YouTuber Restore Technique has shared an impressive and detailed 27-minute video showcasing his self-designed PlayStation 4 portable project. This ambitious project involved creating a truly handheld PlayStation 4 using a specially 3D-printed casing, customized PCBs, a 7-inch display, and the original motherboard from a PlayStation 4 Slim. The result is a device measuring 249 x 156 x 49.2mm and weighing 1.7kg, which some might argue is a worthy successor to the PlayStation Vita, especially when compared to the PlayStation Portal that focuses solely on streaming.
As you delve deeper into Restore Technique’s video, he elaborates on how this project stands out among similar handheld console modifications. Unlike the usual mods that utilize Nintendo consoles like the GameCube or Wii, this one employs the much more powerful PlayStation 4, which can still handle a variety of games from the same era. Interestingly, the PS4 Slim’s low-power design made it an ideal choice for achieving the desired balance of temperature and power in this handheld makeover.
The meticulous process Restore Technique employed is fascinating. He opted for a PS4 model with a reduced power consumption, which inherently featured a smaller PCB. This meant some ports and components had to be carefully removed, employing quality soldering tools and even a Dremel for reshaping the aluminum heat spreader, which cools the main components. He also added a fan controller to enhance the cooling by pushing the fan beyond its standard speed; though he did mention the potential risk of overheating.
Incorporating a DualShock controller was no small feat either. It required numerous wires to be rerouted from various test points on the controller to new positions throughout the device. Given the demands of a portable system, Restore Technique crafted a custom 3S2P LiPo 12V 10,000 mAh battery pack, charged through an upgraded 10 Amp DC power jack, allowing gaming while charging. He also used DC buck converters to manage varied voltage needs, considering the screen runs on a lower voltage and could be damaged by excessive power.
Within the video, Restore Technique shows footage of gaming on the handheld, playing The Last of Us for 86 minutes, which suggests that this system operates best when plugged in. He notes that the high wattage of the battery setup makes it unsuitable for air travel on many airlines.
The video provides insight into the extraction process of the PS4 Slim motherboard and a thorough explanation of prototyping the PS4T shell (short for PlayStation 4 Transport, it seems). The prototype utilized FDM 3D printing before transitioning to a more durable resin shell from PCBWay to better withstand the heat generated by the device.
Initially, the PS4T faced thermal and power issues that led to graphical glitches and slow performance in several games. However, after frame replacements and enhancements in electrical shielding and heat management, the handheld started to perform reliably, free from graphical errors.
This project is a remarkable achievement, blending electronics, 3D printing, soldering, and embodying a maker spirit that thrives on learning through trial and error. It’s a must-see for those interested in the intersection of gaming technology and creativity.
