Hi, I've made a schematic of DVD adapter and DVD extractor :http://rapidshare.com/files/216898989/schematic.pdf
I want to ask :
1. Is that true that PIN 4 of the DVD power connector doesn't need to be hooked to 3.3 V ?
2. Please check my PIN 3 schematic, is that right? a 3.3V and GND selector using DPDT switch
3. How can I hook up LED as a Tray Eject Indicator
4. How can I hook up LED to DVD extractor module as power on indicator
5. How can I hook up LED as an indicator when Tx point is being connected to the DVD.
