This weekly report summarizes the progress of a student group working on an engineering project. They designed a touch circuit board for an electronic kettle and installed copper panels on the side of the kettle body. The touch panels are located inside the kettle body to avoid interference from boiling water. The circuit uses a 7404 IC to trigger functions from touch inputs. Going forward, the group needs to finish their work on the project.

Weekly Progress
Make new PCB for touch circuit and connect electronic device on PCB, edit problem
unstable inside system touch by circuit touch leave main circuit and use one wire input one
touch one function(We use 3 function) and use IC 7404 help trig form output function.I’m
install copper for touch beside body kettle.I can’t touch panel in front of body because boby
boilling water has big side affect little area and concern temperature Interference work. I’m
choose install touch panel inside body because has space more in front of body and hold
for give wire.

Engineering Analysis
Strong Point
PCB circuit touch panel leave main PCB because protect noise form main circuit and
problem voltage and current ,can repair easy when you need.
Week Point
PCB has small side and IC touch panel subtle ,when repair circuit copper off easy from
PCB.
Next Week Job
Finish working.
