Dear Experts,
I am thinking of making a capacitor auto-charge-discharge circuit.
Not sure if this is ok :
Idea :
1. hook-up a voltage comparator to the capacitor receiving charge.
2. the other voltage comparator input pin connects to ground.
3. make the comparator output a signal only when capacitor reaches 5v.
4. when voltage comparator outputs a signal, it triggers a transistor switch that makes the opens the circuit on the wire from the power source to the capacitor +ve connector. So, capacitor will discharge through a short that is turned on when transistor is triggered.
However, I am not very sure how the transistor should be used to open the circuit and close the circuit for discharge.
Please let me know how you think about this method.
Have a great day.
Best regards
Pascal
