One of the things you will have to do is cut the two slots on top to accept the servo driven face plate support levers.
Then remove the magnets holding the face plate.
Mount 2 servos facing in opposite directions on the inside top between the slots and then make 2 measured/adjustable levers to
connect to the face plate so it pivots upward.
Adjust them so it closes properly, then tighten levers securely...
Make two brackets to hold the servo motors in place.
The speed, pivot angle and servos exact location will need to be factored in.
Many servos will require some kind of microcontroller (PIC, Parallax, Arduino, etc.) to control the servos in opposite directions since they
will be mounted bottom to bottom.
Be aware, you will have to increase your battery capacity and supply voltage to around 5 volts or higher with a regulator to run the
microcontroller and 2 servos.
