Arduino 301 – Controlling the outside world – March 2014

Workshop 88 is offering a continuation of the Arduino classes featuring a concentration on interfacing the arduino with external devices.  solid state relays, H-bridges and other ways of controlling high voltages sources and motors.

If you already have an arduino, you have all the materials you’ll need for this class.  Otherwise, you can order a kit and we’ll have it for you when you come to the class.

What you need to bring to the class: a laptop with the arduino environment already installed, your arduino, and your breadboard. What you’ll get from the class: an understanding of how to work with the arduino to control higher current and higher voltage DC devices, 110-volt AC devices, and various servos, steppers and motors.

The class was originally scheduled for 2/15/14, but is being rescheduled.  Watch this space!

Using Eagle CAD PCB design Software – March 2014

This class will cover Schematic capture, PCB design, and CAD File generation.

What you should know before coming to this class: You should be somewhat familiar with electronic circuits.

What you should bring with you to the class: You should bring a laptop with the free version of CadSoft Eagle PCB installed and running on it.

What you will leave the class with: After the class you should have the ability to capture a electronic circuit into a schematic, build new components, layout the physical printer circuit board and generate the files needed to have a PCB manufacture make your board.

(This is the first in a series of 4 classes on printed circuit board design and prototyping.)

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.
