This week on physical device side I cut out the second layer of the board to hold the leds in place. I worked with Claire to make sure the design does work. 
For more on this part I will need a piece of design to hold this layer in place in the box, hopefully a design that will enable us to take this layer out of the box easily for led replacing. Will do during the integrating part towards end of semester.
For cv, I took videos of pieces on different positions of the board and took out 40 frame for each set for yolox training. There are 11 sets of images that I labeled. Chariot, horse, and cannon have same characters for both sides, to they each make one set, 20 images for each color. The rest of the pieces have different chinese characters for each side so they each make two sets, 40 images for each different character. 
I made the ratio of training and validation set 8:2 so 32 for training and 8 for validation.
Setting up the environment for YOLOX somehow got extremely frustrating for me, couldn’t get it to work on my mac, had to set up a whole system on a pc. A little behind on schedule, should train all datasets this week, so I need to do more work this Sunday to make sure I don’t set my team back.
