    But the phono cartridge produces a very small voltage.
    Which has to be amplified.
    Which is almost always by an amplifier connected to mains current.
    So, we're back to "Amplification? Power Supply modulated by a music signal."

    That small voltage has to get from the cartridge to the amplifier.
    The cables need to well shielded if they aren't pick up stray electric field from, say, a nearby mains power equipment and/or cables.

    And the vinyl is being spun by an electric motor.
    Which is powered from the mains current.
    Which can speed up/down according to power supply fluctuations, contributing (at least in part) to wow and flutter.

    Let's bring back the spring powered gramophone !

    You are missing the point.

    The source either has or has no power supply.
    The quality of that supply determines the quality of the extraction of the information.
    Power supplies have certain common characteristics. Firstly, they are expensive, often the most expensive section of any electronic device.
    Better supplies cost even more money than cheap supplies, and the quality of reproduction is evident when costs are limited in the supply section.

    The phono cartridge has no supply, therefore those (and other) limitations do not exist. But more importantly, the difference affects the sound quality.

    I clearly stated that amplification required a power supply.

  3. Nothing to do with "vinyl" on Digital and Analog Audio's Curious Coexistence (cnet.com) · · Score: 2

    Aside from the only truly valid reason to own a turntable, which is, 90+ % of all the music produced prior to about 1990 will never be released in a digital format ... in other words it's about the software, not the hardware. It is the fundamental reason for owning a vinyl playback system, or a cassette deck for that matter. All this hardware talk is just noise. Sure, some people want better playback of these analog formats, but focusing on that is a huge Red Herring. For some reason Tech writers can't get past a focus on hardware, and that goes for digital as well as analog audio.

    But, we live in an analog world when it comes to music. It starts analog, and it ends analog (playback). A very, very long time ago I learned that with electronics, every time you make a translation ... whether that's simply recording live to tape or Digital Audio Workstation, or a change in format, or any number of ways to do a job with the electronics ... and there is always the final translation to moving air in a room, you lose something. Maybe not much, but something.

    The other thing is you use the best tools for the job. Recording on a DAW is better than recording on magnetic tape, the only real viable alternative option. Yes, you can record direct to (vinyl) disk, but that's hard and doesn't lend itself to large quantity replication, so it's a niche example. It is better than mag tape, but it's also severely limiting, an "old-school" technique, live to final mix, that was happily abandoned when multitrack recording technology came along.

    So, whatever tools were used to *create* an album, when it's final form is finished, that's your product. It doesn't matter if it was recorded, mixed and mastered on a DAW anymore than it matters that the artist used a toy piano or a concert grand to make the music. Once in finished form, then it matters how it's played back, because a vinyl record doesn't sound like a CD, and it shouldn't sound like a CD, otherwise there is something seriously wrong going on (with the CD, probably).

    So, a phono cartridge is a transducer. Like a dynamic microphone, like a loudspeaker. What distinguishes transducers from other parts of the playback chain is they are not powered devices. A phono cartridge has no power supply, it generates it's own voltage through movement. If you push on the cone of your subwoofer, it generates a back-electromagnetic force on the power amp. And so on.

    And although it's not obvious to most people, when you listen to music through a modern sound system, you are listening to the power supply, modulated by a music signal. So the quality of the power supply is paramount to the sonics.

    CD player? Power Supply modulated by a music signal.
    Amplification? Power Supply modulated by a music signal.

    But not a phono cartridge. There is a vast array of issues to deal with when you have to use a power supply driven by mains current from the wall. It would not be an exaggeration to say that almost everything in audio that has developed since the early 20th century is the story of power supply technology and ways to modulate that supply.

    So, it would be unusual if vinyl *didn't* sound different, even if the final product (the shipping software, in LP or CD or whatever form) was created exactly the same way.

  8. I think the original idea of the stickers was to keep users from mucking around in their own devices trying to fix something and just breaking it worse. So the warranty would be voided in those cases. But I am sure plenty of companies use that excuse to also block third-party repairs since they too would have to break the seal.

    Think of it this way, you take it to a 3rd party, who sucks at repairs and uses bad parts. This causes more damage to the device. The manufacture's costs to now provide warranty support now is much more costly, and frankly untenable for supporting stuff that they haven't approved.

    This is a case of a good intent from the law (allowing you to repair from anyone) going to a bad extreme and forcing companies to unreasonably support things they shouldn't have to (bad parts, poor work, additional damage that are not their fault) or even encourage outright fraud.

    I'm no fan of companies doing lock-in, but I can fully understand the reasonable requirements they want to impose for warranty repair.

    The manufacturer's warranty does not, and is not legally required to, cover damage due to an improper repair by an unrelated entity. The exemption isn't unlimited ... failure unrelated to that improper repair must still be covered ... but I don't think the scenario you propose is a rational excuse for seal break warranty refusal.

    The water resistant watch case and back should not be opened by laymen, simply because they might not re-assemble it correctly and lose that water resistant protection. I recommend you always take a watch to a Jeweler to replace the battery. You're right ... you don't *have to* do it that way, but unless the watch is fairly inexpensive ... well below $100 ... the risk vs reward doesn't really make sense.

    I have some quartz watches that are only certified to be water resistant if sent to the manufacturer for battery replacement. They are expensive (more than $1000) Swiss made brands you would probably recognize. Do I think it necessary? Not really, but the risk of damage to a watch that costs that much if the seal isn't done correctly when opening and resetting the back case, versus the $20 and a week it costs, I won't chance it.

  10. I know what I would do on Passengers Who Call Uber Instead Of An Ambulance Put Drivers At Risk (buzzfeed.com) · · Score: 1

    If I were an Uber (or similar) driver. I would just sit at the spot where the ill passenger entered, and call an ambulance for him. That means I've done the one thing a citizen is reasonably required to do given an illness situation I've come across, and takes the legal liability out of the issue for me.

    If every driver did the same, then the "problem" of people calling drivers instead of ambulances would end rather quickly.

    As for the cost of ambulance care, I don't see it as a problem. If you have insurance, that pays for it. If you don't have insurance but do have a reasonable income, you pay it yourself. And if you don't have the means to pay it, anything serious enough to require emergency room attendance is serious enough that the cost (or probably more likely, the harassment by bill collectors) is irrelevant, versus your health. The point being the ambulance isn't going to deny you service based on ability to pay.

    Where I live (Commie Medicine Canada) the cost of ambulance care is capped at about $US 280 (helicopter, air) or $US 261 + $US 1.15/mile (ground). It's possible to incur both an air and a ground ambulance charge.

  11. A lot of answers come close, but don't quite complete the "discrepancy" mystery.

    True, the torque output of a Tesla vehicle is very high at near-0 wheel RPM. True as well, it falls off as the electric motor increases in RPM.

    But the horsepower discrepancy is easy to account for.

    Dynamometers used to measure vehicle power measure torque, not horsepower.

    Horsepower cannot be measured by any device, actually. Power can only be measured as torque.

    A mathematical formula is used to convert torque (measured) to horsepower (calculated).

    Normally with internal combustion engines torque in lbs/ft x RPM divided by 5252 (the formula) gives higher numbers when RPM increases, especially above 5252 RPM where +1 ft/lb now creates more than 1 HP.

    The electric Tesla must generate huge torque values at very low (near but not zero) speeds to generate high HP at those RPMs. None the less, it is consistent with how these "engines" work.

  12. Lead Free solder (aka RoHS compliant assembly) is not universally mandated in every application, for example it's use is banned (prohibited) in most aerospace and military contracts (you have to certify no lead-free solders are used), and with NASA. Also lead solder is allowed in any automotive application. There are multiple reasons for this, but essentially it boils down to reliability.

    Modern (as in 2018 versus 2008) lead-free assemblies are much better in this respect, but there is still a difference with the smallest traces and component leads.

    For hand-assembly, there are good techniques established to do a good solder joint. A large part of the success does rely on the fact that it's hand assembled, with the care and post-assembly examination by a competent human wielding the iron. Not to be confused with a whole-board assembly which will be automated or use wave soldering or some other non-hand method.

    Heat management (for the guy asking about harming the motherboard) is necessary, but fine tips and heat-controlled irons are the norm. A good iron (I like HAKKO, but there are others) will maintain a set temperature during rest and while applying the iron without much issue.

    History tells us, and with startling consistency, that wars don't start based on who allows what, they don't play out based on who allows what, and they don't end based on who allows what.

    They start because of brinkmanship (check), territorial ambitions (check) and unexpected, often improbable and generally unanticipated (by both sides) events which lead to ad-hoc responses that weren't in the playbook devised by those who plan for such things.

    They play out in such a way that the weaker employs tactics that negate the stronger's advantages, and the stronger applies force that the weaker doesn't possess. Lord help everyone if there is no demonstrably weaker and stronger side, because then the Shit Really Hits The Fan, and for longer than everyone, often including the eventual losers, would like.

    The latter often means bigger and nastier weapons, often of a type yet deployed in battle, because ... well ... it's a perfect proving ground, there's a justification (to win the war and save {our side's / innocent civilians / the enemy's conscripted soldiers etc} lives ... and interested minds want to know how effective the thing is, and what's the weakness we need to engineer out for the next war, or this one, if it lasts long enough.

    Today we have a complex web of alliances and treaties that tends to prevent big conflicts by addressing small ones, but when the improbable and unexpected happens, that just means you get a bigger war. Throw in some widely held beliefs about the other side (one widely held by America's foes is that the US domestic population can't stand a prolonged conflict and will force political concessions to the enemy), regardless if they are actually true or not.
