Octoscroller
Hexascroller has been a central fixture at NYCR for the past few years, with a few ups and downs. It’s replacement, Octoscroller, improves on our classic message alert polygon by having two more sides and two more colors of LEDs.…

I like to take things apart. Sometimes they work when I'm done.
I've been a member of NYC Resistor since 2010 and you can see more of my projects at trmm.net.
Disorient Pyramid at Burning Man 2013
This year the Disorient Camp at Burning Man built a 7m tall pyramid with over half a kilometer of LED strips. Several artists developed patterns for the panels, including Disorient founder Leo Villareal and Jacob Joaquin from Fresno Idea Works.…
Oscilloscope class
One of the most powerful tools in debugging circuits is the oscilloscope — it allows you to visualize your analog and digital signals at millisecond or microsecond time scales. This 18 August class at NYC Resistor will teach you basic…
LEDscape
Are you building a giant LED display for your hackerspace or Burning Man and need a way to control multiple kilometers of LED strips? Are you tired of running massive USB hubs of Teensys for each row? Then you might…
Future Crew
Last month we introduced Future Crew, and at the 2013 Interactive Show we finally unveiled the fully mostly operational game stations. There were five stations in the final design, and in keeping with the show’s “Digital Archaeology” theme, each was…
Space Rocks
Cathode ray oscillographs weren’t just used for reading tweets in the 1940’s, they were also used as vector displays for serious astronomical simulations and training systems like “Space Rocks”. You can play it at the 2013 NYC Resistor Interactive Show!…
1930’s Teletype USB interface
The Teletype Corporation Model 15 “typebar page printer” is a beautiful piece of equipment from the 1930’s. While the interface has much in common with modern serial communication standards – start bits and stop bits, asynchronous clocking, idle-high conditions —…
Vector display Twitter client
It’s a little known fact that during the 1940’s the premier Twitter client was a cathode ray oscillograph vector display, such as this DuMont Labs 208B. The 15×12 character resolution was perfect for a 140 character tweet. This one has…
Introducing “Future Crew”
Do you enjoy playing Space Team, but find that you want tactile controls? Or like the Artemis Bridge Simulator, but think it is too serious? Do you love pushing buttons, turning knobs and shouting at each other? Then you’ll really…
Robot arms: now with inverse kinematics
As a followup to our reverse engineering and configuration of 6DOF PUMA robot arms, we’ve updated our controller source code to have full closed form inverse kinematics support. The math is based on A Geometric Approach in Solving the Inverse…
