Key Ideas
The key idea of this project is to create the appearance of holographic text. To accomplish this, we rapidly spin a row of LED's in a circle. The appearance of text is created by precisely controlling when each LED is lit.

LED Timing
The text of the image will be broken up into an array of vertical sections. these sections will be displayed one at a time as the row of LED's passes through their rotational positions. Each vertical section will be switched on for a short time, then switched off in preparation for the next section. This process is repeated for each rotational cycle.

Rotating blade
The "blade" of the display consists of four components; a 3-d printed mount, a LED array, an Arduino, and a 9-volt battery.

Base
The display's base consists of a base board, an Arduino, a speed controller, and a  three phase motor.

Week of April 6
Created new 3-d printed blade complete with LED array mounting holes, Arduino mounting holes, and battery slot. We attached a protoboard, an Arduino, and a battery to the blade. We attached the blade to the three phase motor, and conducted spin tests.
