I need a compact, three-axis gimbal designed specifically to keep a Raspberry Pi camera rock-steady while I capture video footage. The core objective is clean video stabilisation, not fancy tracking or scripted pans, so the system only has to respond to direct manual input (a thumb-stick, potentiometers, or other simple interface you recommend). Structure & materials – The frame should be plastic so I can 3D-print the parts in-house. Please balance strength and weight so small hobby-grade brushless or servo motors can move it smoothly. If a tiny metal insert or bearing is unavoidable for durability, note that in the BOM. Control electronics – Everything must run from a Raspberry Pi (any recent model). – Manual control: propose the most reliable way to feed joystick signals into the Pi (GPIO, USB, I²C, etc.) and map them to the three axes. – I am comfortable installing libraries, but supply the Python (or C) control script ready to run, with comments that make it easy to tweak PID values later. What I’d like from you 1. Mechanical design files (STL + editable source, e.g., Fusion 360 or SolidWorks). 2. Motor sizing calculations and part numbers for readily available motors, drivers, bearings, and fasteners. 3. Wiring diagram showing Pi, motor drivers, power rail, and control interface. 4. The control script plus a short README outlining setup and calibration. 5. A brief test video or screenshots proving all three axes stabilise correctly under manual command. The project is considered complete when I can print the parts, follow your guide, and replicate the stabilised output on my bench.
