Maker Faire 2015 Recap – Part 2   Leave a comment

Since pictures are worth a thousand words, here is a 2015 Bay Area Maker Faire recap in images from and around our Not Your Grandpa’s Ham Radio theme booth.

The Bay Area Maker Faire 2015 team: Team Leader Brian Yee W6BY and his wife Pat and daughter Stephanie, Dennis Kidder W6DQ, Lisa Gibbons KF6QNG and Paul Zander AA6PZ

We had working, hands-on ham radio projects including Brian’s (W6BY) 10 GHz ham radio transverter system, a radio-controlled tractor/forklift (ZigBee controller) and the big screen used as an electronic sign.

Dennis W6DQ brought several brand new projects this year, including a working Amateur Radio broadband (WiFi) network with seven nodes, a software-defined radio (SDR) system.

I brought a demonstration comparing old and new technology in antenna tuners. It uses light bulbs for a substitute (“dummy”) antenna.

 

 

There’s so much to see and do. Here are some pictures of what I get a chance to see.

 

Always great to see Tenaya promoting Arduino and Arduino related projects and products!

Maker Faire Bay Area 2015: Recap Part 1   Leave a comment

Maker Faire Bay Area 2015 T-Shirts for Makers

Maker Faire Bay Area 2015 T-Shirts for Makers

Maker Faire Bay Area is now history. Our booth, “Not Your Grandpa’s Ham Radio” included new projects and demonstrations. This was our fourth year as Makers and the fifth year as visitors to the Maker Faire in San Mateo.

This is a short overview of our display. Stay tuned for more images, stories and videos.

Here is the text from our handout. It answers some of our most-often asked questions:

What are we doing?
Thank you for your interest in our Maker Faire display “Not Your Grandpa’s Ham Radio.” This is our fourth consecutive year as “Makers,” and our goal is to show people what today’s ham radio operators are doing with the newest technology.

Who are we?
We are licensed Amateur radio operators (“hams”).

Is this like CB?
Yes and no. Ham radio is similar in that we use two-way radios and antennas to talk with each other, but hams can communicate using Morse code and computers in addition to voice, and we even have our own satellites. Ham radio requires a license issued by the Federal Communications Commission (FCC) in the US and licensees are required to pass a written test on electronics theory, radio regulations and operating procedures.

How far can you talk?
We can communicate with other ham stations around the corner or across the globe, depending on a variety of factors that affect the way radio waves travel. The equipment we are using operates on frequencies that generally follow line-of-sight paths. However, hams have discovered that signals can be reflected against objects such as buildings, trees, islands and mountains to extend the range. Using these techniques, we are able to contact other stations hundreds of miles away.

What kind of radios are you using?
We are builders and experimenters in microwave radio communications. No commercially-built, “off-the-shelf” equipment for these frequencies exists, so we must build our own equipment, or modify commercially-made equipment meant for other communications services, such as satellite TV, cell phone and long-distance telephone.

How much does this equipment cost?
Like any other hobby, people spend as much or as little as they can afford. Most people involved in ham radio spend as much as any serious stereo enthusiast, amateur photographer or woodworker.

Where can I get more information?
American Radio Relay League (ARRL) and QST Magazine

CQ Magazine

The call for Bay Area Makers is open now. The deadline is Sunday Feb 15.

What’s a Maker? Take a look at what a lot of us are doing in The Maker Movement.

But if you think this idea is new, read this post about re-inventing the wheel. In this case, the wheel is the definition of “Maker.”

The Paella Feast at Maker Faire Bay Area 2014!   Leave a comment

Every year, the Maker Faire hosts a paella dinner for the Makers. This year, the event was sponsored by Liquid Wrench. Here are some images, and you can watch the Paella video on channel KH6WZ. . . 

Gerard’s Paella feeds 2,500 people very quickly!

Not Your Grandpa’s Ham Radio at the Bay Area Maker Faire 2014   Leave a comment

This is our third consecutive appearance at the Bay Area MF, and continues my theme of showing how some ham radio operators continue the tradition of “teaching, mentoring, making, modifying, repairing and improving” radio and radio-related technology. Read my post about ham radio and the Maker movement.

Today’s ham radio operators have an incredible amount of exotic surplus material that can be converted into everyday use on the ham radio bands. Grandpa certainly never heard of surface-mount technology, talking on homemade 47 GHz transmitter-receiver systems or pocket-sized, satellite navigation systems (GPS). But he sure did mentor, make, modify, repair and improve the equipment in his bedroom radio station…..
