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.”

Christmas Boat Update: D25 Wins Another First Place Award   Leave a comment

All that hard work paid off. D25, Peter Barbour’s entry in the Newport Beach Christmas Boat Parade earned First Place, Best Animation/Special Effects. This is the 11th time D25 has won an award in the parade.

The theme for 2014 was “Something’s Cooking in the Kitchen” and included a boiling tea kettle on a stove with smoke (steam) effects. All of the items on the sail area are animated and are controlled by a total of four computers.

If you look closely, a Christmas “Easter Egg” is planted on the stove. Do you see it? Maybe this photo, taken when the decorations were still under construction will help.

An argument about a detail on D25 for 2014

Still don’t see it? When Steve was painting the final touches on the stove, a heated discussion took place. Should the clock on the stove be analog or digital? What time should it show? Our thinking process went from “I doesn’t matter” to “Midnight. Doesn’t everyone wait until midnight to open all the gifts?” to “Wait. Christmas. December 25. Boat is named D25. 12:25!”

Here are some more images of D25 under construction . . .

 

Other 2014 Newport Beach Christmas Boat Parade Winners are posted on the official Newport Beach Christmas Boat Parade website.

Peter is N6RAS. D25 includes Amateur Radio equipment as well as a GPS and APRS locator/tracking system on board.

What’s in store for Christmas 2015? Only Peter knows – but we can all look forward to something amazing!

Parts Among Potato Salad – The SBMS Summer BBQ at W6DQ   Leave a comment

 

Immediately after the San Bernardino Microwave Society (SBMS) Tune-Up Party at the Fairview Park in Costa Mesa, the annual summer BBQ was held at the QTH of Dennis, W6DQ.

As usual, the food was great, and Dennis did a great job at the BBQ. It is nice to be a guest at a BBQ every now and then….

Probably the best thing I enjoy at these events is catching up with the club members and see what projects they are working on.

 

The Original Makers   Leave a comment

Anyone interested in young people education has probably heard of the Maker movement and the Maker Faire. Or, at least, they may have seen a copy of Make: magazine on the newsstands. Many educators understand the connection between science and technology education and how this Maker movement can be used to make learning fun.

Well, I have to say this is a lot of successful marketing hype – since so many people worldwide think this is a new and wonderful phenomenon. Here’s some news for everyone: This is not a new idea. Amateur radio operators (“hams”) have been among the original Makers since the early 20th century.

In case you have not heard about Makers, here is a brief description: The Maker movement is about making something rather than buying something, fixing it rather than throwing it away, pre-cycling or recycling instead of throwing it away and modifying something to make it work better or different.

This “making” refers to anything you can think of, from clothing and costumes and computers to bicycles and cars and aircraft. And for ham radio operators – it’s making or modifying radio communications equipment.

A Personal Passion and Mission
Since ham radio has been and continues to be one of my passions, I want to make sure people understand that today’s ham radio is not an outdated, dying hobby that no one uses any more. It is not necessarily a hobby for old retired engineers talking to strangers from their basements and closets. The Amateur Radio Service is much more chic and many of us are using today’s technology and applying it to ham radio activities. And as a science and an educational tool, ham radio has a lot to offer.

A Timely Showcase
The Bay Area Maker Faire is at the end of May each year. Sponsored by Make magazine, the Maker Faire website describes this event as, “A two-day, family-friendly festival of invention, creativity and resourcefulness and a celebration of the Maker movement.”

When you actually get there, you may describe it as a giant playground for everyone where science, art, food, clothing, bicycles, fire, machines, lasers, steam, electricity and music all crunch together into one giant gathering. And I can insert ham radio into this cornucopia of educational fun.

In 2012, my ham radio friend Dennis Kidder had some free passes to the Bay Area Maker Faire. Since the tickets were a great bargain, we had to make the all-day drive to the Silicon Valley to see this thing. We had such a great experience that year we decided to create our own display to show off our ham radio projects. Besides, we got to meet Grant Imahara from the Discovery Channel show “Myth Busters,” and a famous female hacker named Jeri Ellsworth. Adam Savage, also from the Myth Busters show, is the Maker Faire emcee.

Amazingly, Maker booths are free. Considering how much commercial exhibitors pay for booth space, electricity, water, compressed air and cleaning for tradeshow booths, this is an incredible deal.

For 2014, my Maker Faire theme, “Not Your Grandpa’s Ham Radio!” continues for the third consecutive year. Our displays include a wide range of experiments, demonstrations and practical wireless communications equipment using a mixture of traditional and the most modern techniques. Here are some examples of our projects from previous Maker Faire events…

Arduino Radar Shield at Maker Faire Bay Area 2014   Leave a comment

University of California, Davis Engineering Project at Maker Faire Bay Area 2014

IMG_0090 kh6wz radar experiment UCDavis

This radar system operates at 2GHz (S-band). The Arduino stack consists of a radio front end, controlled by an Ardunio Uno and signal processing is performed using an Arduino Due. A Bluetooth link moves the data from the radar system to the notebook computer, where the radar information can be seen using a “waterfall” visual display.

The Software Defined Radio (SDR) at Maker Faire Bay Area 2014   Leave a comment

Not Your Grandpa’s Ham Radio

Dennis W6DQ displayed his Flex 1500 software defined radio with 10 GHz and 24 GHz transverters. There were many questions about SDRs and many visitors were surprised to learn ham radio operators have this technology. But this is another example of what radio hams are using these days. The system Dennis showed is actually three systems in one: The SDR, which is being used as the “intermediate system,” and transverters (transmitter-receiver-converters) for 10 GHz and 24 GHz microwave ham radio. The posters briefly explain the transverter system:

APRS: Automatic Packet Reporting System – and High Altitude Ballooning

Someone asked if it would be possible to track a high altitude balloon using ham radio. It is possible to track a vehicle, aircraft or person using the amateur radio application called APRS, the automatic packet reporting system. Basically, the system consists of a two-way radio (usually for the 2m ham band), a GPS receiver, a modem to interface/control the data to and from the GPS, and an antenna for the radio and the GPS.

By coincidence, I am collecting parts for such a system, see the photo above. The radio antenna is on the left –  it is a piano wire dipole for the 2 meter ham band. On the upper right is a Byonics Tiny Trak SMT – the interface between the two-way radio and the GPS. Inside the orange plastic box is an old 2m handie-talkie, with its cabinet parts and battery pack removed. Not shown in the picture are the other ingredients, which include a tiny GPS module and the video cameras for Amateur Television (ATV).
