I haven't been able to find PCB schematics; there's stuff here but I don't think that's it? https://support.teufel.de/hc/de/articles/26524120330258-MYND...
Why not? The download definitely contains files for defining PCBs? Although it is a bit misleading to only call it CAD.
Not unusual from my experience either and it also makes sense: PCB design is a form of Computer Aided Design after all.
if a rich audiophile replaces his speakers every year with the latest and greatest, and his old speakers get passed down the food chain to other audiophiles with lower budgets, what falls off the other end of the chain is a very old speaker which whose carbon foot print has been amortized over 10 years or more, and a better listening experience for everybody in between, and perhaps even speakers for people who would not otherwise even have them who picked them up at Goodwill.
also, a healthier industry with more employment for folks who won't have much employment if they only sell a pair of speakers every 10 years.
And repairability just means that the industry can move people from manufacturing to service and support.
>There's just a handful of audiophiles that would be replacing their speakers every year
then the carbon footprint is negligible also, which is what this discussion is about, not total sales of high end speakers
but if you were a more flexible thinker, you would have noted that the explanation I gave works at any level of the product stream and it illustrates how economic activity works "at the margin" all the time; the carbon footprint argument I'm explaining against did not take this into account and gave an incorrect picture of the carbon situation.
"at the margin" is a related idea to differentials/derivatives in calculus, with a mix of brownian motion or statistical mechanics. Consider the idea that "the economy is so bad, PhD's are driving taxis". If a university opens up in that town and hires a bunch of PhDs, they wouldn't be driving taxis any more. those jobs would be filled by other people who used to be doing other things, and those jobs would in turn be filled. This is not Reagonomics, it's economics.
Reagonomics doesn’t work because the rich hoard wealth, use leveraged money to keep their hoard rather than it trickling down, and use their hoard to influence policy and the social environment against the working class.
Electronics also don’t trickle down when you toss your old phone in a drawer rather than passing it on. Or when software updates make it unusable after 3 years. Or when parts (battery, screen glass) aren’t replaceable. Or when social cache is attached to new electronics but not older ones.
So the existence of high end audio products that CAN trickle down doesn’t mean they ARE trickling down.
people sell their old cars because their economic value is high and storing them is non-negligible expense-wise also. The economic value of older phones is frequently low, in the drawer they go. People who buy a new latest greatest high end phone every year do not have a drawer with 10 old high end phones in pristine condition in it.
you are engaging in "motivated reasoning", but your motivation is to "plz plz plz find any way that socialism is a good idea, or at least reinforce the populist ideas i have about wealth". Trickle down is a description of an economic thing that happens. You've latched onto those words because it sounds like "a trickle" and that's a bad sounding thing when your goal is taking away Elon Musk's money.
The Reagan years were economically extremely good. Economists are interested in debating how much his tax policies led to growth, how much was putting the oil shock of the 70's behind us, etc. But it's an honest debate. The points you raise point to you spelling his name Ray-gun, a non serious approach to economics.
Elon Musk "hoards his wealth" because his wealth is bound up in shares of his companies. Tesla and SpaceX are valuable because of what the market thinks of their economic activity. You are engaged in a dishonest analysis of the ledger when you go down one side and take Tesla's economic activity as a "given" that's good for people and that's good because people are entitled to that, but then down the other side and say "he's hoarding wealth, economics doesn't work!"
as I pointed out before, I will point out again: none of this helps you to misunderstand what happens wrt the carbon footprint which is what I was talking about.
Yes. But is that part of the natural order of the universe, or a factor of design. Because some phones have better or worse resale value, I believe it’s a factor of design - and therefore something we can control.
> Trickle down is a description of an economic thing that happens.
No, it’s a description of failed economic policy that has made the rich richer at the expense of everyone else.
> You've latched onto those words because it sounds like "a trickle" and that's a bad sounding thing when your goal is taking away Elon Musk's money.
I mean I’m not going to deny that would make me happy, but it’s also not really what I’m talking about here. I’m talking about the design of products for longevity to minimize their environmental impact. The intersection of this and capitalism is that capitalism rewards consumption and extraction, not sustainability. And the word “trickle” isn’t actually the problem here - the problem is wealth inequality has gotten exponentially worse since the idea of making the rich richer to help the poor was invented in the 80s to scam people into enriching the rich.
> Tesla's economic activity as a "given" that's good for people and that's good because people are entitled to that, but then down the other side and say "he's hoarding wealth, economics doesn't work!"
Trickle down economics DOESN’T work. Economics works, but it’s just a description of what’s happening.
But to directly address your point: If half of elon’s wealth (in the form of tesla shares) is transferred over the next five years to all tesla workers - do you genuinely believe that tesla will create LESS economic value? Can you point to some specific thing that is harmed besides elon’s ability to buy elections?
The people who do the work should get a larger chunk of the profits from that work. Yes that’s socialism. Use it as a slur all you want. Will a little sliver of socialism fix sustainable product design? Probably not - which is why it wasn’t what anybody was talking about here except you.
that's another way to sell more than one speaker every 10 years.
As much as I applaud the idea behind the MYND and going only by the pictures from the article: It’s not a beauty.
The partially filled holes on the front make it look as if it has already accumulated some patina. The armchair designer in me can’t help thinking: If you want to go for the gritty look, do it all the way, otherwise keep it clean.
One of the biggest things I’ve learned is that the “clean” and “minimal” look that we associate with high end “well designed” products (think apple, teenage engineering) is almost completely opposed to sustainable materials and design.
The more minimal your design the more it shows blemishes. The more you see blemishes the more parts will be rejected and scrapped during manufacturing.
Similarly, the most sustainable materials to use are waste products of existing manufacturing - offcuts or upcycled/recycled scrap. But those will have inconsistent finishes that will show on minimalist designs.
I think an important step in actually moving towards ethical manufacturing is a change in aesthetics - so markers of sustainability are markers of cool / “good design”
I’m not sure that is why the panels have partial holes - but it might be a factor.
My Google Home speaker (early version) is getting long in the tooth and has become flaky.
It's still in preview.
