Turn your lights on and off by staring at this little robotic switch
Reading Time: 2 minutesUnlike every other hands-free light switch that relies on infrared motion detection or changes in ambient light values, Michael Rigsby’s “Look at Me Light Switch” instead requires a person to stare at it for six seconds. Based on an embedded machine learning model and a microcontroller, this device uses Person Sensor from Useful Sensors,…

3D-printed continuous rotation servo motor is super smooth
Reading Time: 2 minutesThere are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement. DC motors work well for high speed movement that doesn’t need any rotational accuracy.…
