The Build Process

While initially conceptualized around a Raspberry Pi 4, the demand for higher emulation performance (like Dolphin) required a more robust approach. GameCathode integrates raw PC power into the shell of a classic TV.

  • Chassis Modification: Deep cleaning, discharging the CRT, and retrofitting a Minerva MT 5511 shell to house ATX/ITX components.
  • Native Analog Video: Bypassing modern HDMI converters by utilizing a legacy Nvidia GeForce 7300 to output a pure AV signal directly to the CRT.
  • Power & Thermal: Modifying a 300W power supply to fit the confined space and designing a custom airflow system to keep the recycled hardware cool.

Project Highlights

Pure CRT Experience

No digital-to-analog HDMI lag. The system outputs a native analog signal for pixel-perfect retro aesthetics.

Heavy Emulation

Unlike standard SBCs, the i7 core provides enough overhead to comfortably emulate demanding systems like GameCube.

100% Recycled

Built completely from workshop scrap and salvaged parts, proving that obsolete tech still holds immense value.
