Hey, I was just thinking about a playset that changes its lights when someone waves their hand—like a robot that reacts to touch. What if we build a mini LIDAR inside to detect motion? I could add a little robot arm that reaches out, but we'd need to keep the circuitry small.

Sounds like you need a compact 2D LIDAR module, probably a time‑of‑flight one, and a microcontroller that can read the packets in real time. Make sure the packet loss rate stays under 1 % otherwise the arm will jitter. Use a small servo that has an off‑the‑shelf 12 V rating so you can keep the PCB tight. Remember to tag the power supply with a tracker if you lose it. The key is to log every frame and fit a simple Kalman filter to smooth the hand‑wave data. Good luck!
