Why not go all out?
This is a pretty good idea. I have been thinking about something like this for some time now. Except that I not only want to play cool mp3 music, but have the computer in the car run a heads up display, auto-pilot type navigation system ran on a gps, a security system, etc. This is definitely something to look into. :evil:

You might as well buy a laptop instead of putting a desktop in your car.

I am unfamiliar with what a switching regulator is.
There's two basic kinds of voltage regulators.
The linear regulator, which basically acts like a resistance to ensure that the voltage output is kept the same. Linear regulators tend to get hot, as they're effectively burning off the excess power. They're also not very efficent. They need a higher voltage input than the voltage output.

The switching regulator, which switches the input voltage on and off rapidly to keep the voltage output the same. Typically the input voltage goes through an inductor of some kind. They're vastly more efficent, they stay cooler, and they can operate with a lower voltage input than the voltage output. As they're so much more efficent, they can deliver far higher levels of power. They're also known as Switch Mode.

Aidan, how fast would you figure an SBC would need to be to play MP3's well? I know P-100 laptops suck at it.
No idea off the top of my head. I know you can pick up SBCs that'll take a PIII or Celeron, but then you've got all the extra heat. Some SBCs come with an onboard NS Geode processor at 200-300Mhz

What you going to do for a keyboard???
You could buy one of those really small ones or I think you can now buy rollup keyboards, one of those would be cool

Azriel 26th May, 2002 06:22 PM

Why would you ever need a keybard?

Azriel 26th May, 2002 06:25 PM

Here's a simplified AT PSU if you want to go AT.

What if you wanted to search for songs on your hdd (ie if you have 2000 different songs) you'd need a keyboard to type in the name of the song you want.

Azriel 26th May, 2002 06:51 PM

scroll. They are in alphabetical order.

sod that

just type in the first few letters of the song and its there
definitely going to have akeyboard on mine

If you go AT, you can get POS keyblards pretty cheap. You could program EVERY button.

mrpcman 28th May, 2002 12:26 AM

if your that desperate for a keyboard use an onscrean keyboard.

Yup, it's possible.. painfully easy, even. :D

I had to do it first.

I already plan to replace the 10" CRT with a touchscreen LCD. I still need to swap that machine out for an AT machine, and wire a relay to the inverter's power switch, so the whole thing fires up automaticaly when I turn the ignition on, but it works fine for now. I'm also going to be using a SCSI card, and a SCSI slot load Pioneer CD drive mounted under the radio in the other DIN position where the cupholder, and change drawers are now. The PC is staying in the trunk, as is the inverter.

I ran this machine for over an hour today with the engine off, and it didn't cause any problems. The car started right up.

:D :D :D

The monitor is already up for auction at ebay.

Edit: Daniel says NO URL, so I had to cut it out.

I really want to go LCD with this, and for the time being, I can survive with my 12" greyscale instead.

Hmmm... Sounds like a great idea. I'll have to pass my test and get a car first before I even think about builind one myself
