In a fascinating endeavor, YouTuber Restore Technique showcased an incredibly meticulous 27-minute video that walks us through their own PlayStation 4 handheld creation. By combining a carefully 3D-printed custom shell, several custom-made PCBs, a 7-inch screen, and the original PlayStation 4 Slim console motherboard, they managed to assemble a genuine handheld PlayStation 4, measuring 249 x 156 x 49.2mm and weighing 1.7 kg. Compared to the streaming-only PlayStation Portal, this innovative project stands out as a remarkable follow-up to the PlayStation Vita.
The essence of this project was leveraging a stronger console than the typically modified Nintendo GameCube and Wii systems, such as the Nintendo Kawaii and the pioneering handheld Xbox. The PlayStation 4, along with equivalent PC hardware from that era, still runs a variety of games smoothly. Thus, Restore Technique’s project is significantly bolder. Aiding in this endeavor is the PlayStation 4 Slim’s low-power design which simplifies achieving the desired thermal and power balance for this handheld system.
Meticulous planning and execution were key to this handheld marvel. Restore Technique opted for a PlayStation 4 model with a smaller, energy-efficient PCB. Numerous ports and components were artfully removed using top-tier soldering equipment—lots of hot air was involved in the process—and a Dremel tool resized the aluminum heat spreaders, supporting all motherboard components. Additionally, a fan controller ensures the system remains cool by enhancing its speed beyond the factory settings, although there’s a note in the video that overheating might still occur.
Not stopping at just the console, Restore Technique flawlessly integrated a DualShock controller into the handheld, skillfully rewiring from numerous test points to their new placements. The device’s portable nature necessitated a substantial battery, which led to the creation of a custom 3S2P LiPo 12V 10,000 mAh battery pack. The improved DC power jack, capable of handling 10 Amps, facilitates both charging and gaming simultaneously, while DC buck converters modulate power for different voltage rails handling the screen without risking overvoltage.
Within the video, Restore Technique illustrates gameplay, including an 86-minute session of “The Last of Us,” noting the handheld serves best with the charger due to its high energy demand, making it unsuitable for air travel with most airlines.
The comprehensive video also delves into the multi-step prototyping for the “PS4T” (purportedly standing for PlayStation 4 Transport) shell, starting with FDM 3D printing and concluding with a resin shell produced by PCBWay for enduring high thermal conditions.
Initially, performance hiccups like graphical glitches emerged, linked to thermal and power management issues. However, after replacing certain component frames and boosting internal shielding and heat dispersion, the handheld achieved stable operation.
This project doesn’t just highlight impressive technical prowess; it embodies a maker’s spirit of learning from attempts and setbacks. It’s certainly a venture worth following for anyone interested in modern console modifications and creative tech solutions.
