Worklog FailMii "Portable" Wii Project! (Functional)

[zerotech00]

Hey guys , in this thread post i'll basically document all my steps for creating my first ever wii portable, for anyone who wants to know what parts i've bought and i'm using, here's a list with them:

1x Untrimmed Wii Family Edition Motherboard (it has 4 layer board and low consumption which is exactly what i need for my project, and also i won't trim it due to the risks of it and lack of experience with very micro soldering)
1x DC UPS 5V 9V 12V Output 6x 18650 Battery (to power on the wii, screen and other stuff via 5v usb port and 12v3a port in which the wii power cable will go in)
1x Wii to USB-C cable (for power)
1x Wii to HDMI cable (for source output for the screen)
1x 7 inch Screen with HDMI and powers on via Micro-USB cable
1x 16GB USB Flash Drive (for RVLoader, Games etc)
1x USB-C to 5*5x2.1mm adapter (so i can plug it in my UPS/Power bank)
1x Teared down WiiMote with every single button wired to an individual SW Switch
1x Teared down Nunchuk with the 2 trigger buttons wired to an individual SW Switch
1x 1 USB Male to 3 USB Female cable (to plug most of the USB stuff in that i need)
1x Mini Speaker (for sound ofc)
1x 4K x 2K Video Audio Extractor HDMI with 3.5mm jack port (so my speaker and screen can both work as my screen doesn't have built in speakers)
1x HDMI 90 degree angle adapter (since currently the hdmi cable in the screen hits the micro-usb cable due to it's need for micro-usb power too)
1x 2 in 1 USB Hub (just in case)

i know it sounds like quite a lot of stuff to fit in a case, but trust me, it's not that hard if you plan on how to lay the cables in etc etc, and ofc if you don't care that much about the spaghetti stuff that you'll have inside the portable at the end, nonetheless i'll attach 3 pictures with the 3d cad main case, top part with the trigger/buttons and the part with the screen and it's face buttons

Extra: i'll also attach a picture with the wiimote's individual button rewiring to SW Switches

Current situation: i sent the wii family edition motherboard, wiimote, nunchuk and everything else to my 3d printer guy so he can make the holes for the buttons (i'm not that good with making stuff in 3D Cad and since he has experience with this stuff, i gave him this sidequest ) ) and overall make some adjustments to the case and etc, i'll give more updates once the case is somewhat done

A bit of an update: My 3D Printer Guy started printing the Screen Part & Shoulder buttons for my FailMii Portable project, i'll do more updates as soon as i'll have more things to announce, including the final thing

Another update: The case was officially printed (both the base, faceplate and the 3 shoulder buttons), the only problem is:
For some reason, the cooling of the wii family edition motherboard is hitting the area where the screen will have to sit, so because of that, i told the 3d printer guy to somehow raise the base of the case a bit higher (just raise the bezels) so the screen is not gonna hit the cooling of the wii family edition motherboard at all, and to also print another small case for the power bank (18650 power bank) as my original plan of just letting it be in the case around unfortunately won't work, and that's gonna be all the modifications needed (hopefully), i'll give more updates if i have anything new to share about the project

A bit of an update: I got the case from my 3d printer guy, however I had to modify the case a bit, so the nunchuk hole would be lower as it was hitting the hdmi port on my 7 inch screen, and also I installed the nunchuk with hot glue (hopefully that's gonna hold it well on the case), and so far it's going great, slow but good progress

I don't think you'll need to worry about that nunchuk PCB going anywhere, but I would recommend trying double sided tape sometime. You can get it strong enough to where something like this won't come loose too easily, but you can still get it off if you really want to (I.E. use a bit of IPA). I've had issues in the past where I used so much hot glue, it warped the print of what I was working on. Between that, it being a nightmare to get off, raising the component up a bit, and giving less polished results, I'd definitely recommend trying double sided tape.

Another FailMii update: I almost finished attaching all the sw buttons, I do need to order extra ones for the dpad & also wait for the power cable of the FailMii to arrive, and other than that, I'm pretty much 70% done with the project

 

[zerotech00]

So it's been well over 2 months, unfortunately the failmii hasn't been completed yet because i messed up the failmii case dimensions and when i tried to get everything in (including the wii mobo itself, the wiimote mobo, lots of wires and adapters etc), the front panel wouldn't close itself due to those cables and adapters pushing out since there wasn't much space for all of those things in.

I finally decided to redesign the whole failmii case (basically just the base & front panel), this time i made proper holes for the failmii front panel buttons and i resized it just a bit bigger and i also resized the height so i can be 100% sure that i'll be able to close up the case without the cables & adapters pushing out of it.

I'll give more updates as soon as my 3d printer guy will finish printing the new case (i really hope he will agree doing another print again lol)

 

[zerotech00]

New update: the 3D case was made for the FailMii and I also got my usb-c to Wii power cable & AV to HDMI cable as well for video and audio, currently I am very sick (got a flu) and I really can't work on the project yet, but as soon as I'll be healthy again, I'll start documenting the whole process (I'll probably make a YouTube video with the process/journey too) and give the final update, that's all for now, I really can't wait to finish this project once it for all!

 

[zerotech00]

This is my last time I'll ever post here: I tried with another Wii motherboard and once again, I ended up bricking this one too and it only shows no signal on the screen, atp I'm happy I at least tried and I'll never ever try to make a Wii portable again, period...

 

[zerotech00]

Nevermind, it actually works now!

I decided not to give up forever and I actually managed to fix it, I'm assuming there was some debris underneath the Wii mobo and that's what probably prevented it from working properly, regardless now it actually works and I'm really proud of what I managed to achieve!
