Vorapol chaoroenkitwasin is a student in group 1 working on an engineering project. This week, the group had issues with communication that caused delays. Specifically, they were unsure whether to use a 5V or 9V power supply across their 4 circuits. The professor recommended standardizing at 5V for easier design. Vorapol and Top agreed this was preferable to using a 9V transformer. Vorapol's task this week was circuit design on paper, including capacitor value calculations. The group aims to produce a printed circuit board next week.

Weekly Progress
I am group 1. Yesterday my group has problems are don’t have communicate in my group. I do in
part power supply. My group has 4 circuits and problem is use voltage 5 V in 3 circuit and use
voltage 9 V in 1 circuit. Professor gave we calculate current and power in all part by fixed Voltage at
5V. For me and Top do in part power supply easier. Because all circuit use voltage 9 V will must use
transformer 9 Volt 1 Ampair, but if use transformer 5 Volt will easy and use little area. This week
my part has circuit in paper, but has calculate capacitor value.
Engineering Analysis
Strong Point
- Project have nice design.
Week Point
- We don’t have communicate in group. Cause project slowly.
Next Week Job
My group will have print circuit board.
