PDP-11/34 cabinets

We rescued two PDP-11/34 computers and their associated equipment from a storage unit in the Bronx and have been working on getting them running again. The computing system included multiple RK05 hard drives, two RL02 decpack drives, a TU11 tape drive and tons of media, including “digitized monkey brains“. Read on for more details and the exciting boot sequence.

Emma-O judges your cloud infrastructure.

Every now and then, a particularly hard storm hits an undisclosed datacenter in Virginia where a huge chunk of The Cloud faces off with actual clouds to see which one can keep electricity running through it the longest. Sometimes the data center loses, causing DevOps teams and assorted other developers to get calls and tweets from literally everyone telling them their site is down.

Usually this sort of apocalypse is indicated with a tiny icon on a web dashboard, visible only to the people already panicking and frantically reading up on High Availability and Multi-AZ Deployments. A little red icon doesn’t quite convey the gravity of the sky falling, so I figured the best indicator of cloud infrastructure status would be the Buddhist king and judge of hell, Emma-O (aka Enma-O aka Yama). I happened to have a scan of an Emma-O wood sculpture from a previous project at the museum I work at (btw we’re hiring), so I scaled it up a bit and printed a copy in transparent blue-ish PLA.

A quick word of warning for those coming to Laser Night tonight: our laser is having some power issues and is not operating at 100%. We’re working to fix the issue as quickly as we can, but we probably can’t cut anything thicker than a couple of millimeters at present. We’ll sing out once everything’s up and running again!

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!
