The weekly report summarizes the progress of student Thanaphon Yeamkam and his group on their multi-disciplinary workshop project. This week, Thanaphon designed a comparator and isolation circuit printed circuit board using surface mount devices to minimize the circuit size. He had issues with the initial switching power supply design due to voltage ripple, so switched to a transformer design for a more stable power supply. Next week, he plans to design printed circuit boards for all remaining circuits.

Weekly Progress
I was responsible to design the Power Supply circuit. And design all
PCB in the project. I used a switching power supply is not working. Because the
the voltage have ripple. So I have switched to the transformer. Because
the transformer power supply is stable.
And this week I designed a PCB of comparator and isolate by using
the Altium designer 10. I designed the circuit using SMD in some devices. To get
thell circuits. is smaller.
Comparator & Isolate Circuit
Engineering Analysis
Strong Point
I can design a PCB by using the designer 10.
Week Point
the power supply is large and can not find a way to install.
Next Week Job
I will design PCB of all circuits.
