(Demonstration by Servando Barreiro)

Föhnseher rises from the scrap heap of analog TV.

Unlike other televisions, Föhnseher captures and displays images downloaded by people on surrounding local wireless networks.

Phones, laptops and tablet computers all become broadcast stations for this device, replacing the forgotten television towers of old.

    Will you share the device? I can imagine a huge redundant technology fest....

    I will once I've standardised the extra hardware needed. What I have in this first version is really not so easily reproduceable/space-friendly. I want to look into a small ARM board next and a more compact solution for the signal modulation.

    julian! i love your work. how does this work? do the downloading devices need to be on a specific wifi network? or are you really prying into any wifi network unlucky enough to be nearby? did you add a VGA input to the CRT yourself? very curious.

    Thanks for the kind words!

    In the current implementation it watches just on one (open) network. It is perfectly possible to sweep all channels, looking for traffic on other networks, but the TCP stream would be broken, resulting in the occasional partial or broken image. Partial images may be a nice addition, in fact.

    As regards to the VGA signal conversion: I had to go from VGA->SVideo->[modulator box]->TV(RF).
