YouTuber Restore Technique has crafted an incredibly detailed 27-minute video showcasing a groundbreaking project: a handheld PlayStation 4. By employing a custom 3D-printed shell, meticulously designed PCBs, a 7-inch display, and the original motherboard from a PlayStation 4 Slim, Restore Technique has managed to build a truly portable PS4 device (measuring 249 x 156 x 49.2mm and weighing 1.7 Kg). Many enthusiasts believe this creation is a worthy successor to the PlayStation Vita, far surpassing the streaming-only PlayStation Portal.
The video goes in-depth on the development of this portable wonder, setting it apart from typical handheld console mods that often use less powerful hardware, like the Nintendo GameCube or Wii. This ambitious endeavor harnesses the strength of the PlayStation 4 and similar-era PC technology, which can still handle many modern games. The choice of a PlayStation 4 Slim was critical, as its low-power design made it easier to achieve the necessary balance between heat and power (TDP) for this handheld device.
In tackling this project, Restore Technique adopted a methodical approach. They selected a PlayStation 4 model known for its efficiency and compact PCB size. Essential ports and components were carefully removed and resized using top-notch soldering equipment, plenty of hot air, and a Dremel rotary tool. This was all done to shrink the size of the aluminum heat spreader that supports every motherboard component. Additionally, a fan controller was added to enhance cooling capability by increasing fan speed, though there are still concerns about potential overheating.
A standout feature of this build is the integration of a DualShock controller within the handheld, requiring numerous test points from the controller to be strategically rerouted. To power this creation, Restore Technique designed a custom 3S2P LiPo 12V 10,000 mAh battery pack, charged via an upgraded 10 Amp DC power jack. This allows for simultaneous charging and gaming. They utilized DC buck converters for the 12V and 5V lines, ensuring the screen operated at the correct lower voltage.
Well aware of the power demands, Restore Technique demonstrated gameplay footage, including an 86-minute session of The Last of Us, suggesting the console is best used while plugged in. The battery’s capacity is so high that carrying this device on most airplanes wouldn’t be feasible.
In the video, Restore Technique also details the step-by-step prototyping of the “PS4T” shell—PlayStation 4 Transport, as it’s referred to. Initially made with FDM 3D printing, the final resin shell was produced by PCBWay, providing the durability required for managing the high-heat demands of a portable PS4 Slim.
During initial tests, some thermal and power issues arose, leading to graphical glitches and slowdowns in several games. By replacing controller frames and enhancing internal shielding and heat management, the handheld now operates smoothly without any visual hitches.
This impressive project encompasses electronics, 3D printing, soldering, and embodies the maker spirit of learning through experimentation. It’s absolutely worth checking out for anyone interested in gaming innovation.
