Meeting #2,

Brainstorming Session: 21st November

Discussing the research that was made beforehand to fully comprehend the spectrum of our project. Deciding on the project idea and its execution. Sketching the bodysuit and bra, finding the right sensors and interactions to match the movement and music. The project includes a dance bodysuit with knitted flex sensors on it to detect movement, then the bra would have a microphone at the back to detect the music’s beat. LED strips and LEDs would then be added on the bodysuit and bra. The movements would affect the LEDs’ pattern, the brightness and the colour of the LEDs flashing. The microphone, on the other hand, would determine the speed of the animation through the tempo of the music.

Meeting #3,

Low-fi Prototype 1A: 25th November

Wiring fabric containing knitted flex sensor to the circuit to test the output on the Serial Monitor. Several tests and attempts including: lighting up LEDs to find thresholds, calibrating the fabric in the code, trying to stretch the fabric and inspect the values on the Serial Monitor. The flex sensor proved very temperamental to work with, making the results quite unreliable.

Meeting #4,

Low-fi Prototype 1B: 27th November

Twisting the legs of LEDs to make a hook that can be sewn on the bra using wires and conductive thread. Calibrating the flex sensor for accuracy and a reliable answer with a threshold, changing the code in order to get an input on the Serial Monitor.

Meeting #5,

Low-fi Prototype 1B: 2nd December

After receiving the sound module, sketches were made to test the detection of sound and the beat of the music. The sound module, unfortunately, cannot detect the beat, just the presence of sound. Different attempts were made with Arduino to check for sound detection and increase sensitivity and threshold to test.

Meeting #6,

Final Project: 4th December

Preparing the RGB LEDs, white LEDs, wires and coding the final prototype. These elements are essential and need preparation before sewing. The LEDs legs were twisted to be sewn after differentiating anode and cathode. Wires were colour-coded, cut and placed in advance on the bra.

Meeting #7,

Final Project: 9th December

Sewing LEDs on the bra and white LEDs in columns to act as strips on the mesh bodysuit. Preparing resistors to be sewn.  As a substitute for the LED strips, 20 LEDs were wired in a column on the bodysuit, 10 on each side and 6 shift registers were placed in between for easy wiring of the LED bra and the strips.

Meeting #8,

Final Project: 10th December

Preparation of the 330 Ohms and 560 Ohms for the RGB LEDs and white ones. Coding and figuring the number, grouping and the placement of the shift registers. Wiring everything together, and testing it. The conductive thread was very unreliable for a constant connection, use of wires in between LEDs by hooking them to LEDs and resistors. The connection was not always reliable which cause the LEDs to not always light up or required someone pushing on the fabric to force the wires to touch each other. The LEDs on the bra were grouped by 5 to give us 30 LEDs, this mapped out to give a star effect all over it. This also includes the attribution of LEDs to the registers.
