I built the world's smallest fully playable game controller.
It’s only 42.4mm wide.
This video covers the complete workflow, including 3D printing, CNC machining, PCB design, micro-joystick development, final assembly, and real gameplay tests on Steam Deck and PC.

I'm MEAKYI, a DIY enthusiast from China. One day, a spontaneous idea sparked after dinner: "Could I build the world's smallest functional game controller?"
This project took about 5 months to complete.
Besides building the controller itself, the process also included filming the entire project, video editing, and some 3D animation rendering.
Since I’m not a professional engineer, many parts of this project were my first attempt. A lot of time went into experimentation and feasibility testing.

Compared with Xbox Wireless Controller
Reference device: Xbox Wireless Controller (Model 1914)
To achieve the miniature size, the controller keeps the core gameplay features:
Full button layout
Dual clickable joysticks
Analog triggers
Main vibration feedback
Due to internal space limitations, the following non-essential features were removed:
Impulse Trigger Rumble
Accessory expansion port
3.5mm audio jack

我是 MEAKYI，一名 DIY 爱好者。某天饭后突然有了一个想法：
制作一款 世界上最小、但依然拥有核心游戏功能的微型游戏手柄。
整个项目断断续续花了大约 5 个月。
除了手柄本身的设计与制作，还包括全过程拍摄、剪辑，以及部分 3D 动画渲染。
由于我并非专业工程师，视频中的很多内容对我来说都是第一次尝试，因此在可行性验证和调试上花费了大量时间。
