The student designed a comparator and isolation circuit printed circuit board using Altium designer 10. They switched from a switching power supply to a transformer power supply due to voltage ripple issues. For next week, the student plans to design printed circuit boards for all remaining circuits in the project. The strong point is PCB design skills, and the weak point is the large size of the power supply.

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.

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 designPCB of all circuits.
