This weekly report summarizes the progress of the Habit Thai company engineering team. This week, the team learned basic PCB design using Altium software. They also discussed their ventilation product idea, researching wind properties and ventilation. Their main concept is to "make a good feeling" through ventilation. However, they realized a one-way ventilation system would not work and that good ventilation requires air flow in two directions. Next week, the team will share data about ventilation.
