Re: gEDA-user: OT - Joystick control of stepper or servo motors

[Hannu Vuolasaho <vuokko@xxxxxxx>]

   Does it have to be a joystick? I have found quite usable small
   touchscreen and one button. It is like trackpad in mouse size square
   box and my thumb pushes the button on the side. I use this with my PCB
   driller to place it right place. First I have to use footswitch to
   operate the arm and then I just slide drill to first hole and push the
   button. The arm lowers and I can see where the drill will actually
   contact. And I can't see my hand. Right hand is keeping door open and
   my left is operating the arm. My head is inside the machine.
   Just a thought.
