Far from being mere toys, unmanned aerial vehicles will eventually be used for applications which were once only features of science fiction, thanks to research being carried out at the University of Luxembourg.

DIY stalker device uniquely IDs people by tracking radio signals they emit.

The research pair first envisioned Snoopy more than two years ago to underscore how much data could be gathered by a collection of devices that are within the capability and budget of a die-hard hobbyist.

With a price tag of under $200 for the Snoopy spying node and $1,650 for the optional flying drone, the resulting proof-of-concept is even more instructive in the post-Snowden world that has since emerged.

If Snoopy is the product of a researcher duo working in their spare time, just think what the National Security Agency, GCHQ of the UK, or Israel's Mossad can do.
