An autonomous flame-shaped lamp/nightlight controlled by microcontroller with WS2812B LED ring and integrated Qi wireless charging.

Status : Hardware validated ✅ - Firmware development in progress
Last update : September 2025

• Autonomy : 2-3 hours on LiPo battery (320 mAh)
• LED Patterns : Heartbeat, chase, fade, realistic flame effects
• Control : SW-18030 shock detector for interaction
• Charging : Qi wireless + automatic power-path management
• Waterproof : No USB port, induction charging only
