Easy 3D Printing
Welcome to Arduino
If you use a MUCH bigger MOSFET, this could work. The NE555 is rated to 15V, so battery voltage shouldn't be a problem (A resistor/zener diode combo can be used on the input to bring it down to 12V if you're concerned about that.) You could use an LM7812 to regulate the voltage as well, but it will need another heat sink.
