Weekend Project: Arecibo Decoder with P2

In 1974 a message was sent to potential extraterrestrials.
The good news for aliens is: With the P2, this message is easy to decode.
An advanced alien naturally has a VGA monitor.
Unfortunately I can't attach the wav file, probably too big.
I detected the 941 Hz with the Goertzel Algo and converted it to a VGA image.
Setting the correct trigger threshold requires some patience. The rest is easy.
So if I can do it, the aliens can do it too.
