YouTuber Restore Technique recently unveiled a remarkable project: a handheld PlayStation 4 that he crafted himself. In a 27-minute video, he meticulously explains how he managed to build this device using a custom 3D-printed shell, specialized PCBs, a 7-inch screen, and the original motherboard from a PlayStation 4 Slim. The result? A portable PlayStation 4 measuring 249 x 156 x 49.2mm and weighing around 1.7 kg. Many enthusiasts argue that this creation surpasses even the streaming-only PlayStation Portal, making it a worthy successor to the much-loved PlayStation Vita.
The video showcases an array of images that chronicle his journey, starting with a concept illustration of the components necessary for the transformation of a PS4 Slim into a portable unit. It’s not just a novelty—Restore Technique’s project distinguishes itself by leveraging more powerful hardware than typically seen in such mods. While many modders often gravitate towards Nintendo consoles like the GameCube or Wii for custom handheld projects, Restore Technique raised the bar by diving into a PlayStation 4.
In the video, Restore Technique goes into detail about the careful selection of a PlayStation 4 model that consumes less power—a crucial decision that supported the overall design goals. The process involved removing certain ports and components with expert soldering techniques and using tools like a Dremel to reshape the aluminum heat spreader for efficient cooling. To further manage the temperature, a fan controller was included to push the fan beyond its original capacity, though he notes that overheating could still be an issue.
To bring controller functionality to this new portable device, he ingeniously integrated a DualShock controller directly into the system. This required extensive wiring from various test points of the controller to different locations within the handheld console.
Powering the device demanded a robust solution, so Restore Technique developed a custom 3S2P LiPo 12V 10,000 mAh battery pack. Charging is managed through a DC power jack, with upgrades to handle simultaneous charging and gaming. Proper voltage control is achieved with DC buck converters, ensuring the 7-inch screen operates without risk of overvoltage damage.
The video doesn’t just talk about the build; it includes footage of him playing The Last of Us for 86 minutes, demonstrating the device’s capabilities and the importance of keeping it plugged in during extensive play sessions. However, he cautions that the high-wattage battery could pose issues with flight regulations, so keep that in mind for air travel.
His project wasn’t without challenges. Early tests revealed thermal and power issues, leading to graphical glitches and performance slowdowns. But with perseverance, he improved the frame construction, bolstered internal electric shielding, and enhanced heat dissipation to achieve stable performance.
For those passionate about electronics, 3D printing, soldering, and the DIY spirit, this build is a fascinating case study. It combines technology, craftsmanship, and innovation, making it a must-see for anyone interested in gaming modifications.
