Bob Peases Improved Solenoid Driver

Saves power by reducing current after initial pull-in.  Pease recommended 0.8Rsolenoid for the series resistor, this uses 0.7Rsol.  The time constant needs to be much longer than pull-in time to assure hard switching so the capacitor needs to be sized accordingly.  Relay here is a typical Potter & Brumfield  KUP-14D15-24.  See the article about the circuit, "What's All This Solenoid Driver Stuff, Anyway?" by Paul Rako at electronicdesign.com.
