Description

Background of the project: Fidget spinners are very popular recently. I can see many people playing anytime and anywhere. Especially my little nephew. He took it almost everywhere. I am really curious as to why it is addictive. Besides, I’ve noticed that there are most kinds of fidget spinners on the market are made of iron and they all have sharp edges, which are actually dangerous for children. So as a PCB manufacture, we plan to make a homemade fidget spinner with LED lights. I plan to use plastic shells and make them round so they will be safer. Interesting stories related to the project: I prepared 5 sets of PCBs and components for the first time. I place the PCB order on ALLPCB and  bought all required components from website. When I assembled all these components in the office, my colleagues around me showed great interest. After I finished the assembly and went to the bathroom, my finished product was taken by my colleagues to play with, and they quickly became addicted. In the end, the 4 sets that had not been assembled were also taken away by them. It seems that I need to place more orders, otherwise my little nephew will never get his fidget spinner. My experience with ALLPCB: Without prior notice, I pretended to be a customer and used the free prototype coupon to experience the whole process of placing an order, putting it into production, and receiving the products on the ALLPCB website. The production speed and delivery speed of the factory are really fast, as always. (It has to be fast because we’re in the same city, lol) They will definitely wonder why the shipping address is so close this time, haha.
