Syzygryd Software Preview

A short video showing off our early software design for our latest project, Syzygryd.

The sequencer and the display layer are written in Processing, the iPods are running touchOSC by hexler, and the computer making the noise is running Ableton Live with Native Instruments’ Massive. We’re working on getting better sounds set up for it, now that we have the software generally functioning.

Thanks a ton to Audrey, Yosh, and Nicole for editing, and Ian for filming.

Timescale Project Proposal Submitted

January 28th, 2009 Ed Hunsinger Posted in Timescale No Comments »

Morley with Timescale Proposal

Timescale is a new project from Ardent Heavy Industries, the not-fire-centric parent group to Interpretive Arson. Timescale is a journey through 4.57 billion years of planet Earth’s geological and biological evolution, extended across one mile (5280 feet) of open playa. Beginning with the formation of the Earth from a cloud of gas and dust, participants will traverse through time — advancing two million years with each footstep, culminating at the present day. Each chapter in Earth’s growth is highlighted along the way, allowing participants to appreciate the transformation of our planet and the exponential complexity of living things. Each chapter in Earth’s history will be a 6.5ft tall 8in x 8in column of concrete with art representative of that chapter inside.

The proposal for Timescale was recently submitted to the BMORG for funding. I’ll let Morley explain this unique proposal:

Hello fabulous beautiful creative people!

I’m very very excited to share with you the fruits of many weeks of devoted effort on the part of myself, Nicole, Ian, Star, Colin, Nina, Brody, Reed, Ramon, Ed, CTP, and countless friends and reviewers:

Last Thursday night, Nicole and I submitted the hard copy of our proposal at BMHQ. The hard copy, in this case, consisting of a 12″ concrete cube, hollow down the center, with a 52.8 ft long rope inside, marked out at 1/100 scale of the final project. The cube was finished top and bottom with mild steel plates, with the printed/bound proposal mounted atop the top plate under a piece of clear 1/4″ acrylic. And the whole heavy shebang was held in a lovely rope sling with wooden handles, fashioned by the ever-talented Ian.

Rocks and concrete and love,

Engine test #2 CAD

November 25th, 2008 raindrift Posted in cad, Hitodama, make 2,294 Comments »

Nicole, Jonathan and I spent the evening finishing up the design for Hitodama test engine #2.  It’s a cool-running liquid propane/compressed air thruster, with a theoretical thrust of 96 Newtons.  We’re opting for safety over performance, which means low combustion chamber temperatures and lots of air pressure.  The complete engine, including bolt flanges, is 9cm diameter.  Hopefully we’ll be able to reduce that slightly for the production version.  A complete set of design specifications should be forthcoming.

Next come the high-pressure air and nitrogen-pushed propane systems.  Just because we said it’s safe doesn’t mean it’s simple…

Hitodama test engine #2

This is a picture of the complete engine.  From left to right, you see the nozzle (including diverging and converging sections), the combustion chamber which contains a titanium flame holder, the fuel injector, and the injector cap.  Air and propane enter and mix inside the flame holder.  Meanwhile, a bunch more air is injected outside the flame holder.  The entire mass of combustion gases are heated to about 1000C, and ejected from the engine at Mach 2.5.  At least, in theory.  We still have to build it.
