I’ve purchased a cirrus logic audio card and a raspberry pi B+ (just when they’ve started selling the Raspberry Pi 2!) Anyway, I have managed to get the new card working with the Pi, I’ve still got to try and figure out a way to get the Pi to start without user intervention, that will start the mobile dongle, and start Darkice to stream to the server. My old Pi was a doddle to do, can’t think why this is different? In the mean time the on line radio link that I had been using has died, I didn’t log on within the two week limit and they have cancelled the stream, no worries I think I may have found the perfect answer here: http://locus.creacast.com my direct link is here: http://locus.creacast.com:9001/liverpool_ormskirk One thing that I have realised is that Icecast does not need to be installed to stream! just by installing Darkice is all you need, and to point the darkice.cfg to the Icecast/or shoutcast server – can’t get any simpler! So, for the next few days/weeks, am leaving the raspberry pi switched on, and I’ve got “Frank” (dummy head) in the back garden using two CCTV microphones, and the Behringer 202UC USB sound card, below.
The Behringer 202UC USB sound card costs about £20, so it’s very good value for stereo streaming, a little hissy, but not too bad, I’m hoping that the Cirrus Logic audio card is far less noisy, below.
I may try swapping out the CCTV mic capsules for some Panasonic wm61a’s, the CCTV mics are like these ones below.
If I am careful, I could remove the existing mics, and replace them with better quality types, using these CCTV devices means I can use the cirrus logic card with, or without battery power on the mics, though if I don’t use power the levels are just a little too low, but if I use them on my Panasonic PCM recorder, no need for the battery as the plugin power from the recorder works just fine.
So, don your headphones and have a listen in to my back garden, lots of birds, and activity most of the day there, if you are really really lucky, you may be listening when a bird lands on top of Franks head and gives you a bird song! It happened to me the other day, it was quite something hearing it hop about on my head and to be singing there!!! What an amazing experience it was :o)
Not much happens after dark here in the UK though!!!
Wear your best headphones!
Here’s Frank in the garden – now streaming with the cirrus logic audio card on the raspberry Pi B+
