Overview
- The one-off build by YouTuber 小宁子 XNZ, first shown in November 2025, is newly drawing wide Western attention this week with video proof of seamless operation.
- A triangular chassis centers a cast‑aluminum cooling core with a single fan, while an Arduino board routes HDMI and power so only one system runs at a time and switching takes roughly 3–5 seconds.
- A custom dock preserves Switch 2 handheld use, and space constraints mean the PlayStation and Xbox hardware function as digital-only with no disc drives.
- The creator used accessible methods—3D-printed patterns, gypsum molds, aluminum casting and copper contact plates—with testing showing about 60°C during a 30‑minute PS5 gameplay run.
- Positioned as a personal proof of concept with no sales plans, the system shares a 250W power supply that necessitates closing games before switching, and coverage has noted potential legal hurdles to commercialization.
