This week I fabricated a $20 value poker chip as well as building the base contact for the chips. In addition I tested stacking multiple chips and measuring their resistance directly with a multimeter. The chips when stacked sometimes do not fully contact, but with design adjustments, that problem can be eliminated.
The shuffler and dealer complete module cannot all be 3D printed due to cost. The outer card holding base will be constructed from wood, since precision is not a major concern with that part. The dealer and shuffler modules will still be 3D printed, in order for the necessary precision to be achieved, as the motors and gears need to be able to fit in the right places and rotate as necessary.
The schedule is on track and we should have two functioning subsystems by the end of this coming week with adjustments to the chip subsystem that are necessary. We will also construct the exterior for the shuffler and dealer and begin the assembly of the motors, gears, and electronics if time remains.
