Light evolving lamp

pinshape

This is an experimental lamp designed to showcase unique shadow/light reflections on a wall by utilizing various objects placed atop its rotating platform. The platform itself is crafted from semitransparent PET-G and features two LED strips, repurposed from cheap "usb led lamps," as seen in the attached picture. The focus of this project lies in manipulating shadows and reflections on the wall behind it. By placing different shaped objects on top of the lamp, users can create diverse shadow effects. The rotating platform has three holes at its top, which allows for further manipulation of these effects by enabling the movement of reflections. A key feature of this lamp is its ability to rotate, facilitated by an Arduino Nano and a 28BYJ-48 stepper motor. Standard bearings with a diameter of 22mm x 7mm and an 8mm hole are used, with a spacer placed between them for added support. These bearings were previously stored in the fridge before being mounted. Capturing these unique effects through photography can be challenging, which is why the provided pictures may not fully do justice to the lamp's capabilities. For those interested in experimenting with this project, a simple Arduino script and the StepperMotor.h library are included. This script serves as an initial testing ground, but it is also designed for beginners who lack experience with Arduino. The script emphasizes the importance of killing power to the motor after every move to prevent overheating of the plastic. The Arduino and stepper motor operate off a 9V adapter, while the two LED strips are powered by an old 5V adapter. However, users can opt to power everything from a single 5V adapter if preferred. This setup allows for flexibility in terms of light source selection, provided it fits within the lamp's parameters.
