New online discussion group – linux device drivers

So that we can all learn about Linux Device Drivers, we have set up a Workshop 88 Google Group here:

https://groups.google.com/forum/#!forum/workshop88linuxdrivers

…to discuss this book:

http://lwn.net/Kernel/LDD3/

The 1st post is a bullet list of chapter 1’s main points.  Feel free to join in and comment about such things as “mechanism” and “policy”.

In chapter 2, there will be some code examples to try.

It would also be fun to speculate where we can go with this.  One thought is to create a WS88 project (maybe even a PCB) that provides a new physical computer interface. Like a capacitive-touch-slider to control features such as volume.

Programming a Tiny85 with Arduino – January 2014

Tiny85: a simple, cheap alternative to dedicating an Arduino to a long-term projectATtiny85 - Image credit: Atmel Atmel offers several processor chips in the same family as the Arduino’s ATMega328P that are often perfect for a simple permanent controller. This class introduces you to the ATTiny85, with mention of some others. You’ll leave with an ’85 running a simple blinkie with code you wrote, you ported to Tiny85, and you burned into the ’85 along with a mini shield to use an Arduino as a programmer for the ’85 and many other Atmel chips. The class is open to Arduino users with at least basic programming skills. (You’ll need to be able to modify the Blink sketch.) You’ll need to bring a working Arduino (or clone), a laptop with the Arduino 1.0.4 development environment, and a breadboard. We’ll supply a Tiny85.

Update 1/28/14:  The class went quite well.  Jim wrote up some notes on it including links to the slides and class handout here.

Mastering the Linux Command Line – February 2014

Linux gives us the power we need to crush those who oppose  us.  Learn how to being to use the hundreds of tiny utilities contained  in *nix systems to create simple solutions that you may think require writing a program, script, or complex system. Forget spending countless hours designing, writing ,and debugging code in the cloud. See the methods taught in this class to begin to understand how to quickly link Linux commands together to create quick solutions to what may seem like a complex task.  Spend more time on world domination and less time learning the sexy programming language of the day. What you will learn:

  • Learn to navigate the shell quickly saving keystrokes, sparing yourself from the scourge of carpal tunnel syndrome.
  • What the hell do all those funky symbols mean? Amaze your significant other with the ability to read shell scripts like a Chinese newspaper.
  • Learn a few quick tips to automate your system administration and audit it for weaknesses.
  • Create a simple command to notify yourself of changes to your favorite web pages.  Never miss out on those Deltron 3030 tickets again!
  • Create parsers to crunch the data needed to map pig genomes.  Win the Nobel prize!!
  • Stand up a poor man’s web server to serve content in a pinch.

We’ll only touch the tip of the iceberg but you’ll walk away with the understanding and methodology to search the UNIX tool set to create your very own solutions to life’s problems. What you should know ahead of time: Basic Linux commands and how to navigate the file system: Are cd, rm, mv, cp man, and ~  Greek to you?  Learn this first at home: http://code.google.com/edu/tools101/linux/basics.html What you need to bring: A laptop running your favorite flavor of Linux or vm-ware player.  The utilities we will review are available on 90% of *nix flavor system.  You can also download Linux appliances, but please come to class with your system ready.

Hackers in the Pub – March 2014

We’re bringing back the “Hackers in the Pub” event for Workshop 88!  We’ll be meeting up at the Tap House Grill in Downtown Glen Ellyn. After some drinks and chatting at the pub we’ll walk down to the Workshop which is only two blocks away! Be sure to bring your latest (small) project, or if it’s too big, just your enthusiasm for it. 😉

Introduction to Arduino class (Arduino 101) Saturday January 18, 2014

Workshop 88 is offering our introduction to the Arduino platform at our makerspace in Glen Ellyn. This class is for anyone (member or non-member) who wants to learn how to get started with the arduino microcontroller, regardless of experience with programming or electronics. Class attendees will learn how to configure their arduino programming environment, how to design simple circuits for interfacing with the arduino and how to write simple programs to control the arduino. What is Arduino, you ask? From their home page:

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

If you need to get an arduino, please see the Workshop 88 Arduino Store. Sales from that store are fulfilled by amazon.com, and help support Workshop 88. Alternatively, you can order Arduino systems from several places, including Adafruit and Sparkfun. Both companies have lots of tutorials and howtos to get you started with Arduinos. If you’re looking for a local source to get Arduinos, try Trossen Robotics.

What you’ll get from this class: If you choose the registration + materials option, we will have an arduino and assortment of electronics components for you to take home after the class. (The Workshop 88 Arduino Store is by far a cheaper route to get supplies.)

In this class you will learn how to start programming in the Arduino environment including interacting with the inputs and outputs of the Arduino.You should bring: a laptop with the Arduino environment downloaded and installed.  Please contact us (info@workshop88.com) if you have any questions.Image credit: By Linuswiki (Own work) [Public domain], via Wikimedia Commons

Electronics shop remodel

Two of our members, Paul and Eric, recently took initiative to rework the electronics lab. The lab has already seen quite a bit of traffic in less than two weeks of being operational. Big thanks to Paul and Eric for all of their hard work and the materials that they provided for this remodel of one of the most important rooms at Workshop 88!

Workshop 88 co-founders Jay Margalus and Russ Lankenau recently gave a talk titled “Open Hardware and the Future of Games”. In their presentation they talk about a lot of things including Workshop 88, Raspberry Pi, open hardware initiatives, games as culture and much more. It’s always awesome to see what has come out of the work done by Workshop 88 members!

Russ is the current president of Workshop 88. He and Jay run an independent game company called Lunar Giant as well as a coworking space in Mokena, IL called SpaceLab.
