Thread: Wild Things PSone LCD to PC

Kraft, thank you for the links, the software is especially useful for another LCD project I am working on where the graphics card in question does not willingly respond to custom resolutions.

I will have a proper look at the circuit diagram soon however I cracked it, albeit a black and white image just like M Pro did on his first try but at least I am getting a stable image of my test machines Windows 98 desktop. Some obvious tweaking is required and like M Pro I need to do more testing and limiting with resistors until I get the best image.

Thanks to Oracle, I had the motivation to go ahead and prove it could work. Okay guys I will keep you posted as to how I am progressing but the key to getting the screen up was good grounding. I managed to workout the circuit board and which wires went where and did what and realized that there is no ground point, its being provided by the input from the PSOne console so I just rigged up a strip board, connected all of the RGB and V/H Sync grounds to this board and then attached the board the ground coming from the DC power mount (the main RGB controller board is using the same point for grounding).

As I mentioned in my original post, the whole thing is such a cheap job that the input/output board is literally falling apart so I am having to fabricate new connections as I go along.

Fingers crossed...

Ok i used to have the same issues with mine, had b&w picture when i first tried with the tv out of the graphics card and that was normal, the psone was expecting PAL RGB and my graphics card was sending SECAM which is a kind of encoding and timings like NTSC or even PAL. The way i solved this was to leave the idea of using tv out and replace it by the original vga out. Then everithing worked fine. So you must be able to do the same.
About the links i gave you, the suggested schematics are the complex and heavy ones, there's another one which runs only with few resistors and 2 transistors. This one is the good one. I seeked quickly yesterday but had not enough time to find it. I'm sure if you allow some time yourself to seek in google you will find out too this light schematic.

Hey Godz...

Hope my post wasn't taken in the wrong way. I wasn't trying to put you down or anything. Was just that for me, I found me time and frustration to make the reality of using an unproven lcd (Interack in my case) just not worth it.

I hope you achieve success and are happy with the results. One you get it working, let's see some pics!

Best Regards

Mike

Hi,

I've managed to link up the WildThings LCD to the composite video out of my Digital Still camera. (Normaly used to display pic on TV).

Heres the connections:


And here is the menu on the camera working:



Now I just have to get it to work from the TV Out on my Geforce4. But i've lost the cable :/ .... stay tuned.

Godzi11a you still working on it?? some pic's of it working would be nice.

I think I worked it out, after having a good read through the gamesx.com site I found the pinout details that I needed to workout what wires where.

For anyone who has a Wild Things PSone monitor, please follow this guide:

1. goto gamesx.com Playstation A/V Pinouts

follow the two pics and workout what the pin arrangements are, on a Wild Things board its easier to work out the pin arrangements if you look at the image of the AV MULTI OUT connector (second image on right) and then get your Wild Things power board and look at the AV MULTI OUT connector.

You will see that the plastic connector is surface mounted and on the back has legs going through the board (soldered on the other side) - you will notice that the pin arrangement is inverted compared to the guide provided by Starfox, thats because the Sony version is not mounted in the same fashion as the Wild Things connector.

If you look at the guide on gamesx.com and then follow each leg to its soldered point you will workout which pin is what.

2. Below is a diagram I put together of the pin arrangement for the Wild Things version of the PSOne monitor:


Sorry for the crap quality but I have marked the pin arrangement for clarity, anyone with one of these monitors should be able to workout what I am on about.


Here is a shot of the AV MULTI OUT connector, I have marked the arrangement of the pins for clarity.

3. Follow M Pro's guide to wire up the the RGB VGA cable to the board.

That should be it, with any luck you should get an image, my initial image was surprisingly good if a little hazey but I have been tweaking the image via Power Strip and I found out the pots on the actual LCD front are used to control the image so a bit of tweaking here resulted in a slightly better image. I am not going to post any images just yet as I first want to workout what the correct settings are for Power Strip using an ATi Radeon, an ATi Rage Pro 128+TV OUT and a Matrox - when done (in a few days) I will post all the details so any Wild Things owners should have all the info they need to get going.

The only thing I need to do now is wire in the correct resistors to improve the RGB signal (I used a res that was near enough to what M Pro suggested).

Cheers and good luck.

I'm also trying to get my 5" Trustmaster PSOne LCD work with my PC. I've follow M Pro's guide to make a RGB to VGA cable. I get a picture (not that good) but the screen is flickering and I can't get it to stop flickering with PowerStrip.

I've read this -
NEW! [Jan 12/99]: You must add a 220uf capacitor in each of the RGB lines to get an acceptable picture. If you don't, the picture will be too dark and you won't like it!
but I don't understand how the capacitors should be connected.... need some help here.

Godzi, any progress?

I've got a steady picture (no flickering), but the picture are to much green in the colour, what could be wrong? Also I would like to know how I should connect the 220uf capacitors on the RGB lines (+ and -).

Sorry if I'm novice but I'm learning.....

Cheers
