I actually used a box cutter to scratch the traces on my board (and it worked ). Just scratch one and then offset where you scratch the other so that they don't short on each other. Other than that, the 6 layers are easier because they don't require you to scratch traces (since they have a via for the bluetooth right by the GPU).Any tips or suggestions or techniques when relocating the Bluetooth module? Using my exacto knife isn't as accurate as I'd like.
You're supposed toCapacitors for regulator output? No I did not.
Yeah, that is the purpose. You may not see a difference, because you don't have the tools to see the difference. When the wii turns on it pulls a bunch of current, and if that current draw causes the voltage to drop too fast it will most certainly not work right.I talked to Aurelio about this and the purpose is to reduce voltage ripple correct? So I just soldered one on to a regulator but didn't seem find much of a difference.
You do know that the capacitor on the output is in the documentation for the regulator as REQUIRED right? If you pull anywhere close to the max output current it will most certainly drop to less than a volt.are wiis that picky?

Thanks for correcting my misinformed stupidity. I'll solder on the caps for the output and see if that helps for the previous 6 layer wiis.Yeah, that is the purpose.

No one that I know of has been designing that sort of circuit. It isn't too difficult, though using that configuration requires a transformer with custom windings, generally. There're other chips that'd work a bit better, tbh. I was going to design a circuit for 5, 3v3, and 1v2 at work before long for a product we have, I can tell y'all how it works, and if it works well I may lay out a PCB for it.This might be a dumb question, but has anyone made, or is anyone currently working on making a custom circuit board with one of these chips http://www.digikey.com/en/articles/...a-single-synchronous-buck-converter-is-simple with the appropriate external components to output at exactly what the Wii needs? In theory this could be a smaller, nicer, more efficient, and easier. And if designed in such a way, it could sit atop the Wii's motherboard soldered directly to it, minimizing any actual wires.
In general output capacitors are used to reduce output ripple. It can be a serious issue in voltage regulators, and if there's no capacitors it can cause many issues on digital and analog circuitry by the noise that will be introduced by the fact the regulator is a switch-mode reg.I talked to Aurelio about this and the purpose is to reduce voltage ripple correct?

Oya. I forgot to mention about the fact caps are also used to help make a power supply a bit more stiff. It's pretty common to have a bulk capacitance over anything with a high startup current. Similarly a lot of devices that require a sudden large current often integrate some sort of capacitive soft-start circuitry to ...soften the startup current.No problem
For future reference, high amp draw applications need output caps, low amp ones don't.
GC Video is hands down THE BEST video output for gamecube and wii. It grabs raw video data from the GPU, and processes and outputs a signal superior to the onboard video encoder. It can be used on the wii, but nobody sells a "ready to install" HDMI GC Video board with software that is compatible with Wii yet.1) HDMI on the WII, I noticed that there is a chip for the gamecube called gc video. I noticed another thread on this forum where this same chip was wired up to a N64. I was wondering if there has been documentation for usage of that on the wii yet. I saw a video claiming to implement it here (). If there is not, what is the best solution to achieving HDMI output?
They accept a Component Video (Y/Pb/Pr) signal and convert it to HDMI. You get some quality loss and latency, like any conversion, but its better than composite. If your screen accepts Component Video, you will get a better picture using that instead of a Wii2HDMI. GC video is MUCH better than Wii2HDMI. From what I have heard, the SEWELL Brand Wii2HDMI converters are not bad.2) Wii2HDMI adapters. I have seen a ton of different versions. I was unable to find any real information on how they work. Do they use the video signal from the composite or component ports? Either way it is an analog signal, but I still find it interesting.
This is a myth of rumors with no evidence to back it up. Nobody has ever tested or observed a difference. There are 2 video chips on the wii: AVE RVL and AVE RVL A. They appear randomly throughout all wiis. Any revision, new or old could have either chip. The AVE RVL is a custom chip made by nintendo, so you wont find datasheets.3) I have seen 2 variations of the AV chip. One on a black wii and another on an older white one. Googling for the names, I didnt find any datasheets (chinese chips >.< ...). I did see this thread tho (http://www.gc-forever.com/forums/viewtopic.php?t=1086). It seems to identify some of the pins, it is an old thread and wondering if there is more information.
Nintendont is region free, neek2o most likely is but I don't know if anyone has tested it.can portablizemii play games in any region
