Tetris on a building

Brian Benchoff — Wed, 05 Oct 2011 23:01:02 +0000

Around a year ago, a bunch of blinkenlights were installed in the HCI-Building of ETH Zürich. These LED spots weren’t interactive and only showed hardcoded patterns. Of course a bunch of LEDs demand interactivity, so for the first-semester party this year a giant game of Tetris was built on the side of a building.

There’s no official build log, but from what we’ve learned, the LEDs are connected to a DMX controller that is in turn plugged into a computer and the University’s ethernet. For the command and control of the Tetris game, a USB joystick was connected to an old Dell that was pulled out of the junk pile.

The software for the project, LED side of the project was written in Visual C++ reusing old Tetris routines and example code from the DMX controller. For the controller portion, everything was written in C. The controller simply dumps chars into a TCP port on the second computer. While the Tetris board was only 3 pixels wide, there was a fairly massive queue of people wanting to play.

BAMF2011: Bloxes, a building kit with a nifty pedigree

Not every cool hack needs to involve microcontrollers, LEDs or other bling. We were initially drawn to the Bloxes display simply because we love a good multipurpose construction set, whether it be Lego, 80/20 aluminum, or in this case, a system of interlocking cubes formed from six identical pieces of corrugated cardboard, cut and scored in such a manner as to form a surprisingly sturdy little building block. They can become simple furniture, groovy Logan’s Run-style room decor, or the all-important kids’ forts…then later dismantled and made into something else.

A elegant concept executed in the humblest of materials…we were already infatuated. We were blown away then to learn of Bloxes’ background: they’re a 1970s brainchild of computer pioneer [Jef Raskin], perhaps best known as the “Father of the Macintosh.” [Raskin]’s son and daughter [Aza] and [Aviva] revived the Bloxes concept in 2008 and now sell kits through their web site. Even if you’re not at the Faire, they welcomed readers to use the discount code MAKERFAIRE2011 (good through June 12th 2011, limit one per person), which will net you a kit of five Bloxes (30 pieces, some assembly required) for $12.63 vs. the normal $15.59.

Crash Space Takes on the Machine

It’s that time again, time to take on the machine with the Hackerspace, Crash Space (and part two)! The team of Californians set out and successfully turned the front of their building into a musical instrument, similar to [David Byrne's] Playing the Building. When a pedestrian walks by they set off distance sensors, which in turn actuate mallets that strike particular objects to produce a tone. We were pleasantly surprised at how interactive the installation was, even if it didn’t sound that great. But will it be enough to beat out the previous two teams? And how will it do up against Artisans Asylum’s not what you’re thinking Breakfast Machine next time?

Playing the Building with David Byrne

Juan Aguilar — Wed, 04 Jun 2008 02:00:00 +0000

Do you remember the solenoid concert that used a sequencer to control several solenoids striking different surfaces? Musician David Byrne has taken the concept and executed it on a much larger scale with his “Playing the Building” installation in an old municipal ferry terminal in New York. Devices that bang the girders, rattle the rafters, and blow through the pipes of the building are attached to the only object inside, a weathered pipeorgan. Every key is wired to different device in the building, each producing a unique sound. Attendees are invited to fiddle with keys of the organ to produce sounds from the building’s various materials, thus playing the building like an instrument. Here’s a video from the installation.
