I am new to this group, and never thought about making my own PCB's.
I have usually ordered them, but I see the benefit and am curious
about this.
Now on this thread...It would seem to me that you could modify a
George Foreman grill to use flat plates instead of the ribbed ones
and limit the heat and whammo a simple small double sided hotplate.
Am I completely wrong on this? If not, I might look into it as I
have a couple laying around. And even so, they are only like 20
bucks for the small one.
