Um…did you have a mini stroke, your first sentence is gibberish, not unusual from you but concerning.

The same bachelors degree can be gotten from Phoenix University online, so maybe it wasn’t easy for you, but it’s not an advanced or difficult BS degree to earn.
It’s not even circuitry design, just basic repair and manufacture skills. You don’t really need to know how circuits work, only how to diagnose and replace them when they fail. Essentially how to read a multi meter, manual, and how to solder. You’re a service tech, my brother had more advanced electronic skills when he was 12 and rebuilt/upgraded his apple 2 computer at home. Don’t pretend you have some advanced electronics degree, you have the bare minimum degree to be a professional service tech. 🤦‍♂️

Jethro wouldn’t have taken as electives, much less aced advanced molecular biology, or advanced placement B/C calculus and statistics. Jethro couldn’t tell the difference between your, you’re, and yore, or there, their, and they’re…that’s definitely more your level and speed friendo. 😂

It is a cool device, but you'd think he'd read through the entire tiny little instruction sheet before starting to film this vintage/hard-to-find/expensive solder joint in action...

OK, hold the fucking phone here. This video is just a disaster. It is flippant and glossing over the facts of what actually happened. This story is a favorite of mine, so I have done a lot a reading on it.

This happened in 1983 (36 years ago).

>> Do planes seriously not have a fuel gauge?

There is specifically a digital fuel gauge processor on that plane, and it was malfunctioning. There was an inductor coil that wasn't properly soldered onto the circuit board. At that time, planes were allowed to fly without a functioning digital fuel gauge as long as there was a manual check of the fuel in tanks and the computer was told the starting fuel.

The problem is that fuel trucks pump by volume and planes measure fuel by weight. The fueling truck converted the volume to kilograms and then converted to pounds. He should not have used both. In 1983 ground crews were used to converting volume to pounds. The 767 was the first plane in Air Canada's fleet to have metric fuel gauges.

The line in the video "the flight crew approved of the fuel without noticing the error" glosses over how it is actually done. The pilot was passed a form that contained the numbers and calculations from the ground crew that stated that 22,300 kg of fuel was loaded on the plane. The math was wrong, but unless the pilots re-did the numbers by hand, there wouldn't be anything to jump out at them. He accepted the form and punched those numbers in to the computer.

The 767 was one of the first planes to eliminate the Flight Engineer position and replace it with a computer. There was no clear owner as to who does the fuel calc in this situation. In this case, it fell to the ground crew.

>> I would hope there is a nit more of a warning system than the engines shutting off.

If there was a functional digital fuel gauge, it would have showed them missing half their fuel from the start, and the error would have been caught. Because there wasn't, the computer was calculating and displaying the amount of fuel based on an incorrect start value.

That is another problem with this video. It states that "they didn't even think about it until ... and an alarm went off signalling that their left engine had quit working."

Fuck you, narrator asshole.

In this case, low fuel pump pressure warnings were firing off before the engines shut down. They were investigating why they would be getting these low pressure warnings when their calculated fuel values (based on the original error) showed that they had enough fuel.

>> I can't believe the pilot's were given an award for causing an avoidable accident.

The pilots did not cause it. They followed all the proper procedures applicable at that time, 1983. It was only due to their skill and quick thinking that the pilots landed the plane without any serious injuries to passengers.

They ran simulations in Vancouver of this exact fuel and flight situation and all the crews that ran this simulation crashed their planes.

"Bad math can kill you." Flippant, correct, but still not quite applicable to this situation. Air Canada did not provide any conversion training for dealing with kilograms and the 767. Not the ground crew, nor the pilots, were trained how to handle it. They were expected to "figure it out". That, and the elimination of the Flight Engineer position, set these situations up for disaster.

Why? I'm asking as someone that has never soldered before.

How can he not know how to solder correctly when he knows so much about electronics?

Congratulations! Your video, Heat Shrink Self-Solder Butt Splice Connectors, has reached the #1 spot in the current Top 15 New Videos listing. This is a very difficult thing to accomplish but you managed to pull it off. For your contribution you have been awarded 2 Power Points.

This achievement has earned you your "Golden One" Level 13 Badge!

Found these on Amazon awhile back while modding my 3D printer and, since I've never really done much soldering, these seemed like a cool idea and they work great.

I don't understand what he was doing at the :17 and 2:49 marks. I mean, obviously smoking out of a bong-like device, but what's he holding / doing? Looks like a soldering implement of some sort.

Meh, padlocks are not for securing valuable property or for securing property against someone with any sort of tools at all. They are for preventing opportunistic theft. 30 seconds to defeat the lock is plenty long enough for that. Of course, that is a pretty stupid design, so good video nonetheless. If I owned one already, a little solder or permanent loctite on the inner screws would probably do the trick.

Mostly though, The lock company lost me at $100 for the lock. A traditional dial is not *that* hard to work and I'd be worried about false negatives and dead batteries even with a high-quality finger print reader. Just buy a $10 padlock at the hardware store to lock up your garbage cans, or proper u-lock or quality cable to lock up your $600 bicycle (ie, something that will require 15 minutes to defeat).

Excitement for my plans to make myself a 9 string bass with the highest string betting guitar, using one single curved back neck in the creation of a dual fretted/single 9 string/highest guitar string etc. Opposing faced, designed to accommodate the most coil pickups/hummbuckers I can fit/ make fit. Farraday caging the parts with inconel 600 non magnetic foil (aviation grade). Use non solder crimping connections, platinum cable/wire & connectors with graduating switches/transition low to highest setting etc. Built in anti surge devices, connection.

“The most important thing that happens when a new iPhone comes out is not the release of the phone, but the disassembly of it.”

Demonstrably false. The market has proven that almost no one cares about this.

When the iPhone first came out, people derided it’s lack of removable battery. Good luck finding a high end smartphone with a removable battery these days. Then there was components soldered onto the board, then the removal of the headphone socket, all of which Samsung, etc have copied*.

Outside of a vocal minority, no one cares about phone repairability. If you do, congrats, you’re part of that minority, and that’s fine. Personally, I think it’s a reasonable thing, but clearly, most people prefer thinner, lighter, water resistant phones over fixable phones.

* note: yes, Apple have copied features of droid phones too. No, it’s not relevant to this discussion.

So... dead short across the busted LED with some solder and get 11/12ths of the brightness for an additional however long until another one fails?

From what I've read when you heat up the nut from the bottom and drip/hold the candle on top the heat kind of wicks the wax into the threads, the same way that solder/flux wicks when soldering copper.

Just make sure to clean all the wax off when putting the nut back on or it will vibrate loose.
