Last night as we were preparing for the party, Eric broke out his camera and took this cool video of my LED Cylinder project. Thanks Eric!

More details on the project, including schematics and sourcecode, are available at http://dclausen.net/projects/ledcyl/.

If you want to learn how to make projects like this, check out our classes! We have several electronics and LED classes coming up, including Introduction to LEDs next weekend and Building LED Displays the weekend after that. Also you should come to our Party / Art of the Game Gallery Show tonight (Saturday, July 26, 2008) to see this project and a bunch of other cool things on display.

Since when were hackers the best thing happening in Avant-garde music? SINCE ALWAYS DUMMY!

This event is curated by Speaker Synth artist Lesley Flanigan.

excerpt:
This Wednesday night at the Tank, a group of amazing people come together for a night of performances based on amplification. It will be AWESOME! A really special opportunity to see such a great, eclectic group of performers all in one night. For my part, I will perform both my latest speaker feedback instruments and Bioluminescence with Luke DuBois. So please come out and join us all for drinks, fun, and sound!

now come check out this awesome show at the tank in NYC at 7:00 pm

So here’s a quick preview of the LED Array Jacket. I’m pretty excited it’s managed to light. Currently I am redesigning the driver circuit and boarduino to work with non-solid core wiring and to be more elegant and clean. But I thought this might wet your appetites.

The legoland matrix

This is a 256 LED matrix connected to Max7219 display drivers and programmed with an Arduino. Essentially, the Arduino is the brain behind the operation and the Max chip is the translator that speaks to the LEDs telling them when to turn on and off. The grid is separated into 8×8 quadrants and uses 4 Max7219 chips to drive a total of 16×16 rows and columns. The Arduino gives the Max7219 chip random numbers 0-8 to the digit and segment pins and lights up a single LED in its quadrant. By programming (with LOTS of help from Dino Dai Zovi) the display at 8000 one LED per grid lights up individually at a slow rate. Since computers don’t have opposable thumbs, this is where the human comes in. You get to put the legos where the computer instructs you to if you’re obedient. Once the computer has created its sculpture you can set the display to 3 or 4 and make it blink really fast turning it into a mesmerizing machine! Or a chandelier if you turn it upside down. You can also program patterns in the code rather than randomizing it, imitating lego instructions to build an object or map out visual data. The clear lego plates and bricks were found on ebay. The grid was built by Alicia Gibb and Becky Brauer. Look for upcoming LED Matrix building classes at NYCR.

Gertrude: An Led Drawing Machine by Chris McDonald

My good friend Chris McDonald made this extra-great, 2-axis drawing machine for doing time-lapse photography.

Here’s the info from his personal website vanita phone company: 

Gertrude uses two stepper motors to move an LED in a very high resolution x/y plane. The movement of the LED is photographed using exposures usually between 30 and 90 seconds. Gertrude can either be programmed to “print” a design automatically (“Christopher & Daniil”, the Hell Yup!: Scanlines shots) or controlled live via a joystick (Open&Close portrait series).

Video: Dave Clausen and his LED oscilloscope project

Learn how to use shift registers as Dave explains his LED oscilloscope project at NYC Resistor’s bi-weekly Microcontroller Study Group.

UPDATE:

We’ve all gotten excited about this project, and Dave has agreed to open up his code and document everything, but needs a little help creating the schematics, etc. Zach ‘Hoeken’ Smith of RepRap will be giving a demo on Eagle at the next NYCResistor Microcontroller Study Group meeting so we can create the schematic, and get started documenting this whole project from start to finish!

Soon after that, we’re looking to create a kit for this project to make it easy for people to duplicate it at home. It’s a great project for learning audio processing, breadboarding using arduino, shift registers, and how to make and use an LED matrix. That, and it’s just cool. I want one of these for my desk.
