turned out that when the high power LEDs are running, they drag the supply voltage down by about 0.2V. Which would normally be OK, but the Hall sensors are giving voltages in the mV range, so the changing supply voltage gives a bigger signal than the actual magnetic signal.

Damn.

We tried a bunch of things, mostly involving big capacitors, but nothing worked really well.

It's really exciting when things start to come together... Last night me and Owen got two pods working: disturbing the pendulum bob, sensing it, and communicating with Max/MSP via the Arduino.

Each of the pods in chaodependant has:

• a Hall Effect sensor
• a high power LED.
• some magnets
