Unfortunately, my design didn’t work at last. The main reason for the LED failing to light up may be the wiring, which I lacked time to recheck, or that the battery ran out of power. This is also a part that I will need to improve on, which is the design and application of circuits. Another thing that I would need to improve on is the choice of materials. Due to the fragility of the wires, tissue paper, and the LED light is more challenging than I thought it would be to work with them. The tissue paper was torn several times accidentally through the process, and the wires which acted as the framework of the dress were bendier than I needed them to be. In addition, I also broke one LED when I was working with the circuit. However, I really like my design and think it is both original and creative. It’s quite a pity that I cannot create it as planned, and the top layer of the dress remained undone. Another success of my design was the pedestal. Since I chose to make it out of cardboard, I can still create holes through the surface easily to stabilize the LED and the switch, which also made the process of creating the circuit relatively simple. Overall I chose these materials because they are eco-friendly. The tissue paper, steel wires, and cardboard are all made of natural components and easy to recycle. The design for transforming energy is quite simple and was kept comparatively sustainable since it didn’t require much equipment changing except for the battery. Overall, I believe that my design will make a good toy and decoration for kids in the dark if it is working, for it being both safe and pretty.
