    lol... that's funny.

    just tell her it's the wrong switch. or just use it for something else. (i.e. throw some mood lights on the ceiling )

    the switch would actually work fine it's made for automobile installation, i'm considering using it for the screen and the Cigarette Lighters instead though, i hate the fact that cigarette lights are a constant drain on power.

    It depends on the car though..... Mine shut off when the ignition is turned off.... The socket for the rear doesnt, and the one in the center console doesnt....

    since you USB hubs run on 5VDC, you can power them directly from the OPUS +5V rail (instead of running two 12vdc-5vdc PSUs off the OPUS +12V rail). modern systems don't pull much from the +5V rail, so chances are you have enough unused power for your hub(s).

    yes, if you power the hubs from the main relay, power to the hubs will be cut before the PC shuts down. the solution to this is to run a second relay for the hubs, with the OPUS +12V rail as the coil power. (see diagram below);

    totally random question, is it possible to use a DC DC adapter on a laptop install? or is there another way you can think to power a usb hub w/o using an inverter?

    In the past i have connected USB hubs directly to the OPUS, which resulted in melting.... It may be because of polarity error or to many amps. Thats why I went with DC-DC adapters to kill my worries. I was also worried that the 5V rail would not be able to handle two 7-port USB hubs.... I would love to eleminate the DC-DC adapters though, they take up alot of needed space. What measures can I take to ensure nothing gets fried?

    I think, someone correct me, you can use the laptops power brick without an inverter. If you want to power the hubs, use a DC-DC adapter.... the ones I have only go between 4.5 and 6 volts. I have them set to 4.5 volts with no noticable issues.

    how would i use the brick w/o an inverter, it comes out of the brick on the laptop end as DC, but has to go in as AC.

    the power brick that comes with a laptop is an AC-DC power supply. you would need an inverter to use it.

    you can buy DC-DC auto/air adapters. they look similar to the bricks that come with laptops, that may be what you were thinking of.
