The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

Giant Coil Sculpture at Hyde Park Art Center

 

Coil-in-Shop

You may have seen me (with amazing help from Madeleine Klichowski, Dan Locks, Matt Triano, and Pipefitter Dave) hard at work on some very curious looking objects (like a giant coil) in the shop and electronics lab. Well, finally, we’re done– it’s new kinetic sculpture and it’s now installed at the Hyde Park Art Center, for a group show opening Saturday, Aug 10, with a reception from 3-5pm.

2013-08-06 11.02.25 Red Ball Install

 

The show will also feature a 10 foot wide version of Red Rubber Bands (pictured below in smaller form). The new version looks AWESOME (and I’ll be sharing photos as soon as I get them).

RRB 1697 opp

Even more fun, Maker Camp interviewed me about the sculptures this week. (Also participating, circuit bender Patrick McCarthy.)

YouTube Preview Image

So, if you’re around Hyde Park tomorrow, please stop by the reception from 3-5pm. Or come check it out any time during normal gallery hours til September 21, when we’ll close the show with a public critique.

(If you’d like more info on my sculpture, check out my website.)

Cheers!

NERP Tonight: QT and Steppers

NERP Tonight: QT and Steppers

 

Tonight at NERP, we’ll have a show and tell about the PS:1 entry in the Element14 hackerspace challenge.(http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/06/12/beaglebone-black–the-2013-hackerspace-challenge/)We’ll highlight use of the QT framework and gui tools on the Beagle Bone Black to run the stepper motors on the pick and place machine. There are always challenges in getting a new platform up. One challenge has been resolving version problems with the QT3 to QT4 transition on ARM. We’ll find out how that’s going. Also we’ll also have a tour of the system’s Z- and θ- axes mechanism and find out what the test results were on using some very small stepper motors to drive the head. As a bit of improvisational comedy, some of the tests will be done live during NERP! Yow!

NERP: Retro DOS Gaming on the Raspberry Pi, and a Hackerspace Challenge Update

Tonight at NERP,  Jay Hopkins will show us some how to set up an MSDOS emulator and use it to run 8-bit games. Bleep.

Ed will talk about the status of PS:1’s project for the Element14 Hackerspace challenge. While amusing, entertaining, and informative, the update will also be a pitch for anyone who is interested in the technologies to help PS:1 compete for the big prize.

Programming in Erlang -plus- Making an Xbox Media Center on the Raspberry Pi

Tonight at NERP, we’ll have two presentations.

Brian Chamberlan will tell us about using Erlang to program/control the RaspberryPI/BeagleBone. Erlang is a functional, general-purpose concurrent, programming language and runtime system. Erlang provides language-level features for creating and managing processes with the aim of simplifying concurrent programming. Processes communicate using message passing instead of shared variables, which removes the need for locks. [paraphrased from wikipedia]

Michael Beck will show us how to set up Xbox Media Center, XBMC on the Raspberry Pi. Pretty much every possible mode of interacting with a digital media stream is supported by XBMC. The Raspberry Pi’s excellent (but proprietary) video rendering hardware makes it an ideal platform for building a home media center.

Raspberry Pi Video Camera, BoneScript on the Beagle

Raspberry Pi Video Camera, BoneScript on the Beagle
NERP is not exclusively raspberry pi, the small computer interest group atPumping Station:One in Chicago.

We’ve been wondering what it’s like to work with the new Raspberry Pi camera module. Tonight we’re in luck. Craig LeMoyne has a Raspberry Pi project he’ll show us tonight. In his words:

“I have an RPi Model A in my basement running Apache2 and taking pictures
using the new Camera Module every few seconds of a wet area that I *hopefully* managed to patch. It is good fun, and I can also do timelapse video from the pictures. The Pi will even compile the timelapse for me!”

Drew Fustini will introduce us to programming the Beagle Bone Black in BoneScript.
I’ve been saying for years that Javascript would be the next hot language for microcontrollers – maybe it’s true. From beagleboard.org/Support/BoneScript

“BoneScript is a node.js-based language specifically optimized for the Beagle family and featuring familiar Arduino function calls, exported to the browser. Get started exploring the BoneScript Library to discover the great simplicity that is made possible by utilizing Linux in BoneScript.”

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.”
