When I finally get my RasPi I'm hoping to use the 5v power supply that my TV provides via it's UHF antenna connection (I think it does this for TV mast signal boosters). I want to do this as I only have 1 mains power socket behind my TV and don't want to have any more mess there (it's wall mounted).
Has anyone managed to do this? I'm guessing if the TV can provide enough current @ 5v then I should just be able to hack together a UHF connector and an old micro USB connector. Any thoughts?
