PS1 Mods That You've Never Seen Before!

hey guys its vault art here and I just wanted to start off my sing I hope everyone here in the States had a fantastic 4th of July holiday weekend I know I certainly did and as a matter of fact I even did a little flea marketing as I typically do over the 4th and I picked up this SC pH 7501 which happens to be my favorite revision PlayStation 1 and the secret price is accurate I paid $2 for this thing Jesus Christ a latter-day saints that's a deal you just can't pass up on but at any rate I went ahead and check this thing out and it's fully operational no other than other than some yellowing obviously we're in pretty good shape here so I have a bunch of mods that I really want to do to this that I think you guys are going to enjoy and I don't talk about them because I don't want to ruin the surprise having said that sit back strap on and let's do it - this ps1 [Music] okay let's take the shield off nice and easy and oh look at this black tape this could be a modchip let's zoom in well this was certainly a surprise this is a looks to be a five wire installation here let's see that's not enameled wire that's just some 30-odd kynar might not even be con r but nonetheless here under this blank tape and if we kind of pull this back we can see that's a 12 C yet 12 C 508 a interesting this was probably done back in 1999 maybe very late 1998 this isn't a multimode three or certainly am i you mean and this chip would not provide an T mod let me look at it again here yeah yeah yeah that is there would be no anti mod protection so it's always interesting when you find a ps1 that's that's been shipped even today I just it's kind of like it's like a fun surprise at the bottom of a cracker jack box nonetheless let's take a look at some of the soldiering here you know just by looking at this you can tell that this was either some teenager in their bedroom or maybe even a college kid in a dorm room who just wanted to play some games obviously the solder is very cold here and not very well rented but let's let's continue with the disassembly here and let's investigate this a little further [Music] shields gone let's remove the chip [Music] now we've been going pretty fast here removing the shield and lifting this existing mod ship but we're going to start slowing things down because we're actually going to be getting into the mod work so the first thing that we're going to do is want to replace that antiquated mod with something a little modern and if you've seen my ps1 modding video pretty much all of those same techniques are going to apply it right here so sit back strap on and enjoy the show [Music] [Applause] [Music] [Music] [Music] [Music] [Applause] [Music] [Applause] [Music] [Music] [Music] [Music] and with that final joint Solberg we are totally finished with the mod ship installation that's just one small part of what we're doing to this ps1 today so we're going to talk about something else but we need to move to a different area of the board so let's do it now for this next modification we won't be doing so many jump cuts and speed ups because I really need to explain what we'll be doing here because this has never been explained to you or shown to you properly before what we're going to do is we are going to remove composite video and we are going to drive a proper composite sync signal out of the composite video output on the AV multi-out now we're going to be doing this in the most uninvaded I know how and this method is applicable to just about all revisions with the exception of a few but nonetheless the first thing that we need to do is we need to remove this capacitor right here which on the 7500 series is C 551 this is the AC coupling capacitor for composite video so I'm just going to get my tools out and we're going to remove this baby safely essentially and let's do it okay so we've zoomed up here on C 551 and you know in the past we've talked about you know techniques and easy methods of removing surface mount tech well you know what I'm going to do today is I'm just gonna take my soul during iron I'm just gonna heat one section of this I'm just gonna lift it up as I'm heating and then we'll just go to the other side and do the same thing on the other side rather than having to get out the hot air station and and heat everything up and get everything ready and that's pretty good right here I think we can do that a little more oops it's right in there there we go and while we're here we'll just go ahead and heat this other section up like so and that's it pad is beautifully preserved and so is the capacitor so let's talk about what we're going to be doing now we've established how we'll be outputting composite sink here to the AV connector but what we haven't determined is where exactly will we be pulling composite sink from well it turns out we have a couple of options the first option is the actual video DAC and video encoder chip which is what I'm pointing at right here now this is a custom spun up Sony ASIC that involves both the digital to analog conversion and the analog video formatting coding we can pull it here or we can pull it from the Sony GPU itself which is actually quite convenient because it's pin 156 which is composite sync which is right on the edge now if you look at the schematics in the service manual you'll see that the composite sync signal outputs at a nominal 3.2 volts but as anything I always encourage you guys to check this yourself put it on a scope and and just do some really simple and fast analysis to determine exactly what these signals look like as they're coming out now I've done them and what you're seeing on the screen right now is an attenuated version of this 3 volt composite sync signal now the way we can achieve this is just by simply putting in a resistor value of anything between 330 ohms to 560 and we'll repurpose that 220 micro farad capacitor to provide isolation in addition to removing anything that's unwanted what I'm going to do is I'm going to take a surface mount resistor and I'm going to attach it to pin 156 I know some of you guys are saying that's crazy that's way too small it's not too small that's what she said ok guys I hope this is a tight enough of a shot but I'm gonna go ahead and I'm going to take I'm gonna clean the tip of my soldering iron I want to jam just a little no clean on pin 156 and we're gonna do a little tinning here just so we can get absolute fantastic adhesion just like that now I have about 560 ohm resistor that I'm going to use and that's mainly just because it's what I have on hand so let me get that prepared here apply some more no clean and here I come and I'm gonna advance my tweezers in note these are the same tweezers that Nick Muller uses on a nightly basis okay now you can shoot you should be able to see this and we want a horizontally advance this in wet the joint or finished so let's just grab the other end of this resistor with the drop of note clean let's just go ahead and tin this up because we have to make a connection with our conductor perfect now I'm going to be using a 28 on stranded conductor mainly because we're driving an analog video signal well it's technically not a video signal but it is a composite sync signal and I just want to beef up that conductor just a bit and so I want to come in here with the conductor and it's very difficult to do this because I can't see [Music] very well at all and we'll give it some Wiggles here very strong okay so with our resistor and conductor installed we need to trim and cut our conductor and attach it to our capacitor here because we'll be sort of retrofitting our capacitor back into its pad so that composite st. can drive out perfectly and beautifully to the multi alum let's do it I want to drop a little no-clean on that joint I'm gonna just take my hands and I'm gonna grab the capacitor but I can see pretty well where this needs to go so I'm just gonna gonna keep this in I'm just going to advance the cab advance the cab advanced it kept like that orient this out of the way like so perfect and just like that we have finished the complete and proper composite sync modification we're driving it out of the GPU directly we're current limiting the output and we are isolating and doing some good filtering with the composite videos 220 micro farad capacitor which then craps it on out the AV multi-out so having said that we're getting close but there's just a few more things that we need to do here well I don't suppose I can keep this from you guys any longer but here's something that's pretty damn cool and very rare to find these days this is a purple clear ps1 case and I've been after this particular color for years I collect these they're really seldomly hard to find but when I find them I've got to grab them at least the ones that I don't have so I want to off-camera remove the power supply in the mainboard I want to do a transplant where we're going to put everything into this new nifty case and you know what it looks like I need to rob the logo from the other case to put it on here but nonetheless let's get to installing this okay so I've removed the power supply from the old case and I've taken the green LED out and this is a common anode RGB LED now I went ahead and fitted this in I'm just gonna rotate this around whoops lost focus for a second we rotate this around and I'm just going to solder this in and the way that it's currently configured this should be outputting blue and the resistor that's on board the power supply is plenty to draw the current so we don't have to do anything there great let's go ahead and put these leads [Music] right and as a matter of fact you may have noticed we left one conductor available we didn't clip it and we're also using an RGB LED for god sakes why well we're going to try to do something kind of neat here it's that's pretty unique so just stay with me now I'm going to connect the other leg of that led to this pad here that I'm pre tinted this pad and this connector is the power supply for the laser assembly and this particular pad right here is the power rail that supplies voltage to the laser slab so basically what that translates to is whenever the laser sled moves position it's going to energize therefore that LED is going to mix in colors because we have two different sources that are powering that LED okay so I'm going to fit my heat shrink over my conductor before I do anything that's the most important thing to do great now I'm just going to lift this conductor up wouldn't take our wire strippers and I'm just want to cut some material off then I'm just going to come in here with some solder [Music] we're just gonna tin this wire up like so I want to come in here I want to start tuning up this LED lag and I'm gonna come and probably cut it and let's see I'm gonna do a little manual measuring here in eyeball this thing I think that's pretty good so I'm gonna come right in here I'd say then this area want a cut now I want to just introduce a touch of no clean flux and my hand man getting away with this in the way of this shot I'm sorry if it does well maybe I can do this but I'm gonna come in here and I'm just gonna advance that conductor back perfect good joint I'm just gonna bring that heat shrink right into there I want to set my hot-air rework station to 100 degrees Celsius I wonder just quickly blasts this with some warm air so that the heat shrink settles and that's it well I've got to tell you it doesn't get any sexier than this and I had a great time building this system you know doing the traditional ps1 modifications that's fun and you know that's okay to do but I really like doing the stuff that you really don't see very much obviously the C sync mod I don't think anyone's ever seen that on a youtube video at least in a proper form before and the led how about that that's got to be some pretty cool stuff to see right I mean I think it's cool but at any rate you know we're gonna have some footage here obviously of the system up and running and that's pretty much it guys I hope you enjoyed this hopefully this will inspire you to take what was you know considered a piece of crap and turn it into something really nice take care of yourselves we'll catch you later [Music]

That guy makes the best videos. His narration when soldering is hilarious.
