This is outstanding. I just... I have no words. Keep up the great work. <3

Indeed it is... but we've all been there :P

I don't think there's any way to save a fried mobo, if that's what you're asking. And yeah, shorting voltages will do it. Lesson learned - if you're reading voltages at that spot on the board, be super careful, because those 3.3v/7.4v/ground pins are very close together. I learned that one the...

These are a good buy, cheap, and I received it a few days later. They're super small but still easy to use. I'm considering putting this in an rpi portable.

What you need is 7.4v. Most people do this by wiring two 3.7v cells together, along with a pcb. You could use any number of 7.4v camcorder packs in parallel, but no, it is not mandatory to do it this way.

Yes, you need a pcb, you can't have 3.7v cells unprotected. It's nothing to do with 3.7v vs 7.4v; I would assume those batteries in the bottom diagram are made up of two 3.7v cells, and include a pcb. Really makes me want to make a decent n64p wiring diagram for bb. There are some okay ones and...

Nah, I've definitely had some backup screens that worked with other composite signals but didn't work with the n64, and I remember others mentioning this as well, on bh and mr. "Good ones" should be able to support any composite input. As for Gman's recommendations, he has them all...

No, that stuff is for 3.7v battery packs, you need a pcb + charger for a 14.8v battery pack. That holder holds 4 cells yes, but they are wired in parallel, which multiplies the capacity x4, not the voltage. Your cells will need to be wired in series.

Riiiiight. 4 3.7v cells is what you need. You decide if you want to get decent ones or these ones. Generally the range for 3.7v cells is around 3.2v - 4.2v, meaning if you have 4 of them in series, the voltage range will be around 12.8v to 16.8v, depending on how charged they are. You could...

Well the important part is the joystick, not the board that it's on. The only thing that board is accomplishing for you right now is supplying both pots of the joystick with 3.3v and ground. See how one side has 3 wires - 3.3v, data, and ground, and the other side just needs a data wire because...

Yeah, definitely test with a multimeter first, instead of just wiring up to the wii and hoping for the best. *If you don't own a multimeter, get one* Most of these questions you're asking are answered in this bad boy right here...

Saw what? ;)

I'm assuming you're powering everything with their original powers supplies, Wii with Wii power brick, amp with USB (or something else??), and screen with the power supply it came with? How bad is the fuzziness? Does it correlate with the audio (does it vary, depending on how loud the audio...

I'd be willing to do it / help!

Okay, here's an idea: Having a Projects Showcase more similar to how it used to be on benheck (it's not up anymore and I don't remember exactly how it was, just that it was awesome.) Basically, it was a list of all portables, and you could click one and it would have a dedicated page with a main...

Stock regulators are the voltage regulators on the motherboard inside the wii that regulate the voltage from the power cord (not the av cord, av stands for audio/video) to power various onboard components at their required stepped down voltages - 1v, 1.15v, 3.3v, etc. If you aren't planning on...

Usually what people do is instead of having a switch on av, they just have a power switch for the internal screen. This also helps save power, since you wouldn't need the internal screen on while you're hooked up to a tv (obviously) :P You CAN get away without a switch of any kind, but you'd be...

Is the reason the PTR08100 is used for 1.9v instead of just another PTH08080 because of the higher max output current? Was thinking of using 4 PTH08080 for 1v, 1.15v, 3.3v, and 5v for a wii regulator...

Integrating a sideways wiimote is a lot of extra effort for not a lot of reward. Few games are sideways wiimote only, most that have the sideways option also have a gamecube controller option. And note that besides the wii games that absolutely require the wiimote and/or nunchuck, the gamecube...

Again, if truly all you want to know is if anyone has had the same issue (and from what we know from your first post and no further details, the issue is that your screen does not display video), I can answer: Yes. I suspect that's not what you actually wanted to know though, and without further...
