In a recently uploaded video, YouTuber Restore Technique has shown off his impressive new project: a handheld version of the PlayStation 4. Over the course of a detailed 27-minute video, he unveils how he transformed a PlayStation 4 Slim into a portable device, using a custom 3D-printed shell, specialized PCBs, and a 7-inch screen. The core of this creation is the original PS4 Slim motherboard, resulting in a compact device measuring 249 x 156 x 49.2mm and weighing 1.7 kg. For many, this custom handheld is leaps and bounds ahead of the streaming-only PlayStation Portal, earning it comparisons to a worthy successor to the PlayStation Vita.
As demonstrated in the video, this DIY project sets itself apart by using more robust hardware than typically seen in similar mod projects, which often incorporate Nintendo GameCube or Wii components. By comparison, the PlayStation 4’s specifications allow it to run a broader range of games, making this endeavor more audacious. Restore Technique chose the PS4 Slim specifically because of its energy-efficient design, which balanced the necessary thermal and power dynamics to fit into a handheld format.
Careful planning went into every aspect of this build. Restore Technique strategically selected a lower-power PS4 model with a smaller PCB, removing unnecessary ports and components using advanced soldering stations and a Dremel tool to trim down the aluminum heat spreader. Additionally, a fan controller was implemented, allowing the fan speed to exceed factory settings, although there are concerns about potential overheating issues.
Integrating a DualShock controller into the handheld required expert wiring, rerouting connections to function within the confines of the portable setup. To ensure sufficient power, a custom 3S2P LiPo 12V 10,000 mAh battery pack was created. This hefty battery charges via a DC power jack, upgraded to a 10-amp model, to accommodate charging while gaming. Various DC buck converters manage the different voltage demands of the system, particularly for the 12V and 5V rails necessary to operate the screen safely.
The video features gaming footage, showcasing The Last of Us running for over an hour, highlighting the system’s powerful performance. However, Restore Technique notes the handheld is best played while plugged in due to its significant power consumption. The battery’s substantial output also means this console wouldn’t pass airport security for air travel.
In crafting the “PS4T” shell, the project involved a multi-step prototyping process, beginning with FDM 3D printing before moving to a final resin shell produced by PCBWay. This material selection ensures the shell’s durability under high-heat conditions, essential for a portable console like this.
Following initial assembly, some issues with thermal and power management caused noticeable glitches and slowdowns in games. These were resolved by replacing controller frames and improving both electrical shielding and heat dissipation, leading to stable gameplay without visual hiccups.
This project highlights a passion for electronics, 3D printing, and the maker spirit of trial and error. It’s a fantastic example of creativity and problem-solving in action, making for a compelling watch for anyone interested in gaming and tech innovations.
