Summary: A dress made out of LEDs that twinkle like stars.
|
|
|
|
A friend of mine was attending a stars and constellations themed ball. She
|
|
wanted to wear a dress that was lit up with LEDs acting as twinkling stars.
|
|
Seven of the 28 stars are aligned to resemble the Big Dipper constellation and
|
|
twinkle differently than the rest, which twinkle in a random pattern.

## Construction
|
|
|
|
The LEDs came from that strip that was cut up and soldered together with very
|
|
small wires. Each of the LEDs can be controlled individually.

|
|
|
|
21 of the stars are light magenta in color and twinkle by fading randomly. The
|
|
seven LEDs that form the Big Dipper continually scroll through a gradient of
|
|
three colors. Instead of calculating the values of each color in the gradient as
|
|
the program runs, a lookup table is used.
