1) This weekly report summarizes the progress of a student named Mr. Chanwut Sanpetvessakul on his product design project to build a kettle. 2) This week, he worked on the control phase circuit to control the power for the hot coil and tested the circuit, which was able to use a real coil. 3) He documented his project including all circuits and gained knowledge about processing each circuit in his project. His challenge was making the circuit compatible with the coil, but he was able to modify it for compatibility.

Weekly Progress
Overall : This week. I work circuits about My project ”kettle”.In project I have work “Control Phase”
Circuit by Process Circuit to control phase power for hot coil. I can Modify compatibility coil(TOSHIBA
Figure 2) and “Control Phase” Circuit. I can test Circuit finished. It can use real and know Process Circuit. I
Do Documents Project ”kettle” include information all circuit as power supply 12V Circuit, sensor Circuit,
Button Circuit, select Circuit, comparator Circuit, Op-to Isolate Circuit.
Enginerring knowledge : This week I have been looking for information about “Triac“ and “Op-to Isolate”
to design circuit “Control Phase” and know Characteristics “Triac“ and “Op-to Isolate” standard from
Datasheet. I Do Documents Project ”kettle”. I get knowledge about process all Circuit in my project. And
I can Modify compatibility coil(TOSHIBA Figure 2) and “Control Phase” Circuit.
My problem : circuit degin Incongruous coil.I must think to Compatibility.

Engineering Analysis
Strong Point
I know Characteristics “Triac“ and “Op-to Isolate” to design “Control Phase” Circuit. I can Modify
compatibility coil and “Control Phase” circuit. I can test Circuit finished. It can use real.
Week Point
circuit degin Incongruous coil.but I can Modify compatibility.
Next Week Job
Next week.I will finished project work and paper project.
