## Summary

A user proposed an external head-mounted micro-drone companion concept, worn via a headband, hat, or frame, to avoid the surgical risks and approvals of brain-computer interface implants. The design uses ducted fans with safety mesh guards to protect hair, ears, and skin, and relies on proximity sensors and gyroscopes combined with AI to achieve stable hovering that moves with the head; control is via a small remote-control pad or surface neural/gesture signals. The poster asked the community about engineering and safety challenges such as battery weight, noise near the ears, and wind-disturbance stability.
