Hey everyone! I'm trying to build a portable Wii to play Gamecube games, but I'm running into issues when trimming the board and I need help. I'm reading low resistances when measuring across the 1.8V, 1.15V, and 1.0V nodes to ground. I've spent a while sanding the sides but I'm not making much progress in getting the resistance to change (aside from 3.3V). The Wii did power on properly with the U10 relocation before trimming. I attached some pictures below if that helps.
Resistances measured from V+ to GND:
I also had some other questions about making a portable Wii:
Resistances measured from V+ to GND:
- 3.3V - 8.3kΩ
- 1.8V - 38Ω
- 1.15V - 53Ω
- 1.0V - 12Ω
I also had some other questions about making a portable Wii:
- Are the analog sensors for the L and R buttons required, or can I just use tactile switches?
- Does anyone have any good heatsinks that work for the Wii? I was looking into getting a laptop heatsink, maybe one more common that could be bought for very cheap. I was looking at the Dell Lattitude D600 heatsink earlier.
- I found these nice little buck converters that use a castellated PCB design so I can surface mount them onto a custom PCB. Anyone have any thoughts on these regulators?
- Are there any USB PD modules to use with a 2S lithium battery pack? I saw someone mention a guy custom making them, but that's the only mention of one that I have seen.
