Could you build this?
No This project requires custom 4-layer PCB design, microcontroller firmware development, CNC-machined aluminum hardware, and physical hardware assembly.
What it would actually take: Building this device requires schematic capture and 4-layer high-density PCB layout in KiCad, component selection (ATtiny1616, LED matrix drivers), surface-mount assembly, and embedded C firmware for matrix multiplexing and game logic. Additionally, it requires mechanical CAD design and CNC machining for a custom aluminum enclosure, along with compiling embedded logic to WebAssembly for browser emulation. It demands cross-disciplinary electrical engineering, firmware programming, and mechanical machining expertise.
