Thanks Len
Any way to squeeze a variable pod in to be able to adjust the time?
R1 & C1 provide a delay. If R1 = 1M, then the approximate delay is = C1 in uF, eg. if C1 = 4.7 uF, then the delay will be somewhere in the 3 ~ 6 second range. Altenartively, if you make R1 = 10M, then 0.47 uF will give you the same delay.
See when I crank my car the dc-dc converter is not supplying enough power to the laptop while the car battery is under crank load. Yet there’s enough power for the switch/pulse to be sent thus the laptop doesn’t see it. I need to be able to delay it and adjust the delay.
So I crank the car 12v is sent to the switch and the timer kicks in and counts down to X amount of time adjusted by a pod and then pulse is sent.
Or am I missing something on your schematics that already accomplishes this?
Thanks
