This weekly report from an engineering workshop group describes their progress on developing an air purifier. The group, called 361 degrees, is divided into an engineering team and product design team. This week they have made progress combining all the purifier's modes into a single circuit. Their next steps are to finish the circuit board and ensure all functions work normally. The report includes figures of modules used and notes on engineering knowledge gained about components like the MP3 module, power amplifier, and SD card.

Weekly Progress
The concept of group: The machine is used then relax and to feel comfortable.
Overview: The appliance is equipped with a power supply, amplifier,right circuit and controller in
the each section. There will be modal to determine the difference. This air purifier on the mode 4
modes. In each mode, it will keep working on the machine.
Knowledge of Engineering :We will extract data from a memory card and Need to know the
functions and applications of the device with me. For example,Memory card is connected to the
connector pin is on the increase and where it will be leased, Students learn about the
characteristics and Property of a MP3 module, power amplifier and sd card.

Engineering Analysis
Strong Point
There has been much progress in this section are in the process of combining all modes of the circuit
together.
Week Point
In this section, I do not have the strength and my colleagues to communicate not clearly. But now I
have come to understand more than ever.
Next Week Job
When all the functions work normally. From then, it will be the only section on PCB.
