Re: [RDD] Raspberry2

Hi, Was curious to what this $500 device was, just a quick correction, it turns out it has its own built in power supply (115/230V 50 - 60Hz, 2W) and cable that comes out of it. Info gleaned from here but still $500 seems expensive for what it is:

Hi, I took the one that I have apart, if anyone is interested. The main chip is the TI PCM2902E It also has 4 op amps, they are all TI 2353UA's I admit that I'm a little surprised that this interface doesn't have S/PDIF connections. The PCM2902E can handle S/PDIF (as opposed to the PCM2900

Re: [RDD] Raspberry2

I haven't tried a Raspberry Pi 2, but I did get Rivendell to run on a Hummingboard, which appears to be an Israeli clone of the Pi. IT works very well. I want to use these to build 1 RU boxes I can deploy to World Classical Network stations. The only stumbling block is getting broadcast

Hi, The Pi doesn't have Audio in but if all you want is high quality output (unbalanced), iqaudio.co.uk do some really nice Pi Hats that use the internal i2c connector on the Pi (hopefully I've remembered that connector name). They did speak with me about balanced audio and the possibility

Re: [RDD] Raspberry2

If you're building 1U boxes anyway, might be worth putting a balanced audio driver chip or transformer in the box. That's what I ended up doing for a little embedded Pi "codec" I built. Ended up being far less costly than a balanced USB card though admittedly more fiddly to build. Regards,

Hi. A while ago, I saw a post about running Rivendell with succes on the Raspberry pi 2. There was some talk about uploading the image, so a lot of people could save a lot of work :-) I can't remember the person who has the image, but maybe the time has come to upload this image? Would be great!
