Ok, I know, my first post was sort of incomplete.
So I revised it a bit to see if anyone, as to get another opinion, can go over the schematic, and see if anything is wrong with it.
I build my own electronic circuits ect.. and program microchips, but this is my first
time trying to isolate the parallel port of a PC, with opto electronics.
I just need someone to confirm that everything is OK, before I purchase the parts for this.
The inputs are low voltage and only require resistors to isolate.
The outputs, are to control relays ect... and need to be isolated.
In this schematic, you'll quickly see which is which.
Thanks in advance. My first post had no replies, which leads me to beleive, no one is interested.
