Things this week:  

1.   Is your computer just sitting there idle?

 

If you leave your computer on when you are not using it, there are ways you
can put your computer to use it can do scientific research, backup your
data, and even look for signs of extraterrestrial life. Searching for
extra-terrestrial life or building protein molecules from the comfort of
home. 

 

Brian, N8UDG, and Steve, KB8STB, will talk about several of the these
projects and tell you how your idle computers help advance scientific
research.

 

Next week : 4/30/20  GPS: Beyond the Basics by John Ackermann, N8UR

There is a lot more capability in the GNSS (Global Navigation Satellite
System) than what is provided by typical consumer GPS units. It's possible
to locate with precision of a few millimeters. In the last year, GNSS
modules capable of results like this have become available for less than
$200.

 

This presentation explains how the GNSS system works to provide these
capabilities, and shows some of the results obtainable.

 

2. Projects

Keep working on your projects at home.  At last night's DARA board meeting
it was discussed that they MAY be doing a Zoom meeting with you showing off
your projects.

3. License Exam Questions of the week

One question is drawn from each of the three question pools. Steve, AE8AT,
is providing these questions.  Thanks Steve
