Hmm... are you talking about fig. 3 on this page? http://sound.westhost.com/project39.htm

Yes, it's an pretty standard circuit -- you set the charge/discharge time with a couple of resistors and one cap -- the discharge transistor should be able to handle the current that will flow as the gate is discharged -- i used a little D-Pack HexFET for the relay control -- nice for perfboad.

I agree with Rod Elliott. If you want to use that circuit, use a separate supply. Unless you have a resistor that will surely survive the overload.
