Modder Builds Portable PS4 Slim Handheld for Local Game Rendering
The modder built a portable PlayStation 4 system which can render games without needing to access any other content. The modder wewillmakeitnow developed a portable PlayStation 4 Slim handheld system because the official PlayStation Portal only supports game streaming. The personal DIY project functions as a complete console which enables local game rendering contrary to the capabilities of Sony's existing product.
Core Modifications and Engineering
The device base uses a Sony PlayStation 4 Slim motherboard which underwent extensive modifications. The modder developed the board trimming method to create a smaller design without losing its original functions while making the system more power-efficient and cooler. The PS4 APU temperature control system includes a custom cooling solution that utilizes specially designed airflow paths and heatsink structures to operate under maximum performance conditions.
The system uses an ESP32 microcontroller which has custom firmware to manage real-time operations by monitoring temperature and power consumption and overseeing battery charging and executing safety shutdowns.

Display, Battery, and Performance
The handheld device features a 7-inch OLED display with 1080p resolution which produces high-contrast visual output. The battery system consists of six 21700 cells which deliver around 130 Wh of energy capacity.
The battery life estimation depends on the active game requirements:
- Less Demanding Games: Approximately 2.7 to 3 hours of gameplay.
- The gameplay duration for demanding games reaches 1.3 to 1.5 hours.
- The system automatically conducts safe shutdown procedures when it reaches low voltage levels to prevent any damage to battery cells.
Connectivity and Enclosure
The device maintains its capability to project images on external screens through its HDMI output, which operates like a basic PS4 system. The system includes multiple USB ports which allow users to connect controllers and external hard drives for extra storage space.
The enclosure was custom-designed for a compact form factor and 3D printed in ABS for durability and heat resistance. The design establishes airflow patterns and designates space for user functions and system maintenance activities.
Project Status
The creator has stated that this is a personal project and is not for sale or intended for mass production. 3D print models and detailed build guides remain unavailable to the public at this time. The project exists as a personal engineering challenge which I created because of my curiosity and passion for engineering work.
