The DS for the TFP410 has a lot of helpful layout recommendations, including decoupling the various power supplies: The recommended decoupling cap networks are likely critical for a sensitive high-speed application like this. DVI also uses differential signaling, so signal traces are paired...

I'm eager to see if you can get them working. I ordered a couple a few weeks ago and couldn't get them to work on untrimmed or trimmed mobos. A deeper read into the DS indicates that the ER line might need to be pulsed to start the POR timer, but it also says that you can tie ER to GND if it's...

I assembled my new PCBs! I squeezed a DSBGA LDO onto my audio amp board to get more powerful speakers without making the board larger. Unfortunately, my cheap knockoff AVRISP can't program the microcontroller since it's running at 1.8V. I'm getting a new programmer in the mail tomorrow that...

The U10 is a supervisory IC that generates a delayed 3.3V signal. It sends the signal to the Wii's Hollywood, letting it know that it's good to go to boot up. Edit 2024-05-13: My old explanation was flawed. For future travelers: U10 holds its output LOW to keep the Hollywood in reset, until the...

Yeah, space is really tight in this case. The shoulder buttons are just bumpers with dual-action tacts on platforms. No hinged memes for me. I'll post a video of the setup eventually. The plan is to suspend the LCD driver and the PMS in a 3D-printed frame in the space between the mobo and the...

I got off my lazy ass this winter and purchased a Prusa i3 MK3 to help revive my UltraWii project. Casework is the hardest part of portablizing for me, so 3D printing is helping me overcome that final hurdle. The case is actually smaller/thinner than the Polycase SL53, but still has fullsize GC...

Hey, I listen to rain & thunderstorms when I'm studying, too! I listen to oldies, mostly 60s/70s/80s music, including classic rock, southern rock, R&B, and a lot of soul, funk, and disco. I also listen to classic jazz, like John Coltrane, Elvin Jones, and Charles Mingus, plus some modern big...

Thanks for doing this work, Aurelio. It's really fantastic. Purely out of curiosity, I wonder if Metroid: Other M could be played using this homebrew and a special input scheme. Could holding the left trigger switch the emulated Wiimote to the vertical/pointing orientation? Then releasing the...

Double-posting because I have too many attachments. Here's how the software VGA looks on the 3.5" 640x480 LCD. (V is for vaseline filter... Why, Nintendo, why?!)

I know this hasn't been much of a worklog, but unfortunately my job and other commitments do take precedence over portablizing. I do have some backlogged updates to share, however. In my quest for the ULTIMATE in 3.5" Wii portable video quality, I'm using the PD035VX2 640x480 panel. The only...

Welcome to BitBuilt! Lots of people, including Gman, Bakuku, and Bungle have made portables in Wii U gamepads. They're ergonomic, but you're right that you'd need a spacer or extra compartment to hold everything. It's probably possible to fit a Wii in a stock gamepad, but I don't suggest trying...

I use this when trimming, sanding and using Bondo. Works great and is well worth the money if it keeps me from getting lung cancer.

I got into retro emulation and hardware, then into hardware modding, and eventually into portablizing. Right now, I'm getting my BSEE and I work at a local makerspace. My portablizing/practical knowledge has gotten me gigs writing EE curriculum with my professors, which is pretty cool. EE theory...

Stitches is totally right. I did some searching and the AM7331 is a digital picture frame SOC. The SOC contains a CPU, LCD driver, and some other interesting modules. Here's a PDF with a pinout of the AM7331 if you're interested. As the pinout shows, this IC was specifically made to read in data...

This looks awesome! I've been hoping someone would recase a mobile device, since they're generally more powerful than cheap SBCs. Any plans to increase battery capacity?

Well, the time has come to post my 2018 summer contest entry worklog. This bad boy has been in the works for a while. Here's the long list of sexy features: - OMEGA-trimmed RVK mobo (maybe just "near-OMEGA," we'll see what the case wants) - Polycase SL-53 case, making this one of the smallest...

Looks awesome. I'm really stoked to see a pure-Wii portable with Wiimote controls! And good luck spoofing the Wiimote IR signals. It's standard I2C, shouldn't be too bad.

The red board is only good for 2 cells in series (2S.) You can add more cells in parallel (2S2P, 2S4P, etc.) but not more cells in series. If you decide to trim the mobo and use custom regulators, you can use the batteries in 2S2P with the red board. If do not trim the Wii you cannot use the red...

The Odroid XU4 is a good choice. A little pricier than a Pi, but it emulates N64 and Dreamcast very well.
