LIGHT EMITTING DIODE SPHERE

I designed and developed an electro-mechanical light show which consisted of two simultaneous degrees of rotational freedom. LEDs situated on the spinning frame traced the outside of a sphere as they spun, creating a light globe effect. Data and power were connected to the motors and individually addressable LEDs by the use of a slip ring on each axis, allowing infinite rotation of the LEDs. I machined the structure from aluminum using a CNC mill, used a laser cutter and 3D printer to make parts for the spinning inner gantries, and used an Arduino Uno along with a motor shield to control everything. A variety of off-the-shelf components were also incorporated into the design including bearings, motors, slip rings and the LED boards. The project was self directed, with just the prompt ‘make something that makes you or someone else happy’.

PROMPT: Create something that makes you happy.
