So now you can re-create that iconic room from The Matrix III for your Tecchie Cave!

If in the US: Just remember UHF and VHF channels are in licensed frequency ranges... i.e. you can be fined for transmitting on a licensed fx without either licensed equipment, station, or operator depending on the frequency.
Pretty sure that cheap transmitter hasn't been approved for most regulated countries...

Why only CRT TVs? Surely this would also work on older flat screens that have analog tuners.

I did this about a year and a half ago using the same hardware. I wrote a webservice/app that lets you use your phone like a TV remote, where changing channels loads up different playlists. https://github.com/ssshake/pi-uhf-tv-station

As long as your transmitting power is not more than 4W you're in the clear. I don't see pulling 4W off of any pin on a Pi for more than a few seconds so as long as you don't use an external power source you should in the clear.
