Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects. With the Arduino UNO board and the Arduino program code, we can make a controller for our project. In the practical session, my group and I programmed the Arduino UNO board to control the servo to make the pegasus's wing flap. Beyond the base requirement, we decide to use the push button to control the start of the flapping. To make our pegasus toy more interesting, we added a melody using the Arduino programming. The melody we chose is the State Anthem of the Soviet Union🐻. Working Principle We use the metal wire to connect the servo and the pegasus's wings. When we program the servo movement, the servo will be turned and apply force to the wing. Thus the wings will be flapping.  Programming To achieve this, we  combined 3 individual codes together: the push button, the melody, and the servo. So we write the code one by one for e...

Laser Cutting Laser cutting is a process in which a high-power laser is used to cut through materials. In this process, a high-density beam is created by stimulating lasing material with an electrical discharge, within an enclosed container. Optics are used to focus the created laser beam onto the workpiece, effectively cutting it by melting, vaporizing, to burning through it. The laser cutter that is used in our school FAB lab is the CO2 laser cutter. T here are two options for the laser cutter, vector and engrave.  Vector means to cut through the material and engrave is cut the patterns on the surface of the material.  In the SP fab lab, I got a chance to operate this CO2 laser cutter.  but before I start the laser cutting machine. Safety is the most important thing that needs to be considered. Thus, when we want to use the laser cutter, we need to be well prepared and develop a standard  operation procedure (SOP) EPILOG PRO LASER CUTTER  SOP Pu...
