Anyone made a auto 4way/8way switching joystick?

A small solenoid to lock the rotation of the restrictor. Solenoid pin just goes in/out of a hole in the plate.
Maybe use a motor with a worm gear to rotate the restrictor. Then use an optical sensor to know when it is done, which then tells the previously mentioned solenoid to lock the plate. Obviously this means a custom made restrictor plate that matches the gear on the motor.

Still think the servo thing is much cheaper and easier to do than this, but when I was considering things I thought about that. For this, instead of a custom plate I considered attaching a lego gear to the current plate and build everything from technic parts. (Acquiring individual technic parts is cheap and easy from bricklink)

Sorry to revive an old thread, but I just completed a new cabinet and was checking to see if anyone else had done the auto 4/8way joystick.
I'm using Ultimarc Mag-stick plus joysticks, and a Pololu 6-channel servo controller. When the game is selected in the FE, a small batch file runs that will automatically tell the servos to move to the 4 or 8-way position and then run mame. Works a treat- I'm really happy with the result

Looks good!
Does that stick restrict actual diagonal movement when in 4 way, or does it just disable diagonal switches?

Yes, when in 4-way mode the stick is physically incapable of moving to the diagonals

Can you post video/build pics/parts list/batch file? (yeah, I asked for everything+kitchen sink...)
That looks really neat and might not need this servo that I looked up...
