    This is a DVR-110D, but you can undoubtedly do something similar with with most drives, especially it's Pioneer relatives.

    LED's are mounted inside the drive - there are of course constraints to be met here:

    We must not foil the mechanical components of the drive, eg. the tray, and the light must go somewhere where we want it, e.g. out the front.

    In this case, the top and bottom parts of the metal casing are removed from the plastic chassis, and a rectangular section cut out from the back of the upper steel casing, above where the rear connectors are. Two holes are drilled in the black plastic chassis, and LED's inserted.

    The anodes of the LED's are connected to +5V on the main PCB via appropriate resistors.

    Now here's the tricky bit.

    One of the pins on the tray limit switch is grounded only when the tray is fully extended, so the cathodes are connected to that.

    I'd show you specifically how it's wired up, but i can't be bothered removing and disassambling the drive right now.

    Works as planned - the LEDs illuminate only when the tray has fully opened, and turn off immediately when the tray starts to close.

    Nice simple and clean, I like the idea. Especially to turn the LED's off once the tray starts to close just to make sure (not that I think it would) there is no conflict of the LED light and the laser.


    Good mod. :dremel:

    This could be useful for switching an XBOX DVD drive with a PC DVD Drive to make the extra connector.

    Basically inside an optical drive in general there will be any number of pressure switches that can detect if the drive tray is fully extended or fully retracted.

    What I believe g0th did was to fix a lead to one of the wires going to the fully extended tray detection switch and when the switch gets grounded (aka pressed) the LED's light up since their +vcc is always connected and by grounding the LED's turn on

    This is something how I figured its hooked up like:

    Its not the tactile switch for tray eject. The switch I have pictured is a switch that detects when the tray is out. There will be one somewhere in your optical (no clue where in your specific one)

    The switch will probaly just look like two thin pieces of metal. somewhere that the plastic of the drive tray will make a switch press.
