The author built a pair of custom invisible wireless earphones by completely modifying a pair of wireless earbuds. One earphone was molded to fit inside the ear using silicone and clear resin, while the second was miniaturized and built into a pen as a tiny wireless microphone. The original electronics, touch controls, and charging case were modified to fit the new designs. The project combines reverse engineering, electronics miniaturization, soldering, custom ear molding, resin casting, and precision assembly.

This open-source drone uses a single motor and a hinged propeller to control pitch and roll, reducing mechanical complexity while relying on sophisticated software.
Features of the project:
The project combines 3D-printed mechanical components, real-time control systems, and custom electronics to demonstrate a compact, unconventional drone design. Its simplified mechanics could enable cheaper, smaller, and easier-to-manufacture drones.
