NERP tonight: Beagles and Barbells

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

Two Pumping Station:One members, Jarrod Wolf and Gabe Priyev, are co-founders of SpotMe (spotmefit.com), a startup which aims to “Bring Gyms and Health Clubs into the Digital Age”. Spotme’s patented technology

“… makes fitness easy. SpotMe provides workout plans that are tailored to an individual’s goals and that adapt to a user’s biometrics. Our system is seamless; it does not require user input to function. SpotMe service is offered through a subscription that is bundled with gym memberships. When a member shows up at the gym, they are provided with a personalized workout (accessible via app or print out). All a user has to do is put on a wristband and ankleband. It’s that easy.”

Tonight Gabe will describe how the sensing parts work, and the role of small wireless hardware devices that move data between different parts of the system.

Dem Bones

The Beagle Bone embedded computer is in the spotlight again tonight. Drew Fustini will share some of the BB-related insights he gathered a couple of weeks ago at Design West. This will be the first in a series of talks Drew will give on “official” guidance for new users as offered by the Beagle Bone developers and project evangelists. Good stuff.

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.

beagle-hd-logo

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.

http://www.adafruit.com/products/1278

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.

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!
