Gresham Library Computer Lab

With conversational lectures and hands-on labs, students will learn HTML and CSS required to build a static website.

This is a class for beginners to coding, but students must feel comfortable using a mouse and keyboard and have basic experience using a computer.

Presented by PDX Code Guild

With interactive lectures and hands-on Python labs, students will gain the basic tools and skills, giving you a solid foundation for further learning. This class covers setting up your environment, all of the programming data types, functional programming, and more!

EAST Knowledge is pleased to announce it's fourth meeting. Pat Nystrom will be giving demonstrations on his efforts to make it easier to prototype electronics at home. All are welcome!

• What: The Evolution of Hardware Design in the Home Lab
• Who: Pat Nystrom
• Where: The Computer Lab at the Gresham Library
• When: 10:30am - Noon, Saturday, February 14, 2015
• Why: Sharing what we know

Pat Nystrom led off our EAST Knowledge series a little over a year ago, and we wanted to bring him back to see what he's been working on. He will be talking about and demonstrating two topics:

• A dry-film soldermask process which makes home-made circuit boards much friendlier to use
• An update on the development of his manual pick-place machine

Come and learn something new!

Solder masks are used in electronics manufacturing both to protect copper traces and to keep solder from going where it shouldn't.

Pick and place machines are devices used in electronics manufacturing. They come in various sizes, but they are commonly expensive. Pat is working on something that would be suitable and affordable for enthusiasts or prototype manufacturing.

This is EAST Knowledge's third meeting. All our welcome. We look forward to seeing you there!

• What: Introduction to IPython Notebook
• Who: Charles Stanhope
• Where: The Computer Lab at the Gresham Library
• When: 10:30am-Noon, Saturday, June 14, 2014
• Why: Sharing what we know

Come and learn about IPython Notebook interactive computing environment! An open source project used and developed by a community of scientists and engineers, IPython Notebook is a powerful tool that can save time and effort, and allows you to:

• Rapidly prototype and explore algorithmic ideas
• Easily share results
• Replicate work
• Freely collaborate
• Leverage a large body of existing libraries

Charles will introduce and demonstrate IPython Notebook. He hopes to have a live system that can be used by the audience. All you will need is WiFi, a web browser, and some curiosity. So bring a laptop!

This is EAST Knowledge's second meeting. All our welcome. We look forward to seeing you there!

• What: Don't Touch That Data!
• Who: Jim Rulla
• Where: The Computer Lab at the Gresham Library
• When: 10:30am-Noon, Saturday, March 8, 2014
• Why: Sharing what we know

There's a serious problem: the hardware is spewing out data, but the answer is wrong. It's too late to redesign, and besides, the product ought to work. Another filter and some ad hoc software will have to suffice — until new problems arise.

Sound familiar? If the textbook analysis doesn't apply to your problem, no filter and no software hack will help. The only reliable way to fix the problem is to model it correctly, then solve the model problem.

I will show how incorrect modeling sets back — and in some cases, destroys — product development. The examples:

• are real,
• are simple (when solved correctly), and
• illustrate techniques you can apply to your projects.

The examples include applications from audio, optical, and communications engineering.

The right model is almost always simpler to understand and easier to solve than the wrong models. Come see how you can simplify your project!

EAST Knowledge invites you to attend our first meeting!

• What: Pick and Place Machine for the Tech Enthusiast
• Who: Pat Nystrom
• Where: The Computer Lab at the Gresham Library
• When: 10:00am-Noon, Saturday, January 11, 2014
• Why: Sharing what we know

Pat will talk about and demonstrate his pick and place machine. It’s a self-funded project that is still in progress, but there’s plenty to show and talk about. Pat will also be interested in feedback and ideas.
