Modder Transforms PlayStation 4 Slim into Portable Handheld Console

In a recent video, YouTuber Restore Technique unveiled a captivating endeavor: transforming a PlayStation 4 into a handheld device. Over the course of 27 minutes, he walks viewers through his intricate creation of a portable PS4 using a 3D-printed shell, custom circuit boards, a 7-inch display, and the original motherboard from a PlayStation 4 Slim. Measuring 249 x 156 x 49.2mm and weighing 1.7 kg, his project has caught the attention of those who see it as a more worthy successor to the PlayStation Vita compared to Sony’s streaming-only PlayStation Portal.

What sets Restore Technique’s project apart is its bold ambition. Unlike typical handheld mods, which often use less powerful Nintendo consoles like the GameCube or Wii, this one relies on the potent hardware of a PS4. The project shows off the console’s adaptability, as it still has enough power to run many games today—making it a significantly more challenging and rewarding endeavor. Central to this success is the PlayStation 4 Slim’s energy-efficient design that makes managing heat and power requirements much easier.

Delving into the technicalities, Restore Technique chose the Slim model for its smaller PCB. To fit everything neatly, unnecessary ports and components were removed using expert soldering tools, while a Dremel tool downsized the aluminum heat spreader. Additionally, a fan controller was incorporated to enhance cooling by allowing higher fan speeds. Even with these precautions, Restore Technique acknowledges potential overheating issues.

A DualShock controller has been seamlessly integrated, with many test points carefully wired throughout the device. Considering the energy demands, a substantial battery was necessary. Restore Technique crafted a 3S2P LiPo 12V 10,000 mAh battery pack, which can be safely charged and used simultaneously thanks to an upgraded 10 Amp DC power jack. DC buck converters help regulate the 12V and 5V power lines, ensuring the screen operates within safe voltage limits.

The video demonstrates the handheld in action, playing The Last of Us for 86 minutes, although it suggests pairing it with a charger for extended sessions. The high battery wattage, however, means it’s unsuitable for air travel. The project’s journey is meticulously documented, including the multi-step prototyping phase for the PS4T shell. Starting with FDM 3D printing, the final resin shell was crafted by PCBWay, selected for its heat-resistant properties.

During testing, the PS4T initially faced thermal and power issues, causing graphical glitches and slowdowns. After some adjustments, like replacing controller frames and enhancing electrical shielding, the device began performing reliably. This build combines electronics, 3D printing, and soldering in a true maker spirit, offering a fascinating glimpse into hobbyist ingenuity. It’s a must-watch for anyone interested in DIY tech projects.
