    Question Shut down controller

    Can anyone tell me where to get a Shutdown controller. I haved emailed a few people about it, Jeff, MP3car.com and some other guys but no one seems to be able to help.

    I'm in the UK and desperately need a way of automatically shutting down the PC. It is such as hassle switching it of manually. I put a relay in the 12v+ line to the inverter and ran it to the acc so my battery doesn't go flat anymore when I forget to switch it off but It's not too happy with me when I start of stop the engine. The PC just powers off.
    Please somebody help!

    PS Just got a 120GB HD and using it to play my DVD's straight from the hard drive. It's great, no more discs, it's just like a changer.

    If you want something simple to keep powering the PC for a few minutes after you've cut the ignition, try my circuit:

    If you want your OS to do a proper shutdown first, look for a real shutdown controller.

    Cheers

    Mastero,
    Ok I have checked it out and it looks good.
    I've sent you an email and order for the ATX Controller.
    Thanks very much

    Keep in mind that you may have to use a different relay and add some extra trace to Mastero's shutdown controller. With more and more people using Keypower/Opus/Arise power supplies to power P4s and AMDs, it is more and more of an issue. I don't think the relay he used has contact ratings over a few amps. Plus the traces and the gauge of the wire limits the current you can put through it. Keep in mind that a 25 mil (a mill is 1/1000 of an inch) trace is only rated for about 0.7 amps. If it is really short then it is just a small resistor. But If you have a long one, the resistance really starts to make a difference. If you want to make sure it won't start a fire or anything. Measure the ammount of voltage drop from the wire at the input to the wire at the output when the computer is on.

    If it is more than a few tens of millivolts, then you have shutdown heater.

    The shutdown controllers mentioned here actually send a shutdown signal to ATX mobos (via the ATX PWR header). You can usually configure that to do standby or hibernate instead.

    My circuit simply cuts power after a delay, that's all. I just use two of them in series to do a proper shutdown. The first circuit has a long (~15 min) delay, once it fires, Linux begins to shut down, while the second circuit keeps it powered for another 15 seconds. (I interfaced the shutdown signal via the joystick port.)

    Last week I just finished building this circuit -

    http://groups.yahoo.com/group/dashpc...%20circuit.jpg

    It's by Micheal Carr that hangs out on the dashpc groups there at yahoo. You may have to subscribe to the group in order to see that file.

    Anyways, this circuit runs beautifully. It simply simulates a power button press to the motherboard whenever the circuit senses power on or power off from the 12v accessory line.

    I use an EPIA 800 MB, and WindowsXP - XP is set to go on standy whenever the power button is pressed. The result, 8 second boot time.

    Mind you, this is only beneficial if you're using a DC-DC powersupply. Powerdraw from the motherboard is around 700milliamps (eq. to powerdraw on your car radio for keeping presets stored).

    It doesn't have any type of time delay, but you could easily add one to this circuit by just doing a search - there's been posted a few seperate circuits for simply just producing a time delay.
