Today, the sensors have all been sewn onto the shirt. We spent a long time sewing conductive thread from the sensors to the arduino wires thanks to the obstructing optic wires on the shirt. We ran out of conductive thread again today, and had to resort to buying conductive thread from classmates. But little did we know that the new threads were a lot thicker than the original ones that we were using for the past 2 projects. The new thread barely fit into the sewing machine's needle, but it did in the end. Though, the sewing machine started to jam up the threads even more frequently with the use of the new threads, we are thinking it must be because the thread is too thick and that the underlying thread is not thick enough - but we are just making guessing. We were quite pressed for time, so we ended up resorting to sew by hand once again even though the handiwork is not as neat as the machine makes it, but we have to do the best we can.

We also glued the LEDs to the fiber optics with a glue gun. The first time we tried it, the fiber optics bent away from the heat causing the group to split instead of converge. We experimented with it a couple more times before deciding to tie the fiber optics together first and then glue it to the head of the LED. We had to sand down the head of the LEDs before gluing, it was hard for the LED to stay in place when the ends of the fiber optics were sliding from the round surface of the LED head.
