Screens that accept analog RGB.
15Khz or 31Khz? :lol:
I know that most consumer lcds do if you're willing to modify them and solder to small smt leads, but the psone lcd is one of the few cheap ones that comes to my mind that allows rgb without any modding.
Soldering is not problem. And ...

ah.. it didn't look like it had any controll buttons :)

Edit: yeah, looking closer I see the joystick and the top buttons :)
The controls on the face are jacked from an NGPC and the trigger buttons are NGCD pad/Genesis pad hybrids.

The unit I made is a supergun that can be used either as a ...

all lcds use RGB.
Its just really really hard to find the lines for it. Sometimes they are not even there.
This is definitely not true. Take the Neo Geo Pocket. It does not accept RGB, only digital input from the processor direct. It is possible to get a picture from the processor in RGB, but the ...

I know the PSOne screen accepts RGB. Which others? Is the Hip Gear screen composite that is converted to RGB?

In the future I plan on doing a write-up of my project on my website www.multimods.com:

Has anyone else tried the resistor short and there was no improvement in the brightness??
I tried the mod with tin foil, then solder and there was no improvement at all.
As a result, I had to use a flourescent tube.

Anyone else had this issue??
Yes, for me it didn't work either, specifically with ...

You probably roasted some of the other components on the board, not the 7805. You need to go into the board with 7.5V. Not 12V, not 5V. Use an LM317AT and build the circuit to get it to 7.5V. With proper heatsinking it will work, taking 12V down to 7.5V. It does get HOT as you're releasing 4.5W or ...

Oh that's not a problem, that's perfect.

Sparkfist wrote:Well for its size, translate it to inches and that ~4.38" thats not really bad considering the Hip Screens, GBA and even the Nomand's are 3" and under.

I believe that's 2.72" diagonal.

Seems to be non usable for most applications.

Wow, this is a cool thread.

And the LDO, it should work, unless you dont have it ground or something. But I doubt you'd over look something as like that.
Well, he said he only swapped one of the 7805's out, but there are 2 in the screen. I think that's the problem
I should see something though. I have to check again.

But ...

I see lots of talk about getting it to work off of one or the other, but it seems no one has gotten it to work yet.

I tried swapping out one of the 7805 regulators for a 5V LDO reg and ain't happnin'. I need to go back and check on this, but I'm curious if anyone else, for all the talk here, has ...

Actually, although maybe not in this thread specificly, I wrote up (or actually copy and pasted :roll:) a fairly long explanation of how they are different.
Well, I'm new to this board so I just assumed since the conversation is 5 pages long now with no one giving any details about it that there ...
