This week on the chess pieces part, we changed our design a little bit after discussing with professor and TA. Instead of 3D printing we will be laser cutting frosted acrylic sheets and glueing pieces together to make sure the LED lights on the board can be seen when pieces are placed on the grid points that are supposed to light up to indicate suggested move. So I made new CAD drawings for the pieces, and will be cutting them out next week. 
I also have the board design. It will be cut out with plywood next week as well. There will be details that might change as I get to designing the holder for phone.
I am working on the computer vision portion as well, and after pieces and board gets cut out next week, I will be able to move on to adjusting and calibration with actual pieces and boards.
I am on schedule with computer vision, and next week I will be manufacturing the chess pieces and boards.
