would this work?

Hi, I'm really new here, matter of fact this is my first post. Anyways, I've been reading up and down these forums and I know most dvd players will not work for screens, however I have an Akai pdvd172. Here are some specs: http://www.epinions.com/specs/AKAI_7_Po ... DVD_Player. According to what I can find, it will accept composite video:

Video
TV Resolutions: 480i · 576i
Video Output System: PAL · NTSC
Video DAC: 10 bit
Connections
Inputs: Composite x 1 · Analog Audio x 1
Outputs: Composite x 1, S-Video x 1, Analog Audio x 1, Digital Audio Coaxial x 1
Front Panel: Headphone Jack

Would this work for a ps2p project with composite video? I apologize if this makes no sense. Thanks for any help you can give me.

It will work.
What's the screen size?
Battery amperage?

Thx for the reply, it's a 7" and I believe the battery states 8.4V

It's probably 7.4V. Or 9V.
What we're really interested in is how many mAh it is, which is should say on it somewhere.
That's the number that matters when you're seeing how long the battery will last.

Can you do it? Yes.

You will face some challenges though:
- You will need to include the entire chip along with the screen, which will make the portable large.
- It will be a huge power draw on the battery, in terms of both voltage and amperage.

These are drawbacks to any large screen, though, so if you are insisting on a big one, you could do worse.

It should be fine.
The board is the same size (or smaller) as the screen by default, it's from a folding DVD player.
And, it's low draw, because it's already from a portable. It probably takes 9V.

oh crap sorry, it's 2400 mAh

That's too low to be useful.
The PS2 Slim takes 8.5V, so you're going to want a 9V battery over 4000mAh. 6000mAh would be optimum.

Check Batteryspace.com for batteries, or get a Canon camera battery. I know they make a 6600mAh for... $36 IIRC.

so do you think something like this would work well?
or is that overkill and this would be better?

This would be awesome.
You would need 3.
The final dimensions would be 10cm x 5cm x 1.5cm.

You need the PCBs, which is offers.

I don't know how to wire it.
Get someone else to say this is okay.
Hailraiser?

great now I just need to learn how to hook up a ps2 with composit...

There's a general wiring diagram around here somewhere.

yeah, I found it, but now I have to find all the pinouts on my dvd player... thanks for the help so far though
