So I have had this little 5" LCD sitting around for about a year now, and a battery to power it too. I was originally going to make some project with it but, well lets just say it didn't work out. Anyway I want to make it into a TV that I can use anywhere in the house I can get a cable wire, but there is no way to change channels on it, and it only has composite input. A friend said a TV tuner like a VCR would work, where can I get something like that but REALLY small? THX!
