The adventure continues! We had a great turn out at the last ShapeOko build event. Now it’s time to assemble the gantries and do some wiring. Join us this Wednesday July 30 from 7-10PM in PS:One’s shop to see the machine really take shape, and maybe we’ll get to see it move, too. Learn about open hardware and the ShapeOko 3D carving machine. This event is open to the public and is great for newbies and experienced CNC’ers, too.

You are all invited to an exciting night of gambling-free poker!
Players of all skill levels are welcome! We will be playing Texas Hold ‘Em to raise money for the Noise-o-tron kits we will be teaching people how to build at the South Side Mini Maker Faire this Saturday. We provide this demo for free to Maker Faire attendees, and we’d like to keep it that way so we can help educate as many people as possible! Food will be provided; feel free to bring your own drinks.
So how does the gambling-free part work? The entry fee for playing at a table is $10, and you’ll get a stack of chips to play with. When you are done playing, you turn in your chips for raffle tickets. Each dollar in chips that you have will convert to 1 raffle ticket. At the end of the night, we will have a raffle for 1st and 2nd prizes. Don’t worry, you do -not- have to be present at the raffle drawing to win. As long as you’ve turned in your chips, you have a chance of winning. We will notify the winners via email, and you will get your prize ASAP. What prizes do we offer? You’ll just have to wait and find out! We promise that you’ll like them.
Also: We are looking for a third dealer. Justin and I will be dealing all night, but we would really appreciate it if someone would volunteer to help us deal another table.
Rules & strategy links for Texas Hold ‘Em
We will also have printouts of the rules at each table for reference. We look forward to seeing you there!
Where: Electronics Lab
When: Friday August 1st, 19:00-24:00; the raffle drawing will happen at midnight.
Come out to see the recently premiered documentary about the life and struggles of Aaron Swartz, Reddit co-founder and political activist.
“Swartz was involved in the development of the web feed format RSS, the organization Creative Commons, the website framework web.py and the social news site, Reddit, in which he became a partner after its merger with his company, Infogami.[i]
Swartz’s work also focused on sociology, civic awareness and activism. He helped launch the Progressive Change Campaign Committee in 2009 to learn more about effective online activism. In 2010 he became a research fellow at Harvard University‘s Safra Research Lab on Institutional Corruption, directed by Lawrence Lessig. He founded the online group Demand Progress, known for its campaign against the Stop Online Piracy Act.”
There will be popcorn provided, and feel free to bring any snacks or drinks of your own. After the documentary showing there will be discussion, or people can hang out. This is a public event, so bring your friends!

The event was a big success with over 30 people showing up to hear Tim answer questions about IBM’s Watson. Here are some pictures and sample questions (may be heavily paraphrased since they are drawn from my shoddy notes and memory) from the event:
Q: Can Watson pass the Turing Test?
A: Watson has never been given the Turing Test.
Q: Are there plans to build a physical analogue for Watson? (Asked multiple times)
Q: Can you tell us about the specific details of what you do?
A: No, but after Watson was on Jeopardy IBM released detailed documentation
Q: Has anyone fed Watson info about itself?
Q: There seems to be a competition between IBM and Google in the realm of AI. Do you believe that the future will include more mainframe-based AI’s like Watson or decentralized neural network based AI?
A: I’m a big fan of decentralized neural networks.
Q: How do you go about getting a job in AI?
A: I have a CS degree with an AI concentration, and I got an internship with IBM that eventually led to working on Watson. I worked on unrelated projects before this. There’s no set path.
Q: Is there any project to work on improving Watson’s ability to interpret history?
A: There are many NLP (natural language processing) projects that focus on solving that problem.
Q: Does one version of Watson know what other versions of Watson know? (i.e. medical student Watson vs cognitive cooking Watson)
Q: Why is Watson so much better than Siri?
A: Siri is not really an AI aside from its NLP abilities.
Q: What question do you wish people would ask about Watson?
A: You guys ask good questions.
Q: Do you do unit tests and end tests on Watson?
Q: Are there any Easter eggs in Watson?
A: I can’t tell you.
Q: Do you have a button that stops Watson if it turns into HAL?
A: We’ve had no serious thoughts of Watson turning on people.
Q: Watson does not have ontological understanding of the world; any benefit to adding that?
A: We’re working on it.
Here are some related links to the Q&A that Tim shared afterwards:
1.) “Here’s the IBM research journal issue on Watson, that gives away all the tech secrets anyone would want”: http://ieeexplore.ieee.org/xpl/tocresult.jsp?reload=true&isnumber=6177717
2.) Behind a paywall:( “Computational creativity for culinary recipes”: http://dl.acm.org/citation.cfm?doid=2559206.2574794
3.) “This is relevant to cognitive cooking, Florian Pinel is one of the authors, he’s our team lead”: http://arxiv.org/abs/1311.1213
Curious about computer numerical control and open hardware?
Want to meet and help build PS:One’s newest machine? Join us
for a group build of an upgraded ShapeOko 2 CNC router,
donated by Inventables! Everyone is welcome, newbies and
experienced alike – if you can tighten a bolt, you can
assemble a ShapeOko. Please RSVP to the Meetup group or cahira_mirrored [at] yahoo [dot] com, so we
have some idea how many people to expect.
Wednesday, July 16th
Everyone is welcome, although only members will be authorized (at a later date) on the machine once it’s completed.
Hackers frequently need to solve geometric problems for their projects. Whether it’s cutting acrylic on a laser cutter, slicing wood on a table saw, planning the route of a robotic arm on a new 3D printer, or analyzing a polygon mesh in a Python script, a working knowledge of geometry can save time, frustration, and material costs.
This isn’t the geometry you learned in high school, though. This is a crash course in the basic notions of linear algebra, perhaps the most useful branch of mathematics there is.
This course is geared towards demonstrating practical concepts and applications that can be put to use immediately in your own projects. To avoid bogging down the class with tedious details, we will use our computers to perform the calculations for us, allowing us to focus on the big picture and core ideas of each technique we cover.
The only prerequisite for the course is a solid understanding of high school algebra. Exposure to vectors and matrices would be helpful, but not required. There will be a review session before the class officially begins for anyone who wants to brush up on the basics.
Topics for the class:
- A Review of Coordinates, Vectors, Matrices
- Examples of Linear and Affine transformations
- Linearity, Bases, and Where Matrices Come From?
- Square Matrices, Determinants, and Inverses
- Application: Solving Systems of Linear Equations with Gaussian Elimination
- Dot Products, Angles, and Lengths
- Cross Products, the Plane Equation, the Normal to a Plane
- Application: the Line-Plane Intersection Test
- Triangles and Baricentric Coordinates
- Application: the Line-Triangle Intersection Test
- This event is open to the public
- Prerequisite: High school algebra, some light exposure to vectors and matrices
- When: Sunday July 20th at 5pm, review session starts at 4:30pm.
- Where: 3519 N. Elston – 2nd Floor in the Electronics Lab
- Cost: Free
NERP is Not Exclusively Raspberry Pi, the small computer and
embedded systems interest group at Pumping Station:One in
Chicago. NERP meets every other Monday at 7pm at Pumping
Station:One, 3519 N. Elston Ave. in Chicago.
Luciano Ramalho is a member of Garoa Hacker Clube in Sao Paulo,
Tonight at NERP, Luciano will tell us about the Pingo
project in progress at Garoa HC
(http://www.pingo.io/docs/intro.html). Pingo aims to make
interconnecting small controllers of all sorts easy and
transparent, so that they can use each other’s peripherals. An
example use case would be using Python on a Beagle (or similar)
to effectively “program” one or more attached Arduinos.
From the website:
“Pingo provides a uniform API to program devices like the
Raspberry Pi, BeagleBone Black, pcDuino etc. just like the
Python DBAPI provides an uniform API for database programming in
The API is object-oriented but easy to use: a board is an
instance of a Board subclass. Every board has a dictionary
called pins which lists all GPIO pins on the board. Each pin is
an instance of a Pin subclass with attributes that you can
inspect to learn about its capabilities.”
Find NERP and Pumping Station:One
Doors open at 6:30pm. The next meeting is July 7th, 2014.
NERP is free and open to the public.

What will you do with Watson:
Watson processes unformatted data, i.e. natural language documents, and not structured databases, so part of Tim’s job is to work on ingesting that data and making sense of it. One of his current projects is cognitive cooking, in which Watson comes up with recipes for us to cook and is really awesome:)
Cognitive Cooking in the IBM Cloud:
So come with any and all questions about one of the most famous robots in the world:)
When: Monday July 7, 2014 7-8 PM

Hey everyone! We’re starting a new robotics group tonight at 19:00. SIGBOT is the Special Interest Group for Robotics. We’ll be meeting the 3rd Thursday of the month in the electronics lab at Pumping Station: One.
Tonight we’ll be talking about what this club will really be all about. I want to hear everyone’s ideas for projects we can work on as a group, and also what projects people are working on individually.
Hope to see you all there!
