  • Starting the computer as you approach the car

    Many folks discuss the amount of time it takes their carputer to POST, and ways to get from power on to music playing more quickly. An idea I've had is to power the computer before you actually get in - or even to - the car.

    My car has a keyless entry system, so when I'm about twenty feet from it, I can unlock the doors with a keyfob remote. I'd like to intercept that "keyfob unlock" signal and use it to start the computer.

    I figure the alarm brain probably controls the keyless entry as well, but haven't yet determined where it is located in the car.

    Has anyone done this before? Any suggestions or ideas?

    have relay switch the remote signal on.

    power relay switch remote-in

    so, if the switch is on, the pc will boot.

      I'm planning on using the power features in Win2k and the VIA MOBO's bios to put the computer in hibernate mode when power is lost. So then when I start the car and by the time I get my seatbelt on the computer will be on and ready to go.

      Don't know if this helps with your question?...

        depending on the alarm, it may have a wire for an aux button, or - out on disarm or some other feature that you may be able to use for what you're trying to do.

          Win2K?

          I really cant believe people use Win2k in car PCs!
          Do you realise that probably 90% of the bootup time for Win2k is stuff that you dont need in your car?

          I have a Linux machine (P100Mhz, 32mb) which boots in what feels like 4 seconds! Ive removed everything unneccessary - It has no network, floppy, cdrom, parport etc support.

          Its not yet in my car but Id estimate that it boots quicker than it takes to get myself sat down and belted with the engine started.

          Far more suitable for a car PC.

            I like Win2k... It's what your comfortable with and is why I'm using Win2k. I've disabled all non-essential services and drivers and start only the things that I need. From hibernate mode to functioning takes less than 30 seconds.

            So by the time I start the car and buckle up my gps has already got a lock on 12 satellites and is ready to track. I'm cool with that.

              I think what you will find is that not many people know linux well enough to have everything they want on it. And Personaly I'm not really excited about taking the time to learn everything just so I can't have Copilot 2002 in my car.

                The alarm and keyless entry system are OEM, so it won't be as easy as interfacing with a Cobra's AUX output. As I said, I haven't even figured out where it's physically located yet!

                As far as the OS is concerned, Linux is clearly superior with respect to stability and speed. It lacks much of the functionality of Windows, however, particularly from the standpoint of the developer. Using Windows, there are vast quantities of free components and code snippets, speech input and output APIs, and ActiveX interfaces to all sorts of stuff. Perhaps one day I will be knowledgable enough about Linux and ambitous enough to undertake the herculean programming task... for now, though, I'm well-matched with Windows 98 Lite.

                  you can tap into the door lock (the pulse is usually only 1-2 sec)but you will want to be able to deactivate this with a switch or relay that is open when the car is running so you don't trip the computer if you hit the unlock button in the car,
                  also the way you connect this depends on how the locks are triggered
                  trigger -lock +unlock
                  trigger +lock -unlock
                  reverse polarity for lock or unlock
                  If you come out talking sh1t don't try to turn around and wipe you azz.

                    Ok, here's what I can offer you..

                    From this web site click here
                    you can read on how he removed the progressive feature to where both doors open up on one push of the button. This leaves the push push feature open for what ever you may need it for. The link is for a GM 98 Z28.//

                      I know ive seen wireless (rf) computer starters floating around (try outpost), but if you didnt mind another fob, this would be a very simple way of doing it. I don't know about the range either, but its a simple fix.

                        I've seen that and it sounds exactly like what he wants.

                        I once had a link..... it's gone now apparently. I'll keep looking.

                          Get 2 cell phones. Hook one up to your comp and call it with the other There are tons of remote start/shutdown modem controllers that network admins use when servers go down in the middle of the night...

                          That was my idea 2 years ago...hasnt progressed in any way. But hey, you can get those crappy 1cent phones and buy phone cards for them at bestbuy.

                          You would need something like http://www.servertech.com/products/desktop.htm to recieve a phone call and turn it on. Do a search for "remote power management" on google to get some other products. You may be able to dig something up that works with IR.

                              This is getting mildly off-topic but I thought Id reply anyhow.

                              Yeah, if you try and use Linux as a desktop machine it (for most people) lacks way too much software. Simple things like decent IMs, file sharing apps and graphics programs just arent mature enough yet.

                              However, I cant understand what youre saying about developers! Probably 60% of Linux users are Linux programmers, its a programmers heaven! When I first installed Linux and started developing on it I almost orgasmed (my previous platform was Windows with MSVS and Delphi). I really cant understand how you have arrived at this conclusion.
