HPDV2 dactyl

now this was pretty crazy build
this thing was a split board with modular attachements like touchpad, trackball, big lcd display or rotary encoder.
we did custom pcb for this thing, the deisgner provided left and right side pcb seprately but i modified/redesigned it to have left and right side pcb on one pcb (to save cost) while maintaning the same pinout so client can use the orginal designer provided firmware.
pixart 3389 for trackball and azoteq trackpad.
for the case part the client wanted it to have seamless surface like factory made so we sanded and primer the case like 4 times before spray painting it resulting in the case finish below pretty long and fun build.
