Step 1: Parts

9 volt battery led and a capacitor

Step 3: Done

Power it up and remove one of the battery wires and it will fade off
<p>I think this needs more detailed instruction</p>
<p>ok, so does this get wired in parallel?</p>
<p>the capacitor and the led</p>
<p>9 volts may kill most LED's instantly! Use a current resistor for .20 ma at the LED voltage. </p><p>Resistance = Vin - Vled / .02</p><p>Red and yellow LED's need only 1.5 to 2 volts. Bright LED's can use up to 3 volts.</p>
one step short of a flashlight. a &quot;breathe&quot; effect would be more useful.
