Maker Builds Invisible 3D Air Drumkit
On April 1, 2026, maker Arpan Mondal unveiled "Space Drums," a pair of ESP32-S3–powered drumsticks that create an invisible 3D drum kit using onboard IMUs and a smartphone-fed pose-estimation model. Mondal combined accelerometer/gyroscope data with cloud-based posture tracking to eliminate IMU drift, mapped hi-hat, snare, toms, cymbals and a shoe-mounted kick, and published instructions and Apache 2.0 source code on Instructables and GitHub.
Scoring Rationale
Timely maker project with actionable open-source code, strong for hands-on practitioners. Scored for high actionability and clear relevance to embedded/vision makers, but limited novelty and narrow scope, and based on a single-source project write-up.
