Rob,
By someday, do you mean this century? LOL
I know the feeling, I have too many unfinished projects that
I will finish someday too.
One of them is a temperature controlled toaster oven to reflow SMT.
I have the degutted toaster oven laying around, I have the SSR relays also
I just need to install the thermocouples and the Microcontroller.
Someday, I will finish it too.
Meanwhile, I am getting ready to fly to my son’s home for the holidays.
Merry Christmas to the whole group.
