This Video shows you how you can easily use your old useless Video Cable to build a USB to 3.5mm Audio jack converter.
For this converter i used the video cable which allows you to watch your videos or pictures on the pc. There are 3 cables. The yellow one is for the video signal and isnt needes for this project. The other two (red and white) are for the audio.
White - Left
Red - Right
Both cables present 2 conductors. A negative one and a positive one. The audio jack has 3 contacts:
- Positive Left
- Positive Right
Solder both negative contacts (the conductor which is on the outside) to the negatice contakt of the jack. Then solder the other 2 positive whires to the left and the rigt contact of the jack.
Sorry for my bad english, iam from germany. If you have any questions please feel free to ask me :)
