"Electric Tenement" reacting to Tweets @ OpenOttawaLibre 2011

On Sept. 28 2011 I was fortunate to partake in OpenOttawaLibre 2011, an “unconference” that brought together a diverse group of “creatives” from the business, technology, and art sectors in Ottawa. Although the agenda of the day wasn’t entirely clear until the event started – in true “unconference” style – the day was actually a facilitated discussion workshop featuring multiple streams of interest, all derived from the central question:

what do we need to do to create a place that sparks opportunity for creative thinkers to collaborate and innovate for a better Ottawa?

From a general networking perspective, OOL11 proved to be a productive opportunity to meet new people and organizations with overlapping interests and mandates in the city – one particular example standing out being the desire expressed by many groups and individuals to have an Ottawa-based electronic arts festival. Although Ottawa is a relatively small city, it never ceases to amaze me how isolated different groups with similar agendas seem to be here; OOL11 provided a great meeting ground for such groups to discover one another. The enthusiasm generated at the event was also contagious, and served as a valuable reminder of the creative potential in Ottawa; I wish there were more events like OOL11 to help bring a unified focus to our efforts.

From a personal perspective, I was happy to bring new exposure to Artengine’s Electric Fields festival to a targeted, interested audience, as well as meeting a new group of potential collaborators from The City of Ottawa’s Community Arts Program, The Ottawa Art Gallery, and Apartment 613.

I was further fortunate enough to be one of 4 artists invited to showcase technical artwork. I chose to show Electric Tenement (the working name for the lighting tower debuted at Urbana 2011), programmed to react to tweets tagged #OOL11 (shown in the opening photo, above).

Guerilla Magazine wrote a feature on the piece and its role at OOL11 here.

Many thanks to Julie Dupont and Caleb Abbott at The City of Ottawa for all their hard work!  Make sure to check out the OOL11 webpage for more info and ongoing discussions.

Background

Chinatown Remixed is an annual, art festival in Ottawa’s Chinatown district.  For one month each spring, the merchants and restaurants of Chinatown welcome artists’ exhibitions and performances.

Having exhibited lighting installations back in the 2010 and 2009 festivals, Deb and I wanted to try something different from, and more spontaneous than our usual “plan and execute” lighting approach.

After a conversation with one of the primary organizers, Don Kwan of Shanghai Resto, we did indeed come up with something different for the 2011 edition (May 15 – June 15).

Lightfair International 2011

Last week I traveled to Philadelphia to attend Lightfair International 2011, a huge lighting conference featuring an immense trade show floor and a full schedule of lighting-related seminars.

While there, I was guest blogging for Philips’ LightCommunity on their new Events blog.  My first post focused on advancements in LED street lighting, my next post discussed issues surrounding general LED lighting in the home and summarized the keynote by Ingo Maurer, and my wrap-up post captured my impressions of the trade show floor.

Since the majority of the conference is focused on technical learning and driving product sales in the architecture, retail, and commercial sectors, there isn’t too much to take in from an artistic standpoint.  I was pleased, however, to attend a refreshing and inpiring seminar by Leni Schwendinger about her public lighitng projects.

As I see it, the increase in 1% for art programs coupled with the continual advancement of LED architectural lighting is a sure fire recipe for more exciting public lighting projects, so I hope to see greater emphasis on public lighting projects by events like Lightfair International.

Urbana 2011

Intro

Urbana is an annual fundraiser hosted by Dharma Developments where proceeds raised support community programs with the goal of preventing homelessness in Ottawa. This year, URBANA is helping Action Housing / Action-Logement, an Ottawa-based charitable organization that assists low-income individuals and families to find and maintain safe, affordable and adequate rental housing.

Each annual Urbana hosts an artistic feature from local artists.  This year, Dharma contacted Deb and I for an interactive lighting installation by The Latest Artists.  The theme of “an on-going light for housing rights” was developed by integrating our medium of light with the need for the awareness of housing (and other social/charitable) issues to remain front and center: these issues don’t simply get solved with single instances of involvement or donation, but require constant attention to address.

This theme lead to the proposed installation: a large lighting structure, architecturally-inspired, requiring on-going crowd interaction to propagate its behavior, or,” keep the lights on.”

Some Google Sketchups were created:

This first sketch shows the six foot structure with an assortment of illuminated windows, akin to an apartment tower at night, w/ residents inside watching tv.  The planned interaction for this mode was to have the crowd turn on the windows by touching them, after which the window remains lit for a period of time before turning off again; constant interaction is needed to keep the piece illuminated.

The sketch below shows off the full color (RGB) capabilities of the piece. Animations like this could be used in a game play mode to signify winners:

DOTKLOK software 1.3

New “big font” time display

If you haven’t already, it’s time to update your DOTKLOK!  When you plug your DOTKLOK in, the software version will briefly be displayed (if there is no display, you are running code version 1.0 or older).  The latest release is version 1.3, now available at the DOTKLOK project page in the Source section; you’ll also find the instructions for updating your DOTKLOK in the usage instructions document.

There’s been a lot changes, updates, and improvements made between version 1.0 and 1.3, so I thought I’d summarize them here.  In addition to a handful of behind-the-scenes improvements to the inner workings of the code, the total animation count has almost doubled from the original 8 animations to the current variety of 14!

As shown in the photo at the top of this article, I’ve created a new “big font” time display that replaces the original “basic time” display; this was done both to take more advantage of the total screen space, and to add more variety since the “basic time” and “game time” displays were very similar (aside from the occasional visit from Pacman and friends).

Here’s a rundown of the new animations:

Blog love

DOTKLOK’s been getting lots of blog love since the official launch in January.  Noteable appearances include Make, Create Digital Motion, Laughing Squid, CunchGear, Hack A Day, and a print feature in Korean trend magazine, Metatrend:

The first customer-created review vid also surfaced this week:

I keep an on-going list of press on the DOTKLOK Facebook page.

New DOTKLOK animations

This past week I wrapped up version 1.1 of the DOTKLOK firmware, adding 3 new animations:

Analog mode: a minimal depiction of a standard analog clock face.

Morse code mode: hours, minutes, and seconds represented in Morse code glide across the screen at random velocities.

and Game Time, where the screen is randomly cleared each minute by video game icons such as Pacman, Tetris blocks, or Space Invaders; the updated time then fades back in:

DOTKLOK is available as a kit, or fully assembled, with a red or green screen from my Etsy shop.

“Phenomena” @ CUBE Gallery, Feb. 1-27 2011

Phenomena is a group exhibition @ CUBE Gallery featuring seven artists’ take on climatic, astronomical, or geological phenomena.

Alongside work by Aili Kurtis, Paul Schibli, Guy Lavigueur, Jennifer Gibbs, Reid MacLachlan, John Roth, and Tony Broderick, I’m debuting work exploring new themes for me: a light piece controlled by the colour of the sky.

The light patterns displayed by Sky Spectrum are directly related to the current sky conditions above Ottawa’s Peace Tower.  Every few minutes, the sky portion of the Hill Cam is analysed to reveal the average red, green, and blue components present in the sky.  The light fixture responds according to the various relationships between these values, presenting an altered view of the sky above, revealing colour details and relationships invisible to the naked eye.

The literal reference to the sky is echoed by the graphic processing portion of the piece which takes place on a remote webserver, in essence utilizing “cloud computing.”

Most of the work indeed takes place on my webserver, where a PHP script analyses the current Hill Cam pic with the GB library.  A small hardware module (hidden in the gallery) consisting of an Arduino development board and ethernet shield fetches the data from the web every few minutes, and sends the data via XBee radio to the light fixture, which is controlled by a custom board with an ATmega328 (running the Arduino bootloader), TLC5940 for driving the LED strips, and an XBee.

The code is only preliminary at this point, and I plan to analyse the daily data collected from the sky to make a growing library of light patterns and blends.  I’m also excited about how scalable the concept is, and look forward to working with this idea on a larger scale.

The Phenomena exhibition runs until Feb. 27, so if you’re in the Ottawa area, please drop by CUBE Gallery (1285 Wellington Ave., W) to check it out.  The best time to view Sky Spectrum is between 4 and 6 pm when the sun is setting and the sky changes relatively quickly :)

DOTKLOK launched!

As you may have noticed from the sidebar on the right of this page, DOTKLOK “unofficially” launched before Christmas when I quietly put it up on Etsy, planning to spread the word during the beginning of 2011 . . .

Well, things got started for me when it was picked up over the holidays by a handful of blogs, including OhGizmo, Totally Cool Gadgets, Smidigit (Sweden), Rock N Tech (Brazil), Gizmodiva, GeekAlerts, The Vine (Australia),  HomeDosh, dubbing DOTKLOK “one of the coolest clocks ever made,” Technabob (UK), and a major source of those first orders, the German Engadget site.

The internet did its magic: I received a bunch of European orders which pushed me into production mode.

Now that a dedicated webpage including documentation is done, I feel safe saying that DOTKLOK has officially launched :)

For the final “1.0″ design, I opted to put the buttons on the sides, which not only makes them easier to use (as opposed to along the bottom edge), but also makes it possible to repurpose or adapt DOTKLOK so two people can play a game of Pong — definitely something coming to a future firmware update.

Here’s a vid showing some patterns operating on the 1.0 hardware release:

DOTKLOK is available either as a kit (fully illustrated instructions included), or fully assembled and programmed, ready to go!  It’s available in red or green versions as well.  At the moment all sales are handled through my Etsy page.

Here’s a few reactions from the first lucky owners:

“Received the clock in time to give to my partner as a b’day present today. It was a great hit and best part is I get to enjoy it as well”

“The clock arrived a couple of days ago. Looks great on my living room wall!  I really like the Dotklok. The parts are high quality, beautifully finished faceplates and assembling the kit was a lot of fun! Thanks for making this really cool clock!”

I’ve set up a Facebook page to upload user pics and as a support forum and place for people to make suggestions for future animations.

Next up, a promo/press sheet and then the first real promo push . . .

PCBs

After making my own PCBs for several projects and finding the process sufficient for small runs and prototyping, I’ve decided its time to make the leap to professional manufacturing.   The first design I sent off was a carbon copy of the Electric Window 4 single-sided PCB that I’ve been home etching:

This was a fairly simple process of generating gerber files for the bottom layer, the drill file, and cleaning up the top silkscreen (label) layer:

Since this design is bigger than Eagle CAD’s freeware limitation of 4″ x 3″, I used FreePCB which has its pros and cons in comparison to Eagle, subject to another article here sometime . . .

The size of this design also put it beyond the 4″ x 4″ prototyping service at Seeed Studio which I’d been wanting to try, so after a recommendation from the folks at Kwartzlab, I went “local” with Priority Circuits in Kitchener.  I was happy to find a domestic solution for PCB fabrication.  The prices were reasonable, and their service was responsive.

Although the above board is for Electric Window 4 fixtures, having a bunch made has led to collaborating with Deb on some new pieces — with custom graphic inserts animated by the LEDs — for CUBE Gallery’s Great Big Smalls show this December; pics coming soon . . .

After getting comfortable with the process of preparing a design for manufacture, it was on to the two-sided DOTKLOK design, the size being well within the “confines” of the freeware Eagle CAD version and Seeed Studio’s prototyping service.  Although several more layers needed to be generated — top and bottom copper layers, silkscreen layer, drill file, and solder mask — Seeed Studio provides a CAM job for Eagle that takes care of all this for you, making it quite painless to transform this:

into this:

The price and speed of the service was great, and I’m happy to have a set of working boards after my first attempt:

Just in time for an upcoming workshop with Cybersonica that I will be facilitating via Skype from Ottawa, where the first batch of DOTKLOKs will be made :)

Full kits will be ready soon!

Resource-wise, Sparkfun has a great series of tutorials on working with Eagle files, and as always, Adafruit has a ton of invaluable info.
