Jeezus...this is getting sophisticated! Definitely over my head, skill-wise...
Is there a voltage regulator on there too? I don't need that...I plan on using a 7805 seperately before it even gets to the circuit...
I marvel at your skills here, but I think this might be overkill?
I don't need an electronic pulse, per se, designed into this...
Yes, the relay itself needs a pulse to latch, but I can make do with a steady output as long as the switch is held. Once released, then no more output...this is perfectly fine, and simplier.
As for the output itself, all I need is just a + lead coming off the circuit...
I don't understand how the relay is integrated in your design here...
There is a LOT going on here I don't understand...
Isn't that design #3 sufficient for my purposes, minus the vreg?
I can take just a + output, run it to the + side of the latch, and run the same + lead into a grounded relay, to send a ground pulse to the latch at the same time...wouldn't that be easier? I can't have it constantly grounded, because of the polarity swap needed for unlatching...
As far as unlatching, I have another switch setup for this...which just applies opposite polarity to the relay to unlatch it...
Here is a pic of the parts...
