Anyway, this insertion socket is more than strange. The ring connected to the audio signal? The switch disconnects the power section from the battery, which is at the tip?
Best regards!
Best regards!
It’s just using +9 as signal ground instead of “ground” as signal ground. There is a coupling cap so you can get away with this.
But »ground« and signal need to be reversed in phone plugs and sockets, no? Ground to ring/sleeve, signal to tip.
Best regards!

It will work like it is - but probably only off battery. If your power supply has a bunch of 120Hz ripple, it will show up in series with the desired signal.
No, but evidently I am. 🙂Am I blind?
I'm off to find a white cane, dark sunglasses, and a seeing-eye dog...

It is in the SAMS house style. Errors are certain.this insertion socket is more than strange
After watching this it feels that Brian May could have prototyped its own best amp if he'd wanted to:
Thanks for posting this, VERY interesting.
Brings back memories, including what she says about old school programming.
I started Engineering in 1969 (so about the same time frame as Brian did) and we DID program in Fortran, it was the standard in Engineering at Universities around the World.
If I don´t remember wrong, the ALL CAPS bit came simply from NOT having lower case letters available, period.
Many of the earky hobby/home computers had a similar problem.
As of the Sun orbiting the Galaxy, it´s not doing it on its own, hitting dust clouds on its path; the whole Galaxy is rotating.
Just quoting from memory, but since the beginning of time as we know it or at least since the formation of the Galaxy, it has already completed a smallish number of rotations, which I find amazing, say 15 or 30 rotation, something in that order of magnitude.
Did she say the book is available online?

Type in google...you'll find it if it's outhere.Nasa is still recruiting Fortran programmers and pay them a lot to do Fortran programming or maybe just debug old equipment that's already orbiting the Earth.
As all four Queen members originally were college students, this band might have been the most intelligent one in the rock circus. I don't know, though, if any of the four has gained a degree.
Best regards!
Best regards!
Yes, and John Deacon, the Deacy »inventer«, also has an EE degree. But did Roger Taylor ever become a dentist, and Freddy Mercury a master of arts? I dunno...
Best regards!
Best regards!
Dreamth, thanks for posting that. I knew Brian May was no fool, but I didn't know he had gone back to Uni and finished off his Ph. D. Big props to him for doing that. 👍
I think it takes a lot of strength of character for someone who has become rich and famous, to take themselves back to a situation in which they are once again a novice, and start over.
David Gilmour (of Pink Floyd) did that when he decided to learn to play the saxophone - starting from scratch - along with one of his kids, to encourage him to stick with the instrument. And then Gilmour took the risk of playing saxophone in public, in front of paying audiences; it could have gone very badly for him and he could have been mercilessly mocked by audience and critics aside, but he took the risk, and his phenomenal musicality shone through, as it always has. That man could play the kazoo and be more musical than most musicians could be with a Steinway, a Stradivarius, and the entire Philharmonic behind them.
And Brian May did that also, when he took himself back to graduate school. As one who has been there - grad students are the lowliest of the low, they do all the work and get none of the credit, and at no other time in your entire education is your fate more vulnerable to abuse by one single person - your graduate advisor. Pick the wrong one, and your life will be hell for many years.
Uppercase characters only, because those used to be all that was available on the "line printer", which lived in the air-conditioned room with the mainframe, and printed out on expensive fan-fold perforated paper.
There are 26 English uppercase alphabets, plus you need ten digits (0 - 9), plus basic punctuation(,!,?, ., and so on). If you use a 6-bit number to represent each character, you can represent up to 64 distinct characters; enough for everything listed above, with a few left over for other purposes (linefeed, carriage return, et cetera). Back when every extra bit of data storage cost a lot, uppercase-only saved a lot of money and complexity.
We were taught to only write our FORTRAN code between columns 8 and 72 of each line - otherwise errors would occur ( http://www.math-cs.gordon.edu/courses/cs323/FORTRAN/fortran.html )
IIRC FORTRAN IV didn't even have an if-then-else structure, or a while() loop. All it had was a "DO" loop, and the infinitely-abusable "GO TO" statement. A perfect way to write "spaghetti code" in which the control flow became so tangled that nobody else would ever understand how your program worked. If you were unlucky, you would also not understand what your own code was doing.
Clearly FORTRAN IV was designed long before the concept of structured programming ( https://en.wikipedia.org/wiki/Structured_programming ) had been invented. I learned about structured programming from library books, and used to indent my code, construct blocks of FORTRAN IV code that behaved like if-then-else or while() structures, and so on. My crusty old programming teacher did not particularly like the fact that I was doing stuff that she had not taught us, but later on I taught myself C from Kernighan & Ritchie's famous textbook ( The C Programming Language ) - and those structured programming concepts really helped me.
In grad school, many of my friends were still using FORTRAN, though they were newer versions of the language (FORTRAN 77, FORTRAN 99). There were decades worth of irreplaceable scientific code already written in those languages, the collective work of hundreds or thousands of the smartest individuals who ever lived. No way that was going to be chucked out, so new code continued to be written in FORTRAN, so that it could continue to use the work of previous geniuses.
A lot of programming these days consists of "If button A is clicked, then open menu B". This sort of "dumb" programming can be done in just about any language by just about anyone with a couple of functioning brain cells, so these days, languages ebb and wane in popularity constantly. One week everyone is excited about Rust, the next its Ruby On Rails, the next its Microsoft .Net, whatever the heck that is.

I came along nearly twenty years later, but the university I went to still only had one ancient mainframe that only "spoke" FORTRAN IV - and that's what I was taught in my very first programming course....we DID program in Fortran, it was the standard in Engineering at Universities around the World.
