He passed in 2018 - one of the best of the best.  His collection is up for sale this October 27th at Sotheby's:

The Ricky Jay Collection
Magician, actor, scholar, author: the range of Ricky Jay’s accomplishments were as varied as are the formats and subjects of the material in his celebrated Collection: books, pamphlets, posters, handbills, broadsides, prints, ephemera, objects, and apparatus documenting the histories of magic, circuses, jugglers and acrobats, automatons, remarkable characters, learned animals, limb-deficient artists, con men, and scores of other related, if arcane, topics. Featuring characters of the greatest celebrity to the utmost obscurity, The Ricky Jay Collection will offer an astonishing variety of material in a sale that is truly without precedent.

Ricky Jay is one of the very select company of persons who assembled a collection of the very first rank in a field in which he was not only a world-renowned practitioner, but also a scholar of considerable note. Jay documented his collection in a series of books that both highly entertaining and thoroughly erudite, including Learned Pigs & Fireproof Women, Jay’s Journal of Anomalies, Extraordinary Exhibitions, and Matthias Buchinger: “The Greatest German Living.” Jay’s source material for these and other publications will now be available for the elucidation and entertainment of other collectors—as well as the legions of Ricky’s admirers—at Sotheby’s auction of The Ricky Jay Collection, October 27 and 28, 2021. We invite you check this page often for updates.

I would want to go there just to watch people. Here is just one small taste of Ricky's work - more can be found on YouTube

Well crap - RIP Sir Clive Sinclair

| No Comments

The guy who invented one of the more popular small computers.  I still have mine:

20210417-treasures02.jpg

From The Guardian:

Home computing pioneer Sir Clive Sinclair dies aged 81
Sir Clive Sinclair, the inventor and entrepreneur who was instrumental in bringing home computers to the masses, has died at the age of 81.

His daughter, Belinda, said he died at home in London on Thursday morning after a long illness. Sinclair invented the pocket calculator but was best known for popularising the home computer, bringing it to British high-street stores at relatively affordable prices.

Many modern-day titans of the games industry got their start on one of his ZX models. For a certain generation of gamer, the computer of choice was either the ZX Spectrum 48K or its rival, the Commodore 64.

Belinda Sinclair, 57, told the Guardian: “He was a rather amazing person. Of course, he was so clever and he was always interested in everything. My daughter and her husband are engineers so he’d be chatting engineering with them.”

He left school at 17 and worked for four years as a technical journalist to raise funds to found Sinclair Radionics.

Genius - also invented a very quirky and fun electric vehicle and a lot of other things.

So true - add Marconi to this as well

| No Comments

Tesla is one of my heroes.  The guy invented a lot of things that we take for granted - the AC single and polyphase motor, the system of power generation, transmission and distribution that the world uses today, fluorescent light, radio (demonstrated a much more complex version several years before Marconi's three dots). He played around with and took X-Ray images before Roentgen's paper (complained about the radiation burns too).  The number of products this guy invented that we still use today boggles the mind.

This cartoon only begins to sum it up:

Clever hack - welding

| No Comments

The primary concern is blocking ultra-violet light from the welding arc.  Just as it gives your skin sunburn, it can do a number on the cornea of your eye.  Glass does an excellent job of blocking UV light.

20210911-welding.jpg

About 20 years ago, a friend of mine and I went in on a decent small wire welder setup.  The first time I worked with it, I did not have a fire-proof work surface so I used the garage floor. Squatted down and welded away for the better part of the afternoon.  Wore long-sleeve sweatshirts, jeans, gloves, helmet, etc...  I forgot my feet.  I wore sandals and socks and woke up the next morning with very sunburned feet.  Hurt to walk for a few days - the skin blistered.

Of course - the Air Force

| No Comments

Looks like they are a well-run organization.  Or maybe not. From Task & Purpose:

Air Force software is so bad the guy in charge of it all is about to quit
If you’ve ever struggled with a government computer still running on Windows 2000, know that you’re not alone. In fact, the military’s cybersecurity infrastructure and software development enterprise is in such a bad state that the Air Force’s first-ever Chief Software Officer will soon resign because it isn’t worth fighting the entire bureaucracy of the Department of Defense just to get some basic information technology issues fixed.

“We are running in circles trying to fix transport/connectivity, cloud, endpoints, and various basic IT capabilities that are seen as trivial for any organization outside of the U.S. Government,” wrote Nicolas Chaillan in a LinkedIn post announcing his resignation on Thursday. “At this point, I am just tired of continuously chasing support and money to do my job. My office still has no billet and no funding, this year and the next.”

Ho. Li. Crap. I would think that software would be a primary consideration.  So many systems to coordinate. Here is another viewpoint:

“Success in tomorrow’s conflicts will largely depend on how warfighters are able to harness and adapt everything from mission systems on aircraft to sensor packages, networks, and decision aides,” retired Air Force Lt. Gen. David Deptula and Heather Penney who are respectively the dean and senior resident fellow for The Mitchell Institute for Aerospace Studies, in a July policy paper on network and software development.

“To prevail in a dynamic and contested battlespace, warfighters must be able to reprogram and reconfigure their weapon systems, sensors and networks,” they wrote. “Yet the Air Force continues to develop, update, and manage software and architectures in a highly centralized and stove-piped fashion.”

Like duuuuuhhhhhhh... One example:

Although the F-22 and F-35 are the only two 5th generation fighters in the Air Force inventory, they cannot share information with each other machine-to-machine,” because they use incompatible datalinks that were developed 10 years apart, they wrote. “Today, the F-22 and F-35 fleet still cannot exchange information without the aid of an externally hosted gateway, one which is still in the experimentation and demonstration phase.

Our tax dollars at work. We need to clear out the bureaucracy and start over.  The people who have spent the last 30 years there are in no position to lead let alone tread water. They are doing our Nation a disservice by staying. I was expecting it to be bad.  I was not expecting it to be THAT BAD.

Happy 200th Birthday - Electric Motor

| No Comments

Changed civilization. From IEEE Spectrum:

200 Years Ago, Faraday Invented the Electric Motor
In 1820, the Danish physicist Hans Christian Ørsted threw electromagnetic theory into a state of confusion. Natural philosophers of the day believed that electricity and magnetism were two distinct phenomena, but Ørsted suggested that the flow of electricity through a wire created a magnetic field around it. The French physicist André-Marie Ampère saw a demonstration of Ørsted's experiment in which an electric current deflected a magnetic needle, and he then developed a mathematical theory to explain the relationship.

English scientist Michael Faraday soon entered the fray, when Richard Phillips, editor of the Annals of Philosophy, asked him to write a historical account of electromagnetism, a field that was only about two years old and clearly in a state of flux.

A bit more backstory and then this:

On 3 September 1821, Faraday observed the circular rotation of a wire as it was attracted and repelled by magnetic poles. He sketched in his notebook a clockwise rotation around the south pole of the magnet, and the reverse around the north pole. "Very satisfactory," he wrote in his entry on the day's experiment, "but make more sensible apparatus."

The next day, he got it right. He took a deep glass vessel, secured a magnet upright in it with some wax, and then filled the vessel with mercury until the magnetic pole was just above the surface. He floated a stiff wire in the mercury and connected the apparatus to a battery. When a current ran through the circuit, it generated a circular magnetic field around the wire. As the current in the wire interacted with the permanent magnet fixed to the bottom of the dish, the wire rotated clockwise. On the other side of the apparatus, the wire was fixed and the magnet was allowed to move freely, which it did in a circle around the wire.

Of course, I am a big Nikola Tesla fan and we must not overlook his patents from 1988 for the first Practical electric motor. Some primitive direct current motors were built in the 1830's but Tesla was the first person to develop alternating current (single and polyphase current) motors.  These are the first practical substitute for steam.  The foundation of the Industrial Revolution.

Oh Joy - my latest hobby

| No Comments

Been watching the local airplanes via their ADS-B flight transponders. Did a $20 receiver, a home-made antenna (designs available all over the place) and a spare RaspberryPi computer and that was it.  Loaded the software from FlightAware and joined their network. I also joined ADSBExchange as FlightAware filters out all non-civilian or non-commercial flight information and I have a Naval Air Base just across the bay.  C'mon man...

Anyway, got this in my inbox:

We would like to be the first to tell you about a recent event – Collins Aerospace has announced its intent to acquire FlightAware.

Let’s talk about what that means for FlightAware's ADS-B network.

Most importantly, Collins recognizes the importance of the ADS-B ground station network and is committed to maintaining and expanding it. This acquisition opens up resources to deliver new hardware innovations, better open-source software solutions, and a variety of web and mobile improvements to benefit the flight tracking community.

Well crap.  They could be Geek Gods and just leave FlightAware alone.  They might even fund it some more and improve it. Unfortunately, what happens all too often is that this will be "played with", it will never really fit into the Corporate Culture and in 2-3 years, it will become abandonware. Cue up a generation or two of new operating systems (Windows 11 for example) and the software will no longer run. Grrrrr...

But then again, I am still really pissed off at how EMagic's SoundDiver was handled.  It was available for Windows and MAC and then in 2002, Apple bought them out. Dropped support for the Windows version, fiddled with it for a year or two and then abandoned it. It was a library program for musical instruments that had amazing support for a huge range of synthesizers and effects processors.  It would allow you to manage audio samples, MIDI sequences, MIDI configurations, basically control your whole setup from one very nicely laid out window. Double Grrrrr....
Corporate idiots - buy the stuff but they do not use it so they do not know what they have.

Hertz so good - New Orleans

| No Comments

The mention of 25Hz pumps in the last post caught my eye.  The national grid runs on 60Hz (60 Cycles per Second).  25 Hertz (abbrv. Hz) (named after Physicist Heinrich Rudolf Hertz) was pioneered in some of the first commercial power generation operations starting with Nikola Tesla and George Westinghouse's Niagara Falls station in 1895. This lower frequency is better for torque but much less efficient for transformers.  They require larger cores and are more expensive to make.  25Hz is not good for lighting either as it will cause flicker.

Several frequencies were tried and the overall compromise was made for 60Hz and also for 50Hz for those people wanting to avoid paying the Tesla/Westinghouse patent royalties (Europe and Japan chiefly).
A good history here: History Of Power Frequency

25Hz is still used on some railroads on the East Coast: Amtrak's 25 Hz traction power system and more here: NHRHTA New Haven RR Forum but these applications are for ancient and legacy equipment.

I am wondering just how old the pumps in New Orleans are...  On one hand, if it ain't broke and things were definitely built to a higher standard back then.  On the other hand, what is the up-time?  The reliability? Can these pumps handle overloads?  How well do they integrate into the present monitoring and control system for the City?

Strange story at DIY Photography:

UNIVERSAL’S REACH EXTENDS BEYOND EARTH – CLAIMS COPYRIGHT OWNERSHIP OF THE MOON
If you share a video on social media and it contains someone else’s copyrighted work, you’re bound to get a claim from the content owner. But what happens when you get it for your own work? This weird thing happened to filmmaker Philip Bloom when he shared his video of the full moon. It got removed because, apparently, videos of the moon were copyrighted to Universal Music Group. Wait, what?

Philip shot truly gorgeous footage of the sunset moon in Skiathos, Greece on 22 August. He used a Sony Alpha 1 with a Sony 100-400mm GM and a 2x teleconverter. He was excited to share it with his friends and followers, so he posted it on Facebook. However, he got this notice: “Your video is blocked and can’t be viewed in 249 locations.” the reason for this was that the video “matches 30 seconds of video owned by UMG.” So instead of deserved positive feedback, Philip was slammed with a copyright infringement from UMG.

Much more at the link.  Universal Music Group was using AI to scan new submissions to YouTube and their algorithm flagged Mr. Bloom's image. AI has its uses but is it really ready for primetime yet?

So true - programming

When I do it, I call it Bugging.  I am writing bugs and the occasional line of clean code sneaks in:

From Wired:

The FTC Votes Unanimously to Enforce Right to Repair
During an open commission meeting Wednesday, the Federal Trade Commission voted unanimously to enforce laws around the Right to Repair, thereby ensuring that US consumers will be able to repair their own electronic and automotive devices.

The FTC’s endorsement of the rules is not a surprise outcome; the issue of Right to Repair has been a remarkably bipartisan one, and the FTC itself issued a lengthy report in May that blasted manufacturers for restricting repairs. But the 5 to 0 vote signals the commission’s commitment to enforce both federal antitrust laws and a key law around consumer warranties—the Magnuson Moss Warranty Act — when it comes to personal device repairs.

Big fan of this - you pay money for it.  You own it.  You have the right to modify or repair it.

As for the Magnuson Moss Warranty Act?

The FTC is also encouraging the public to report warranty abuse—as defined by the Magnuson Moss Warranty Act of 1975, which prohibits manufacturers from telling consumers that a warranty is voided if the product has been altered or tampered with by someone other than the original manufacturer.

You read that correctly. Those "Warranty void if tampered with" stickers on a product are illegal in the USA and has been for 45+ years. Manufacturers rely on people not knowing this.  I did not know about this until now.

Now if we can just find out who is running the current-day Phoebus cartel for home appliences, things will be a lot better. Phoebus cartel?

The Phoebus cartel was a cartel of, among others, Osram, Philips, and General Electric from December 23, 1924 until 1939 that existed to control the manufacture and sale of light bulbs.

The cartel is an important step in the history of the global economy because it engaged in large-scale planned obsolescence. It reduced competition in the light bulb industry for almost twenty years, and has been accused of preventing technological advances that would have produced longer-lasting light bulbs. Phoebus was a Swiss corporation named "Phoebus S.A. Compagnie Industrielle pour le Développement de l'Éclairage".

In other words, light bulbs "should" last about 2,000 hours.  No less and certainly no more. Cuts down on sales 'ya know...

Modern appliances are expected to last about ten years. No less and certainly no more.  Ask to have one repaired (I did recently) and receive a sales pitch that there are other elements that will fail and best to just replace the whole thing for only $8,000.  This for a heat pump that was only eight years old.  That unit replaced a heat pump that was over 30 years old. Go figure.

Riiiigggghhhht... A construction project gone awry - San Francisco's Millennium Tower

From the S.F. NBC affiliate:

HobbyKing sells radio controlled model aircraft, drones, cars, etc... They screwed up, they were warned, they ignored the warnings and are now paying a price. From the Amateur Radio Relay League:

FCC Fines HobbyKing Nearly $3 Million for Marketing Unauthorized Drone Transmitters
The FCC has issued a Forfeiture Order (FO) calling for HobbyKing to pay a fine of $2,861,128 for marketing drone transmitters that do not comply with FCC rules. An FCC Enforcement Bureau investigation stemmed in part from a 2017 ARRL complaint that HobbyKing was selling drone transmitters that operated on amateur and non-amateur frequencies, in some instances marketing them as amateur radio equipment. The fine affirms the monetary penalty sought in a June 2018 FCC Notice of Apparent Liability (NAL). The FCC said its investigation found that dozens of devices marketed by the company transmitted in unauthorized radio frequency bands and, in some cases, operated at excessive power levels. “Such unlawful transmissions could interfere with key government and public safety services, like aviation systems,” the FCC said. “We have fully considered HobbyKing’s response to the NAL, which does not contest any facts and includes only a variety of legal arguments, none of which we find persuasive,” the FCC said in the FO. “We therefore adopt the $2,861,128 forfeiture penalty proposed in the NAL.”

A matter of radio interference.
The HobbyKing transmitters were operating on frequencies used by other services.
What other services you might ask?

Aeronautical Navigation, GPS satellites, GLONASS navigation satellites, ATC-S navigation transmitters and Air Traffic Control.

I do not think that you would want to interfere with these services.  The idea that someone would design, build and market a device (actually, over 70 different devices) that would interfere with these services is unreal.  Downright stupid. They were notified of this.  They stonewalled.  They kept selling devices (and bringing new models to market) that interfered with these services. Transmitting with higher power than allowed is icing on the cake.  A "hobby" device like this is allowed one watt.  They were using up to three watts.

This is a Hong Kong company - wonder if the jamming (and excessive power) is intentional.  Something built in that can be turned on remotely. China is not our friend.

The full FCC Ruling is here: FORFEITURE ORDER

They make plug-in adapters for many popular battery tool batteries.  Use your rechargeable tool batteries to power other things. I could really see adding some of these to my ham radio Go-Kit.

They do not seem to carry any of the Harbor Freight batteries which is a shame as these are relatively cheap and decently made.  I have Makita tools and they only carry adapters for the 12-volt series, not the more modern 18-volt.

You will probably need to change the voltage to fit your needs but boost or buck converters are cheap and fairly reliable.

From the History Channel:

Nautilus submarine travels under North Pole
On August 3, 1958, the U.S. nuclear submarine Nautilus accomplishes the first undersea voyage to the geographic North Pole. The world’s first nuclear submarine, the Nautilus dived at Point Barrow, Alaska, and traveled nearly 1,000 miles under the Arctic ice cap to reach the top of the world. It then steamed on to Iceland, pioneering a new and shorter route from the Pacific to the Atlantic and Europe.

The USS Nautilus was constructed under the direction of U.S. Navy Captain Hyman G. Rickover, a brilliant Russian-born engineer who joined the U.S. atomic program in 1946. In 1947, he was put in charge of the navy’s nuclear-propulsion program and began work on an atomic submarine. Regarded as a fanatic by his detractors, Rickover succeeded in developing and delivering the world’s first nuclear submarine years ahead of schedule. In 1952, the Nautilus’ keel was laid by President Harry S. Truman, and on January 21, 1954, first lady Mamie Eisenhower broke a bottle of champagne across its bow as it was launched into the Thames River at Groton, Connecticut. Commissioned on September 30, 1954, it first ran under nuclear power on the morning of January 17, 1955.

Rickover was one of those people who show up every so often to show the rest of us how it is really done.
Absolute genius - in the same league as Tesla, Feynman, Einstein, DaVinci, Newton, Bach...

Of course not - COVID

| No Comments

From the MIT Technology Review:

Hundreds of AI tools have been built to catch covid. None of them helped.
When covid-19 struck Europe in March 2020, hospitals were plunged into a health crisis that was still badly understood. “Doctors really didn’t have a clue how to manage these patients,” says Laure Wynants, an epidemiologist at Maastricht University in the Netherlands, who studies predictive tools.

But there was data coming out of China, which had a four-month head start in the race to beat the pandemic. If machine-learning algorithms could be trained on that data to help doctors understand what they were seeing and make decisions, it just might save lives. “I thought, ‘If there’s any time that AI could prove its usefulness, it’s now,’” says Wynants. “I had my hopes up.”

It never happened—but not for lack of effort. Research teams around the world stepped up to help. The AI community, in particular, rushed to develop software that many believed would allow hospitals to diagnose or triage patients faster, bringing much-needed support to the front lines—in theory.

In the end, many hundreds of predictive tools were developed. None of them made a real difference, and some were potentially harmful.

More at the site.  The article does not mention this but I am betting two things:

#1) - the failure was much worse than they are letting on and
#2) - the reason was GIGO - they were not getting honest input data

The "science" floating around was and still is corrupted by the political narrative. There are no clear numbers to be found without a lot of digging and reading between the lines.

Wound up doing some more wiring in the garage.  A little too hot for yard work in the sun.

The current-carrying ability of a conductor is known as its Ampacity. Here is an excellent table to determine what wire size to use for what size of breaker and what expected load.  They also have a Raceway Fill calculator that allows you to see how many conductors of any given size should be placed in any kind of raceway (including flex and conduit (EMT)).

You are welcome 😁   CerroWire Tables and Calculators

CerroWire also makes a really good product - prefer them over other brands as the insulation is of high quality - consistent. Makes for fun shopping as CerroWire is carried by Home Depot which is my general go-to box store. Unfortunately, my favorite receptacles are made by Eaton/Arrow Hart which are only carried by Lowes. Eaton has better build quality than Leviton which is at H.D.

And of course, panels? Schnieder/Square D  Don't even bother asking for anything else.

Gotta admit that this is true...

Good - it will be expensive but they should have maintained their infrastructure.
From Los Angeles station KTLA:

Miami-Dade courthouse closes due to safety concerns after condo collapse
The Miami-Dade County Courthouse will begin undergoing repairs immediately because of safety concerns found during a review prompted by the deadly collapse of a nearby condominium building, officials said.

An engineering firm that examined the 28-story courthouse recommended that it undergo immediate structural repairs and that floors 16 and above be closed. All courthouse employees, including those who work on lower floors, will return to working from home, Miami-Dade Mayor Daniella Levine Cava and other leaders said in a joint statement late Friday.

In its report, engineering firm U.S. Structures Inc. said that during its June 30 inspection, it found structural distress in various structural members such as support beams and joists, including steel columns that are in “poor condition” and concrete columns that have numerous cracks.

All you Drama Student graduates working as a barista?  Should have hit the math books a little harder and become a structural engineer.  Be rolling in the money now.

Now all I need is to integrate the Vessel Tracking network and I'll be all set:

20210710-ship.jpg

The radio service is called AIS (Automatic Identification System) and there are some receivers out there but they are for commercial maratime and yacht use and priced accordingly. My ADS-B receiver was under $30 with sales tax and shipping included.  Looking around to see if there are any SDR/Raspberry Pi scripts - I have a couple extra Pi's (older versions) and two or three SDRs I have been using for Ham Radio services.

Found this one - I'll keep looking though - it just receives the signal and outputs an NMEA code string.  Looking for something that can integrate with a chart.

What can I say - I want it all. Now 💩

It fits over Google Maps - quite clever:  mapcoordinates.net

I am subscribed to a forum on the topic.

Someone was breathless - they posted that they saw a whole bunch of the Navy Lockheed P-3 Orion and the Boeing P-8 Poseidon aircraft flying into Florida.  Was this anything to do with the assasination in Haiti?  Was there something brewing?  Is the deep state planning a coup?

Another member of the list posted back that no, you dumbass, the airplanes are based in Florida.  They had flown away to escape potential damage from Hurricane Elsa. They were returning home.

ADS-B receiver - antenna

| No Comments

Getting some good data from my really crappy antenna.  Three days of operation and I have 62 contacts from more than 250 miles away and 863 from 200-250 miles.  Pales in comparison to the 57,755 contacts from overhead to 50 miles but still, it's working.

20210627-ADSB-contacts.jpg

First up will be to get the other script running and then build a better antenna and mount it on the roof.  The receiver is very small and talks to the computer through a USB cable.  Going to try an active cable to see if I can mount the receiver directly connected to the antenna in a weatherproof box.  Cut down on signal loss.
Always stuff to experiment with.
