@Undo I dunno if it's worth mentioning, but I'd happily offer (remote) access to Yam if it'd help. (Yam fetches question/answer data real-time, then passes it on to Pham/Gham for checking.)
So, Yam sends Smokey Qs real-time (full data) -> Smokey requests all posts made by user -> Yam query's his log; send all found Qs -> Smokey checks the Qs; report any dupes ?
@AnnonomusPenguin :P Well, can you evaluate the feasibility of an idea? Have a spoken query converted to text & sent to Wolfram Alpha for an answer to the question.
Ok. The onboard capabilities of the Arduino is quite limited so voice recognition is hard to do. I've seen shields that are $60+. I'm not sure if the Yun could do some more advanced stuff
Other than that, I think WA would have an api but not sure
@hichris123 Staking a bit, but I did a pretty easy Arduino project called Stalker Guard (3rd chapter in that PDF). It was pretty cheap and took maybe an hour.
