Linux Charcuterie – How the Linux Sausage is Made

Ian McLeod will take a look at the entire chain of building a distribution from start to finish, exploring how source is packaged and built, and then complex combinations of packages are joined together to make a cohesive Linux distribution. His talk will include include details of how this all works in a diverse set of environments – from aging x86 hardware to public cloud environments, Linux containers, and immutable systems.

Fedora and Project Atomic

Sten Turpin will build on Ian’s talk, giving an overview of Red Hat’s new, container-focused platform, Project Atomic. Basing his talk around the Fedora-based version of the project, he’ll demonstrate how to deploy and use Project Atomic on the Amazon AWS infrastructure.

Foodstuffs

We will have food! Probably pizza! At least a few of us typically bring some beverage to share, as well. We’re a community-run organization, so we recommend bringing a few dollars if you’d like to partake of the food. No one will be denied a slice of tasty pizza for inability to chip-in, though.

Here is the event on Meetup.com:

NERP Tonite! A Red Pitaya (And a special request.)

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.
Tonight at NERP, Drew Fustini will introduce us to a brand new, small single board Linux computer. The Red Pitaya is so different from, say a Raspberry Pi that comparing the two would be like comparing, well, raspberries and pitayas. The Red Pitaya (pitaya is also known as dragon fruit) does high speed high quality data acqusition and control with several kinds of i/o. Scientists and engineers can use the Red Pitaya to build custom hardware and virtual instrumentation interfaces for precise measurement and control applications. The ADC/DAC’s are very fast compared normal embedded systems. The processor configuration is also different from normal RPi class systems. To give an idea of just how different the Red Pitaya is from an RPi, the Red Pitaya’s Hello World program is a Digital Storage Oscilloscope. Drew will show us how  to get signals of various types into and out of the Red Pitaya, and some examples of time and frequency analysis can work in virtual instrumentation. Delicious. Also, Drew does Really nice slides! https://plus.google.com/photos/+DrewFustini/albums/6126873248127580209?banner=pwa

Speaking of analog — Tonight we’ll have a brief diversion into the land of discrete analog electronics. The Colpitts oscillator is an alternative to Direct Digital Synthesis for producing sine waves in the RF spectrum. Joe Talafous has been working with the Colpitts circuit, and he will show us how to get RF out of a few cheap components. I like to remember that Electronics for the DIY’er used to be “hard” before the advent of Arduino shields. Facetiously it might be said that analog RF is _real_ electronics.

A special request for a worthy cause: Cathleen Doyle (cdoyle at northbrook dot info) tells us that the Northbrook Public Library will be running a whole month of programs this June highlighting maker/diy activities. They’re hoping to find someone who could give an awesome, introductory lecture/demonstration on the many uses of Raspberry Pi’s and how they work. Would there be anyone PS:One could recommend and who would be willing? We do pay!

Let’s Drink and Learn About: Sangiovese

IMG_2993

Italian Chianti – Chianti wine always either mostly or entirely made of Sangiovese

IMG_2992

Italian Sangiovese from outside Chianti – Over 10% of Italy’s total wine production is Sangiovese

For the fourth installment of our monthly adult beverage appreciation event, “Let’s Drink and Learn About…”, we did a tasting of several different Sangiovese wines.  If you missed it, feel free to peruse our class notes!

Our next session will cover red Bordeaux, and its 5 constituent grapes (Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot, and Malbec).  This will be a joint event with South Side Hackerspace: Chicago, and will be hosted in their space (2233 S Throop St #214).  As per usual, it will be on the 3rd Friday (March 20th), and will begin at 7 PM.  There is no cost to attend the event, but please bring a bottle of wine (Cabernet Sauvignon or Merlot, please) to contribute to the tasting.  You can find more info, or RSVP for the event, on our Meetup!

CNC Build Club – 2/5/2015 7:00pm

This month’s CNC Build Club meeting will be a demo night.  Bring something to show.  It can be a project you finished, something you made, a work in process or something we might think is cool.

I will be bringing several things I have recently completed.

The bipolar ORD Bot: This is a CNC machine I built for 2015 ORD Camp.  It is a super simple drawing machine with some fun math behind the motion.

The DC Power Supply Interface: This is something I did for Inventables that we will be selling soon.   It really cleans up the wiring when you use a DC power supply on a CNC machine.

The TB6600 Stepper Driver Shield:  This is another Inventables project.  The TB6600 can do a ton of cool CNC stuff.  Now you can interface it to the free grbl CNC controller.

The CNC Club is a monthly meeting of Chicago area people passionate about learning, building and using digital fabrication equipment.  It is held at the Pumping Station One Hackerspace.  It is open to non members.  We also have a Google Group called CNC Build Club.

Each meeting we talk about, build, train on and use CNC machines.  We have 3D printers, laser cutters, CNC routers and vinyl cutters.  Come out and join the fun.

Please RSVP on Meetup.  I will have a CNC or Inventables related door prize to a random person who RSVPs and is present at the meeting.
