Weekly Progress
This week I make pcb and change some circuit from on PCB to versatile bord. That is
comparator temperature circuit because it fails both performance and size. In part make pcb I
use altium program make pcb 2 two face so I used dryfilm and caustic by myself. I and
members in group cooperate install all circuit and lm35 in kettle involve change transformer is
center tap 9v 0 9v 800 mA which transformer older current not enough and calculate some
values success
Figure.1 comparator temperature circuit Figure.2 install lm35
Engineering Analysis
