Thats great =] I hope those go as well as this one.

@edmaul69 hi im trying to do a psone screen hookup like this via the av is it possible you can post the pinout or a pic of a close up of the sodering for pinouts? Thanks!
-
@junkmang612 so if you look at the pic of the cut out av port the first pin is white audio. the second pin is red audio, then yellow video. the next pin is ground but i ended up having to solder ground to one of the 4 support pins outside of the pin header
-
Also remember the lcd uses a different voltage than the pi. You could use a voltage regulator to drop the power from 7.5 volts to 5v but you need to use a heatsink on it to keep it cool.
-
@edmaul69 thanks for the info. I ordered a ubec voltage regulator from adafruit. To drop the 7.5 to 5v.
-
@junkmang612 what is the amps output on the psone power supply?
Edit: appears to be 2 amps. That may or may not be enough for a pi 3. The lcd probably could run off of 5v. Are you attaching a hard drive or anything else to the pi?
-
@edmaul69 im using the psone lcd power output to connect to the power converter. The power from the psone lcd is 7.5v at 3 amps and the ubec will convert to 5v at 3 amps. Hopefully that should be enough for the pi and and a hard drive.
-
@junkmang612 yeah you should be just fine at 3 amps. As long as you use a usb 3.0 hard drive. The pi cant power a usb 2.0 hard drive on its own.
-
@edmaul69 do you happen to know what i need to do to default display to composite psone screen on the pi 3 running retropie?
-
@junkmang612 just make sure in /boot/config.txt that there is a hashtag in front of
#hdmi_force_hotplug=1 -
@edmaul69 said in My Sony Pistation 1 and Super Mario Bros. Zero Cart:
over the years i have done hundreds of custom console and arcade mods. i will be posting some of my raspberry pi mods here. these are the first two on my list. first is my playstation one. i put the hard drive in the disc drive since i had no other space. since i dont have money for another usb 3.0 drive i had to use a usb hub for the 500gb hard drive i had lying around. (the pi 3 can power a usb 3.0 hard drive where the usb is soldered on the drives motherboard.
the red and yellow in my cable are actually backwards if someone decides to do this
Finally!! A playstation that can deal with switching between a/v and hdmi without having to go into a secret settings reset to switch back and forth. :D
Sorry for necromancing...
Im building a PsxPi too, So far I got it all down, except the Multi AV port. I got a working HDMI port, and when I try to solder the Multi AV port, Im running into some problems.
My RCA Cable only has 3 wires. Red, Yellow and White. So far So good. I soldered them to the Pinout on the PS1 MultiAV Out. I Can get picture to the CRT, and distorted Sound (BIG TIME), as well as a rather slow emulation (no idea why). Mind you that I only soldered 3 of the wires. In your photos, you soldered a 4th wire. What is that wire? From the Pinout of the PS1 Multi AV out, it should be video ground, right? Are you soldering the outer wire of the video cable to pin 8, as said on the Ps1 Pinout?
Either way, could you explain me what Im doing wrong? Any idea why my Pi is running so slow through RCA (even in the PS1 native resolution)? As soon as I switch back to HDMI, the pi goes back to normal...
Kinda would love some help -
@Joanesthefool 4th wire is ground. Without it you have all your issues
-
@edmaul69 Thank you, but I still have doubts.. Which is the ground you are using? My cable has 1 ground for L-Audio 1 Ground for R-Audio and 1 Ground for Video. I soldered the Video Ground to pin 8 but my problem persists... Any help?
-
@Joanesthefool all the grounds can get grounded to the big posts. If you are using a coax adapter you have to add a 5v wire. Can i see a pic of your plug and the bottom of the board where the wires are soldered?
-
@Joanesthefool what cable are you using? If it is an old cable then the red and yellow could be backwards or the grounds are on the wrong pin.
-
hello edmaul69
So here is my attempt at soldering...
Im sorry about the soldering... Self Taught, this is my 3rd or 4th atempt at soldering, and my soldering iron is not so good...
And this is the problem im getting:
-
@Joanesthefool i know your problem. You need to solder the red video ground to a big ground post like you did the other two grounds. Use the ones on the other side. Looking at an actual sony cables pins, the video ground pin isnt even there which means it is using the sheilding ground.
-
Thank you! =) Video is perfect now, but sound still has tearing and slow/distorted...
Any config I need to activate? -
@Joanesthefool what country do you live in? In /boot/config.txt what number is sdtv_mode= set to?
