A little bit of fun. I took a cheap greetings card audio system and wired it to the Imp!
See it in action here: http://brendandawes.com/blog/walkietalkie
Does the audio streamed through IMP or only the trIgger comes via IMP?
Cool experiment btw 
It’s just being used to trigger the audio. I’m sure it’s all possible to stream audio but it would need a lot more work and probably a bigger brain than mine.
Nice demo, Brendan - simple but demonstrates well how the imp can be utilized. We do plan on implementing audio processing but, in its current state, the imp is not quite ready for real-time audio application. For more discussion, see this thread.
Great stuff. I think the audio processing stuff is really interesting, and it’s also great to read that thread to see all the future development plans. With my Walkie-Talkie demo it was more about hooking up cheap everyday components as I’m kind of in to that idea – in this case a greetings card sound module, inspired by the likes of the hitech lotech group at MIT.
