2015-09-29 (Tu) Wrist Mounted Chording Keyboard

Modeling was done for a five-part platform to hold the keyboard. The concept was to mount a countersunk magnet to the hole in the flat area and a similar magnet would be on the keyboard. Magnets would allow the keyboard to rotate freely and be instantly removable or kept in place while typing. Four spacers were rendered separately so their size could be adjusted individually. It may be important to make a pair shorter or longer than the other pair so the magnet would not be centered.

Model of keyboard holder with indiscriminately sized spacers

Magnets were ordered domestically. Two countersunk magnets were purchased with the intention of mating them face-to-face so one magnet was ordered with the countersunk face as the north pole while the mating magnet was ordered with the countersunk face as the south pole. Identical magnets would naturally repel.
