I have just invested in a couple of items for my visual pinball project. 1. Solinoids - these will provide tactical feedback 2. Relay board so when I press my flipper button it can run both the solinoids and the keyboard input 3. Nanotec nudge + ball plunger board. I have read about shakers but this is not used for all tables and I am really limited on space on my coctail table sized version - so not really an option. On my real table I can feel vibrations as the ball moves about - is there any such simulation devices that do this. I am really interested in what other "tactical" feed back devices have people added to their machines.
