i have also seen that playstation adapter for sale, bout 11 euro. (~11$)
I was wondering, can this adapter also be used to convert the video signal to rf for a tv? i have tried the videorecorder method, but this cuts the rf signal after 5min. I set up a 555 timer circuit to "rewaken" the videorecorder by pressing "stop" every ~4min, but this is annoying as the "no cassett" text comes up every 4th minute. I will have a look for a pin out for that playstation adapter on google.
