Some days ago, I finished the first public version of my audiovisual virtual machine, IBNIZ.
I also showed it off on YouTube with the following video: As demonstrated by the video, IBNIZ (Ideally Bare Numeric Impression giZmo) is a virtual machine and a programming language that generates video and audio from very short strings of code. Technically, it is a two-stack machine somewhat similar to Forth, but with the major execption that the stack is cyclical and also used at an output buffer. Also, as every IBNIZ program is implicitly inside a loop that pushes a set of loop variables on the stack on every cycle, even an empty program outputs something (i.e. a changing gradient as video and a constant sawtooth wave as audio).
How does it work? To illustrate how IBNIZ works, here's how the program ^xp is executed, step by step: So, in short: on every loop cycle, the VM pushes the values T, Y and X. The representation in the figure was somewhat simplified, however. So, what's the point? Databending using Audacity « Antonio Roberts. Thanks to some help on the Audacity forum I finally know out how to use Audacity to databend.
Previously I’d been using mhWavEdit, which has its limitations and just doesn’t feel as familiar as Audacity. From talk on the various databending discussion boards I found that people would often use tools like Cool Edit/Adobe Audition for their bends. Being on Linux and restricting myself to things that run natively (i.e. not under Wine) presented a new challenge. Part of my task was to replicate the methods others have found but under Linux. My ongoing quest is to find things that only Linux can do, which I’m sure I’ll find when I eventually figure out how to pipe data through one program into another!
Here’s some of my current results using Audacity: Just so you don’t have to go trawling through the posts on the Audacity forum here’s how it’s done. Next, download Audacity. Import Raw Data. Modkit. Futuristic and Unique Wallpaper with LED – LED Wallpaper. Futuristic and Unique Wallpaper with LED This is an unique wallpaper designed by Ingo Maurer from Architects Paper.
This is a great idea for wallpaper that will not only make your interior looks great but also illuminate your room. The LED light can be dimmed and hung in more or fewer strips and lengths according to the architecture and furnishing of a room. The surface has computer-chip motive with blue and red LED. This will make your wall become interesting. RGB Murals Use Colored Light Filters To Create Beautiful Optical Illusions. Carnovsky is a creative duo comprised of two Milan based artists, Francesco Rugi and Silvia Quintanilla.
Their latest project RGB looks at image creation through a new lens. Each of the RGB images are made up of three layers represented by primary colors. This starting image is discombobulating and difficult to read. Lines blend together into a rainbow swirl and it’s hard to grasp exactly what you are meant to be seeing. Viking Helmet with OctoBrite Fiber Optic RGB LED Mohawk. A friend sprung this project on us at nearly the last minute...he wanted a light-up mohawk on his Viking helmet.
Fortunately he already had the helmet, and we already had plenty of LEDs and raw materials. Planning The main obstacle turned out to be the fiber optics. We discussed several options; it's pretty easy to locate bulk art-grade fiber optic spools, but cutting a few thousand fibers didn't sound like a feasible task considering less than a week remaining (plus lots of other tasks demanding spare time after work). And we had no way to easily tell how stiff the fiber was, or if it would try to curl up. I remembered seeing street vendors selling light-up wands with fiber optics. This needed to be compact, and the helmet needed to be audio reactive too, so I also grabbed some parts from Sparkfun: Arduino Pro Mini, Electret Mic Breakout, and MSGEQ7 Spectrum Analyzer.
The LEDs were easy...four OctoBrite CYANEA modules. Building. Ch00ftech Industries. I made a pair of light up Kanye West glasses for New Years!
Firstly, I want to say that I completely ripped off this idea from my very talented friend Jordan. The electrical design is mine, but the fashion design is all hers. I highly recommend you pay her blog a visit to see what kind of other stuff she's cooked up. Electrical Design This was my first time dealing with audio from scratch. The audio signal path has a few stages: Gain Right off the microphone, the signal is given a half-rail bias (provided by U1D) and sent through a gain stage.
Having never dealt with an electret microphone before (besides my ch00f-o-scope which hardly counts), I didn't know how much gain I was going to need. Low Pass Filter This stage is pretty straight forward. Freq = 1/(2*pi*R*C) In this case, that's around 50Hz.
