DrBouvenstein posted:Is that partly because, on average, most young people in general can hear a higher frequency range than older people? So it might part "old people like the sound, as far as they can remember what it was" but mostly "they literally can't hear the more annoying frequency." England. Tom Scott mentions them in the video you quoted. And he mentions that he could hear them until he was 30.

When i got it 10 years ago, they weren't terribly valuable, mostly below 100 euro for the 4 track 9,5cm/s model with DBX noise reduction. For me, the worse quality is the point because I fuckin love stuff that sounds like this. https://youtu.be/e_8s48-hHvc Yeah yeah I know there's plugins that emulate the tape sound but it just feels wrong and not kvlt at all to do it that way. It makes zero economic sense though given the rising cost of tapes and I'm not sure how long it would take me to get sick of it and want to move to a DAW. edit: Wondering how good (by my standards) the sound could be if I just recorded digitally and sent the final mixdown out to a cassette deck olives black has a new favorite as of 04:30 on Apr 11, 2023 |

I might be wrong but I think it's actually the flyback transformer whining and not the tube itself that puts out the high pitched whine. I can still hear it at 38 in the same room as a crt TV/Monitor but when I was a kid I could tell when the zenith console tv downstairs was on sitting in my room.

Both the flyback and the horizontal deflection coils can produce the whine. Both are powered with the line frequency signal of (in 50hz pal regions) 15625hz

At a job I once had we had monitors that would break down in such a way they would emit a high pitched whine that apparently only I could hear. It was frustrating explaining to my bosses that I was getting headaches and nausea from faulty equipment and couldn't work, especially considering my job involved listening to things.

my turn in the barrel posted:I might be wrong but I think it's actually the flyback transformer whining and not the tube itself that puts out the high pitched whine. Yes, electronics that switch at audio frequency can generate sounds via as the magnetic fields in coils and the electric fields in capacitors change. Though I've heard that capacitors usually only start making hearable noise if they're failing. In any case, coils share a bit in common with magnetic speakers and capacitors - especially ceramic ones - have a bit in common with piezo speakers. You especially hear it in DC-DC converters (like the flyback converter used to make the high anode voltage for the tube's electron beam) but anything switching at a hearable frequency can potentially make noise if the signal goes through coils or capacitors. Pretty sure nothing in the tube should make a continuous noise. Maybe if something fails badly there could be arcing or something, but not during normal operation.

Books and drawing things by hand are both outdated. And I found a book about drafting from 1996, I got for free during a library cleanup around 2005: It starts with an errata printout page about the new EN10025 names for steels, which is an actual example of failed technology afaik.  I really like the strange combination of basics and advanced info: What is pen? what is compass? what is protractor? what is Oberflächenangabenschablone? It is a stencil for surface condition markings.  Stencil for isometric and dimetric distorted things. Stickers with symbols as an alternative to stencils. Some kind of hand held plotter.  I think there was also a lego technik version. Found the pic of the catalogue:  How to fold paper and draw a line:  How to write letters:  How to find the middle of a line: How to draw two rods touching each other:   NC without the first C. Which means you need to write your own G-code. The next page has an example g-code listing for that example object, but the book has no general g-code reference section.  A CAD workstation needs an high end PC with at leas 8MB of RAM:  Actual failed tech, android showed me a document scan to google drive button while I was making those photos. It changed the photo to look like this:

IDK I've worked in international industry since 2005 and that looks like what every plant and wholesaler uses  Sometimes you need to get like special stuff from Japan or something and they do their own thing. And then you have old neck-bearded fuckos who have spirit-copied lists from the seventies because Moscow never called them and told them to get with the times.

Man, I loved manual drafting with a drafting machine. Just drawing what was in the textbook was just a problem solving exercise. And single stroke gothic is no joke. My dad was a draftsman for 30 years, so he went from by hand through a couple versions of different CAD software. He was pissed off when he had to learn AutoCAD at one point. Which was a significant change from the bespoke software they used before (as he relayed it to me - I have doubts it was so special).

I have one of those NC scribers I found on the roadside sorry for the crummy old photo  Mine needs new belts and has a dead lcd but when I first picked it up I could put a pen in the holder and make it write what I typed on that wacky alphabetical keyboard, all up it weighs about 13 pounds due to there being a great big honkin power transformer inside the briefcase style base station.

In todays freight from a dude that likes to send me stuff to fix: I LOVE the asthetic of this model with all the buttons all over the place. And bonus is it does both sides and RF AC3.  It's got an audio problem (probably with the AC3 side), and I'm unsure if this is a gift for me or I have to send it back. However this guy hates money when it comes to shipping stuff so also included an OG Xbox jsut to add to the wall I already have (and dump save/DLC data for the Insignia project)

I went into a small rabbit hole of looking at vintage cassette players on eBay and take a gander at this fella': Ok, nothing special, portable cassette player with built-in AM/FM, see it all the time. Wait, the gently caress is this?  The AM/FM functionality is from an INTERNAL MODULE that goes into the tape slot. Oh, but wait...does it take a tiny battery? And there's no magnetic head thingy like on those popular CD player cassette adapters from the 90's, so how does that work? Well, you can see small contacts on the left side of the AM/FM module, and in this photo the corresponding power and audio contacts on the interior of the player:  Pretty clever...I guess? Also...uhh...maybe DON'T include this close up of the nasty AF original headphones?  Edit: gently caress it, I bought it. Who knows what I'll do it it, lol. Maybe just occupy a spot on a shelf, IDK.

And I still find those magnetic cassette adapters magical even though the technology is surely super simple. That kind of thing is many times cooler than any latest bluetooth things or whatever the latest wireless innovations are.
