Arduino Transforms Lego Into Alarm
A maker used an Arduino to turn the Lego NASA Artemis SLS set into a functional alarm clock, combining creative repurposing with electronics for a desk piece that blends nostalgia and utility. The project demonstrates how DIYers are integrating microcontrollers into everyday objects. Another Arduino project created a Smart Anti-Kickback System for electric drills using an IMU sensor to detect risky movements and prevent accidents.
- The Lego NASA Artemis Space Launch System set (10341) used in the alarm clock project is a 3,601-piece model standing over 27.5 inches (70 cm) tall and is designed for adults. - The alarm clock modification uses a stepper motor to raise the rocket for the "launch" and plays rocket sounds through a hacked megaphone instead of a typical buzzer. - It is powered by an Arduino Uno R4 WiFi, a board that features a 32-bit Arm processor, which is a significant upgrade from the 8-bit processors in earlier models, and includes a built-in 12x8 LED matrix. - The Smart Anti-Kickback System addresses the dangerous phenomenon where a drill suddenly jams and transfers torque back to the user, which can cause serious injury. - The safety system was built by MohammadReza Sharifi using an Arduino Nano 33 BLE Sense board. - Instead of monitoring electrical changes, the anti-kickback system uses the Arduino's onboard Inertial Measurement Unit (IMU) to analyze the drill's physical motion, detecting the specific signature of a kickback event like sudden angular acceleration and instability. - An IMU is a sensor that combines an accelerometer and gyroscope to measure an object's orientation, velocity, and rotational movement across three axes: pitch, roll, and yaw.
