Hi
I wanted a circuit with a timer controlling an output preamp relay. A LED should blinking meanwhile and stay ON when the relay
get closed.
I designed this one with RL3 reseting U4. Q41 also starts RL2 the output relay.
It works but after a while, D7 restart blinking. Maybe there is not enough current for 2 relays.
How can I fix this ?
Mainly, is there a more clever way to achieve the goal ?
