Note that the 555 can't power the solenoid directly. An N channel FET or an NPN transistor is required. Also, to get the different duty cycle the 555 board needs a diode in the timing circuit. You can bodge it in if need be.
I'll post a complete schematic and suggested parts today, and plan on doing a build soon to validate it.
