Nattawat Boonmee reports on his group's progress designing a water heater circuit. This week, they designed and built a finished PCB circuit with segments that were all tested to function properly. Nattawat was responsible for the microcontroller interface and LED driver, which were found to work together with the circuit. The group connected the electronic components to the water heater designed by the Product Design team. Initial testing showed the water could be heated to 40 degrees Celsius. Next week, Nattawat will record performance tests to document in a report.

Weekly Progress
Part of My responsibility My project is Water Heater, This week we have designed and built the
finished PCB. The circuit was built has been added to check the function of each segment. We
found that all the test circuit in each segment can be run as needed. It is the responsibility of the
MCU interface and LED Driver. I was responsible for most of the interface microcontroller and LED
Driver. Circuit found that the two can work together. Then we contacted the Product Design Team
to various electronic equipment to the water heater. To the circuit in the right position. Once right
position, we will install a circuit and wiring to make a tidy and safe. When we put the circuit wiring
from the Product Design Products have been tested to work again. The water can be heated by the
heat from normal water temperatures reach 40 degrees Celsius in the past. Circuit can work well
together, whether the water level or the level of the heat.

Engineering Analysis
Strong Point
- The circuit Circuit can work together. All sectors.
- PCB circuit size is small.
Week Point
- Although the circuit can perform as expected. But we do not have time to test the long term. To
check the stability of the circuit.
-Not sure of the compatibility with the Product Design object.
Next Week Job
-Next week, I will recorded the performance to be documented report.
