Ultra-low-cost robotic joint: a $1.5 FOC board inside a 1503 gimbal motor, plus a 3D-printed high-ratio precision gearbox. Cheap power, exact motion.
Open-source vacuum robot cleaner
Handheld Raspberry Pi flight tracker for a young plane-spotter: live map, plane photos and routes, a logbook, ADS-B antenna fallback and a 3D-printed case
PAROL6: open-source 3D-printed 6-axis desktop robot arm. BOM, STL and STEP files, firmware and build instructions.
MOSS: a small, mostly 3D-printed litter-picking rover. Cleaner streets, one maker at a time.
Raspberry Pi 5 home NAS: CasaOS apps, Nur Hub and the Nur app (local AI, Fish Audio voice), a 3D-printed case and an ESP32-S3 touch screen
Open, minimal sEMG wristband like the Meta Neural Band: 8-ch ADS1298 + nRF52832 BLE, dry gold electrodes on a flex, 3D-printed band. KiCad, FreeCAD, Zephyr, Python, simulations.
Faze4: open-source 3D-printed 6-axis robot arm with cycloidal gearboxes and the wiring inside the arm, the files to build it.
A compact linear motion base built primarily from 3D-printed parts and PETG linear rails.
A hand-wired, 3D-printed ESP32-S3 macropad that mimics the Codex Micro - built in a weekend. Yes, it has RGB.
