Screen FAQ / useful info

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

I know this sounds stupid, but how does one get power down to 7.4v, if an atari uses 9v? Would you need some type of resistor, or what?

How can I LED mod my screen? (it's a psone of course)
I've passed Vertex^2 Expert :)

Is that a serious question? You posted a question in the sticky where the answer is. On the first page. In the first post.

Wow.

That's all I have to say.

I bought this screen for a different project and it's a really nice screen. Costs a bit at @ $70 shipped, but I like it.

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... %3AIT&rd=1

It has the same resolution as a PSone screen and it strips well.

Sorry if this is well known.

*EDIT*

I tested the voltage, I have a multivoltage power supply that does 12v, 9v, 7.5v,and 6v. It works fine all the way down to 7.5v. At 6v it turns off and on. So I'm guessing that it should go as low as 7v just fine.

that looks like a pretty nice screen, does it run on anything lower than 9volts though?

Well I can test it tomorrow and let you know. I'm at work on the road and won't be home until then.

Sorry for the delay.... Here's the results.

I tested the voltage, I have a multivoltage power supply that does 12v, 9v, 7.5v,and 6v. It works fine all the way down to 7.5v. At 6v it turns off and on. So I'm guessing that it should go as low as 7v just fine.

Looks like it would be an awesome screen for portables :)

Sounds good, what's the power consumption?

I couldn't tell you now... I was using the screen for a projector and now I've wrecked it....

I'll buy a new one but it takes 2 weeks to get it from overseas.

Mine's on its way! Super compact portable, arise!

Just to make sure no one misses this or asks this question again (hey, I searched the sticky and didn't see this info jumping out at me):

PSOne screen power consumption: 750 mA with original backlight, around 350 mA when modded with 3 LEDs

If you add more LEDs (some people here have even used up to six), you increase power consumption. Keep that in mind.

Any way we could put that bold sentence at the end of the very first post?

Wow that screen looks nice, Maybe the prices will go down and it will be our new hip gear.

If you're looking for a slightly larger screen for maybe an Xbox360/Wii laptop then look here:

http://www.lumenlab.com/forums/index.ph ... opic=16528

It's a Wxga (1280x768) 10.6" Lcd with Controller. It does 480p, 720p, and 1080i. It has VGA and Component inputs plus a lot more. It costs $260 shipped.

quick question:

I have an intec screen pad (a lot like hipgear screen)
and it did not come with an adaptor. I either buy an adaptor (which I mentioned in the trading post), or I power it manually. I want to power it by putting voltage right into the regulator or the power cord (power cord preffered) just how much voltage do I need to pump into it?
I couldn't find this info in the early posts.
