HacDC

Tayeb Zaidi will introduce the world of Software-Defined Radio (SDR) at an online workshop to be held on Wednesday, August 26. Tayeb will walk participants through the most common open-source SDR tool, GNU Radio, and then demonstrate an actual hardware setup to broadcast FM radio signals. Go to our Meetup site for more details and information on how to participate.

St. Stephens Episcopal Church, where HacDC’s facility is located, has been shut down due to Covid-19. All tenants, including HacDC, have been told not to use the facility until further notice. We will post a notice here and on MeetUp when our activities resume.

All About Circuits is a comprehensive electronics industry website featuring a free six-volume online textbook about electronic circuits. Volume Six is devoted to projects and experiments, tied closely to the material in the preceding volumes. HacDC members have begun a joint seminar project to work through these projects in HacDC’s workspace, one by one, in the order they appear in the text. Anyone interested in participating in these learn-by-doing exercises is welcome to join in.

We have now complete the first chapter, on “Basic Concepts and Test Equipment.” Future sessions are suspended until the Covid-19 emergency has passed. On the first Monday after the emergency ends, we will move boldly on to on to “Series Batteries,” “Parallel Batteries,” and time permitting our first “Voltage Divider.” Though not required, you will get more out of the session if you can read the “Batteries and Power Systems” sections from Volume 1 in advance.

The session will run from 7:00-8:30pm. If we don’t finish the experiments mentioned here, we will pick up where we left off the following week.

Parts and equipment to complete at least one copy of each experiment will be provided at the space. If you would like to bring your own multimeter, batteries or other equipment you are welcome to do so.
