Re: TinyTOSLINK (digital audio output) now for B+, too

Wed Sep 06, 2017 9:19 pm

Hi,

first of all I would like to thank you all for the good work and sharing knowledge!

My new Pi Zero W should serve as a music player. From my first research I thought I just molder a Toslink transmitter to the correct pins and configure Raspian... Poor research! (Btw: Why doesn't that work???)

But reading this thread gives me hope for a solution. Is this TinyTOSLINK available for Pi Zero W? The "wired" solution (like in http://abload.de/img/rev_b_pluse7oi5.jpg) suits the purpose, the perfect PCB is not necessary.

BNC would be as good.

Thank you very much and best regards
vylpi

Hi vylpi

Connecting a Toslink transmitter directly is not really possible, because you need a very accurate timing for the optical signal.
The Raspberry Pi has a Audio interface and you just need a sound processor which converts this to the optical signal.

If you buy my board it should fit onto the Pi Zero W like on a normal Pi B+ (because the header should be the same).
You just need to solder the header onto your Pi - if you want I can also include a header for you to solder.

Is there a way to disable tinytoslink via software?

Thu Sep 28, 2017 3:30 pm

I have a receiver that only has 1 digital input, so i connected my TV and tinytoslink with a Y-Splitter to the receiver.
The tinytoslink module emits light all the time, so I cannot hear the sound of my TV.
Is there a way to disable tinytoslink by software, so I can disable it when I want to watch TV and enable it again if i want to hear music?

Hi,

what OS do you use?
On OpenElec and LibreElec the transmitter shuts off when there is nothing to transmit.

I had a similiar issue, but didn't want tu use a Y cable or a simple switch with a remote.
So I also designed a optical audio switch (with automatic input detection, 4 or 7 inputs and some optional nice features).
You can take a look at it here:

Maybe you are interested in something?

Best Regards
Benjamin

That looks awesome, but I guess that's a little too much for just two inputs.
The TV does not emit light when it is in standby.
I'm running osmc on my raspberry pi. I'm using shairport-sync to listen to music.
When I restart the Pi, the transmitter shuts off when there is no audio input just fine. But if I leave it running for a few days, something causes it to emit light.
I stopped the shairport-sync service, but that did not stop it from emitting light.

Edit:
You should have told me about that a few weeks ago, I just bought some sabre dac.
If I still were in need of a dac, i would definately buy your board.

Hi,

the cheapest version has 4 inputs and 2 inputs wouldn't be cheaper - and maybe you have a 3rd device sometime in the future ;)
with the prioritized inputs on this switch it would definetely work for you
if we make a private order I can make a special price for you (Tindie charges fees)

maybe you should try LibreElec - maybe this works better for you?
I'm only using LibreElec and the transmitter always switches off.

Best Regards
Benjamin

I see If I can sell my DAC, if someone buys it I will get right back to you.
Maybe shipping can get a little cheaper as well, since we're neighbours (Hallo aus Deutschland :D )

So finally my Pi Zero W is a neat little Music Player:
Software:
- Raspbian
- MPD controlled via MPDroid on old Android Phone
- YMPD (just for testing)
- Music on a network share

Hardware:
- Pi ZeroW
- TinyTOSLINK PCB
- Oak wood
- High End optical cable, Camtech DAC, etc.

Thank you very much, Benjamin!
