Y'know, I don't think that's enough to make any significant change. It takes more than money - it takes generations. Nothing will change until things get so bad that the comfortable (I assume they're comfortable if they're not engaged) majority get involved at all levels. I'm not pessimistic..
I know it's probably sacrilege, but I avoid the need for one of these by grinding half a dose, tamping a bit then grinding the rest and finishing the tamp. I'm using a Breville Barista Express so couldn't (easily) use one of these even if I wanted to.
I'm curious how you retain the magnets in it? Are they printed in, or mechanically added later? (I know very little about 3d printing, this just came up in my top-6-hour feed)
Your boiling water analogy does not fit - water boils at 100°C (depending on air pressure). It's like the digital signal - boiled/not-boiled, on/off, 1/0, etc.
The output of a DAC (Digital to Analogue Converter) is a line level analogue signal and this signal has an amplitude (voltage) that can be controlled. I'm not a software or audio engineer so I don't understand how, but my reading and own testing supports this.
My own simple test: I have a Google Pixel 4a and an Apple USB-C DAC (dongle). If I use headphones connected to either the phone audio jack or the DAC and any "normal" music player I can listen at full volume - it's loud, but far from uncomfortable. If I use USB Audio Player PRO and configure direct hardware access to the DAC I cannot listen at full volume - it's too loud.
I think Kodi was amazing when it was XBMC and the only real option. It seems to be falling behind now though :-( I moved to Jellyfin a couple of years ago.
What you're saying makes sense, but I can't believe nobody has bought up the fact that a lot of our phones are constantly listening for music and displaying the song details on our lock screen. That all happens without the little green microphone active light and minimal battery and bandwidth consumption.
I know next to nothing about the technology involved, but it doesn't seem like it's very far from listening for advertising keywords.
No - I know the difference between a DAC and an amp. The Android (or, maybe it's just Google Pixel devices, I can't recall) audio subsystem limits audio output. My phone max. output is about 800mV. I believe they assume all output is going to earphones and they're trying to protect your hearing. This happens even if you're using a USB DAC. But, there is an app called USB Audio Player PRO (the may be others) that can bypass the Android audio subsystem and send output directly to the DAC and thereby get the full DAC output - typically around 2V.
Currently no virtualisation at all - just my OS on bare metal with some apps installed. Remember, this is a single machine sitting in my basement running Samba and a couple of other things - there's not much to orchestrate :-)
Since you mentioned the "power" of an external DAC I'll add that my experience has been that android will still limit the output unless you use an app that works directly with the DAC. Last time I checked the only option was paid.
Wow - I thought docker was overkill for a home server and you've gone kubernetes! I guess if you use it for work and that's what you're comfortable with?
Because it seems overkill for a home server. Up until recently all I ran was Samba and a torrent daemon. Why would I install another layer of overhead to manage two applications on one server?
Yeah, I get it now. Just the way I read it the first time it sounded like you were saying that was a complete command and it was going to do something "magic" for me :-)
That's exactly how I feel about it. Except (as noted in my post..) the software availability issue. More and more stuff I want is "docker first" and I really have to go out of my way to install and maintain non docker versions. Case in point - I'm trying to evaluate Immich so I can move off Google photos. It looks really nice, but it seems to be effectively "docker only."
I understand I've got LOTS to learn. I think I'll start by installing something new that I'm looking at with docker and get comfortable with something my users (family..) are not yet relying on.
A store near me (Canadian Tire) has them linked to their app - you find what you want in the app, go to the aisle listed and tap "find this item" and the LED flashes.
