“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”

― Sun Tzu, The Art of War

In what might appear to be a radical departure from past posts, stick with me! This one is more of an expose on the democratization of publishing books. This is because technology has made the business of word smithing to self-published pulp fiction a fully direct process without the limits of a professional experienced editorial team, agent, or sales force.

Back in the “good old days” before the likes of Amazon KDP (Kindle Direct Publishing) if you wanted to publish a book, you basically could go two routes – shop your manuscript or book concept around to publishing houses and see if anyone would take it for their catalog. As an unknown, the hope of a nice “advance” or publishing contract was your reward. If not, there was always the manual self-publish approach. This required finding an affordable production shop that could work with you. The main barrier here was money. If your book was text only then that placed your work at a much less expensive price per copy than any color process. And if your book was filled with color illustrations and photographs like a travel guide, then the cost of production (and often the minimum order!) would rise. You would need to do whatever minimum run the print shop required because the presses and binding machines needed enough copies to make it profitable for the printing company.

And this required usually a not too small sum for those first run copies! Wow, you’re now a “published” author. But being independent, it was up to you for placement and sales. You would not have the marketing resources nor automatic placements in major bookstores, nor the inside experience of people whose livelihood was built on the success of authors and book sales.

In other words, it was a brutally challenging system unless your market was already in place. Like the college professor who writes the book for their class, updates it and makes sure next year’s edition requires the purchase of new copies to match! But fast forward to today. What has changed?

A huge change has come in printing press technology. This blog has covered a lot of things that have been (and continue to be) disruptive forces on manufacturing – specifically additive manufacturing. The technological advances of “3D printing” have enabled even a 6 year old to produce plastic parts on demand from an inexpensive spool of filament. Did a similar approach to technology change the printing press? Unknown to most folks, indeed it has.

High speed digital book presses are how things are done these days. Print on demand used to be the domain of copy shops, but now complete books (especially paperbacks) can be made on demand for mass production and at rather amazing prices. The overhead of earlier printing technology has been reduced to the point that the equipment is more like a copier than a printing press. Dry inks, much the same as in a laser printer, speed the process. But on top of the ability to print books directly, a digital press has something else important to offer.

Digital presses are essentially huge production machines capable of churning out massive volumes of prints with impressive quality. Unlike their non-digital counterparts, what truly sets digital presses apart is their speed. The lack of set-up time means that you can do multiple print jobs back-to-back faster than you could on an offset or analog press. Plus, most digital presses use dry ink or toner, both of which require a lot less drying time than regular ink.” (https://www.stptexas.com/blog/what-are-digital-presses)

Example: I recently published a 100 page 8.5 x 6″ full color book at the highest quality possible from Amazon KDP. A single copy at the first tier quantity price is $8.65. Made on demand in one copy or a thousand – no minimum order. Maybe it is hard for you to appreciate that, but considering my order quantity was a dozen books, that is astounding compared to the times of the offset press. The delivery time? Two weeks! Yes offset presses are still being used (especially for higher quantities like a magazine) but I could never justify an offset production of my book in such limited quantities.

Now one side effect of this is the field of potential published authors has expanded exponentially. Anyone with a word processor can write and publish a book. No experience or up-front capital needed and no real writing talent required, although I would agree that quality still sells and is important for a book to succeed. But self-publishing no longer has the time and expense barriers that existed in pre-digital press days.

So hold that thought for a moment. Lets consider a pyramidal economic model. This is not a fancy end of life thing for an ageing pharaoh… (forgive the pun) but rather an economic system in the shape of a pyramid. Perhaps the phrase “pyramid scheme” comes to mind? That can be something illegal but there are plenty of legal pyramid schemes both obvious and more hidden.

Many years ago I was invited to lunch by a new college colleague. The invitation was urgent – “I really need to talk to you about something that could change your life!” Was this a religious message from a devoted Christian who was not certain of my salvation? But a free lunch (at the college cafeteria at faculty discount rates) was not something to dismiss. We set up a time to get lunch and on the appointed day we met at the central cafeteria. Finally sitting down at the table, I almost expected him to open the time with a prayer, but no – he went right to the “pitch.”

And what was this life changing message? I could break out of the low wages of a college professor by becoming one of his Amway sales consultants! Sure, sell Amway and your life will never be the same! Cases of motor oil, laundry detergent, etc. – the things everybody wants (yet not at Amway prices of course – the local grocery and auto stores were cheaper!). You see I already heard the “pitch” from my wife’s oldest sister – who sold Amway – and we already knew the outcome was poor. Amazon Prime I believe was part of its decline, not to mention numerous lawsuits and criminal business investigations.

Why was Amway a “pyramidal economic scheme?” Another name for this system (likely to avoid any connection to the former name) is Multi Level Marketing.

These systems generally work like this. You start out at the lowest level. You build your sales and sales force to increase your flow of goods and returns. By adding to your “network” eventually your income is a take from what would be their profits, and so forth, until the lion’s share was made at the corporate level. Thus like a pyramid, there are many at the “bottom” supporting the levels above (with likely the least return on a sale and who also have the most direct support to the customers). The higher you go, those who earn the most are the levels fed from the ones below. Who at some point may not even be selling anything! Often working with the cultural idea of the American dream, the promise of independent wealth lies ahead!

Many people who join MLM companies are not able to make a profit, and the vast majority of people who join these companies will not earn enough money to make it worth their time and effort. In fact, The Federal Trade Commission (FTC) reported 99% of people who participate in MLM lose money. In a legitimate direct sales or network marketing company, the focus is on selling a product or service to customers. However, in an MLM company, the focus is often on recruiting new members, who then recruit more members, rather than on selling a product or service. MLM companies often require their members to buy and stock products, which can be expensive and can lead to members losing money if they can’t sell the products. Some MLM companies require members to invest in the company, which can be risky and lead to financial losses if the company doesn’t perform well. MLM companies often make unrealistic income claims that can be misleading and can lead people to believe they can make a lot of money quickly, which is not the case.

OK, so by now you’re probably wondering why pyramid schemes and MLM’s factor into book publishing. Fair question. But first one more analogy.

High school is a wonderful time before going for independence. Many great opportunities exist and most high schools offer some range of sports. And what is the top of the heap? (again, pun pardon please) The most popular is football. Every athlete dreams of an eventual NFL contract and a seven figure pro ball career. In 2023-24 1,031,508 high school boys participated in football. (https://highschoolfootballamerica.com/high-school-football-participation-grows-for-2nd-straight-year/) How many NFL players are there? About 1500 on an active roster each season. (https://www.profootballnetwork.com/how-many-players-are-on-an-nfl-roster/) A simple calculation provides the chance any one player in high school will see themselves on an NFL roster:

0.14 percent. Or put another way, 99.86 percent of the players on all of the high school teams in the US will not be on an NFL roster. To be fair, the football participation is for all high school varsity teams playing 11 participants. About 7% will play in college making 81,000 players. So using that college figure gets us closer to reality: 1.85% of those players will likely make up the 1500 in NFL, but that assumes a fresh roster each year – which is definitely not the case. Thus it should be clear that dreams of a lucrative NFL career are very low.

Now that doesn’t mean that playing football in high school or college is valueless – there are many good things – building character, teamwork, friendships, etc. that come from organized sports. Not to mention the changing rules about “amateur” athletes and their ability to earn on their standing. But as is said, “don’t quit your day job,” professional football is the rare exception.

Do you see the parallels to multi-level marketing and pyramid economics? Many players at the “bottom” and only a few richly rewarded ones at the top. This is of course only about the money and not the incidental benefits mentioned previously.

MLM “models” then can be both obvious or hidden — or at least unintentionally out of sight.

Which takes me to publishing books! [and you thought I’d never get there] Lets take one genre for which I have some meaningful estimates of publishing rates – young adult fantasy. While there are a number of subtypes, I’m lumping anything tagged Young Adult Fantasy together.

“The “Big Five” traditional publishers (Penguin Random House, HarperCollins, Simon & Schuster, Hachette, and Macmillan), along with mid-size independent presses, account for a highly curated portion of the market. Traditional publishers release approximately 300,000 to 400,000 new titles across all genres annually in the United States. Of this traditional pie, fiction makes up roughly 20% to 25%.

Within the traditional fiction sector, science fiction and fantasy generally account for 10% to 15% of titles. Therefore, it is estimated that traditional publishers release between 8,000 and 12,000 traditional fantasy books each year. These titles benefit from large marketing budgets, professional editorial teams, and widespread physical bookstore distribution.” (https://www.thelegacyghostwriters.com/blog/how-many-fantasy-books-are-published-each-year/) That is quite a lot!

And for independent authors? “The vast majority of the answer to how many fantasy books are published each year lies in the independent publishing sector. Platforms like Amazon Kindle Direct Publishing (KDP), IngramSpark, Draft2Digital, and Smashwords have democratized the publishing process. Fantasy, alongside romance and science fiction, is one of the most dominant genres in the self-publishing world. Indie authors frequently employ a “rapid release” strategy, publishing multiple books a year to satisfy voracious reader demand and manipulate retail algorithms. Because of this, the volume of indie fantasy books dwarfs traditional publishing. It is estimated that 50,000 to 80,000 self-published fantasy books are released annually. This includes full-length novels, novellas, and serialized fiction collections.” (ibid.)

Do I sense a pyramid economic system here? Self-published fantasy authors in the U.S. sold an average of 1,200 copies per title in 2022, with the top 10% selling over 10,000 copies. (https://worldmetrics.org/fantasy-publishing-industry-statistics/) However, 41% of independent authors sold no more than a handful of books.

What is the message here? The sheer numbers of YA fantasy books being put out both in traditional and independent sales channels is staggering and speaks to a market that is saturated with publications. For an indie author to break out of the 41% class requires a high degree of careful placement, writing content, and quality that attracts long-term readers. Serialized novels with a rapid release approach help to build retail algorithms that steer readers to those works. If you only put out say 3 novels in 9 years the chances of being in that average of 1200 sales numbers is rather scant. The sales algorithms tend to steer consumers to products that are selling. For an “average” independent author, 1200 sales converted to direct royalties [assuming some price and costs] is about $6-7000 gross a year ($500-600 a month!) – hardly more than a good side gig or hobby sales.

The digital printing press has brought the business of making books to the masses, and like the high school football player or the bottom tier Amway salesperson, dreams of hitting the “big time” are nice but unrealistic. I don’t mean to discourage anyone from pursuing their publishing dreams, but they should not be surprised that best efforts are not rewarded. A good high school football player does not forecast an NFL top earner – even though they play well and try hard.

Know your enemy. Know yourself. And if neither, then the outcome will likely be failure or at least not the outcome you were desiring. 🙂

A story of “shock induced” instant repair

Instant Elevator Repair

I’ve waited to post this story for several reasons but it is still a good example of how repair of commercial items like elevators can be a problem for older equipment.

Consider a three-level church building where a stair lift / wheelchair lift is installed on the railing of the stairwell. This system while in good mechanical shape (less than 50 hours total use since new) stopped working one day. It has three stop positions – bottom floor, midway and top for the sanctuary level. Each can call the lift.

So the church called in an elevator company to repair it. They told them it would cost $1000 for the visit. And then another $1000 to diagnose it (no guarantee of repair). That is a pretty hefty fee for what turned out to be no work at all. The diagnosis? “We can’t fix it only replace it for $50,000.” They probably were not there more than 30 minutes. And like a lot of small churches, they didn’t have a spare $50,000 for a replacement.

A friend of this church asked me if I’d be willing to evaluate it to provide a second opinion. Sure – why not? I couldn’t do any worse than the elevator company, and it came with a free breakfast at a nearby local restaurant!

After breakfast, my friend and I went to the church and were introduced to the broken lift system. It had some life in that a few control indicators were lit, but it didn’t respond to any commands. Like a lot of these systems, most of the control is in a “wand” that is mounted on the moving lift cage. Working my way through the three platform levels, I finally came to the top.

At the top of the system was a large brown metal box. While not labeled as such, it was the main control panel and the motor that drove the chair. Opening it required the removal of two screws and then the cover popped off easily.

What was rather evident to me from some of the trash inside the control box was that probably the elevator company didn’t even inspect this! You’d think for $2000 you’d get some value from them. Anyway, after a few minutes looking at LED indicators on the power supply it appeared that at least the power was present for it to work – no blown fuses or tripped circuit breakers. As it often is, there were no schematics, but I clearly recognized some PLC components from past experience. Also, this is where I found the hours of use meter – like an odometer on a car. Yes, just 50 hours, though a lot of years of service. What this meant to me was mechanically it should still be in good shape, barring any abuse.

After noting several plug-in boards and relay controls, I was inspired to try one old trick. I call it the “shock induced readjustment” method… which in this case meant kneeling down to apply a stiff slap on the control box. I guess you could call it “electronic chiropractics.” You see, over time plug-in component assemblies can suffer from contact oxidation – moisture and other airborne contaminants. Rather than taking the controls apart, often these sorts of issues can be “shaken out.”

Sometimes the results of this approach can be dramatic. I closed my eyes and gave the box a nice firm shock – enough to resonate through the upper floor but not enough to hurt my hands. And guess what? The entire system sprang back to life – and is working still to this day – much to the utter amazement of the pastor and my friend.

Thus one good slap on the system control box saved that church $50,000! A nice Christmas gift. There was much rejoicing. Only wish they didn’t have to spend that $2000 for nothing on the elevator repair company.

The Right to Repair depends on Parts and Information

A few weeks ago an eight year old 80″ Sharp Aquos TV set turned on then within seconds went dark. And it didn’t come back. In fact, the tiny LED lamp in the bottom center of the case was also dark. This could only mean that the power supply board was not working. A few days before a lightning strike made a very loud boom nearby. I’m guessing the failure was related to that event.

Modern flat screen TVs are quite modular. Generally there is one TV board that contains the tuner and inputs with processing, a backlight controller for the LED lamps, and another board that controls the LCD panel for the display. Working together, these 3 boards comprise 90% of the electronics (some TV’s have other smaller boards for special functions).

To keep a modern LCD TV working, the power supply board actually stays on all the time, providing a “keep alive” voltage – generally 5 volts – to the processor on the TV board. That way when you press the power button on the IR remote control, there is a subset of the electronics that responds to the command. This usually means a signal is sent to the power board to “light up” all of the rest of the voltages needed to run the set.

The power supply board from a Sharp Aquos 80″ LCD TV

Now it would be nice if sets had schematics and / or block diagrams inside the case. I remember the days of such documentation included in the back of major appliances. But no more. And with the modularity of TV electronics, replacing boards is about all a current TV dealer can do, often resorting to third-party sources, like eBay to obtain them. This appeared to be my fate in repairing this 80″ Sharp, but alas, no power supply board was to be found on eBay or other parts sites that dealt in these units. And of course, the manufacturer, Sharp in this case, will not even sell you the parts or any diagnostic diagrams. That is for an authorized dealer. But what if the authorized dealer can’t order parts either? Well, they are no more able than someone searching on the sites I did.

Realize the original price for this 80″ set was over $2000. Consigning it to a landfill seemed to be a huge waste. It was working well before the failure. What to do??

Almost every power supply in use today is a switched-mode design. The input line voltage is rectified, then fed to a high-frequency oscillator and using ferrite transformers. This AC output is then rectified, cleaned up and regulated to the DC voltages needed. This design removes the need for heavy iron transformers with higher losses to do the same AC to DC conversion but at 60Hz line frequency.

The primary side was working – the high voltage DC was there. But in the secondary side a key component, a 100V 5A diode, was shorted out. This diode is the one that creates the 5V keep alive DC voltage, and twenty cents later and a bit of soldering, the entire power supply was working. The diode? A BR5100 Schottky high-speed power diode, widely available.

So 10 hours later of diagnostic time (I’m ashamed I didn’t find it faster) all back to normal. And a spot in a landfill saved at least for the present!

Finally, here is that 20 cent device! Can you spot it in the upper right section of the power supply???

And don’t forget the tiny picosatellites!

With all of the fuss about the tiny high altitude hobby balloons, you might not know there are also a few low-earth orbit small satellites up there! Yes, these tiny 125 cubic centimeter packages are circling the globe and sending data to ground stations around the world. The map above is a snapshot showing the location of some of these orbiters (blue satellites) and the location of active ground stations (green antennas) that receive them. Each ground station uploads data through the internet to a central site which collects the reports and shows them on the map.

There are a lot of useful scientific experiments although the original intent was to create a “poor man’s SpaceX internet.” This hasn’t happened yet, but this has not been around all that long for a complete system to take shape.

These devices use low power spread spectrum, or LoRa communication modes to achieve downlinks that work well with small inexpensive ground stations. Indeed, a complete ground station costs under $40 if you have to start from nothing. Which is rather amazing given what you’d have needed just a decade ago.

Constructing and getting a picosatellite into orbit is a bit more expensive compared to the cost of launching a high-altitude balloon of the sort ham radio operators do. Thus these are frequently the domain of college/university groups and other space research outfits. The first one launched using this model was in 2021. This was FossaSat-1- the next advancement in picosatellite technology, sized at only 5x5x5cm and weighing only 250g. It is inactive as of March 2023.

Don’t burst my balloon!

Don’t Shoot!

The recent news of 3 more balloons shot down by US fighter jets has many folks worried about everything from other spying activities to alien invasion.  However, given what I know from the media (which can be unreliable, nevertheless) I have a strong theory about what those 3 balloons most likely were.  And if so, the truth should help you calm down about these incidents, if in fact you were a bit worked up with them.

All 3 balloons fell into a general description that I know as a “radiosonde.”  For many, many years and even now, satellite-based data gathering operations for weather prediction just don’t get the kinds of data you can get from a radiosonde.  In fact, as a youngster in the 60’s,  I often dreamed of one landing near me to recover for “reverse engineering.”  Instead, I bought some off of surplus markets to learn their inner workings!

So what is a radiosonde?  It is a small electronics package designed to receive GPS location information and at the same time measure temperature, barometric pressure and humidity (in the most common scenario). In turn, it relays that information to ground stations via a small transmitter.  Battery operated, they have a finite lifetime in use of a few hours. There are no cameras or video downlinks – just the data mentioned above. Wind speeds are reflected in positional changes. These are launched with balloons filled with helium such that they reach a maximum altitude and burst, leaving the small electronics package to plummet back to earth.

And who exactly sends these out?  There is really quite a mix of folks who do.  And as long as they are following established FAA rules, there is no need involve things such as permits or licenses.  These are typically less than 4 pounds, often much less.  The National Weather Service sends these up every day from different locations around the US.  Universities do, private research firms do and so do Amateur Radio enthusiasts around the world.  Some years ago at the college where I taught the Plastics Department crafted the high altitude balloon and the Electronics Department made a suitable tracking payload.  At least 2 were recovered – one in northern New Jersey.  Most of the others flew out to the Atlantic and were lost in the “soup.”  Every day, dozens of these are released all over the world.

If you don’t conclude from this description that these devices are harmless “robots” directed by the upper atmosphere winds, then I haven’t done my job well enough. I’d encourage you to do some net searches and see what is out there on the radiosonde topic!

Can you see what is up there in real time?  Indeed you can!  I took a snapshot of a reporting page from sondehub.org as I was writing this blog entry on a Sunday afternoon.  Here is what I found:

There is a lot of detail on the map, and I encourage you to go to sondehub.org and get a map of your current area.  The map is interactive, and the legends are well-explained.  So long as the radiosonde is programmed to send its information on certain common reporting frequencies, ground stations (often radio amateurs!) report those received via internet to sondehub.org, and they in turn create a realtime map with location data and other information about the devices aloft.  There is also a special version of the site that only reports amateur radio balloon beacons, https://amateur.sondehub.org

I’d be remiss if I didn’t add some additional detail about those sent up by the Amateur Radio folks (and also, other technology-based clubs out there, more on that later).  Nothing says you can’t have a solar cell array to power your device.  The main limitation is weight (4 pounds), so radiosondes sent in this small category are not going to be physically huge or pose a threat to the ground.  The pico-balloons of radio amateurs are barely over a few ounces. Yet these humble payloads can traverse the entire globe so long as they remain intact.  These might have been the types that China claimed flew over them!  Once released, these small devices are entirely at the whim of the winds. Indeed, after being blown up by an AIM-9X missile, there was nothing to recover!

Launching high-altitude, circumnavigational pico balloons has emerged only within the past decade. They are designed to be neutrally buoyant at around 43,000 feet. An 11-gram tracker on a tether, along with HF and VHF/UHF antennas to update their positions to ham radio receivers around the world. At any given moment, several dozen such balloons are aloft, with some circling the globe several times before they malfunction or fail for other reasons. The launch teams seldom recover their balloons.

Recently NPR published an article on the Alaska balloon, and you can read it here: https://www.npr.org/2023/02/18/1158048921/pico-balloon-k9yo  This was a balloon created by amateur radio hobbyists for their own learning and research purposes, and was launched under clear FAA rules for such projects.  If you really want to get into the “nuts and bolts” this site has kits ready to go for enthusiasts to purchase!   https://www.picoballoons.net/

Other balloons are sent aloft to test spacecraft components and physics experiments: https://www.npr.org/2023/02/21/1158303780/when-research-balloons-shot-down-scientists-worry

Yes, a payload that fails or doesn’t report through the standard means could pose some risk.  But if NORAD simply got a spare computer to put sondehub.org up for monitoring, we might save some stress on aircraft and early warning systems.

Methinks a half-million dollar missile to down a $100 harmless balloon seems like an overreaction, if not a waste!

A brief diversion into an amateur radio mode

As I mention in my “About Me” page I’m a long-time amateur radio operator. Ham radio for many might be thought of as an anachronism in the times of cell phones and internet. If you picture modern ham radio as just two operators “ragchewing” on a weird sounding single sideband transmission, you have hardly scratched the surface.

For plenty of reasons, I have largely worked on digital modes and what is known as QRP. Which in layman’s terms means low transmitting power (and to some extent inexpensive) equipment. While around as an operating option since about 2009, Weak Signal Propagation Reporting (WSPR) finally made it into the news last year in a big way, and it is one of the digital ham modes I operate. I’ll explain why in a bit.

What is WSPR? It is a narrow band, slow speed digital mode that is a transmission consisting of a call sign of the sender, the station’s Maidenhead grid location on earth and the transmitter power. This is a beacon sent out only to see where it might be received – there is no “2-way” communication but for the aggregated reception reports created by receiving stations published on the web.

WSPR was produced by Joe Taylor, a ham operator (K1JT) and Nobel Physics prize winner. In the past, he’s developed other transmission and reception methods to help with moonbounce and meteor scatter radio work.

My beacon transmits sporadically day and night using 200 milliwatts – on 40, 30 and 20 meters (essentially a spot on the 7MHz, 10MHz and 14 MHz ham bands). Your typical Class 2 bluetooth devices use 2.5 milliwatts of transmitter power, going at best 30′. But my 40 meter WSPR transmission can make it across the Atlantic depending on conditions! Here is a map of my 40m beacon one recent evening.

40 meter beacon January 8, 2022.

A you can see, my signal was heard to the mid-west and all the way to Europe! As I’m sending several different amateur radio band beacons here is what my map looked like on Friday evening, January 14:

One-hour reception map, 6:00pm January 14.

So what purpose does this serve besides some bragging rights for operating a QRP digital mode? For one thing, this mode provides valuable radio wave propagation testing on a real time basis on shortwave bands. But another use is what made the headlines: predicting where a lost airliner might be found!

Think of each brief beacon “hop” as a digital tripwire. If something passed through its path the propagation would be “disturbed.” This disturbance along with some others in the same general region could be used to track locations of the object that made the changes in signal. All of the beacons are stored in a database, so a researcher can go back and recreate conditions that existed in the region at the time of interest. And an aerospace engineer in Germany did just that for the missing Indonesian MH340 plane: https://hackaday.com/2021/04/24/wspr-may-hold-the-key-to-mh370-final-position/

Will it be where he predicted? Stay tuned (sorry about the pun) – perhaps we will find out in 2022!

What is ahead for 2022?

Now that is a loaded question! The end of the COVID thing? Self-driving cars that actually work? A $20,000 electric vehicle with 450 mile range? [I’d go for a Mr. Fusion like Doc in Back to the Future]

Mr. Fusion? Compact Fusion Reactor Will be Available in 5 ...

No doubt 2022 will continue to bring some new innovations to meet the challenges of these days. How about the focus of much of this blog: Additive Manufacturing?

I suspect that 2022 will be more incremental improvements, especially in novel materials. I don’t expect a $500 3D metal printer for home use, but I do expect that prices of 3D metal printing will continue to become more affordable from vendors such as Shapeways and Xometry. New novel polymeric materials could also be an important aspect of even home-based equipment.

Anyway, I’d suggest looking past the news of pandemic problems to stories of problems solved in 2022!

A bit of topical diversion and a surprise delivery

So this is not additive manufacturing per se, although it was used to prototype the device early on by the developers.

In 2018 I backed a project on Kickstarter for a metal detector that showed a lot of promise – Air Metal Detector – which used a smartphone app to run the system through a Bluetooth connection. The basic idea was to reduce the cost to just the active components in the coil and support structure while providing the option for more sophistication with the application. OTA updates of application and embedded coil software would permit fixes and improvements. Along with this was the potential to reduce weight but the final weight of course depends on the choice of phone. Promised delivery was for November 2019.

Air Metal Detector (from Kickstarter page: https://www.kickstarter.com/projects/airmetaldetectors/air-metal-detector-the-smart-bluetooth-metal-detec/description)
Air MD application as shown on Kickstarter project page

Fast forward to June 2021 – just as I was going on our first out-of-town vacation to a New Jersey beach resort, I got an email from FedEx stating that a package was being delivered the following day that required a direct signature. Thankfully FedEx now has package hold options at DollarGeneral stores, so I picked the one that was going to be on my return trip path home! But the sender listed made no sense to me and I had no direct notice that this was going to be the long awaited Air MD unit, though some weeks earlier I got a request to confirm my shipping address from the project.

In going back to the Kickstarter project page I soon realized I was in a very unique position at least for now – apparently I’m one of 3 or 4 to receive this out of 299 or so folks who pledged for it. Thus this hasty post (with more details to come) to prove I’m not making this up!

As received package.
The detector with phone mount installed and fully collapsed shafts.
OLED screen after power up and charging port.

It did connect to the app on my iPhone and a quick test with a 25c piece worked as expected, but this is just a quick “all systems go” outcome. I’ll be working on more extensive tests and collecting some user experiences to share in the next day or so. If you have questions you’d like answered in all that, leave it in the comments. Two quick things from me already – the charging port is magnetic like Apple products and is unprotected from the elements. And there is no changing out an eventually defective battery – the head is sealed to IP65 standards they say, and I see no way to service anything inside.

Stay tuned for updates! I plan on comparing this to a Nokta Makro Simplex, which is my current favorite detector.

A bit of an update – I was waiting for the Android app to become available as it was not on the Play store or downloadable through their web site. But I continued to check. It did get out recently. I had some connectivity problems with Bluetooth – it would try to connect then shortly lose the connection with a cryptic error message. This did not happen on my iOS device – an iPhone 5. I am inclined to use the Android option because of a much bigger screen. My first test was on an LG G3 Stylus. However, after trying it on another Android phone I got the same response. The app installed on both Android platforms without any error or warning messages.

Weather here in the last 2 weeks has been lousy and wet, and whenever I’ve had an opening for a test I’ve been discouraged by all that. But I’ve turned on comments for this post, so please suggest things for me to try. I was out to a very rural wooded site using the Nokta Simplex to find old iron pins for a property survey – not exactly treasure hunting, but still valuable to the owner. I found all of them in quick succession, except for one that by rough measurement was under a large snowplow blade! Too much iron for sure.

And one more impression – I had occasion to try some comparisons with my Nokta unit at the end of the summer, in between rain and other chores needed when it wasn’t! If I had to choose one or the other I’d pick the Nokta. Both were pretty reliable in the simple stuff like coins thrown into my yard tests but I found the Air MD unit a bit “fussier.” While I want to do some “calibrated” tests at depth, time for that has eluded me so far. I have not found any of the major commercial vendors of metal detectors selling or reviewing it as of November 2021, but I’ll add any I find here. Plus, sooner or later I’ll probably find a more specific use for testing – or if you are reading this, please suggest one!
