Review: Arduino Workshop by John Boxall
The folks at No Starch Press kindly sent me a copy of John Boxall’s Arduino Workshop. I opened the box with a little reluctance as it was roughly the fifth book on Arduino I’d read and none of them were very useful. I’m not an electrical engineer or computer programmer by trade (and I’m often jealous of the many hams who are who can throw together amazing things off the top of their head).
I’m happy to report that Arduino Workshop was the first book I’ve read that helped me really make sense of the practical applications the Arduino is capable of. I spent last night really thinking about what the difference is between those books, and this one. I came up with the answer. This book is the first one which provides real-life projects that seem to make sense in a broader context. Specifically, using the Arduino to solve a real problem or add depth to more mundane projects.
OK, it’s not the first book I’ve read on the Arduino that uses project examples. The difference is, this is the first book where the examples are something more intriguing than 1) build a LED that blinks, 2) watch it blink a lot, #) Yay, you’re done! If I can’t see applicability, my mind tunes out quickly. It’s OK to build a simple flashing LED as you’re beginning to learn, but it’s certainly not the nadir of all projects.
OK, take a look at the projects in this book. They’re just fun sounding!
- Creating a Blinking LED Wave
- Controlling Traffic (building a working traffic signal — one of my favorite projects!)
- Creating a Single-Cell Battery Tester
- Creating a Quick-Read Thermometer That Blinks the Temperature
- Creating a Temperature History Monitor
- Creating a Temperature Logging Device
- Creating a Keypad-Controlled Lock
- Building and Controlling a Tank Robot
- Creating an Accurate GPS-based Clock
- Building a Remote Control Thermometer
- Creating an Arduino Tweeter
- Building an Arduino Texter
These are only just a few of the projects. The cool part is it really gives you a foundation to build, say, an Arduino project that Tweets the temperature from a remote sensor. You can see how the jump to Amateur Radio-related applications is not far at all.
Anyway, check out the book if you — like me — have been wanting to explore the Arduino but didn’t know where to start. This book gives you everything you need to go from zero to some pretty amazing projects!
If you’re looking to get started without buying the book, the author has a nice Arduino tutorial section on his website. Also, the publisher provides a sample chapter to see if the book might be for you. The book is available in both a print edition ($29.95) and ebook ($23.95). If you purchase the print edition on their website, you also get the ebook edition at no extra charge. If you haven’t had a chance, check out the official Arduino website. Another good resource is a Yahoo! group called HEAP (Hams Exploring Arduino Programming).

Prayers for Boston
As of now, news agencies are reporting two people killed and dozens injured at the Boston Marathon after two large explosions. Please say a prayer for those affected by this and for the first responders working so hard.
Getting started with PSK
A reader from North Carolina, USA, wrote to me and asked the following:
A question: I am a just a general class ham. I would like to know exactly what it takes to operate on PSK. I have a TS140s, a key and a dipole at 50′. I also have a Compaq laptop computer with a sound card. Can someone tell me what I need to buy — not just in generalities — to help me get up and running with this mode?
Would those of us with some experience with PSK (definitely not me!) take a shot at answering him? If so, please reply in comments. Thanks in advance!
Learning How To Solder
My son is beginning to take a real interest in electronic circuits. As a ham, I should feel uniquely qualified to show him the world of radio and electronics.
But I never really learned how to solder. Not well, at least. Sure, I can solder a PL259 onto the end of some coax and it works OK, but the connector usually hides the sloppiness of my handiwork. Don’t get me wrong, I’m not scared of a soldering iron — I just am not as practiced with it as some of the QRP kit builders that frequent this blog.
I searched online for an interesting kit to build and stumbled upon Elenco’s AmeriKit AK-100 Learn to Solder Kit (about $15). What better opportunity to teach myself teach my son how to solder!
The kit includes a 25-watt soldering iron (Elenco SR-1N), a pair of diagonal cutters (Elenco ST-1), a spool of lead-free solder, and a solder practice kit containing a printed circuit board and various components. Also included is a nice 15-page guide to soldering and very detailed instructions about how to assemble the practice project. (I’ve yet to be disappointed in anything from Elenco. If you have kids or grandkids and they don’t have Elenco’s Snap Circuits Jr. Kit, it’s the best $20 gift you can buy them!)
This kit was a huge hit with my son. He had a great time placing each component in its clearly labeled place. After doing a few of the practice exercises, I was amazed at how proficient he became! I learned so many tips from the instruction manual about how to create good solder joints and electrical connections. The manual itself is well worth the price — the soldering iron and practice kit are a great bonus!
The included soldering instruction booklet covers general electronics basics like determining resistor and capacitor values, paying attention to polarity, and safety precautions. It also covers specific soldering (and desoldering) techniques for different types of work. There is an in-depth look at the different types of solder (when you would or wouldn’t use them) and many tips and tricks to making your job look more professional. You’ll have to excuse our solder joints in the pictures, however — there was a lot of learning and practicing going on! 🙂
After about an hour and a half, the project was done! We had a working siren with flashing red LEDs. My son couldn’t have been more proud of his work! Although we have done quite a few “tech” projects together, this was the first time we’d really gotten into circuit fabrication. It was time very well spent and I’m very excited to be creating a solid foundation of good habits. It’s always better to learn the right way instead of trying to erase bad habits later!
If you have a son or daughter (or grandchild!) interested in electronics, don’t hesitate to check out Elenco’s Learn To Solder Kit. Like Elenco’s other educational kits, it was well worth its modest price.
Who was Irving Vermilya?
Randy Dorman, KB3IFH (of KB3IFH QSL Cards) sent me an e-mail last night about a QSL card that he found listed for sale on eBay:
Randy contacted the current owner of the call, Bruce Randall, W1ZE, who shared an amazing bio of the original owner written by Donna Halper, Ph.D. I contacted Dr. Halper and asked if she’d allow me to share it. She replied that it needed some updating, but very graciously allowed me to reprint the original version from 1996 below. I’m sure you will enjoy it… and if you get a chance, check out her book, Boston Radio: 1920-2010, available on Amazon!
Irving Vermilya—America’s #1 Amateur
by Donna Halper, PhD
If you were alive during the formative years of amateur radio, you knew Irving Vermilya. From the time he was 12 and he traveled with his dad and his family’s minister to Canada to hear Marconi speak, amateur radio was his first love, and he was a life-long ambassador for it. (The story goes that after the talk, which was mainly attended by adults, Marconi came over to the young lad and encouraged him in his interest in wireless. He even gave young Irving a piece of equipment, which became Irv’s first receiving set.)
Born in June of 1890, Vermilya grew up in Mt. Vernon, New York, where he built that first rather primitive set in December of 1901, after returning from his trip to see Marconi (as he later recalled, it looked strange, but it worked). Other more advanced (and more professional-looking) sets followed, and his dedication to wireless increased. His spark transmissions were so frequently heard that he was offered jobs on ships that needed a wireless operator. He became a member of the newly formed Radio Club of America in 1911, using the calls VN. (Later, he would use 1HAA, but he was best known as W1-ZE). In late 1912, the government began to require that all wireless operators be licensed. Irv hurried to the Brooklyn Navy Yard to take the test, and was given Certificate of Skill #1. For the rest of his life, he would be known as America’s Number 1 Amateur—which he truly was.
Irv Vermilya’s involvement with radio continued; at the age of 16, he did in fact go to sea as a wireless operator; a few years later, he was given the important job of running the Marconi Wireless Station, WCC, on Cape Cod. During World War I, he served in the Navy, and then returned to Massachusetts to run the RCA wireless station at Marion. His engineering and wireless skills brought him into contact with such legendary figures as David Sarnoff, Lee DeForest, and Edwin Howard Armstrong.
By 1921, professional radio stations were springing up, and Irv was interested in this new technology too. Using his newly acquired license for a land station, 1ZE, he began doing radio broadcasts in late April (according to the Boston Traveller‘s ham radio column, he got special permission to be on even before he received the official license in May); his plan for 1ZE was to both promote amateur radio and to entertain his neighbours in and around New Bedford and upper Cape Cod with concerts and local information. His work came to the immediate attention of the Slocum and Kilburn Company, which was planning to open a station at their mill (the mill was similar to what we would call a “general store”, since it also sold electrical equipment, tools, and building supplies; the station would be located in the radio department). They hired Irv to build it and run it, and the station went on the air officially the last week of May 1922 as WDAU. (A “cousin” of WDAU still exists, although today, it is known as WNBH; these initials stand for New Bedford Hotel, where its studios once were located. Interestingly, thanks to the consistent link of Irving Vermilya as owner or engineer, WNBH claims to be the 11th station in the US, tracing itself back to 1ZE in mid 1921 and then to WDAU. However, the evidence seems to suggest that while Irv worked at 1ZE, WDAU, amd WBBG, the first two never directly evolved into WNBH. 1ZE remained on the air, in fact, long after he was hired to build WDAU. 1ZE was renamed by the government as W1-ZE, but Irv still owned and operated this well-respected ham station for over 40 years. Slocum & Kilburn kept WDAU on the air briefly even after Irv left to put WBBG on. It was WBBG that really evolved into WNBH; the station first began to broadcast under those calls in early November of 1925. But being the 11th station in the US makes a great story, and it has been repeatedly stated as a fact both by WNBH and by the New Bedford media. Given Irving Vermilya’s many achievements, it doesn’t surprise me that he receives credit for one that may not totally be accurate.)
When financial problems beset Slocum and Kilburn in late 1923, Irving acquired the station’s equipment and moved it to his house (imagine his wife’s surprise) in January of 1924. He began to operate it under the call letters WBBG until mid-1925. (His was one of many small stations that suffered when ASCAP required all stations, no matter what their size, to pay large fees to play ASCAP music; such fees almost drove Irv’s little station off the air, but it made him even more determined to find some financial backers so that he could keep the station operating.) He was finally able, with business partner and fellow ham radio operator, Armand J. Lopez, to move his radio station back to New Bedford in November of 1925, requesting the aforementioned WNBH call letters. It was common in radio’s early days for stations to have studios at hotels, since this provided a studio audience as well as a house dance band, and it certainly gave WNBH a good community image to have the hotel as its location. Irv continued to play a major role in WNBH’s operation, serving as its General Manager, as well as helping to hire the talent and getting the station publicity. His ability as an engineer was well-known, and he frequently kept the station up and running during winter storms or other weather-related problems. In May of 1934, he sold WNBH to the owners of the New Bedford Standard-Times newspaper, but he continued to work there, first as station manager and later as the chief engineer until he retired in 1955.
While Irv Vermilya’s career in professional radio earned him considerable praise, he never stopped being involved with ham radio. In 1921, he was named the New England Manager of the ARRL. He was the mentor to Eunice Randall, the district’s first woman amateur, and at a time when women were not expected to know anything about radio, Irv was totally supportive of Eunice and encouraged other men to give her a chance—Irv and Eunice were friends for many years, participating in various conventions together, and of course, keeping in touch via their ham sets. Irv wrote columns on ham radio for QST and for various newspapers, and won virtually every award a ham could win—it was impossible to read any magazine about ham radio without seeing another country or continent that W1-ZE had received or been received by. (In the early 1920s, amateur ‘tests’ were often held to see how far a transmission could go, and Irv was one of the few whose messages were received as far away as Europe.) And as you might expect, he also put a mobile transmitter in his car, and in the early 1930s, he set up the first police radio station for the New Bedford Police department (WPFN). In fact, whenever he could put his radio skills to a positive use, Irv was right there to volunteer, whether it was relaying messages during a hurricane or attracting some publicity for ham radio by engaging in a “foot-sending” contest with Eunice Randall (Eunice usually won). Years later, he was one of the founding members of the Old Old Timers Club, and served on its board. He was also the first American citizen ever given a permit to operate his mobile station in Canada.
I would like to tell you that such a distinguished career and such a highly respected man lived to a ripe old age, but not every story has a Hollywood ending. Depressed by the death of his wife, in failing health, and perhaps feeling the radio industry no longer had a place for him, in late January 1964, Irv Vermilya committed suicide. His death came as a shock to the many people who had admired him; even the Standard-Times editorialized about what a fine human being he was, and how much he had contributed to broadcasting.
Irving Vermilya elevated the status of ham radio, and was an able spokesperson and emissary, whose outgoing personality made friends wherever he went. If it were not for him, New Bedford and large parts of Cape Cod would not have had a professional radio station until the 1930s, and thousands of people who met him via ham radio would not have known what fun this hobby could be. He was a strong believer in community involvement, and whatever station he ran, be it amateur or profession, it would always do its part to help the community. Perhaps he never invented something major the way Marconi did, perhaps his name is not as famous as Sarnoff’s, but it is radio’s early pioneers who paved the way for the fledgeling industry to grow and succeed. Irving Vermilya devoted his life to radio, and he deserves our thanks for that dedication and his many years of service to the industry he loved so much.
