"Smartifying" my hi-fi system

This is like a 21st century version of those cassette tapes with 3.5mm jacks; the ones you could use to play CDs from your Sony discman through your car&#x27;s stereo.<p>Great work OP!

Hope this comment section doesn&#x27;t discourage anyone from posting cool hacks like these on &quot;Hacker&quot; news.

To the people dismissing this work as a yak shave you are missing the spirit of the article. To me it shows creativity, out of the box thinking, the will to solve a problem and actually doing it and the ability to explore a field which was previously unknown to the author and yet come up with a solution.<p>Besides that it contains a wealth of information on related and dervative topics for future reference. Great stuff, the world needs more of this.

This is quite a yak shave. You can run Spotify on one computer and have it output to speakers connected to another computer using Spotify. Remote control. I do it all the time.<p>So you can run Spotify on your desktop, and control it from Spotify on your work laptop.

&gt; all I want is to play Spotify using those speakers<p>What was wrong with plugging the laptop into the hi-fi system via the 3.5mm port or a USB DAC? Maybe I don&#x27;t understand just how dumb this hi-fi system is..

I think the interesting tech here is that you can stream some kind of arbitrary data (in this case Spotify ) onto a USB device and present it as files, possibly executable. Sounds like something the spy world uses or wants.

This is a great hack! I’m disappointed to see the negativity in the comments here; it’s a clever personal solution.<p>For those who want to hack a <i>little</i> less, I’ve found that a HiFiBerry[1] on a Pi works excellently for me[2].<p>[1]: <a href="https:&#x2F;&#x2F;www.hifiberry.com&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.hifiberry.com&#x2F;</a><p>[2]: <a href="https:&#x2F;&#x2F;blog.yossarian.net&#x2F;2022&#x2F;11&#x2F;07&#x2F;Modernizing-my-1980s-sound-system" rel="nofollow noreferrer">https:&#x2F;&#x2F;blog.yossarian.net&#x2F;2022&#x2F;11&#x2F;07&#x2F;Modernizing-my-1980s-s...</a>

I do like it. I have run my old ARCAM AVR from the optical out on my TV for nearly a decade. I can use the TV&#x27;s media player, or use the TV as a second screen &#x2F; audio device for my desktop.<p>In the latter case, Voicemeeter makes it possible to fill the house with near-perfectly synchronised sound.<p>In the former, I can throw and control files from my mobile, using Bubbleupnp.<p>Both good. But there is a big part of me that wants the amp to work on its own. Smart is most definitely not always the answer. Being unable to fiddle with a thing from your main devices can be a big QOL win. And frankly, one afternoon screaming at an Echo Dot was enough. Invasive, demanding, awkward, restrictive.<p>I feel that in many cases the big wins from modern tech came over a decade ago for me.<p>I&#x27;ve dropped my interest in most smart &#x2F; streaming devices - too much choice, too much distraction and advertising. Smart lightbulbs, I will make an exception for - far easier than fitting old style dimmers.

I&#x27;m not sure what hifi system OP has, but another way to do this is by emulating the iPod remote mode over USB. It saves a bunch of trouble with emulating files. Denon&#x2F;Marantz products have supported (and i believe still do) for a very long time

This was what the Google Chromecast Audio was amazing for. £30, a fibre optic output. Then they killed it. I still have one and use it every day, and they’re fairly sought after so prices on eBay are more than twice the retail price

Why not just load up the Spotify client on the desktop PC and use the Spotify client on the laptop to play on it through Spotify Connect? It requires Spotify Premium but it works great. Kudos for finding something else that works!

This is very cool, well done! What struck me the most is that I read your problem description and thought &quot;I&#x27;d do something with some electronics&quot;, and then really liked how many different solutions there are when you&#x27;re trying to solve an entirely pointless problem in the most impractical way possible.<p>I really want to start some sort of hackathon, like the &quot;stupid shit no one needs and terrible ideas&quot; hackathon. I love this kind of hacking entirely for the fun of it, and this reminds me to write up my bubble drone. We&#x27;ll done OP!

So it&#x27;s a USB &quot;mass storage device&quot; that doesn&#x27;t actually store the music on it, but gets it from spotify instead and presents it as a file to the USB host. Kinda neat I guess.

I thought more and came back to say that you might have considered the following setup:<p>Employers laptop -&gt; (if newer laptop with no 3.5mm audio, cheap USB DAC) -&gt; 3.5mm analog -&gt; hifi analog input -&gt; your ears<p>I wouldn&#x27;t waste money on an expensive DAC. As I mentioned above... 320Kbps lossy audio. No point in a crazy DAC. No point in going through hoops to use your existing DAC.<p>Can confirm yak shave as commented by another. Full yak shave. I looked it up.

This is... something.<p>Or you can just buy one of these: <a href="https:&#x2F;&#x2F;www.wiimhome.com&#x2F;wiimpro&#x2F;overview" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.wiimhome.com&#x2F;wiimpro&#x2F;overview</a> (review: <a href="https:&#x2F;&#x2F;www.theverge.com&#x2F;2023&#x2F;2&#x2F;8&#x2F;23571271&#x2F;wiim-mini-multi-room-streamer-chromecast-audio" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.theverge.com&#x2F;2023&#x2F;2&#x2F;8&#x2F;23571271&#x2F;wiim-mini-multi-r...</a> )<p>It is going to let you stream everything on virtually any service, it has AirPlay, Spotify, Bluetooth, whatever... and it will output analog using the internal DAC or you can choose to hook up an external DAC if you like.<p>It&#x27;s cheap, there is a simpler version, and a more feature rich version.<p>Or if you walk in to a HiFi store you&#x27;ll probably walk out with one of these <a href="https:&#x2F;&#x2F;www.bluesound.com&#x2F;products&#x2F;node&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.bluesound.com&#x2F;products&#x2F;node&#x2F;</a> (but IMHO the WiiM is better).<p>And if you really want to go and put something OSS together then there are Raspberry Pi equivalents.<p>I am very into good speakers and a good traditional amp and keeping my DAC separate and my streamer separate from that... but it doesn&#x27;t have to be hacked together (though knock yourself out if you so desire) and it doesn&#x27;t have to be &quot;audiophile&quot; expensive either. Every good stereo that served you well for many decades can continue to serve you well with a cheap external streamer.<p>The only place where audiophile tendencies might kick in if you really want your lossless 96&#x2F;24 playback (why? you can&#x27;t hear it!) and you read up and discover that actually your digital path was capped somewhere along the line (probably an older TOSLINK component at 48&#x2F;20)... but still, no-one has to do this, no-one will hear the difference.

I know I’m gonna get downvoted because this is HN and obviously massive kudos for engineering something amazing… but seriously this is a massive sledgehammer to crack a walnut! Just connect a phone to the Aux jack and run the Spotify app…

fun read!<p>also my research says you can get an airport express gen 2, which has a 3.5mm audio plug. you can use airplay 2 to stream media to it and whatever speakers you have plugged into it.<p>just bought a pair on ebay for ~$30 per

A much easier way to achieve this goal is to get an FM transmitter - a device that reads audio from Bluetooth or minijack and broadcasts it at low power over wideband FM. They cost around $10-$50.

I&#x27;m glad you enjoyed this project.<p>Spotify max bitrate is 320Kbps compressed lossy audio.<p>If the physical buttons on your player induce euphoria with every touch and this feeling in no way is lost to hedonic adaptation... This project could be defended in the court of hackernews.<p>It sounds like you learned a lot during this. That is good. I am glad for you. I have done similar things. They made similar levels of sense(arguably approaching none).<p>Not for nothing, if you actually care about the &#x27;fidelity&#x27; part of hi-fi... Meh... I&#x27;m glad you had fun bro. I wish I could waste such time without endless guilt. Maybe in another life.

You have to be smart to be so &quot;dumb&quot;. I would have done a pi w with an audio board but you do you.

Title is a little off - I was expecting something like a micro controlling the serial ports on some receiver to tie into a smart home but this is pretty neat. Honestly I think I&#x27;d rather just setup a Spotify compatible casting endpoint though.
