I was wondering what the ground and power ground stuff does and what it has to do with wiring a sega to a PSone screen. Could someone tell me?

1) shorten your avatar

2) ground means negative

actually, ground is technically just the 0V reference point in a circuit. but in terms of batteries and what not, it's the negative lead from the batteries.

when building a portable power must go to the system and the screen, and audio/video must be connected between the two (along with ground).

connect a 7.5V-9V source to the psone screen, and a 6V (or higher?) source to the radica.

w8, so just to get this strait... the battery stuff goes to the Power Ground (correct if wrong) and that goes to the screen. And if so, what does the normal ground stuff do (audio, video stuff???)? meow

Battery Positive to Gen board positive.
Battery Negative to Gen board Negative.

(using the radica screen)
Video on Gen board to Input on screen.
Ground from video wire to ground on SCREEN board
Audio on Gen board to sound input on screen board
Ground from audio wire to ground on Screen board

That's pretty much how it all goes. I've done this many times so I am POSITIVE that's how to connect it. Only reason why i never finished is because I screwed up the board trying to connect a cart slot. =(

w8, can someone show me a pic of the negative and positive parts of the gen? (sorry I'm so dumb with this

)

Oh yah and speaking of G-Force's site, what size DC plug fits the PSone screen?
The site/G-Force said

5) DC plug that will fit in the power jack of the PSone screen.

Can someone tell me if you can do that stuff with a mobo. Because I fortunatley have a v. 2 and 3 but want to make something like G-Force's Ondago but a v. 3.

It should be almost the same thing really, you just need to locate where the video and audio pins are in the v3 mobo. I haven't worked with the genesis mobo (only radica) so you would need to research this on your own.

Oh yah and speaking of G-Force's site, what size DC plug fits the PSone screen?

Simple, just modify the original plug that came with the screen! If you don't have it, search ebay or see if anyone has a spare that they can sell you.
