Where can I find the discord for this? I work as a machinist and could get the shell made in house, I'm super interested in making one of these

The Kawaii doesn't have a discord made for it specifically, but the BitBuilt discord is the next best thing! Check the front page of the forums on the sidebar for a join button in the embed.

I hope it have a part that I can put it in and it would work as a wii sensor bar.

This feels like a challenge for me to go smaller... Wait, is there even a smaller motherboard trim?

Also, who should I beg if I want to buy one?

(I'm 53% sure I'm using this website correctly)

Awesome work on the Kawaii! This is the only Wii build I have seen that uses the Hollywood-2 revision of the Wii Mini. How many watts do you think the final trim will pull?

The Kawaii made its public debut at the 2025 Midwest Gaming Classic last weekend!

It was connected to an HDMI monitor via my Retrotink 4K. Being able to pop it off the dock and hand it to people was really special. Many folks had seen it online, and were super excited to hold it in person!

Here are some better photos of the Kawaii and dock.

Unfortunately, I couldn't get Thundervolt's RGB LED control working in time for MGC. As a stopgap solution, I wired up a MaplePad RP2040 board I had lying around. The LEDs and MaplePad are hot glued in. The final RGB LED PCBs will fix this jankiness.

Some details about thermals:

• With the 20x20x6mm fan dock, the Hollywood-2 Kawaii "stabilized" at 60°C board temp, ~50°C external temp.
  • While this was 15°C lower than the Hollywood-1 Kawaii, it still wasn't cool enough for users to touch the unit while it was on
  • The tiny fan was kinda whiny. And the Wii still crashed if the ambient temp was high enough (>24C)
• At MGC, I used the original fanless dock, and had an external 5-inch fan blowing on the Kawaii at all times.
  • This kept the internal board temp at 40°C or less the whole time! External temps were 30-something degrees
  • People were able to touch and handle the unit with this setup, which was great!
• On achieving passive cooling:
  • Wesk and I played around with enlarging the dock to fit a bigger fan, but honestly I don't like how the bigger docks looked.
  • A copper Kawaii (with silkscreened graphics?) might solve the thermal issues, at the cost of aesthetics.
  • Increasing the aluminum shell's fin count, delidding and liquid metal probably wouldn't make much of a difference.

For me, this project was always a meme build / OMEGA showcase, rather than something meant to be used on a daily basis (build a Short Stack or GC Nano for that!) The Kawaii really is a piece of electronic jewelry more than anything else. As such, I am very satisfied with the current state of the project, even if it's not 100% passively cooled.

I'll design and order the RGB LED PCBs soon. Once those are tested, everything will be open sourced on my GitHub! After that, I'll look into doing a group order of anodized shells.

Extreme beauty of craftsmanship, fantastic, I'm going to build one.

too hot to handle

Can’t wait to build one of these bad boys

Wish I could've been there this year, this was a really special project that you guys put together. I'm glad it all went well, and am always extremely impressed by your work. Great job!
