The candle, danger removed.
A perfectly good computer.
Under the flame sits an ESP32-S3 with Wi-Fi and Bluetooth LE, driving 144 lights you can address one at a time. Create unique applications and explore edge computing with open source tools optimized for agentic development.
It thinks.
A tiny neural network was trained on recorded candle footage to describe its flame behavior with eight variables.
