Neues vom Projekt "optische Bandfiltersteuerung":
Die IC-765-#TOSLINK Platine hier holt sich Stromversorgung + PTT-Signal aus der ACC-2 Buchse, CI-V per Klinkensteckerpatchkabel (nicht im Bild) und setzt die Signale erfolgreich auf Licht um.
Leider hab ich keinen 7-poligen DIN-Printstecker gehabt, daher der kreative Eigenbau 😁
Hey #FreeBSD lovers, would one of those USB-A to #Toslink adapter work on 14.x-RELEASE?
I’m considering using my #Navidrome server as a jukebox but my FreeBSD box does not have toslink output.

🤯 Building Ultra Long Range TOSLINK
https://blog.benjojo.co.uk/post/sfp-experiment-ultra-long-range-toslink
[38C3] It’s TOSLINK, over long Distance Fibre.
If you’ve owned a CD player or other piece of digital audio gear manufactured since the 1980s, the chances are highly to has a TOSLINK port on the back. This is a interface that sends I2S digital audio data down a short length of optical fibre, and it’s designed to run between audio gear & an external DAC.

![TOSLINK is a ancient technology in optical fibre terms, with a lowish data rate and plastic fibre, but consider for a minute whether it could be adapted for modern ultra-high-speed conenctions. It’s what [Ben Cartwright-Cox] has done, and he delivered a talk about it at the recent 38C3 event in Germany.
It’s an interesting experiment, but perhaps the most value here is in what it reveals to us about the way optical networking systems work. Most of us don’t spend our days in data centres, so that’s an interesting technology to learn about.

If you’ve cast you eye over any fibre networking equipment recently, you’ll be familiar with SFP ports. These are a standard for plug-in fibre terminators, and they can be had in a wide variety of configurations for different speeds, topographies, and wavelengths. They’re often surprisingly simple inside, so he wondered if he could use them to carry TOSLINK instead of a more conventional network.
And it worked, with the simple expedient of driving an SFP module with an LVDS driver to make a differential signal. There follows a series of experiments calling in favours from friends with data centre space in various locations around London, finally ending up with a 140 km round trip for CD-quality audio.](https://files.mastodon.social/cache/media_attachments/files/113/815/682/617/067/154/original/743acddccee39d8a.png)
Необычный случай с ремонтом китайского декодера аудио 5.1
Год назад я приобрёл на Авито по символической цене в 300 р. неисправный китайский девайс под названием «ЦАП 5.1 Bluetooth декодер» модели HD920Pro. Это универсальная приставка аудио, выполняющая роль mp3-плеера с USB флешки, плеера через Bluetooth (Bluetooth ресивер), звуковой карты, декодера 5.1 звука с SPDIF (коаксиала или оптики Toslink) и прочее. В данной статье я решил поделиться с читателями, пожалуй, как я считаю, необычным случаем моей ремонтной практики. Хотя, всякое может быть. Может для кого-то, кто занимается ремонтом глубже, этот случай покажется совершенно обычным.
@Nellen @lexd0g Just use a #fanless #UniFi switch with #SFP+ ports and shove some AOC (active optical cable) or matchibg modules and fibers in it - like with #Toslink...

My #diy #bluetooth to #toslink receiver built with a red led and an #esp32.
I've learnt that #TOSLINK and S/PDIF while #digital don't provide the same bandwidth for #audio than #HDMI 1.0. It feels weird though to connect any non-video media player to my #amp through... HDMI. Is there some digital standard that basically is HDMI sans #video?
This would be especially useful since while my amp does have HDMI input it is a bit... picky and despite pass-through enabled it reduces the video quality to FHD only in a setup like [source]->[amp]->[sink]. So currently I'm splitting the HDMI into video (HDMI again) and audio (TOSLINK or S/PDIF) and feed only the latter to the amp.
I acknowledge that the difference b/w S/PDIF and HDMI audio is probably not audible to me, but it annoys me in great detail nonetheless, that there seems to be no non-video connector for digital audio on par of HDMI. I wonder when we'll be connecting computer speakers to the PC via HDMI...
@max Ich habe bei #TechnologyConnections die Vermutung gehört, dass wohl mal ein Upgrade des Standards mit mehr als einer Glasfaser im #TOSLINK-Stecker (z.B. für eine bidirektionale Verbindung) angedacht war, was dann aber nie realisiert wurde. Erscheint mir soweit plausibel.
@Archie8 Apart from this secret YouTuber. (-:
@Archie8 To be honest, I very much doubt it.
The RCA and #SCART connections themselves I expect will have identical results to the naked ear. And the difference in DAC quality I expect will vary more by manufacturer/model than by generalities such as "old CD player" versus "modern DVD player".
If this were analogue versus optical #TOSLINK, that would be a different kettle of fish.
Anybody got a Toslink DAC to RCA with Bluetooth they’d recommend? #dca #toslink #bluetooth #budgetaudio
Spent the entire day yesterday trying to find a 3m long TOSLKINK cable to hook up my #MiniDisc deck to my PC. No store had it in stock, all they had was 1.5m or 1m and that just wasn't going to cut it.
Against all odds I found the only one left in a small store in my area, 10 minutes before closing time.
TOSLINK is supposed to work reliably up to 5-6m, so I see no issue with this cable being "too long" so there has to be another reason why shorter cables are more common...
Adding Optical Audio to the Raspberry Pi with One Chip
In the home theater space most people would tell you the age of optical audio, known officially as TOSLINK, is over. While at one time they were the standard for surround sound systems, the fiber cables with their glowing red tips have now been largely supplanted by the all-in-one capabilities of HDMI on new TVs and audio receivers. But of course, that doesn't mean all that TOSLINK-compatible hardware that's in the field simply disappears.
If you're looking to connect a Raspberry Pi to the optical port of your AV system, [Nick Sayer] has you covered. His "TOSLINK Transceiver Hat" utilizes a WM8804 chip from Cirrus Logic to go from the Pi's I2S audio output to S/PDIF. From there the signal goes directly into the TOSLINK input and output modules, which have the appropriate fiber optic hardware and drivers built-in. All you have to do from a software standpoint is enable a boot overlay intended for a digital-to-analog converter (DAC) from HiFiBerry.
The WM8804 is joined by a handful of passives.
Speaking of which, comparing this project with commercial offerings from companies like HiFiBerry is somewhat unavoidable. While we can't say for sure how the simple design [Nick] has come up with compares to more expensive (or even cheaper) options on the commercial market, obviously going the DIY route always nets you extra points here at Hackaday. Plus, we've always been fascinated with projects that tackle this relativity rare example of consumer-grade fiber optic technology.
[Nick] is offering his assembled TOSLINK hat for $40 USD on Tindie, but he's also made all the necessary files available for anyone who wants to build one themselves.
