NERP tonight: The revolution is over! Let the battles begin!

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

There are a bunch of credit card size and smaller computers out there, but the
one closest to the Raspberry Pi in purpose and features is the Beagle Bone. The
BeagleBone is a credit-card sized Linux computer that connects with the Internet
and runs software such as Android 4.0 and Ubuntu. NERP first saw the Beagle
Board during Drew’s high-level overview in March.

The current Beagle Bone (~$89) costs more than the Raspberry Pi, but the Bone
has better perfomance. Tomorrow, 4/23/13, circutco.com will publicly announce a
new, more powerful, more featureful, and cheaper Beagle Bone. The price for the
new board will put it closer to the Pi. The revolution is over, but the
competiton for the smallest, most powerful, most versatile, and cheapest
embeddable computer has just begun. Adafruit, one of several Beagle Bone
resellers, is getting revved up for the new release.

Tonight Brian Chamberlain will give an in depth introduction to writing code on
the Beagle Bone. Brian’s talk will  “…cover how to setup and run remote
debugging on a BeagleBone from within the Eclipse IDE. It will include a
walkthrough of the key steps for setting things up. Then a demonstration of how
to step through lines of code, inspect variables, and generally cause havoc on a
simple program running remotely on the BeagleBone. Also, as a segway from our
normal RaspberryPi discussions there will be a brief overview of the BeagleBone,
its features, and how it compares to the RaspberryPi.”

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!

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.

Beer Church: March 3rd @ 2PM

Howdy from Beer Church! Just this weekend we put Rhubarb Waves of Grain on tap, and it’s super tasty. Putting the India back in IPA is also quite great, but isn’t yet on tap.

This coming Sunday we plan to brew a simple ale or porter (to be determined!). Suggestions are welcome via our twitter @ps1beerchurch or on the Beer Church mailing list.

To start off, we’ll have a beer tasting featuring any homebrew you bring, both the Cardamom IPA & the Rhubarb mentioned above, and anything from the store you bring too! Tiny beer steins will be provided – please bring a bottle of something if you can.

Once we’ve had a taste, met each other, and talked over the basics of brewing in the process, we’ll move on to brewing a beer. This is just the first day of a weeks long journey that a beer takes from the boil kettle to your mouth, but it’s the most labor intensive and the most interesting to see, so we like to show people this step. Watching a bucket ferment isn’t as fun. Since we’re going for something simple, we’ll probably be done brewing in around 3.5 hours. The ingredients will have been purchased ahead of time, so we’ll get into the brew by around 3PM. The steps include mashing, sparging, boiling, chilling, and pitching. You can lend a hand with most of them, and learn a lot in the process.

Currently in the fermenter are Barely Barley Ale and A Horrible Missake which we’ll be taking a peek at to see if they’re ready to transfer to kegs.

Nitty Gritty

When: Sunday March 3rd, 2PM. We expect to be brewing until around 7 PM or so, but you don’t have to hang around the whole time if you don’t want to. People who help out until the end get a bottle of the beverages they helped with when it’s completed (approximately 1 month later).
Where: Pumping Station: One, 3519 N Elston, Chicago
What: Beer tasting and brewing hands-on
Who: Anyone 21 or over, Pumping Station: One members or not!
Why: Because beer is a worthy purpose for your Sunday afternoon
To Brew: TBD
Brewmaster: TBD

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!

Beer Church Feb 10th @ 1PM: Sake & Mystery Beer

Hello again from Beer Church! Just this weekend we added the flavorings to Rhubarb Waves of Grain. We may keg Putting the India back in IPA this Sunday as well. But before all that, we’ll have a pot luck beer tasting featuring our in-house brews Pumpkin Spiced Ale, Doppelbock, and whatever you bring! Bring something you brewed or something out of the ordinary from a store.

Tucker’s worked out what’s needed to make Sake. So, we’re making Sake this Sunday. That won’t take much time total, so we’re going to do 2 things at once: Barleywine’s also on the ticket. We have Stone Brewing’s recipe for Stone Old Guardian Barley Wine which is a possibility. Other options will be considered day-of unless Eric’s already bought the ingredients for Barley Wine.
