YouTuber Restore Technique has really outdone himself with an incredibly detailed 27-minute video highlighting his latest creation: a handheld PlayStation 4. By using a custom 3D-printed shell, personalized PCBs, a 7-inch screen, and the original motherboard from a PlayStation 4 Slim, he’s managed to craft a truly portable gaming device. Measuring 249 x 156 x 49.2mm and weighing 1.7 kg, this handheld marvel is arguably a superior successor to the PlayStation Vita, especially when stacked against the streaming-only PlayStation Portal.
Within his video, Restore Technique elaborates on the nuances of his Portable PlayStation 4 project. Unlike the typical mods that use older consoles like the GameCube or Wii, this project showcases the power of a PlayStation 4. The PS4’s performance is on par with the PC hardware from the same era, allowing it to handle a wide array of games, setting this project apart in ambition and capability. The chosen PS4 Slim model, with its energy-efficient design, provided an advantage, making it easier to achieve the desired heat and power balance for this handheld iteration.
He meticulously selected a PS4 variant with a compact PCB, consuming less power. The process involved removing several components with precision tools, including top-notch soldering stations and a Dremel rotary tool, to minimize the aluminum heat spreader that connects the motherboard components. Ingeniously, a fan controller was included to cool down the system by accelerating the fan beyond its normal speed, although overheating might still be a potential issue.
The integration of a Dual Shock controller was another intricate part of the project, involving a lot of innovative wiring from the controller to various new parts of the handheld. Recognizing the power needs, Restore Technique designed a custom 3S2P LiPo 12V 10,000 mAh battery pack. This setup allows for charging and gaming simultaneously through a reinforced 10 Amp DC power jack. To manage the different voltage requirements, DC buck converters were used to supply both 12V and 5V, protecting the screen from any damaging overvoltage.
Though limited gameplay footage was shared—including a segment where he played The Last of Us for 86 minutes—the handheld’s hefty battery consumption makes it better suited for use with a charger nearby. Restore Technique also pointed out the battery’s high wattage could make air travel challenging, as it likely wouldn’t meet most airlines’ carry-on limits.
In the video, beyond just transplanting the PS4 Slim motherboard, he goes into depth about the multi-step prototyping for the so-called “PS4T” (short for PlayStation 4 Transport). Using FDM 3D printing initially, he eventually had a final resin shell manufactured by PCBWay, finding it more suited to handling the device’s high-heat demands.
During initial testing phases, the PS4T faced some thermal and power hurdles, leading to graphical issues and slow performance across various games. However, after replacing controller frames and enhancing both internal electric shielding and heat dissipation, performance smoothed out without any graphical hiccups.
This project stands as a testament to creativity, blending electronics, 3D printing, and soldering while embracing the spirit of building and refining through trial and error. It’s an inspiring endeavor, well worth checking out.
