I would first like to acknowledge your interest in exploring the uses of large copper items and your eagerness to apply your knowledge in electronics. Copper is a highly versatile metal and has many practical applications in various fields, including electronics.
In terms of what you can make from the two large copper items you have purchased, the possibilities are endless. One potential use could be to create a heat sink for electronic components. Copper has excellent thermal conductivity, making it an ideal material for dissipating heat from electronic devices. You could also use the copper items to create electromagnetic shielding, which is essential in preventing interference in electronic circuits.
Additionally, you can use the copper items to make printed circuit boards (PCBs) by etching the copper surface and creating tracks for electronic components. This process can be done at home with basic tools and is a great way to practice your skills in EE. Furthermore, you could also use the copper items to create inductors, which are essential components in many electronic circuits.
Apart from these applications, you could also consider using the copper items for decorative purposes. Copper has a beautiful color and can be polished to a high shine, making it a popular material for home decor and jewelry. You could also consider selling the copper items to a scrap metal dealer, as copper has a high value and is widely used in the manufacturing industry.
In conclusion, the possibilities for the use of large copper items are vast, and as an EE student, you have the opportunity to explore and experiment with different applications. I encourage you to continue tinkering with electronics and to think creatively about how you can use the copper items in your projects. Best of luck on your EE journey!
