  * Improve the mechanical design

====== What I've done ======

I've made a few more improvements since [[projects:sand_drawing:work_logs:improvements|improvements]].

  * Added optoswitches for zeroing axes,
    * Tabs on arm1 and arm2 to pass through the optos,
    * An arm to hold the optos.
  * Rotated the pin hole that holds arm1 onto shaft1,
  * Rotated the angle of the split that holds the two halves of arm1 together.


====== What I want to accomplish next time ======

  * Assemble everything
