Nintendo AV mod testing /
AV modausten testailua:
KESKEN / UNDER CONSTUCTION!!! > Last update / Päivitetty: 16.4.-13 <
Näitä AV modauksia kun tuntuu olevan vaikka minkälaista ni päätin tehä kaikki ja laittaa tulokset tänne.
80sFREAK style:
Video + GND > PNP Transistor > 100ohm Resistor
+5v > 150ohm Resistor
100ohm + 150ohm Resistors > 6.3v 33uF = Video out
Mirsku style (PAL AV mod! And internal "stereo" mod):

NINTENDO style:
Video + GND > 2SA937 PNP Transistor
+5V > 300ohm or 330ohm Resistor
PNP Transistor + 300ohm or 330ohm Resistor > 6,3v 220uF or 10v 100uF Capacitor > "ferrite core" > 75ohm, 110ohm or 120ohm Resistor
GND > 560pF Capacitor + 75ohm, 110ohm or 120ohm Resistor = Video out
This one originally has only 16v 10uF and its too little.
Jailbars mostly seem to be cause of bad power, long leads, bad insulation and external distraction, like RF unit etc. I think im gonna do it the Nintendo way cause it has been used to remove the jailbars. Seems like many people also underrate the value of good insulation, ferrite core and ground foil.
I found some "MULTICOMP - MCAB 035090-33 - FERRITE CORE, CYLINDRICAL, 105ohm".
Maby i could use it in the end with 105ohm resistor?
Im gonna use external ferrite core too, it could reduse the jailbars also.
For audio i will use only mono output. And split the sound with cable.
