I need help to a simple electronic circuit.
I need an red LED to "flash" kind of like the white standby lamp on a Mac computer.
Slowly up and down. Not just on and off... It need to run over a capacitor for five to ten minutes after the power is off. And the power supply is 230V AC.
Can it be done very simple with a few components. ?
... a digital circuit, a diode, a capacitor or two, a pair of resistors and a red LED and .?
