Could you build this?
No Designing custom multi-microcontroller hardware with hardware genlocking (3x RP2350B), HDMI pixel generation, and custom Lua bare-metal VM execution requires advanced electrical engineering and low-level firmware skill.
What it would actually take: Requires PCB design (KiCad) with high-speed differential pairs for DVI/HDMI signaling, clock distribution and phase synchronization across three RP2350 microcontrollers, and custom PIO (Programmable I/O) state machines. The software demands bare-metal C/Assembly firmware, a custom scanline compositor, and an embedded sandboxed Lua interpreter running without an OS.
