MORE INFO

I found an old TV in the trash the other day, I fixed it and only then I realized that I wouldn’t be able to use it because it only had an RF input.
SOOOO, I decided that the next logical step would be to make a composite to RF converter, but since I did not have the motivation to do so, I did the next best thing, I bought one of these.
For some reason there are no potentiometers to adjust phase, I think this is very sad …
The chips havee been sanded off, so sorry I can’t give you much info except that the HDMI processing chip is made by MacroSilicon.
