Modder Transforms PlayStation 4 Slim into Portable Handheld Console

YouTuber Restore Technique has released an incredibly detailed 27-minute video showcasing his own PlayStation 4 handheld project. By using a 3D-printed custom shell, tailor-made PCBs, a 7-inch screen, and the original motherboard from a PlayStation 4 Slim console, Restore Technique has crafted a genuine handheld version of the PlayStation 4. With dimensions of 249 x 156 x 49.2mm and weighing 1.7 kg, some argue this creation outshines the streaming-only PlayStation Portal as a true successor to the PlayStation Vita.

Throughout the video, Restore Technique highlights the distinctiveness of his Portable PlayStation 4 project. Unlike other handheld console modifications that typically involve less powerful Nintendo devices, his build ventures into more ambitious territory by utilizing a full PlayStation 4. This console and comparable PC hardware from the same era still support a range of gaming options. His choice of the PlayStation 4 Slim, which boasts an altered low-power design, assisted in achieving the necessary thermal and power balance for a portable console.

The meticulous approach taken by Restore Technique in this project is evident. He specifically chose the PlayStation 4 model with smaller PCB size due to its lower power requirements. Essential ports and components were carefully removed with precision tools, including the use of a Dremel to trim the aluminum heat spreader found on the motherboard. Additionally, he cleverly integrated a fan controller to regulate the fan speed beyond its original limits, though he’s cautious of potential overheating risks in the setup.

To bring enhanced portability, a Dual Shock controller was seamlessly incorporated into the handheld, directing numerous test point wires to various spots around the device. A robust battery was essential for this build, so Restore Technique assembled a 3S2P LiPo 12V 10,000 mAh battery pack. This system charges through an upgraded 10 Amp DC power jack, ensuring safe simultaneous gaming and charging. Voltage levels for the 12V and 5V rails are precisely managed by DC buck converters, essential for powering the screen operating at a lower voltage safely.

Gaming footage displayed in the video, such as playing The Last of Us for a remarkable 86 minutes, illustrates that this handheld is best paired with a charger for sustained playtime. However, due to its significant battery capacity, it might not be permitted on most flights.

Apart from transferring the PlayStation 4 Slim motherboard, the video elaborates on the prototyping journey for the “PS4T” shell. Starting with FDM 3D printing, the process evolved to finalizing the design with a resin shell produced by PCBWay, a choice favored for its compatibility with the high-heat demands of a portable PlayStation 4 Slim.

Following the initial assembly, the PS4T experienced some thermal and power issues that led to graphical glitches and slowdowns in various games. By replacing controller frames and enhancing internal electrical shielding and heat management, Restore Technique successfully stabilized his handheld, eliminating graphical issues.

This project is a fantastic demonstration of skill in electronics, 3D printing, soldering, and embodies the maker’s spirit of learning through experimentation. It’s a must-watch for any enthusiast.
