I have an idea for making modular panels using a combination of magnets and Velcro based on a single frame with a large cutout area, then using single panels wired up with Molex plugs that connect to the main harness, which mount with strong magets or velcro to secure them.
I'll need to replicate an Asteroids panel with a huge open space and mount megents to its underframe, then have panels made for button and joystick layouts (plus driving wheel, trackball, yoke and spinner cutouts), which I think I'll have a machinist that I know (who owns a waterjet and some heavy-duty laser equipment) make out of black plexiglass and install magnets into the panels. The Velco idea is a backup plan in case the Magnets prove unreliable.
I think this is a more interesting and more easily swappable design than the rod-based design that's already been showcased, and once I get some spare time and finds to start it, I will do a thread and post my progress for those who want multi-panels without going nuts and adding everything. (I dislike huge panels).
What I see the need to have is the following:
Digital (4/8-way) Jotstick panel (x2)
Analogue Joystick panel (x2)
Rotary joystick panel (x2)
Trackball panel (x2)
Spinner panel (x1=Arkanoid type & x1=Tempest type)
6/8 button array (x2)
5-button 'Asteroids-type' button array (x2)
Star Wars yoke (x1)
Steering wheel (x1)
Driving pedals (x1 set)
Skiing controls (x1; for 'Slalom')
As you can see, tats miles beyond what any singular panel can hold without being obscene, so I'm going to he modular route. Wish me luck... -GG
