PS4 Slim Turned Handheld: 7″ OLED, 3-Hour Battery, HDMI Out
▼ Summary
– A Reddit user built a portable PS4 handheld by modifying a PS4 Slim’s motherboard, adding a screen, controls, and a custom 3D-printed shell with a battery and microcontroller.
– The device features original PS4 controls, a small monitoring screen, LED-backlit buttons, and a 7-inch OLED display, though its ergonomics are noted as a weak point.
– Key technical challenges included shrinking the motherboard and designing a new power delivery and cooling system, managed by a microcontroller for thermal and voltage safety.
– It is powered by a large 130Wh battery, providing 1.5 to 3 hours of gameplay, and includes HDMI output and USB-C ports to function as a stationary console.
– The creator describes the project as a personal engineering challenge, not for mass production, with the shell made from 3D-printed ABS plastic and room for future ergonomic improvements.
A dedicated hobbyist has successfully transformed a standard PlayStation 4 Slim into a fully functional handheld gaming device, showcasing a remarkable feat of custom engineering. This portable console integrates a 7-inch OLED display, a custom 3D-printed chassis, and an internal battery system, offering a unique take on mobile PlayStation gaming. While not intended for commercial release, the project highlights the impressive potential of dedicated modding communities to reimagine existing hardware.
The device, shared by a Reddit user, presents a distinctive hybrid aesthetic reminiscent of classic handhelds like the PSP and Nintendo DS. It incorporates what appear to be original PS4 controller components, including the analog sticks and face buttons, which are backlit with embedded LEDs. A secondary, smaller screen in the lower-right corner provides real-time monitoring of system power and temperature data, managed by a custom-programmed ESP32 microcontroller.
This joins a small collection of similar DIY endeavors found online, where creators attempt to miniaturize home consoles. A notable inspiration was a portable Xbox 360 build, with this PS4 version similarly omitting the optical disc drive to reduce its overall size. The core technical achievement involved significantly trimming down the PS4 Slim’s motherboard while preserving its essential functionality, necessitating a completely redesigned power delivery and cooling solution.
Thermal management is handled by a rear-mounted fan, with safety cut-off fuses controlled by the onboard MCU to prevent overheating. The system is designed to automatically shut down power if it detects a 10V surge, protecting both the internal components and the battery pack. The builder emphasized that the goals extended beyond mere miniaturization to also achieve improved power efficiency and better thermal performance.
Power comes from a substantial battery comprised of six 21700 cells, offering a combined capacity of approximately 130 watt-hours. This provides an estimated 2.7 to 3 hours of gameplay for less demanding titles, drawing about 44 watts per hour. However, running graphically intensive AAA games can reduce that battery life to roughly 1.5 hours. It’s worth noting that the battery’s capacity exceeds standard airline limits for carry-on luggage.
Despite its portable nature, the device retains console-like connectivity. It features an HDMI output port for connecting to an external television or monitor, effectively allowing it to function as a standard PS4 when docked. Three USB-C ports and the original DualShock 4 wireless antenna are also included, facilitating controller pairing and peripheral connections. A barrel jack input ensures the system receives full power when operating in this stationary mode.
The creator describes the project as a personal engineering challenge rather than a prototype for manufacturing. The current shell is 3D-printed from ABS plastic with a glossy finish, though earlier prototypes from the builder’s post history suggest more ergonomic designs are possible. While the handheld is fully operational, its form factor indicates there is still room for refinement in future iterations, underscoring the ongoing, iterative nature of such ambitious custom hardware projects.
