Come celebrate another year of hacking and making at PS: One!

Four years and a month ago a rowdy bunch of hackers and makers moved into what would be Pumping Station: One’s first location. Come celebrate our fourth anniversary in our new space!

When: May 4th, 7PM – Demos and reception; 10PM – Live music!
Where: Pumping Station: One, 3519 N. Elston (near Addison and Kedzie)

We’ll have some of our awesome projects and demonstrations on display for you, so come check them out! We’ll have:

  • Souped-up Power Wheels Racers
  • DIY Quadcopter
  • Check out our new scanning electron microscope
  • Brain-based Jacob’s Ladder
  • WindowFarm
  • THUNDER SLINKY!
  • Other cool things!

It wouldn’t be a real hackerspace party if there wasn’t some good ol’ fashioned hacking going on:

  • Make art with lasers!
  • Silkscreen your own art poster!
  • Learn to solder and walk away with your very own blinkie badge!
  • Print your first object using one of our 3D printers

We’ll have liquid refreshments and some light snacks. Later on we’ll have music and a light up LED birthday cake.

All funds will go to helping us build out our new kitchen area.  Please RSVP and spread the word!

CNC Build Club

Every Thursday night…

The CNC Build Club meets to build, use and learn about CNC machines.

April 18th at 7:00 PM.
Open to non- members

Quantum Delta 3D printer

Over the last three weeks we built this little delta 3D printer.
There are a few little changes to make to it this week, like a spool holder on top.

NERP tonight! Eric Stein: RPi hardware i/o and ZeroMQ

ERP is not exclusively raspberry pi, the small computer and embedded control interest group at Pumping Station:One in Chicago.

Tonight, Eric Stein, who is Chief Cat Herder and president of Pumping Station:One will take time out of his busy schedule to show us a Raspberry Pi and Python based system that sends messages by passing messages.

eric-beer-240
Eric’s system, which is currently in development, receives input from IRC (internet relay chat) and responds by playing an informational message over one of several louudspeakers located around the PS:1 facility. The Pi does text-to-speech conversion on stored messages and i/o logic and control to select the appropriate audio output channel.

A very interesting aspect of the system is the use of ZeroMQ to pass control messages between the Pi and and a server that does something important that Eric will explain. From wikipedia:

“ØMQ (also spelled ZeroMQ, 0MQ or ZMQ) is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker. The library is designed to have a familiar socket-style API.”

Elementary Fourier Analysis, Sunday March 24th at 1PM

Sines, sines, everywhere a sine.

Engraving of Fourier.

This is a Fourier. We will not be analyzing it.

This 2.5 hour class will cover:

  • When and why does the fourier transform ‘work’? (Convergence conditions, etc)
  • What does linear algebra have to do with Fourier analysis? (A lot.)
  • How do we know it works? (Somewhat rigorous derivation)
  • Are there similar concepts/tools worth knowing? (Yes.)

The overarching goal is to demystify the magic formulas
and give a more conceptual grounding in what’s going on.

Recommended background: Calculus II (integration),
trig identities, and basic knowledge of complex numbers, with a
provided cheat sheet and a refresher/intro to those tools at noon.

  • When: Sunday March 24th at 1PM
  • Where: Pumping Station: One Electronics Lab, 3519 N Elston Ave
  • What: Deltas, epsilons, bases, sines.
  • Who: All are welcome, PS:One members or not. Please RSVP to patrick.m.dixon@gmail.com by Saturday so I can make enough handouts.
  • Cost: Free!

Introduction to PS:One: N00bs’ Paradise March 24th at 4pm

Are you interested in learning about PS:One or are generally just new around here?

There’s absolutely nothing wrong with that, and you’re hardly alone.

We’ve decided to create a formal way of teaching curious new folk how the PS:One community works.

Meet with PS:One old-timers (including at least one former president) to learn the many ways to get involved, and the opportunities available to PS:One members, plus hacks for getting around easier.

You’ll learn:

  • the one and only rule you need to remember at PS:One!
  • what mailing lists and IRC channels you should join
  • how to get discounts on classes, tee-shirts, stuff around town, and even monthly dues!
  • how to get certified on equipment
  • how to donate equipment to PS:One
  • how to create a class, event, group, meeting, or what have you
  • how to request a class, event, group, whatever
  • how to blog
  • the wiki.
  • do-ocracy and how to do-ocratize things

The basics:

  • Who: anyone who wants to learn more about PS:One and how it works
  • When: Sunday March 24th, 4 pm until about 6pm
  • Where: PS:One 1st floor lounge
  • Cost: free

Here are the class notes – please feel free to read beforehand (Note: these notes are not a good substitute for class attendance).

NERP tonight with Drew: Beagle Bone and Pi Face

beagle-hd-logo

NERP is not exclusively raspberry pi, the small computer interest group at
Pumping Station:One in Chicago.

Tonight Drew Fustini will demo the Beagle Bone.

BeagleBone (http://beagleboard.org/bone) is an open source, low-cost
credit-card-sized Linux computer that connects with the Internet and runs
software such as Android 4.0 and Ubuntu.

BeagleBone is capable of interfacing to all of your robotics motor
drivers, location or pressure sensors and 2D or 3D cameras. It can also run
OpenCV, OpenNI and other image collection and analysis software.

Through HDMI, VGA or LCD expansion boards, it is capable of decoding and
displaying mutliple video formats utilizing a completely open source software
stack and synchronizing playback over Ethernet or USB with other BeagleBoards.

Drew will also hit the high points of a Raspberry Pi interface board called the
Pi Face (http://pi.cs.man.ac.uk/interface.htm)

Pi-Face Digital is the first of a range of interfaces to allow the Raspberry Pi
to control and manipulate the real world. It allows the Raspberry Pi to read
switches connected to it – a door sensor or pressure pad perhaps, a microswitch
or reed switch, or a hand held button. With appropriate easy to write code, the
Raspberry Pi then drives outputs, powering motors, actuator, LEDs, light bulbs
or anything you can imagine to respond to the inputs.

NERP tonite: Pick-n-Pi

NERP is Not Exlusivey Raspberry Pi, the small computer interest group at Pumping Station:One in Chicago.

gantry-2-640

Boardforge gantry Ver 0.3a in development (Ed_B)

Several members of Pumping Station:One are collaborating on a project to produce a pick and place machine. PnP machines are robotic assembly devices that place electronic components on circuit boards as part of the soldering process. The software that will run the machine is made of several distinct subsystems including motion control and computer vision. Jay Hopkins has been doing some experiments to determine whether a Raspberry Pi can serve as the on-board controller for the machine. Tonight he’ll show nerp some of his progress. Teaser: OpenCV _will_ compile on the Raspberry PI!

NERP is Not Exclusively Raspberry Pi Monday 2/11 @ 7pm

This NERP, Drew Fustini will show us how to WebIDE to program the Raspberry Pi. WebIDE is free from Adafruit. Put simply, “The Raspberry Pi WebIDE is by far the easiest way to run code on your Raspberry Pi. Just connect your Pi to your local network, and log on to the WebIDE in your web browser to edit Python, Ruby, JavaScript, or anything and easily send it over to your Pi.” Drew will use a Pi Plate RGB 16×2 character “Pi Plate” as the output device.

adafruit_LCD_piplate
At the 1/28 NERP, we announced that the Adafruit Industries community grants people intended to send us a care package with Raspberry Pi goodies. The package arrived last week, and rather than opening it right away I thought it would be nice to share the surprise on Monday. It’ll be fun to see what kinds of ideas come out of the box and what kinds of projects they might inspire.

As always, if you have a NERP related project that you’d like to share, bring
it along!

Not Exclusively Raspberry Pi meetup Mon. 1-14-13 7pm

The new year’s first NERP Meetup will be at 7pm tomorrow night.

In the first half hour, we’ll have a beginner’s look at the Raspberry Pi board and software. We’ll see what extra hardware you’ll need to get started with the Pi and how to boot up a new board.

In the second half-hour, we’ll connect a homemade circuit to a Pi and see one method for controlling stuff with Python. You can find out more about NERP at the Meetup page,
