The original thread is here -
https://geekhack.org/index.php?topic=41422.0 - Which I kind of inadvertently muddied with my take on this device.
Got 3 ballheads - One lets me adjust the position/angle of the swithes support, second, the whole assembly moves to whatever angle needs to be, clamped to the chair armrest or to a desk, third, the hand support piece angles independelntly for maximum comfort.
The main piece is slotted so the whole device goes up/down relative what is attached to.
Ths is work in process, unless asked I wont upload the files just yet.
To do:
I want to fuse all 5 switches with the switch plate so there are less parts to assemble and prone to breaking.
Make the center button/switch easier to assemble, althought I made it work, is hard to put it together, not alot of tolerance/room for mistakes, the switch pressing area is 1mm wide, less than 1mm travel distance and fairly sensitive.
