The audio is straight from a drum machine, triggering the video in real time which is done in Processing; this initial draft shows that this is just the tip of the iceberg for what’s possible . . .

Although I didn’t learn anything new technology-wise, I was very pleased to learn about his great series of techno podcasts.

This is the third piece in my “electric window” series, which began in December of 2007 when I stuffed a small pre-made frame with EL wire and a decorative acrylic panel as an entry to Gallery 101’s annual fundraiser / art auction, 101 Frames.

The year after, I made another EL wire based piece, and animated the wire; this year I will probably go with a smaller version of “electric window (iii)”. Here’s a shot of the insides:

This piece was originally the display portion of a weather-responsive work that draws patterns based on wind speed and direction data — as detected from an external weather meter — received wirelessly by the FM receiver board on the upper right:

Unfortunately the wireless link was giving me trouble, so the wind-based project was put on hold, but the remainder of the circuit (an Arduino-controlled pair of Sure Electronics LED display boards) made for a perfect addition to my exhibition with the Conjunction Collective.

Thanks to westfw’s library, gaining control of the LED displays with the Arduino was fairly straightforward. I found the Arduino’s on-board voltage regulator got pretty hot while running two LED displays, so I made a mini-shield with an external regulator to supply 5V to the Arudino and the LED displays:

Not the prettiest or neatest, but functional . . .

With some slight modifications to the original weather project code, I had a “simulated” drawing program using random direction and length variables:

Next I wrote a few more drawing routines for vertical lines and boxes; I tried horizontal lines as well, but didn’t like the look so much.

I’m anxious to get this piece working with the wind instrumentation again, and for this year’s 101 Frames I’m hoping to make a smaller version of an LED-based “electric window” with an IR proximity sensor so users can interact with the display patterns.

In the meantime, here’s a vid. of what I have so far, as shown at the Conjuction Collective show in Toronto this fall:

Similar to the video from my previous entry, I recorded the audio for this video straight from my drum machine into the video editor. While I’m not as pleased with the results musically, these exercises of spontaneously scoring lighting footage with coordinated beats/atmosphere are proving to be “studies” for future works involving light-responsive sound generating means coupled with sound-reactive lights.

This piece has a colourful history

The original, static fixture shown above was built for Cube Gallery’s 2008 exhibtion, Homage, which asked participating artists to create an homage to an important influence on their art.

I chose to make a wall-mounted rendition of Dan Flavin’s fluorescent installation, “untitled (in honor of Harold Joachim)”:

For the Conjunction Collective show this fall, I decided to animated the piece . . .

I had an older, unfinished light work on the bench that I’ve slowly been pecking at for parts, based around a PIC-controlled relay board — with a little reprogramming, I’d have a quick update for the Flavin homage without having to build any new hardware.

First order of business was to make sure the old control board was still working, so I set to work with the cursed alligator clip connections:

I say cursed because I find it all too easy to short circuit something while working with the clips, but the ease and speed with which you can get components talking with one other is too tempting to pass up.

This is a common sight on my bench while I’m experimenting, and I’m sure I’m not alone on this one.

Here’s a close up of the old control board, still in its original project enclosure:

The red light is on, a good sign! The board was working fine, so I set about programming it specifically for the Flavin piece. Since everything was (temporarily) connected I figured I may as well get it behaving satisfactorily before mounting it up permanently in its new home.

I’d built this particular board before discovering Arduino, so it was based around a PIC 16F628. I like these chips because they have an internal oscillator (no external parts needed) and have enough input/output ports for smaller projects. Plus, there’s a couple free compilers out there.

I wrote up a new program in Hi-Tech C with a bunch of new functions for actuating the lights, only to discover it wouldn’t compile due to the math library needed for random numbers exceeding the available memory space on the chip.

My ideal solution would’ve been to just stick an Arduino chip on the board, but there was neither room to mount a new socket for it nor a matching pin-out (compatibility) with the existing chip.

Wanting to stick with the original plan of reusing hardware rather than building something new, I turned back to a previous (free) compiler in my toolkit: XCSB BASIC. It didn’t take too long to rewrite my C functions into BASIC, and soon enough I had the Flavin piece up and running to my liking.

I mounted the reprogrammed control board on the back of the piece:

Not the cleanest cable management, but it did the trick:

The chip still has 12 unused input/output ports, so there’s lots of room for expansion by the way of input sensors and additional outputs if need be. The Flavin piece is only using four of the eight available (yellow) relays already on the board.

Here’s a video showing it’s behavior. It has three modes which are randomly chosen for a random duration: toggle / change the state of a colour; only one colour on at a time; and any combination of colours. In each case, the colour to modify is random, as is the interval between colour changes. I like a lot of randomness

The video includes sped up and time-lapsed footage, as the actual timing of the piece varies between the speeds shown below and substantially slower; in an attempt to not bore viewers, I took a “flashier” approach to the video documentation.

[ As an aside about the music in the vid., normally for my videos I like to use some loops or beats I've already recorded, but in this case, I was coming up empty handed in my search for the right vibe amongst my existing recordings. So on went the drum machine, I picked a few sounds I'd previously tweaked, and recorded the soundtrack live into the video as a "voice over." I was quite happy with the results and perhaps it'll be the start of a new track? ]

I decided to name the piece “Flaven” after my misspelled BASIC file for the program.

Something that really became pronounced to me after animating a Flavin-like piece is the contrast between Flavin’s use of direct and reflected light. Seems obvious in writing, but the effect this new piece has when throwing light around an exhibition space is quite dramatic!

This piece and several others can be seen at the Conjunction Collective show in Toronto until November 8, 2009.

Pics and vids from the exhibition coming soon; in the meantime, check it out in person if you can!

The work of production is really reduction.

On Friday evening, Artengine’s new media Nite Ride exhibition opened, and I got to enjoy the first ride of the night, listening to Tim Hecker’s custom 5.1 channel surround soundtrack to a drive through the Gatineau Hills.

Guerilla mag has a great video from opening night that gives you a much better sense of the project than my prose:

Unfortunately I didn’t have a chance to go on the next ride for Marla Hlady’s work, but I’ll be back during the week, as Nite Ride runs until Oct. 31.

We had to leave the Nite Ride opening early as Deb and I had to set up for our DJ/VJ performance as The Latest Artists at Lotus Lounge in Ottawa later that night. We were booked by Exposure Fridays for their Halloween-themed party, and were excited to share another bill w/ Kevan Fraser.

With only an hour set time, we went straight to business with dark, rolling, minimal-tech tunes accompanied by synced, abstract and spooky-themed video — our specialty Not sure if we’ll get any documentation from this one, though, but we received lots of great feedback after our set.

Again we had to leave early to prepare for another commitment the next morning:

The Conjunction Collective’s exhibition, Civilization and its Discontents, opening on Saturday eve. in Toronto, for which I still needed to install my light portion of the show.

The organisers gave me free reign of the gallery basement for my lighting work, so I reprogrammed and refurbished a handful of pieces to display in the space.

Installation went really smooth thanks to dedicated assistance from Deb and my good friend, Dan. The opening party was a blast, and I received lots of positive feedback about my lighting work, which was really encouraging to hear from a Toronto crowd since it was my first lighting exhibition there.

Deb got lots of great documentation that I’ll share soon, but in the meantime, I invite you to check out this photo set by co-organiser, Jen Lee.

People are finding it easy to publish something without any controls. And this is the problem with the internet in general. There is so much information, and no one knows if it’s true or not. It’s just there. It’s an information monster.

From Resident Advisor’s recent interview w/ Ricardo Villabolos.

If you’re in Ottawa this Thanksgiving weekend, I invite you to swing through Westboro on Saturday afternoon to check out Cornucopia, Wesboro’s fall celebration. There’ll be street performers walkin’ the beat and lots more to see and do during this all day “animated sidewalk sale.”

As for the beats, I’ll be providing the tunes all day — alongside some surprise guests — and I’m sure we’ll have some entertaining moments thanks to MC duties by China Doll!

Here’s a quick vid from last year showcasing some sidewalk breakdancers, some antics with China Doll, and a serene moment celebrating art, set to the sounds of Ricardo Villalobos as the afternoon wound down

If you make it down, swing by the booth for a chat, we’ll be set up right here.  Oh, and if last year was any indication, there might be free pumpkins for grabs at the end of the day.

PS  If you thought that first Villalobos clip was something, check this one out.

Really diggin’ the new M-nus release by Clickbox + Run Stop Restore. Currently can’t get enough of the title track with the slide-y bass guitar and creepy almost off-putting vocals; then the solo synth-line part in the middle: nice dark/groovy stuff. This one will def. get some play at my autumn/Halloween gigs!

Also enjoying the painterly / water colour artwork of the recent Minus releases.
