Crosstown Traffic: EEVBLOG Anatomy of an eBay Scam

Leave a comment

Dave Jones risks his identity to educate all of us on the anatomy of an eBay scam.  Actually he was never in any serious danger as he recognized the signs all along.  But an interesting story nonetheless about how a scammer can take you to a place where they end up sending you a manual invoice (not connected to the auction itself) so that eBay buyer protection will no longer apply to you.

So by now it’s clear how this scam works:

  • They set up new ebay and payapal accounts
  • A really good scammer would hack an existing ebay account, or increase the feedback by buying a ton of 99 cent items from other fake accounts of theirs etc, but this one was content with zero feedback.
  • List something exotic but one that would have high demand, and do a really good job with the listing making out they are the owner who needs to sell it because it’s not needed any more.
  • Deliberately set up the PayPal account in foreign currency so the (almost certainly US or other major country like Australia) buyers PayPal checkout will fail.
  • Make it out they have no idea what’s wrong and that they are sending an invoice manually, and try to convince you that ebay ok’d this.
  • Sucker pays the money and they vanish with it. Maybe they might complete the scam by sending you an empty box with tracking number, but they have their money, so they probably won’t bother.

Thanks Dave!

Ham Radio on TV: ARRL reports that NBC to launch new TV series based on the 2000 movie “Frequency”

Leave a comment

The ARRL reports that NBC is going to launch a new television series based on the 2000 movie “Frequency”:

Mike Baxter, KA0XTT — Tim Allen’s character in the “Last Man Standing” TV show on ABC — may be getting some competition on the ham bands, as NBC appears poised to launch a television series based on the 2000 movie Frequency, in which ham radio — aided by some spectacular solar phenomena — plays a central role in the sci-fi thriller.

According to a November 13 article in The Hollywood Reporter, NBC has already committed to the series. Jeremy Carver is writing the script for Warner Brothers Television and will be the series’ executive producer. Toby Emmerich, who wrote the movie, will be a co-producer.

While Amateur Radio has made only fleeting appearances in “Last Man Standing,” it is an essential plot device in Frequency. In the movie, a New York City fireman, Frank Sullivan, played by Dennis Quaid, re-connects via a bizarre ham radio link with his son, John, 30 years in the future. Jim Caviezel, now a star in the CBS drama, “Person of Interest,” portrayed John Sullivan, an NYPD detective. John Sullivan comes across his late father’s 1960’s-era Heathkit transceiver, through which — with the help of quirk of nature and some Hollywood magic — he is able to communicate with his father through time and space.

Once back in touch, father and son conspire in efforts to change the past while also untangling their complicated personal relationship. Both also attempt to prevent a murder.

The ham radio theme and the chance to see vintage ham gear and real, glowing vacuum tubes (Frank Sullivan’s old Heathkit has no cover) on the big screen were sufficient to generate considerable interest within the Boat Anchor community when the movie debuted. The ARRL worked with the film’s producers. Frequency remains widely available in DVD and through video services. — Thanks to John Bigley, N7UR, Nevada Amateur Radio Newswire

Crosstown Traffic: Hackaday reports that the Larson Scanner namesake Glen A. Larson has passed away

Leave a comment

Glen Larson will always be remembered for producing quality television shows such as Knight Rider, Battlestar Galactica, and Magnum, P.I.  But his association with a row of red lights that flashes in a back-and-forth pattern is legendary with those into building electronic circuits and programming microcontrollers.  After managing to make a microcontroller display “Hello World” on an LCD, or making an LED flash with a 555 timer, the next logical step was to emulate the “Cylon Eye” from Battlestar Galactica, or the eight-light scanner from the front of KITT using 7400-series TTL chips or an Arduino.  If you could make each individual segment ramp up or down with PWM instead of abruptly turning on or off, you were a genius!  Unfortunately, Hackaday reports via CNN that Glen Larson has passed away at the age of 77:

[Glen A. Larson] passed away on Friday at the age of 77. He may be most widely recognized for being a producer of the original Battlestar Galactica, Magnum, P.I. and Knight Rider television series’. But for us his association with a row of LEDs which illuminates in a back and forth pattern will always be his legacy.

When we heard about his passing we figured that we would hear about his invention of the Larson Scanner but that was not the case. A bit of research turned up a pretty interesting Wikipedia bio page. He has origins in a music group call The Four Preps and actually composed or collaborated on a number of television theme songs among other notable accomplishments. But nothing about electronics. Did this man of many hats actually invent the hardware for the Larson Scanner used as the Cylon Eye and on the front of K.I.T.T., or does it simply share his name?

Evil Mad Scientist Labs claims to have coined the term Larson Scanner. [Lenore Edman] confirmed to us that EMSL did indeed start the term which is used to name their electronics kit and directed us to [Andrew Probert] who lists effects for the TV series on his portfolio. We’ve reached out to him for more information but had not heard back at the time of publishing. We’ll update this post as details emerge. In the mean time, if you have any insight please leave it below including the source of the information.

If you are not aware, a Larson Scanner is so interesting because the pattern calls for a fading trail of LEDs. It is not simply a fully illuminated pixel moving back and forth but includes dimmed pixels after the brightest one has passed. This is an excellent programming challenge for those just getting into embedded development.

Rest in peace, Glen, and thanks for entertaining all of us in our youth.

In the News: Fort Wayne Hamfest article – This is why you issue detailed and well written press releases for amateur radio events

Leave a comment

So I caught this in on the WANE-TV website in Fort Wayne today about the Fort Wayne Hamfest that I attended this weekend.  This is why radio clubs need to draft detailed and well-worded press releases when you hold a public event.  Look below at the text of the article I copied in.  After each paragraph I break in to describe “interesting” text that can either be blamed on an incompetent reporter or an incompetent editor.

FORT WAYNE, Ind. (WANE) Amateur Radio, also known as Ham Radio, is a hobby that features licensed participants whom operate communication equipment. The Fort Wayne Hamfest & Computer Expo was November 15 and 16 at the Allen County War memorial Coliseum.

1) “whom operate?” I’m fairly sure this is an inappropriate use of “whom.”
2) “licensed participants” — this is iffy.  “Licensed radio operators” would have been a better phrase.
3) Missed the capital “M” in “memorial”

Crosstown traffic: Hackaday features my “FatFingerer” on their front page

Leave a comment

Whether this was the result of people actually liking my project or just some random randomizer picking featured projects, I saw this on the Hackaday front page this evening (and no, I wasn’t logged into my account on Hackaday, and yes, I checked this from multiple browsers to make sure this wasn’t a cookie thing…) :

I detailed my FatFingerer to my friends on Facebook a number of months ago, I do plan on adding a detailed writeup to my blog in the near future… I use the FatFingerer every day at work when using AutoCAD and PLC applications, the heart of it is an Arduino Leonardo programmed to emulate common keystrokes.  And yes, if you’re interested in more detail right now, here is my Hackaday.io project page for the FatFingerer.

Crosstown traffic: The most extreme PC board repair I’ve ever seen

Leave a comment

Extreme repair of PC board that was burned up after a capacitor failure. Hackaday photo.

Hackaday featured this guy’s extreme repair of his JBL subwoofer.  The power board had fried — it literally burned up in a catastrophic failure caused by leaking capacitors.  I looked at the details of his repair on his website and it was, quite frankly the most creative and professional repair I have ever seen.  Instead of buying a new board, or ditching the subwoofer and buying a new one, he actually cut out the damaged portion of the power supply board and used the amplifier service manual and Photoshop to create a new board to fit the hole.  His site is mostly pictures, the following quote is from the Hackaday article referencing his site:

[xsdb] had a real problem. His JBL L8400P 600 watt subwoofer went up in flames – literally. Four of the large capacitors on the board had bulged and leaked. The electrolyte then caused a short in the mains AC section of the board, resulting in a flare up. Thankfully the flames were contained to the amplifier board. [xsdb’s] house, possessions, and subwoofer enclosure were all safe. The amplifier board however, had seen better days. Most of us would have cut our losses and bought a new setup. Not [xsdb] he took on the most extreme PCB repair we’ve seen in a long time.

After removing the offending caps and a few other components, [xsdb] got a good look at the damage. the PCB was burned through. Charred PCB is conductive, so anything black had to be cut out. The result was a rather large hole in the middle of an otherwise serviceable board. [xsdb] had the service manual for the JBL sub. Amazingly, the manual included a board layout with traces. Some careful Photoshop work resulted in an image of the section of PCB to be repaired. [Xsdb] used this image to etch a small patch board.

The amplifier and patch were milled and sanded to match up nearly perfectly. Incredibly, all the traces aligned. [Xdsb] soldered the traces across the join with small sections of wire and solder wick. After soldering in some new high quality capacitors, the amplifier was back in action!

In the News: Washington Times-KC1ACF “has world at his fingertips”

Leave a comment

Another fantastic article featuring amateur radio in a positive light.  Yesterday the Washington Times featured Mark Vess KC1ACF:

While Vess has reached operators from exotic locations across the world, their conversations often revolve around everyday occurrences.

“In most cases, it’s your life that you share with other radio operators.

Vess said radio operators adhere to a set of unwritten rules that promote a cordial atmosphere over the air. Religion and politics are hardly ever discussed, and repeatedly trampling over other operators’ conversations will quickly earn you a reputation as a jerk.

Among the different countries Vess has reached by radio include Cuba, Italy, Spain and England. However, he said most of the conversation conducted voer the air is done in English.

“Amateur radio spans the world. It’s in every populated area and especially in unpopulated areas,” Vess said.

Friends of Mine: Jason KE4NYV turns a wooden pen on the lathe

Leave a comment

When my friend Jason Rausch KE4NYV isn’t building APRS trackers or watching rockets explode at NASA Wallops, (he was there that awful day two weeks ago), he hones his skills as an accomplished woodworker.  And even though I lack any woodworking skills because of my lack of fine motor control and coordination, I still find this kind of thing impressive–I used to love watching Norm Abram on PBS.  One of the things that Jason enjoys building are wooden pens.  Today he posted this instructional video on YouTube:

In the News: “Why is Ham Radio more popular than ever” from the Saugerties Times in Kingston, NY

Leave a comment

The Saugerties Times in Kingston, NY reports that ham radio is more popular than ever!  From the Times:

With a smartphone in every pocket, isn’t amateur radio a thing of the past?

The answer, as was clear at the Woodstock Rescue Squad Headquarters on a recent Saturday afternoon, is no, far from it.

“Year to year [the number of licenses issued is] increasing, which is not what most people would tend to expect,” said Keith Tilley, certified instructor with the American Radio Relay League.

The occasion was a two-day licensing class organized by the 55-member-strong Overlook Mountain Amateur Radio Club, which was founded in the 1960s. Participants learned the basics, took a test and received their call signs a few days later.

Over 725,000 Americans have ham radio licenses, up more than 60 percent since 1981, according to NPR. Perhaps part of the appeal is the charm of analog, which has made LPs the fastest growing music format in recent years not transmitted over a wire. Compared with the amount of incoming data on a web browser with several social networking and messaging apps running, ham radio is refreshingly focused. Another factor: preppers. Our increasing interconnectedness and diminished self-reliance have nurtured a certain strain of anxiety that can only be relieved by having all supplies on hand for a worst-case scenario— including communications.

Always good to see a complimentary piece in the news!

Famous Hams: New President and Vice President of Indonisia are both hams

Leave a comment

I missed this last month!  I caught it on last week’s Ham Nation during Don AE5DW’s Newsline report (at exactly 20:00 on the video).  The ARRL Reports:

Indonesia’s new national leaders are both Amateur Radio licensees.

President Joko “Jokowi” Widodo, YD2JKW, holds a General class license. Vice President Jusuf Kalla, YC8HYK, is an Advanced class licensee.

Elected in July, Jokowi, 53, a former furniture exporter, and Kalla, 72, were inaugurated on October 20 in Jakarta. Indonesia is the world’s third-largest democracy, with a population of approximately 250 million.

Secretary of State John Kerry represented the US at the inauguration and met with the new president afterward. Jokowi previously served as governor of Jakarta and as mayor of Surakarta.
