HELP! Noise Reduction

[Synapse]

Hi Guys,

While waiting for my Adafruit display to arrive, I worked on another project. I will put a post about the project when I'm done. Everything was working fine until I plugged into the TV, the image was blurry and there was hissing and popping in the audio. I assume that this indicates that I need to filter the signal, as it is passing through several different wires.

The RCA signals are bring pulled from test pads 24, 25, 26 and 6 (GND) on the bottom of the Pi. I am using a model B+. I know very little about signal filtering, so please explain as though I am a total noob!

Thanks,

Could you post a clear image of just the board you're wiring the pi into, front and back please.

You might be just better off bypassing it altogether and just wiring straight to a RCA port, or of course you just wire up HMDI!

Aside from a few blobs of solder, I am already practically wired directly to the port.

OK, I'm guessing you'd like to use the original av cable for the NES, if that's the case, I don't think I can help you. I think the the audio and video from the pi would have to be run through modulator before outputing from the the NES.

[spoiler="Other Solutions"]The first option I would suggest would be this.

If you wanted to maintain a certain amount of classic nostalgia and use composite, then I would suggest using a cable.

Good luck on the build, I'm looking forward to seeing the final product.
