YouTuber Restore Technique has recently showcased an exceptionally detailed project in a 27-minute video, revealing his homemade PlayStation 4 handheld console. By utilizing a custom 3D-printed shell, specialized PCBs, a 7-inch screen, and the original PlayStation 4 Slim motherboard, Restore Technique successfully crafted a genuine handheld PS4. The final product measures 249 x 156 x 49.2mm and weighs 1.7 Kg. For many, this inventive creation leaps beyond Sony’s streaming-only PlayStation Portal and stands as a worthy successor to the PlayStation Vita.
As you delve into the video, it’s clear that this Portable PlayStation 4 isn’t your average mod project. Instead of opting for more commonly modded devices like the Nintendo GameCube or Wii, Restore Technique chose the more powerful PlayStation 4 Slim. This choice reflects an ambitious leap, as the PS4 and comparable PC hardware from that time can still deliver impressive gaming experiences. Moreover, the PS4 Slim’s low-power design was a strategic choice, helping to maintain an ideal heat and power balance necessary for a handheld console of this nature.
In terms of execution, Restore Technique meticulously selected a PlayStation 4 model that required less power, resulting in a smaller PCB. By expertly removing unnecessary ports and components, using top-notch soldering tools, and reducing the aluminum heat spreader with a Dremel, he successfully shrunk the system down to size. He even incorporated a fan controller to keep the device cool, though he acknowledges the possibility of overheating.
The handheld also includes the integration of a DualShock controller, wired intricately from various test points to new spots within the device. Powering this creation is a custom-made 3S2P LiPo 12V 10,000 mAh battery pack, rechargeable through an upgraded 10 Amp DC power jack, allowing simultaneous gaming and charging. To manage the power outputs, DC buck converters were used to adjust the necessary voltages for both 12V and 5V rails, accommodating the screen’s lower voltage demands.
In the video, Restore Technique shares gaming footage, notably playing The Last of Us for 86 minutes, highlighting the handheld’s preference for being near a charger. He also notes that due to the high wattage of the battery, this console may face restrictions on most airlines.
The video goes beyond just modifying the PlayStation 4 Slim motherboard. It delves into a multi-step prototyping process for the “PS4T” shell, which started with FDM 3D printing but finalized with resin shell manufacturing by PCBWay for its superior heat resistance.
During initial tests, the PS4T encountered some thermal and power issues, leading to visual glitches and game slowdowns. However, after replacing the controller frames and enhancing internal electrical shielding and heat management, the handheld began to operate smoothly without graphical errors.
This ambitious build is not just a testament to technical prowess; it’s a tribute to the maker ethos of learning through trial and error. It’s an inspiring project to watch for anyone interested in electronics, 3D printing, and DIY innovation.
