From time to time i get obsessed with non-stationary audio streaming, esp. in the context of the radio aporee continuous stream. As you may know, this station plays random selections of the 20000+ recordings from the aporee soundmap, but also reacts and interferes with listeners, activities in the field and a couple of live microphones from the locusonus project.
The broadcast box is one of the experimental tools to engage with sound in public space, it directly hooks onto the current broadcast and allows to play inbetween places, situations and archive recordings, right where you are at the moment. However, it's quite a bulky bunch of gear to carry around.
This setup is he latest of my experiments in that field. The unit left is a Raspberry PI, a little 40€ pocket size computer running Linux, connected to a USB battery which lasts for a day, and an Olympus LS5 recorder connected to the PI via USB. The stick attached to the PI is an UMTS/3G modem for mobile Internet access.
In short, this assembly is a complete mobile radio broadcast unit, which allows to send live sound in crispy stereo to radio aporee (or elsewhere), on-the-go. Of course, without a network the whole thing is pretty useless...
I still have to do some elaborated tests, and have to improve reliability, but the concept already seems very promising. If you are interested in tech details, let me know. tbc.
edit Sat. Nov. 2nd :
today i did a short test while washing my stuff in the laundry at Ohlauer Str, Berlin Kreuzberg. it worked pretty well it seems, got some feedback from listeners. with the stream2archive recorder on aporee.org i made two 15min. snapshots of "the show":
