Hi all,
I'm trying to build a single power supply op amp based one shot.
I'm interfacing to a accelerometer which has a 10mv/g ac wave riding on a 12 dc bias.
I've used a single op amp from a quad package op amp to amplify the signal and now I would like to use that to light an LED.
Since the accelerometer requires 27 volts, I'm using three 9v batteries for power for both the accel and the op amp.
The pulse I'm getting is too narrow to see easily on the LED so I'd like to trigger a pulse from the one shot and use that to keep the LED lit longer.
The input will be a small ac pulse. i would like to extend the pulse to about a second.
Any suggestions?
Thanks
Dave
