  • Boot your carputer by remote?

    Hi.

    I've been looking for a thing like a remote that i could use to turn on my laptop, it can be asleep, i heard that could be a problem too...

    If you have any ideas just tell me please, oh btw, I can't mess around much with the circuits but I can spend up to $200.

    I hope you can help me

      If you have an alarm in your ride that has aux outputs, you can use the keyfob to trigger a relay to initiate startup of the PC.
      Have you looked in the FAQ yet?
      How about the Wiki?

        This is what I do. On top of that I have my Fusion Brain sense that that line is hot and it will run a script to make sure my wifi is enabled so I can remote into it or transfer files from my desktop.

          How would you go about doing that?

          Would you wire into the power button on the actual motherboard?

          The only reason I ask is because this sounds like a great idea, but I know the M2-ATX will not turn on unless the IGN wire is hot. So my mind says you'd have to make a circuit that emulates itself as the IGN. But that sounds alot more complicated then it should be.

          I painted the cilpboard mount and it looks good.
          Shutdown/Startup is working excellent!

            we87 - A relay can and will do just that.
            It acts as a switch of a constant 12v line.

              Well, You'd have to build a timer circuit with some caps that would keep the relay open for however long. Because an alarm AUX output just "pulses" and doesnt stay "latched" at all.... At least not on mine.

                That all depends on you alarm. I have a viper system and i can set any aux to be momentary, stay on as long as the button is held, or latched (stays on till button is pressed again), or latched with IGN rest (stays on till button is pressed again or if the ignition is turned on then off).

                  that's an awesome idea, so you have it set so that the aux is your power supply to the pc?

                    Hey Bratnetwork,

                    I have a viper alarm as well, mine is the 5901. Do you know if this alarm will give me the same feature to latched until i press the aux again? And if so, will I still needed the relay to make this work?

                    Thanks

                      I'm at work now so I don't have time to look into your system, but I did a quick google search on your alarm and seeing the style that it is, I am pretty sure that it has the features to do this. Just look in your owners manual and see if it has instructions for aux output. If you have the install manual that would be better because that would tell you about the pulse/latch/etc. but if you had it installed somewhere else they often don't give you the install manual so you have to come back to them for any programming changes.

                      Yes you still need yo use a relay. There are 2 reasons. First reason is that the aux output on the alarm is a ground circuit not a power (or positive) circuit - all they do is open the aux wire to ground. So you need to hook a constant positive wire to the + end of the coil on the relay and then the relay is triggered by the alarm grounding the - side of the coil. The other reason you need a relay is that the aux lines on the alarm are only rated for 200mA. They can't handle the load of much especially a CarPC and are only designed to trigger relays or very low powered features.

                        Also I feel that I must mention one precaution... If you are also using the ignition switch (r accessory position) in your car to trigger you PC, with this mod you will need a second relay or diode to prevent power from flowing from you remote turn-on back into the ignition system of the car, thus turning the power on to the whole car. If you are using a separate manual switch to turn you PC on/off then you can disregard this.
