Week 3 : Electronics production (Feb 18)

1. Vimeo Links : One, Two

2. Tryouts

   A. 2D Design (Inkscape) : downloaded Inkscape and Xquartz to launch Inkscape.
      Tried to draw a pcb like image and draw 3D Boxes.






   B. 3D Design (Antimony) : Continued trying out Antimony.
      Git Cloned the 3D model nodes to have torus and multiple models.
      Tried on the exercise that professor Gershenfeld did during the lecture.





3. Assignment
   A. Make something that makes something : Inspired by the MTM(machine that makes machine) stages,
   I wanted to replace the two beams(aluminum here, numbered 1) with the cardboard.
   MTM snap gave an similar idea that simply interlocks two parts.
   I will call it a MTM X-Beam(the beam creates the letter X, and also
   two X's are used at the end of the lock). Here I used only cardboard to make it.
   However, if the nylon bearing fits in-between stages and the beams it will decrease the friction.




   B. Here is the test. The radius of the circlular shape at the end is 15mm and the radius of the arc is tested with multiple values.






   C. Here is the second version. There was a difficulty as the type of the cardboard is changed.
      The white cardboard needed more power and slower laser move.
      As the cardboard showed the weakness at the X interlock, the improvement came at the final.





   D. Here is the final version.
      Because the X-shaped cut was weak,the circular strut placed at the center of the X shape.
      Finally the MTM stage beams are replaced with the MTM X-beams. The joints of the beams are fixed well with the stages.
