This has taken slightly longer than I expected - I can only work on the design over my lunch breaks, and had some un-planned meetings pop up that kept me away (I only have 3 lunch breaks a week in the office which also slows things down...).
Anyway, on Thursday the design was complete so I cut the various panels out and took it home for a test build.
That didn't go too well as I then discovered a couple of points where I'd miss-toleranced so it wouldn't go together, all were quick to alter so the offending articles were re-cut on Friday and taken home again..
It's still only a 'dry' build at the moment as I need to tap some holes for the clamping mechanism, which means I can't glue it together or finish tidying the wiring yet - but I've plumbed in all of the rear expansion connectors which allows me to add the home made sequential.
And I've also bodged the dual-encoder onto the end of the cable which will eventually connect a floor mounted H-pattern to the setup (the encoder will be wired internally once I'm at a stage where I can complete the build (next week!)).
It's slightly annoying at the moment as I'm not used to it - which makes finding it in the Rift quite hard, especially as it's currently unglued so the button panel tends to get knocked off/apart by my flailing hands
Once it's glued and I'm used to it I'm sure it'll be worth it's weight in gold.
In total the button panel itself has 4 encoders (2 single, 1 dual - all with integrated push buttons), 2 toggle switches, and 2 push buttons.
The connectors on the rear also allow for the sequential stick, a 6+reverse H-pattern (not started on yet), and a handbrake with inputs for both analogue and digital feedback (design mostly complete).
