Please allow additional travel time.Companion Cube
Hexadeca scrollerDisorient Pyramid, mini version

A few months ago we introduced Octoscroller, NYC Resistor’s eight-sided RGB LED matrix display built with jumbtotron RGB LED matrix panels. The interface “cape” has been reworked twice and the LEDscape source code has been refined to handle various arrangements of panels, from rectangular displays to larger polygons to six-sided cubes and minature pyramids. We’ve also updated the code to receive from OPC and other transmitter formats, in addition to local drawing into a user-space framebuffer.

Jumbotron time!
The good news is that we finally have the supply of panels and control boards to offer a class on building your own mini-jumbotron or other shaped display! Included in the class fee are eight of the 32×16 RGB panels, a BeagleBone Black with the Octoscroller^2 cape (capable of driving up to 64 panels at 30-60Hz), a 10A power supply and the wiring to put it together.

You can print or lasercut your own brackets based on how you want to arrange your panels — OpenSCAD and STL files for the octagon, cube and flat brackets are in the source, and Misumi 15mm extrusion works great for larger structural pieces.

I’m Trammell Hudson, the primary author of the LEDscape code and the designer of the controller boards and I’ll be leading the three hour workshop at NYC Resistor on May 24th. In the class we’ll solder together the board, install the software on the BeagleBone Black, wire up the eight panels and write a simple program to draw on the panels. I’ll also walk through the PRU firmware that handles the real-time interfacing, although this programming experience isn’t required. Buy your tickets here!

Interactive Show

Get that Club Mate cold and those soldering irons hot because it’s time for another Interactive Show! We’re putting out the call to hackers around the globe to come show your stuff at our annual party.

This year there’s no theme– it’s a free-for-all! Have something blinking and beautiful? Something that bleeps or bloops? Anything interactive goes!

This year’s show will be June 7th. If you’re interested in being part of a show, drop us a line at ishow@nycresistor.com! Try to get in touch by May 7th so we can make sure there’s space for your project. Hope to hear from you soon!

Props to Olivia Barr for our awesome gif flyer this year!

te_card_reader-300x300Got a shiny new 3D printer, but not quite sure what to do with it? Interested in learning to make your projects move? Sign up for “Intro to Mechanisms” on May 10th and get a gentle introduction to making stuff spin, wobble and reciprocate using things like gears and cams. We’ll also explore more advanced control mechanisms like Geneva Drives and Jacquard-style Punch Card readers, so you can live out your steampunk fantasies and setup your own desktop Dickensian sweatshop!  Taught by Chris Fenton (chris on thingiverse).

Above is a photo of the building that OpenStack ( nova at least ) was born in. That’s node number 6 on the internet, and the home of E root server. The dishes while no longer in use, used to provide internet to places like scandanavia. I also used to work there, as part of the Nebula Project.

Today the OpenStack foundation released their latest version of the software, code named Icehouse. Named for a street in Hong Kong ( where the last developers summit was held ). Many are just calling it Igloo because it’s easier. Anyways, to celebrate the new release of OpenStack, I’ll be trying to start up an OpenStack study group.

That will be on May 21st starting at 6:00 PM ( 18:00 ).

NYCR floor painting: BeforeNYCR floor painting: before
Did you ever notice how beat-up the floors were at NYC Resistor? Four years of rolling chairs had done horrible things to the paint, so we did something about it last night.

Everybody pitched in with a massive effort. While the painting only took from 22.8 to 73.3 .beats, the spring cleaning, organization and preparation took all weekend.

Zach was the last Resistor painting and escaped by taking the elevator. We turned off the lights and let the first coat dry overnight. The second coat will be dry in time for Craft Night. So come hack with us on a freshly painted floors!

Nick and Sayaka Vermeer, Olivia Barr, and William Ward have been working hard for the past couple weeks on an exciting project with the Brooklyn Ballet. We are transforming the dancers’ costumes into interactive performance pieces. Our contribution consists of six LED snowfall tutus for the ballerinas, one Pexel shirt for Mike “Supreme” Fields and six sparkling LED hair accessories for the young ballerinas. The dancers will be performing the snow scene from the Nutcracker in the Brooklyn Ballet‘s Vectors, Marys, and Snow performance from April 3rd to April 13th. Please support the project through our Kickstarter! There you can also watch an interview with Nick and Lynn Parkerson, founding artistic director and choreographer of Brooklyn Ballet. We’d really appreciate your donation to further our work! All our hardware designs and code are open source, and we hope to see more creative works mixing technology and dance.

Snowfall Tutus: To accomplish the snowfall/glitter efffect we’ve added LED lights, motion sensors, and custom coded/fabricated microcontrollers to the tutus. The sensor we used is called an accelerometer and its placed at the waist of the corset. It reacts with with movement of the dancer by increasing the amount and brightness of the LEDs with more vigorous movement from the dancer. Nick found a remarkably strong ultra flex 36 gauge silicone wire thats perfect for the supple construction of the tutus and its become a standard material at NYC Resistor for wearables. The wire connects 24 neopixels that are broken down into 6 strands of 4 pixels in each tutu. Special thanks to Max Henstell and Adam Mayer for helping in production. Take a look at this amazing video of our twinkling Tutu!

Pexel Shirt: Pexel Shirt is custom made for the dancer Mike “Supreme” Fields and is designed to interact with his pecks and arms. Mike is a popping artist and his dancing incorporates the flexing of muscle groups to create surface movement on his body. The shirt is activated by individual accelerometer sensors placed over his muscles that illuminate the LEDs through a Flora microcontroller. There are four sensors total, one on each peck and each wrist. When he flexes an individual peck it lights up. The lights on his arms are controlled by moving his wrists up/down or right/left. The entire piece is hand sewn including stitches in between individual pixel on the arm strands for optimum elasticity while still being secure. Watch the Mike in action here: Mike “Supreme” Fields

Sparkle Hair Clips: To accent the young ballerina’s costume we designed an LED accent on a hair clip. The clip uses a Gemma microcontroller and a strand of neopixels. The clear acrylic beads on the clip filter the LEDs and sparkle.

Please come out and see the show at the Brooklyn Ballet April 3rd – 13th and support our Kickstarter to fund the project!

Are you interested in programming and software but have never known where to begin? Some of our most popular classes have been our

Python!

introductory programming ones, and I’ll be teaching one this Saturday. The idea is to give students a gentle  introduction to software concepts using Python, a very widely-used but accessible language, and practical examples.

I don’t assume any prior programming experience: I’ll teach you everything you need to know to get started. Come and join us!

The Spikenzie Labs Solder:Time Desk Clock is a fun through-hole kit to solder together. It includes a snap-together lasercut acrylic case with a really nice red tinted screen that increases the contrast on the 20×7 red LED matrix. Plus it is totally hackable with quite a few unused pins available for expansion (like Holly’s sunrise alarm clock).

The kit is available from Adafruit and I’ve written more information on information on programming custom firmware for the Arduino-compatible ATmega328P that is the brains of the clock.

Voronoi shadows

Given a set of points, the Voronoi tessellation creates a set of convex polygons that each contain one point. They can also be used to randomly generate unique art pieces that cast shifting, lace-like shadows. This one was really quite beautiful until the candle burned through…

Read on for some scripts to make your own and tips for laser cutting them.
