First off, this should not be posted int he FAQ Emporium. Pay attention to the forum you're in before you post.
[QUOTE=brentm]Here is my plan: I know that people on this site do not like to just tell someone how to make their carputers. But here is what I plan on doing.
1. Hardwire a 12volt adapter into my car using the remote turn on lead from my deck. Move the power and reset buttons to somewhere in my dash. Unless I can get the computer to automatically turn on with the deck somehow.[/qote]
Define '12 volt adapter'. Do you mean an inverter? Perhaps a 12v power adapter for a laptop? Give us details, man.
You can use a DC-DC power supply (no inverter necessary) for a desktop-style setup that will turn on with the ignition, just like your headunit.
Good start...2. Plug in the power supply and install the computer components.
OK. You're not going to see much information, but OK.3. For the screen I will be using an LCD mini display screen.( http://cgi.ebay.com/HD44780-20X4-Cha...QQcmdZViewItem)
I suggest using one of the units from CrystalFontz of Matrix Orbital, as they come with software you can use to display information from various applications and have triggers set to display different information under various circumstances and such. They also have serial and USB models, not that a parallel unit is a bad thing...
That all sounds peachy...4. I will be running windows xp on the carputer with winamp automatically running on computer startup. I will also install correct drivers/software for the LCD screen to work.
5. I will connect the speakers, via an auxillary input adapter (Sony deck does not have AUX inputs, but an adapter can be bought to change the cd changer plug to aux inputs) Split from the soundcard into RCA’s and then run the RCA’s into the new aux input on the deck.
6. I will control winamp through a USB keypad/numberpad that I have, I will just set hotkeys.
7. I may do an external USB hard drive, or an internal one, I plan on getting a rather large one so I will not have to refill it often.
Startup/Shutdown controller. Some DC-DC power supplies have them built in.Here are my questions/concerns:
How do I get the carputer to turn on automatically with the deck, and if the carputer needs restarting, do I just turn the deck off and then on?
Again, no details about the computer. Most computers do not have a startup controller for a car, nor a regulator for a 12v DC power source. If you've purchased a car-specific unit from ebay or a forum member or some online vendor that sells systems setup specifically for a vehicle, then it may. Again, we have no way of knowing, as you've given us absolutely no details on the setup.This should all be coming from a computer that is about a year old, so the power supply has the built in regulator and startup controller in it.
Again, pay attention to the forum you're in before you post. The FAQ Emporium isn't the place for your questions, but a repository for answers to those questions. For n00bs, it's a place to read, not post.
