Did you ever wonder how to utilize the exess pcb. Use it for buttons !
How would you make a diy keyboard/game controller. It should have one eyeball stick controller and x number of cherry mx buttons for game interaction. And it shall have haptic feedback
Im thinking trigger finger is the same as PS 2. Two cherry mx per side, at an angle.
Then some function keys. Maybe a onehanded controller is better. The eyeball joystick shall be springsloaded.
