Illuminated Shroom
An outdoor installation by Absolute Value of Noise, © 2011.
The Illuminated Shroom is a large tree fungus that, like it's cousin "Poison Mentor" has become savvy about science. It is inspired by the notion of wind-clocks and alternate scales of time. It perceives the wind as a variable force that blows during the daytime and goes quiet at night. Thus each day has a different length in wind time, and each night the shroom has an opportunity to stop and reflect on the day.
The shroom is a solar powered creature that monitors and records the wind during the daytime, and at night it uses its findings to create a pattern of light, played-back on amber LEDs. Connected to the Tik or Time Inventor's Kabinet project at OKNO in Brussels, the shroom also sends it's wind data to the Internet in the form of TiKs.

You can see the wind sensor (the 4 little prongs) just sticking over the top of the battery.

The batteries are hidden under the lower fronds.

In the studio at Twilight.
At Twilight the Shroom switches modes. It stops collecting wind data and starts to playback the day's wind information on the LEDs.
|
|
Strong winds during the day will cause all of the LEDs to be lit most of the time, and slow winds will trigger just one or two LEDs at a time.

|
|
The light pattern changes every two seconds.

The prototype wind clock sitting in the studio window.
At this point I'm just making sure that the solar panels provide enough power to charge the batteries and operate the wind sensor at the same time.

The brain has been programmed and wind clock measurements can now be sent out to the Internet. The programming runs on a PIC16F88 microcontroller. The artists in Belgium have designed a server that recieves what they call "Tik"s. One Tik is approximately the amount of wind it takes to drive one swing of a pendulum style wind clock.

The batteries charge quickly. In 3 or 4 hours they have enough juice to run the LEDs all night.

Hanging on the side of the mason bee mansion at the Twilight Tea Party. At Means of Production garden, 6th and St. Catherines in Vancouver.
This was an event produced by
MOPARRC and
Second Site Collective. The tea party started at 8 pm (when the sun was out) and ended at 10:30 pm (after dark).

September 6 - 11, 2011.
Six days of radio programming scheduled by wind time.
This was an event produced by
COL-ME (Bratislava, Slovakia). The average wind time was calculated from the wind time of several TiK clocks, and this time measure was used to schedule radio programs and streams.

As part of this event I created the
"21st Century Universal Time Signal" live audio stream. This is a generative audio piece driven by the TiKs of the Illuminated Shroom. Here in Vancouver the fierce blowing of wind is often accompanied by rain. So I made a water clock and recorded the sounds of its droplets. When the wind clock Tiks, a splatter of droplets is broadcast on the 21stC-UTS. The signal then degrades over time until another TiK passes through the system. At night, when the Illuminated Shroom stops monitoring the wind, the UTS degrades further into an eerie night-time ambient soundtrack.
I made a short recording of the stream, starting about 5 minutes before twilight (when the piece shifts into night-time). You can download it here:

"I was playing the stream on a bright sunny day when I noticed a woman outside. She kept stopping and looking up and then I realized that she was trying to find the strange cascade of water droplets that she could hear once every 20 to 30 seconds emanating from my upstairs window." - August 20, 2011

Now that the winter is approaching, the Shroom is safely stored inside, and I have replaced it with a solo wind sensor hanging out the window under the eves.
This is the Shroom circuit reduced to bread-board with a photo-cell in place of the solar cells (to tell night from day).
