Attached is a circuit I created to display the intensity of vibration of a machine using a output of a piazzo device

although the circuit works fine, you can notice some flicker in the LEDs and brightness variations.

I prepared the below peak detector hoping that would sort the issue but with no luck.

dose any one have simpler peak detector that i can use with this, ideally a one that would work with 3.6V?
