Front view. Agatha Christie approves.
Another front view,
slightly different angle for dramatic effect (try to contain yourself).
Note that the electronics haven't changed just yet. This is simply a new package for the same device we've demonstrated earlier.
This button arrangement worked out beautifully for my sister, but it turns out it doesn't fit on her tray! She uses a joystick to drive the chair, which stands about 6" high and sits at her right hand. Her left hand is strapped into a permanent support on the left side of the tray, giving me about 10.5" of useable space on the tray, right in the middle. This body is just over 18" wide.
I had spent so much time designing the body itself that I didn't consider the available room on her tray. You can't see it, but I'm banging my head on my desk. Rookie mistake.
This is what R&D is all about. Trying to anticipate everything, and then trying to fix what you didn't see coming. In this case we'll need another body design, but I now have some experience with that so the next one should come much more easily. The electronics still need to be repackaged as well, so I will try to incorporate that into the next design.
Stay tuned for more updates as they become available.
