besides I have several LM324's on hand that I want to use.
have similar project using same LM342 (had 20 units given to me)
hi
You could use a couple of diodes and resistor to make an OR gate to replace the logic ic.
Looks like he used two NAND gates to make an AND gate, not a OR gate, both inputs need to be logic 1, or did I miss something?

Ok, so three diodes then![]()

Sorry Eric, no offense to you, you did say or gate. Not to negate your input. My apologies.![]()
I was under the assumption that both inputs must be true, else relay is off. Actually after re-reading OP I wonder if he wants XOR function? I did not mean to offend, often forum communication creates misinterpretation.
in order for relay to energize
hope I got this right??
Why do you think you are offending me.
Like you I dont not know for sure what the OP wants to do.
I assumed that the mention of two diodes would start bells ringing in MrDebs head, as a possible solution.
it works in simulation
