Digital Candle Computes Its Flame Live on an ESP32-S3 Microcontroller

Kevin Bates's Digital Candle generates its flame live on an ESP32-S3 microcontroller, a single-chip computer, running a small neural network trained on footage of a real candle. The 10-inch desk object drives 144 amber LEDs in a 9-by-16 grid, producing a flame that never repeats, according to The Verge. It costs $149.
