Light evolving lamp This is an experimental lamp designed to create unique shadow/light reflections on the wall by placing different objects on top of it. The effect is amplified when these objects are positioned in creative ways. The lamp features a rotating platform made from semitransparent PET-G, allowing for maximum visibility and flexibility. Inside this platform lie two LED strips extracted from cheap "usb led lamps", which provide ample lighting for the shadows to take shape. By manipulating different shapes on top of the lamp, users can alter and enhance the reflections and shadows projected onto the wall behind it. The rotating platform also comes equipped with three holes in its top, enabling the reflections to move and transform as it spins. Control over the rotation is achieved through an Arduino Nano paired with a 28BYJ-48 stepper motor. The bearings used are standard 22mm diameter x 7mm with an 8mm hole, which have been pre-chilled in the fridge for optimal performance. Capturing these dynamic effects can be challenging, making it difficult to accurately convey their impact through photographs alone. To better illustrate the lamp's capabilities, a short video has been created (though speeded up) that demonstrates its potential. An accompanying Arduino script and StepperMotor.h library are provided for users to experiment with different movements and settings. It is essential to note that the motor must be powered off after each move to prevent overheating, which could cause damage to the plastic components. Powering the lamp requires a 9 V adapter for the Arduino and stepper motor, while the two LED strips can run on an old 5 V adapter. Alternatively, all components can be powered from a single 5V adapter if desired.
