If you have a means to flash the PMS firmware you could change it to support 9V 2A instead if you really wanted to

Check out PAM8803

I've been working a lot on this project lately. Unfortunately no pretty pictures to show, since I've been working entirely in software. I got started learning the PIC environment since this is my first time working with this controller. I picked up this MPLAB Xpress DM164140 evaluation board to...

Looks hot

I believe @Noah was saying there's a problem with international shipping right now on the store and that there are cheaper options. I wouldn't really say using the pth regulators + red board is any more diy since the pth regulators are a preassembled part that you just add a resistor and a...

That's a huge improvement! I look forward to seeing how it turns out in the end!

400 degrees is way too high. I use 315C for everything except for working with the ground plane. If your solder doesn't melt at 400C then your iron is a piece of junk and you should replace it, preferably with a reputably branded soldering station like Weller or Hakko. Especially if the chip...

To elaborate on some points: A 6 layer board uses almost twice the power of the 4 layer so you'll get around half battery life and will require a more robust cooling system, therefore 4 layers are highly recommended. The PMS is also great to have because not only does it replace the PTH...

You probably don't need to give up on the Wii yet. Check if the input pin is continuous with 3.3v. That pin should be getting 3.3v unless you messed up the input pad. Once the input pin is getting the proper 3.3v, then you can make the evaluation on whether the U10 chip is broken or not. If it...

Check the input pin, if it reads 3.3v, you can try disconnecting the wire on the on the output pin. If the output pin doesn't read 3.3v, the U10 is probably broken, in which case you can replace it with U9 if you still have it.

Well if the u10 is not showing 3.3v on the output then it definitely won't turn on. You should pick up some magnet wire as that wire you're using is probably too large to be effectively used. You should also use some flux to clean up those nasty solder joints, solder joints should be smooth, not...

Clearly I didn't make it in time for the contest. I didn't start this project with the contest in mind, it was more of a "it would be nice if I happen to finish" kind of thing. I'm planning on making this portable among the best there ever was, and in order to make no compromises I had to give...

If the output pin of u10 is outputting 3.3v it's probably not broken. You can power on and measure the voltage on the via to check.

Your wire is going to the wrong pin on U10

The memory card ports are going to be really hard to remove by desoldering them, this is my personal technique: Get some flush cutters and cut the pieces of metal that connect the metal shield to the board. Once you do that you can bend the shield upward to expose the pins. I then cut all the...

It's possible that the 3.3v short is not caused by the edges of the board. Thoroughly inspect the board and see if there's any small pieces of solder that could possibly be shorting somewhere on the 3.3v area of the board. You can also try cleaning the board with 90+% IPA. From the looks of it...

Did you even try the things I mentioned?

Depends on the TV. It shouldn't be less than 10 ohms, but it's normal for the resistance to be relatively low. It seems you've been stuck with the same problems for quite some time now. I'll try to make this as clear as possible: If you're getting < 10 ohms to gnd on any of the power lines you...

Also there's a lot of productive (as well as unproductive) conversation in the Discord channel that's worth joining.
