Coffee Break #5
| What: | Coffee Break |
| Where: | Cafe Delirium |
| 308 N Main Ave, Gresham (map) | |
| When: | 10:00am - Noon, Saturday, November 21st, 2015 |
| Why: | Sharing what we know over good coffee |
We had a great meeting last month. For this month, we invite you to join us for coffee at Cafe Delirium. If you haven't made it to one of our talks, the coffee breaks provide a nice opportunity to drop by and introduce yourself. We have the room in the back reserved. We're going to hang out for a couple of hours, so feel free to come by, talk shop, show off what you're working on, ask questions and pick each other's brains. We look forward to seeing you there! All are welcome!

Meeting #6
Going Back in Time for Some Vintage Howdunit
| What: | Going Back in Time for Some Vintage Howdunit |
| Who: | Bill Howland |
| Where: | The Meeting Room at the Gresham Library |
| 385 NW Miller Ave, Gresham (map) | |
| When: | 10:30am - Noon, Saturday, October 24th, 2015 |
| Why: | Sharing what we know |
Bill Howland will re-introduce us to vacuum tubes and their uses. He will:
- Give a summary of the origins of vacuum and gas diodes and related thermionic devices
- Have show-n-tell demonstrations of the earliest and simplest of such devices: The diode
Come and learn something old!
Vacuum tube diodes were put to use in the early days of radio as "detectors", because they were more robust and reliable than crystal, mechanical, and chemical contrivances used for this purpose. With further development, thermionic vacuum and gas diodes advanced to be capable of power rectification with ever greater efficiencies.
Many example devices from the 1930's to 1950's will be available to examine. There will be orange, purple, and blue glows in the demonstrations!
Bill shares some of his projects on his blog: Evil Science Audio

Meeting #5
Locating Intrusions Using Fiber Optics
| What: | Locating Intrusions Using Fiber Optics |
| Who: | Jim Rulla |
| Where: | The Story Room at the Gresham Library |
| 385 NW Miller Ave, Gresham (map) | |
| When: | 10:30am - Noon, Saturday, April 18th, 2015 |
| Why: | Sharing what we know |
Interferometers measure distances to within fractions of the wavelength of light. Put a couple of these incredibly sensitive devices on the fence around an airport, and you can not merely detect a would-be intruder — you can locate him. Put a pair on a pipeline, and you can not merely detect nearby digging that could damage the pipe — you can locate its source. You might even be able to detect — and perhaps even locate — leaks in the pipe.
The detection and location mechanisms are fascinating examples of clever engineering. I'll explain how these patented systems work and illustrate new algorithms that improve performance.

Meeting #4
The Evolution of Hardware Design in the Home Lab
| What: | The Evolution of Hardware Design in the Home Lab |
| Who: | Pat Nystrom |
| Where: | The Computer Lab at the Gresham Library (map) |
| When: | 10:30am - Noon, Saturday, February 14th, 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
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.

EAST Knowledge would like to do something a little more relaxed for our next meeting. We invite you to join us for coffee and pastries. We're going to hang out for a couple of hours, so feel free to come by, talk shop, show off what you're working on, ask questions and pick each other's brains. We look forward to seeing you there!

Meeting #2
Don't Touch That Data!
| What: | Don't Touch That Data! |
| Who: | Jim Rulla |
| Where: | The Computer Lab at the Gresham Library (map) |
| 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!

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.
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.
