Box2DFlash – Falling Text

August 25th, 2009

I'm so excited that I finally got to work on some experimental Flash at my professional employment. It is a nice change of pace to push an idea to the limits...and then some. In fact, I'm still not done working on the possibilities. This was only the starting point. Making text fall. Tie it into the Box2DFlash Physics Engine.

I want to give yet another shout out to Emanuele Feronato. If you are looking at this code, and are completely lost, he has EXCELLENT tutorials to get you started. Thats where I ended up taking my first steps in Box2DFlash.

Now in the guise of learning. I don't intend on going too indepth with the code...there is a lot going on. But hopefully, by breaking it down into phases, you can understand my building process. Something like this isn't accomplished in one chunk of code. It is build up by steps. At least the way I code. Read the rest of this entry »

New pics – FTIR II

August 18th, 2009

Wired IR LED rails, Acrylic and Base

Assembled Top, Rails and Acrylic

Wired IR LED rails, Acrylic and Base

1 inch spacing on LEDs. Black electrical tape to help with light control and sliding prevention.

Powered by an old computer ATX power supply (12V)

IR LED rail

Drilled with a drill press for increased accuracy compared to my first table build.

IR LED rail

Loctite, excellent to hold LEDs in place. Not terribly difficult to remove if any burnout.

Acrylic edge flame polished by my uncle (a plastics fabricator company owner)

And the width of the acrylic, 16:10 ratio to work with a Toshiba TDP-EW25U

Still Swimming – FTIR II and Capacitive

August 13th, 2009

Temporarily, I have shifted from the software side of things back to the hardware. For those of you looking for more Flash experiments, my appologies. The experimenting is going to be taking a little break while I work on 2 new hardware projects.

1. New FTIR table

Back to were I started, making a new FTIR table. I don't have everything planned out. I'm letting things come together organically. But here are the basic ideas I'm going for.

  • Almost 50" diagonally
  • Toshiba EW25U Projector
  • Rosco Grey
  • squeegeed compliant layer, rolled on method compliant layer
  • 36" max height (or as close as possible)

So far so good, I've slowly been getting all the pieces I need, and now I'm finally beginning fabrication. LED rails, acrylic holding frame, table spec design.

2. Capacitive Foil

I finally received some income I've been looking forward to for quite a while. After debating with myself my ultimate intentions will all this multitouch experimentation, talking team up with a brilliant business mind, and a can-do personallity. I contacted a local distributor about purchasing a piece of capacitive foil.

True, it may not be multitouch (yet), but I've wanted to experiment with this kind of stuff from the start. And large scale, I mean 50" diagonal again 16:9 ratio. Something I can use to create a full scale demonstration of capabilities. Not just and idea, but an actual physical implimentation to show off.

The capacitive foil is on the way. I have a large piece of acrylic waiting for it to be applied on, I just need to build a stable frame to hold it up. And be able to swap from portrait to landscape.

And not to mention my practice of cross communication between computers and flash (in real time no less). There are interesting things right around the corner.

Upcoming Art/Tech Events

The Bridge Project - 36 Views of a Bridge with Alexander Boxerbaum

Collider Exhibition Series: Interactivity and New Media - new installation still in planning phase

until then, happy experimenting!

LaserDraw – multitouch extension

July 28th, 2009

Now feels like a good time to get back into it. Especially coming across this site:

asluv

laserdraw1Sure, it doesn't seem like there has been many recent posts. It can be hard juggling a life around experimenting. It doesn't make it any less awesome when you see something and get inspired. Here is what I found, a AS3 script that would not just draw a line, but so nice ribbon curving and add a glow around everything automatically. It is just begging to be multitouchable (that sounds a little dirty now that I think about it).

http://asluv.com/2007/09/18/laser-draw-as3-experiment/

"This experiment uses the AS3 drawing methods to generate an organic mask formed by several pairs of points linked with curveTo.

The generated shape masks a simple radial gradient and the result has a GlowFilter and a DropShadowFilter applied to it."

It works great, no doubt about it. But the source is there, we can take it a little further. Now I got a lot further than expected working on it, and the night is starting to get late, so I'm going to try and condense the main ideas I want to remember that are the most useful.

36 Views at Ingenuity Fest – Report

July 14th, 2009

The Artists First off, I'd like to say thank you to everyone who came out to support art, music and technology in Cleveland. I feel very proud to have been part of such an event. Not only was the public curious and interested in everything that was going on, even the fellow artists, musicians and technologists were eager to enjoy the whole festival.

But now, down to it.

36 View of a Bridge

The main question everyone had when I got back to work on Monday was, “how did it go?”

It went Awesomely.

Sure, there were a few kinks to work out at first. Two of the videos were still being converted to h.246 compressed videos so they could be played by flash in HD. And the voting on the table had a few bugs because of the missing videos. But Alex and Andy got them wrapped up ASAP and in they went.

Smoooooth sailing from then on, right? Well, not exactly.

The multi-touch table was wrapped in a cloth for appearance sake, and I didn't realize how much heat it would trap in. Within 2 hours, the mirror I was using to reflect the projector slowly started to melt off of the frame that was holding it! Oh boy, quickly I got a block of wood to secure the bottom section and grabbed the duct tape (duct tape is my personal hero in times like this). Mirror is back on track and luckily I never nudged the camera so the calibration was only off by what looked like 1/4 inch—not horrible. And aside from that, only the Flash on the multi-touch table got a little overwhelmed a few times over the course of the weekend.

Saturday morning. Got the iPhone voting functioning—that was yet another highlight of day. People were capable of voting for videos outside of the exhibit if they felt so inclined. And it was cool to see the playlist randomly change order at any given time the table.

On Sunday the entire setup ran error-free for 5 hours and 59 minutes! Not bad for a first time art/tech exhibitor, in my opinion.

Word is Spreading – Ingenuity Fest – 36 Views of a Bridge

July 4th, 2009

The news is going out, one week from now, Ingenuity Fest.
Heres a list of more information:

Flash Communication Ninjutsu

June 17th, 2009

For 36 View of a Bridge at Ingenuity Fest 09 Cleveland OH

So as it happens, after most client meeting (client used very very loosely). It turns out the first way I was thinking about how to build this app wasn't exactly how it was originally vision. Honestly I was a little relieved, because what the new idea is made more sense to create. The only problem, how to pull it off? Read the rest of this entry »

Promotion Time ~ 36 Views of a Bridge / Ingenuity Fest

June 12th, 2009

Another video sample is up for viewing from Alexander Boxerbaum at Vimeo. If you don't know yet, I've been working with him to have a multi-touch live voting and playlist control interface at this year's upcoming Ingenuity Fest in Cleveland OH. Which is the main reason things have been quiet around here lately.

Enjoy the video, I'll try to keep up with some more experiments soon as possible.

FTIR to DI Conversion

June 9th, 2009

I've got some upgrading going on. First, I procured a new projector. I was worried the old one was running out of bulb life, and I borrowed it. Similar throw distance, well a little less. And I decided to switch from FTIR to DI for an upcoming event. So now I can just get a now projection screen and solid surface and be set until the next build.

Multitouch Magnifier – AS3 experiment

June 2nd, 2009

Fire up the SVN, there's an new experiment to check out.

multitouch magnifier - AS3 from Chris Yanc on Vimeo.

If you don't have all the files, you can find them here: http://code.google.com/p/multitouchas3experiments/source/checkout

For this one, you are going to need Flash CS3 or CS4 as far as I know. I don't know how FlashDevelop or Flex will translate. We will be using assets from the Library which are linked to AS files. I'm thinking it'd be best to go through the files. Read the rest of this entry »
