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.

I'll also be adding the ability to trigger the camera shutter with the joy stick, but I don't anticipate any trouble with that part; it's the motion control side that I have no experience with. > > > > Any suggestions?

My degree is in EE, but I haven't used it in ~20 years, so I'm kind of rusty on the electronics side but I'm sure it will come back. > > > > Dave > > > > > > _______________________________________________ > > geda-user mailing list > > geda-user@moria.seul.org > > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user > > > > > _______________________________________________ > geda-user mailing list > geda-user@moria.seul.org > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
