Don't Buy a $150 Space Mouse. Build This for $10
Why spend $150 on a 3D mouse when you can build a better one for under $10? 🛠️💰
In this video, I show you how I designed and built the Ultimate DIY Macro Pad and Space Mouse using a Raspberry Pi Pico. This isn't just a keypad—it’s a complete productivity station for Fusion 360, Blender, and coding.
It features a custom 5x5 mechanical key matrix, two rotary encoders for scrolling and volume, and a custom-built 6-DOF Space Mouse (magnetometer-based) that lets you orbit, pan, and zoom in 3D space effortlessly.
I also programmed dedicated "finger-saving" macros for Select All, Cut, Copy, and Paste to speed up my coding workflow.
