PlayStation and PlayStation2 AV adapter
The
actual device seen in real life really looks a lot cooler than what you can see in
the pics. Its more impressive too becuase you can see the careful soldering and patience
that went into it.
My first mod was the adapter for my PlayStation and
PlayStation2 consoles. Mainly used on the big grey PlayStation, but made for the
PS2 in this contest.
I started off by ripping out the PSone screen's AV Out board.
In case you don't know what it is, its a board that's inside the PSone screen by
Sony that connects to the Psone, but also allows another AV Cable to go to the TV
too. This board contains all kinds of stuff. It has a headphone plug, and an AV "in"
plug. The plugs do not work directly with the board. The plugs need to go through
the PSone screen via many wires first before they go back out to the headphones or
in from AV "in".
Anyway. I re-directed
the headphone and AV "in" plugs directly to the board. Now, you can just
pop in headphones or an AV device and use it without going through anything else,
like the PSone screen.
I also added a switch to turn
just headphones on or normal TV audio on. Why? Becuase I found out that when headphones
are plugged in, it cuts off current to the TV for uudio. I figured a switch would
be a better approach. But there's a problem with the board. I accidently bridged
the left and right audio points. Now, even if you plug both left and right in, it
still only plays in mono. I may buy a cheap broken Psone screen just for the board
and re-do it.
But wait! Could I have added an LED
that lights up when in headphones mode? Yes! And thats what I did. The LED's ground
goes directly to the board. When you plug the board into the PlayStation, the grounds
connect from the board to the PlayStation's board and grounds the LED. So now I don't
have to have 2 wires running into the PlayStation. But, the power for the LED may
have to run via one wire into the PlayStation. Or does it? The pic shows the LED
power wire just hooked up to it's power source for now to show it works.
I
thought about modding one of the pins inside the PlayStation to send the 5v required
for the LED through the board, then to the LED, BUT the 5v current would also go
to the TV. No, wait. It wouldn't. The Sony AV Cable I have only has pins for left
and right audio, and a video pin. As long as I use a pin that doesn't use one of
those, I'm safe.
But wait again, something weird happened. I was just messing
around touching the LED pos. (+) wire on the adapter board with the PlayStation on,
and it plugged in when the LED came on. I went, "What the f...?" So I started
touching the area of pins that lit it up, and sure enough, there's already a power
current going through the AV Out on the PlayStation that can power the LED! No special
pin just wired up for that. Yes! All I had to do was solder the pos. connection of
LED to that pin according to the set-up of the switch too, easy.
This
board is completely portable, and ready for use on any PlayStation or PlayStation2
console. Complete with headphone mode LED and everything! So, here's the summary
of this mod...
1. Portable board that contains many usable items for PlayStation(2)
2.
Headphones -no amp yet
3. AV "in" using 1/8 in. male conector
4.
Headphones / TV audio mode switch to change between each mode
5. System powered
LED that lights up when in headphones only mode -no external wire to connect to the
PlayStaion(2) for power. Plug-and-play you could say...
6. Completely portable,
and ready-for-use on any PlayStation or PlayStation2 console.
Drawrbacks...
1.
The board is completely in mono due to some bad soldering.
2. The board is not
covered up with a case, but still looks cool, and high-tech, sort-of
3. THE BOARDS
IN MONO!!! EVERYTHING!!! I can't stress this one enough. I plan to do this again
if I ever get my hands on a broken PSone screen, this time, completely stereo for
headphones, AV "in", and out to TV. Complete with an amp too.
