In a remarkable feat of ingenuity, YouTuber Restore Technique has unveiled a handmade PlayStation 4 handheld device in a comprehensive 27-minute showcase. This venture involved crafting a custom shell via 3D printing, integrating unique PCBs, a 7-inch display, and utilizing the PlayStation 4 Slim motherboard. The result is an impressive portable console measuring 249 x 156 x 49.2 mm and weighing approximately 1.7 kg. Fans might argue that this creation is a fitting follow-up to the PlayStation Vita, especially in the wake of the streaming-only PlayStation Portal.
Diving into the details, the video highlights how this handheld project differentiates itself by incorporating the more powerful PlayStation 4 console, unlike many other mods that often stick to Nintendo consoles like the GameCube and Wii. The system is even able to run a variety of games thanks to its robust PC-like hardware. The PlayStation 4 Slim, chosen by Restore Technique for its energy-efficient design, turned out to be ideal for achieving the necessary heat and power balance required for portability.
Restore Technique approached this build meticulously, opting for a PlayStation 4 model with a smaller, more efficient PCB. To fit all the essentials in the custom design, some components were carefully desoldered using top-tier stations and modified tools like a Dremel were used to trim down the aluminum heat spreader. A fan controller was also added to optimize cooling by pushing the fan beyond its standard speed, though the creator notes that overheating could still be an issue.
The project features an integrated DualShock controller with numerous wires linked to various test points, creating a seamless gaming experience on the go. Powering this beast is a colossal 3S2P LiPo 12V 10,000 mAh battery pack, custom-built by Restore Technique. This is paired with a 10 Amp DC power connector, allowing for simultaneous charging and gaming. The inclusion of DC buck converters skillfully stabilizes the voltage, ensuring the screen’s lower voltage requirement is met without mishap.
The demonstration also includes snippets of gameplay, such as an 86-minute session of The Last of Us, indicating that for optimum use, especially during long sessions, keeping the device plugged in is advisable. Interestingly, the TSA might frown upon this hefty setup due to the battery’s high wattage if you were thinking of taking it on a flight.
From prototyping to final production, the journey of crafting the “PS4T” or PlayStation 4 Transport, is thoroughly chronicled in the video. Initial designs were printed with FDM technology before a sturdier resin shell was manufactured by PCBWay, tailor-made for handling the thermal demands of this portable setup.
During the development process, some technical hiccups with thermals and power caused graphical glitches and slowdowns. However, through refining the controller supports and enhancing electrical shielding and heat management, these issues were resolved, resulting in a stable and glitch-free gaming experience.
This project stands as a testament to innovation, blending electronics mastery, 3D printing skills, and perseverance in the maker community. It’s an inspiring project worth checking out for anyone interested in the intersection of tech and creativity.
