do you need Latching type circuit.just brief your requiremnt

 

[Usama Siddiqui]

yes latching type could be used,basically i wanna trigger the circuit as a roller turns the motor,but the prob is that it does not keeps on generating energy untill the roller is being turned,i don wana use flywheel technology,what i wished to search was just a triggering circuit that once triggered could produce self sustainable energy to the circuit for the maximum period that it could withhold .
