UPDATE: GPIO to MOSFET without a resistor? Am I crazy? Yes, I am. See: How to Fry your Pi

The circuit of this project is very simple. The Raspberry Pi's GPIO (out mode) switches on the power MOSFET which controls the high-consuming solenoid.

This is schematic of the current working circuit. There are important notes:

This schematic is not perfect at all, but it works right now. I would really appreciate your help to make the circuit better.
