Because my TV is used mainly for watching. I need an alternative display output for my cubieboard. The easiest way is using CVBS pin, and attach it to RCA jack to connect to video input. But I don't have another display with video in, so I need to built VGA out for the cubieboard.
Component needed :
- 3 x 75 ohm low-tolerance resistors.
- 1 x 74ACT08D quad AND gate.
- 2 x bat54s SCHOTTKY diodes (I can't find it in my local store, so I change it with 4 x bat85s or any SCHOTTKY diodes).
- 1 x 100 nF low-tolerance capasitor.
- 1 x VGA DB15 connector.
