link to iron pls I beg uDid you get a new iron/ tip? I too failed at motherboard rewiring/ trimming. With my old setup, It took me an hour to solder to my u10 and USB traces, and the connections were garbage. I also probably damaged the board, because areas of it turned black. At that point, I just bought a trim from SS.
Flash forward to yesterday. I busted out the busted board and my new iron with an ultra thin tip just to practice soldering to tiny things. I soldered solid connections to 8 vias right next to each other in about 5 minutes. Stripping the magnet wire took longer than attaching to the vias.
So when you do come back to this project, definitely at least get a tiny tip! Everyone says "Wow, I wish I'd done this sooner", and so will you.
Looking forward to seeing your next project, as well as finishing this one!
Btw you don't have to remove the on board regs to relocate U10/Bluetooth, but it would still be good to do so to test custom regs.Okay. Here’s an update.
I trimmed a new wii yesterday since my old trim was so fucked up i gave up on it. The new wii motherboard had a permanent short between the 1.15v line and gnd net to the gpu, since i accidentaly dremmeled next to it. It is dead as well. I just got a new wii motherboard working (the u10 and custom regs)

Yes, i removed all of the onboard regs first, so it was easier to check if my u10 is working. I will try to relocate bluetooth now, and then trim it. I wont do the full omg wtf trim since i dont need my wii to be that small so ill probably just cut a square around the cpu and gpu. This is wii number 9 so i really hope it works this time.

Yeah it was mostly to test custom regs then. Im almost finished with the bluetooth relocation so in about an hour i should be able to trim it.Btw you don't have to remove the on board regs to relocate U10/Bluetooth, but it would still be good to do so to test custom regs.
Shit me I did a fuck
I think my display driver board is dead.
I don't know why but the center chip heats up to the point that I can't touch it, after 3 seconds. It draws about 6 watts, even when the display isn't connected. It's an L7009 display. I know @Aurelio has one of those displays so maybe he can help me. Here are some pictures of the driver board:
Driver board by itself: (the MST703-LF chip is the one that heated up, it is the big chip in the center)

If any of the pictures isn't clear just tell me, I'll upload another one. Also, I would like to have this worklog moved back since there is a chance that I'll finish the portable in time (if I don't need to order a new display at least, since shipping takes ages)
If any off you know of any quick way to get a new complete display (l7009 or l7007hd) without waiting 20 days please tell me, I really want to finish this portable in time. Perhaps you @Aurelio know of a way, since you have one as well?
Also, I can't confirm if bluetooth is working since I don't have a gamecube controller nor a synced wiimote, and I can't sync a wii remote without a gamecube controller (maybe any of you knows a way to get to the system menu?)
Thanks a lot in advance.
edit:No, it was just turned on without video input displaying just a blue square with no signal on it.
Then it randomly shut off and stopped working. I really hope DX can ship me a new one in less then the 5 - 7 business days that it takes according to the shipping information. That is because the only other screen I currently have and can use is a 7 inch 480x234 display that only works with composite. I looks worse then a 240p youtube video.. If DX doesn't ship fast enough I don't think I'll be able to finish my portable in time.
Anyways I posted this post and the previous post in the wrong thread, so I'll move them over (just copy everything)
What gauge wire are you using on the data lines? You need at use 30ga or smaller or else it won't work. It looks like you're using 22 which is really for power lines.
Yeah ill redo those with magnet wire then
