Thank you for your suggestions wyoelk, i am trying to solve a problem for a friend. In his situation there is no pulsed signal to use as a trigger for the 555. When power is applied the output should be active for say 2 minutes and then switch off, until the power gets disconnected (which might take hours) and reconnected again.
