You all have to check out these videos they are awesome. These are videos from ex techtv host kevin rose. He has left that network and started to do his own online tv shows. So far he has two out. In the first episode he builds a war spying device that can hack into unincrypted surveylence cameras. In the second episode he builds an open source dvr which kicks the crap out of tivo. You all have to check these out they are completely free and legal. (I'm actually considering building the dvr)
