Hdmi Plug Aka X2hdmi

Recommended Posts

just installed a wii2hdmi internal in a 1.1.

 

had a lot of vertical lines at first...

you absolutely need to solder them behind L4A2, L4A3 and L4A4, after placing the wires behind them had a crisp and clear image.

The only problem there is the limited space for your soldering iron.

 

i have removed the shielding from the av plug to generate some space.

To be honest, I soldered mine towards the Conexant chip on the pictures a couple of post back,, Xcalibur maybe it is called in my 1.6, I don't remember the name,, maybe that was the problem with my installation :/

I thought it could have something to do with internal fields interference.

I thought it maybe had better/cleaner signal before the resistors and that the Wii2HDMI internal components took care of the more pure component signals.

they are no resistors, they are coils, it is those items that do the filtering 😃

 

I will be posting my 3d printed part on thingyverse, just made a new user there.

with the 2 parts i post over there you have a support for the pcb of the wii2hdmi and a help piece for grinding the holes.

need to wait 24 pours before i can give the link.

Never thought of what they are actually :)

I've seen some of those 3D printed Ideas, but I got the idea that it would be quicker to bend a pice of metall to a bracket and solder it to the HDMI housing and fasten it with the AV port screws, since I don't have neither a 3D printer or program to make such things :)

How are you switching Mode when having both tye AV port and Wii2HDMI adapter?

Using a DPST switch to bridge the Component output points?

the last one modified i have hard soldered the mode select wires, since i only use hdmi or component.

previous one i had placed 2 contacts on the hdmi port so when i plugged in a hdmi cable they connected.

would like to show you pictures but my box here has reached 20mb and do not know how to delete......

 

i would strongly advise you not to solder, did that with the first one i build internally, the solder will break, not immediately, but it will.

I have drawn the component in autodesk inventor. i have made it free to download on thingyverse, but just made the account so have to wait 24hr.

 

If you know anyone with a 3d printer, you can use that file to get it printed, the hdmi port will fit above the av port and can be screwed down with 2 longer screws, the back rests on the plasic aroud the cooler for the gpu.

 

where are you from?

That's an alternative, but if I still have the AV port, I would like to be able to use composit too, just to be able to try it in between to see what difference it makes with HDMI :)

 

I don't know anyone with a 3D printer, but maybe worth to save the giles for it incase I someday come across someone with a printer, I don't know how it even works, if you have to open the file and print it from a PC or if you can stick it to a USB or SD card and pop it right in the printer and go from there.

I don't know how to delete picture either, it seems I have used mu quote too :) with the pictures of my games with diagonal lines in them and on a couple of Wii2HDMI pcb's

i have 2 *.stl files (stereo lithography) you can stick them on a usb stick, you need to use a slicer program with the correct settings for your printer and maetrial (and you don't have one...)

they are nice toys to play with, quite cheap as well now.

Well, I downloaded the files from Thingy, but have no idea what so ever how they work :| but I'll keep them incase I come across someone who have a 3D printer and knows about these things :)

I made my first monstrous 128MB beast yesterday, and a built in HDMI adapter would be perfect in that console for a emu/arcade station.

Look at the pictures at thingyverse. 

The wii2hdmi pcb fits in the part that is visible there. 

The other shared part is a helping piece to make the holes for the audio out and hdmi connector on the right position, with minimal margins. 

Good luck, still need to order some chips to make a 128mb machine.

Things like these are latin for me :/ when it comes to hardware I usually know what I am doing, but these software things,, I am totally lost.

I just took some Ram's from a precious V1.1 i messed up many many years ago trying to do a Ram upgrade on, when I did not have any worthy equipment or knowledge, only a flattip 60w soldering iron, now I just used the BGA machine and they came of nice and tidy amd moved them to the 1.4.

This is how I switch from the stock and HDMI

You grab any NPN transistor and a 10k resistor

Pin 9 of the AV port to the 10k resistor he other side of the resistor to the Base of the transistor

Pin 13 of the AV port to the collector of the transistor

Ground the base of the transistor

Add a link to pin 11 and 12 on the AV port

To use it

Without the composite cable(stock video lead) connected it outputs component to the HDMI adapter(wii2hdmi).

When you plug a lead into the AV port it switches to composite/Svideo output.

Aah, that's a really good idea, like a automatic switching relay, only in transistor size :)

Components and electronic theory is not my best area either, as software and such.

I know more about hardware, soldering etc, but when it comes down to the level of components, I am mostly lost, except resistors and LED's,, so a transistor, never crossed my mind :)

It's a bit ruff but it was 1am when I did that as I had a need to be able to use composite or HDMI

The only small issue is if you have the Stock lead plugged in and try to use the HDMI the picture is black and white.

Function before form,, as long as it is internal and never seen :)

Basically it is the same as a switch, either way you have to reach to the backside, flick a switch or unplugg the AV connector.

Could mount a small DPST under the front of the xbox, but as I seldom use the AV cable since I managed to get my adapter vertical line free, an internal transistor is really interesting for me.

I‘m currently trying to resolve the same issues - regarding vertical/diagonal lines on an internal install.

It seems that @Zpidelius got around this somehow with this MS9288A chip - so I‘m curious how exactly you managed to do so...

Did you remove the 75k resistors on the Wii2HDMI board?

I removed the AV port completely and directly soldered to the socket of it...

He did not get past it from internal power. 

The problem is caused by a ripple on the power supply voltage. 

 

The easiest way to get rid of it on an external solution is to make use of an USB power supply like the one from your phone. 

Just couple the ground leads and connect the 5v pin to the red wire of an USB cable. 

 

A 500mA charger should be more than enough.

Internal I had some succes with using a feroid ring and looping the power wires through it 10 times and adding an extra ground wire next to it, but that is a hit and miss, the 1.4 is the most difficult.

Would using some capacitors for filtering resolve this? I‘ve seen other systems were exactly this was done to resolve this kind of issues....

Also, are there maybe other 5V points on the mainboard that are more stable?

it seems that next to the ETH connector there is a resistor labeled 6R2 which also has 5V

I tried using caps, different variants and values, did not get any better results.

It was my external that is better than the internal I tried on a 1.6

One thing I have noticed is that locking the xbox to only 720p makes the picture very watching friedly.

I triedplaying with

480

480/720

720

720/1080 and all

480/720/1080.

But with only 720 I now have really acceptable picture with almost no visible linings, in both XBMC and games,, regardless of what game.

I tried toroidal rings like Wouter A tried feroid,, but my results were just that the more I wrapped the ring,, the more stretchblurry my picture went, until it started to shift the colors to become purple and green x) while Wouter got better picture the more he wrapped his.

As far as I can tell there is at least 3 versions of the wii2hdmi and not all work with the Xbox correctly

Apparently this version chip is BAD

I've encountered at least 5 different ones to date, and one with a chip FS9293 or if it says FS9299, hard to see on the small chip, but that one really sucks.

It deliver perfect, almost linefree picture, but it is so dark that you can hardly tell what you are doing in games if there is much black colors or a lot of shadows, even XBMC is to dark with this version.

Found this PCB with this chip in a Wii2HDMI that has one short-side flat and one short-side rounded,, so stay away from that model.

Only way I got a standard bright picture was when I turned of 480/720 and 1080 in NTSC mode,, but then the picture quality was worse than standard Composit signal.

This Wii2HDMI is even as bad on my Nintendo Wii.

It is really hit and miss with the wii2hdmi.

I use the HDMI kit from N64 freak in my own boards and there is a huge difference in price but as the saying "You get what you pay for"

Yes, those ain't no 3$ things,, but I get good enough picture when using my external wii2hdmi in only 720 to keep me really satisfied for that price ) compared to what I have been used to since xbox was released )

Rallisport Challenge, Destroy all Humans, Blood Rayne 2 and Soul Calibur 2 and many more is line free and almost Xbox 360 B,C identical looking,, so I really enjoy playing old classics on it now.

Considering the distortions are really only related to the ripple in the 5V - is each 5V on the Mainboard equally bad?
For example I guess the 5V of the Controller board should be more or less ripple-free, right?

      Hi everyone!
      What started out as a "simple fix" for an Xbox I won at SEGE last month has turned into a full passion for getting the most our of it. To that end, I decided to up my game out of the back of the console by going the HDMI route. I invested in the Pound Technologies Xbox HDMI HD Link Cable, and I am thrilled to report that the results are great! I think you'll be pleased with it, especially if you're still connecting to an HDTV through composite.
      Here's my complete unboxing, setup, and comparison of the original Xbox composite cable and the new HDMI Pound cable. Enjoy, and please share your thoughts on it.
      Thanks!
      Blaine

      I know this group has a lot of new HDMI solutions recently, and has focused on the wii2hdmi mods. ( and I know there are more options coming in the near future)
      Here's a new option for you....I've recently finalized a completely new design (it's been in the works since christmas, but I'm pleased to announce that it is now completely functional) -supports component to HDMI conversion at all supported xbox video resolutions -Wolfson Audio IC to convert S/PDIF signal for the HDMI transmitter -Individually shielded video signals -Internal install will be an option   There are two basic ways to take advantage of the digital audio 1)Direct decoding when passed through an HDMI receiver 2)Optical pass through from your TV to you receiver 3) it can also pass the stereo audio to play directly on your TV   Sales are probably about a month out still, as I will be sending units out to a few trusted testers and get testing done with some of those problematic xbox systems that are around.
