Above is a block diagram of our system. This block diagram highlights on the main components that will be used in our project. The two most important parts in our system are the vortex cannon and the 2D laser scanner. The vortex cannon generates the smoke rings and the 2D laser scanner illuminate the smoke rings generated by the vortex cannon. 

The block diagram shows the layout of the vortex cannon and the 2D laser scanner are comprised of speaker, H-Bridge, fog machine, ATMega328 microprocessor, and enclosure. The ATMega328 outputs a Pulse Width Modulated (PWM) signal that is then amplified by the H-Bridge and sent to the speaker. Due to the amplified PWM signal, the speaker contracts on the negative peak of the PWM signal and springs forward on the positive peak of the PWM signal. The manipulations imparted on the speaker creates a change in air pressure in the chamber of our enclosure, thus causing the fog placed in the chamber to accelerate forward. The combination of the inward acceleration and the still air outside of the enclosure creates a vortex effect, which results in the production of smoke rings.

The laser scanner components include: Microprocessor, DAC, and a 2D laser scanner. The microprocessor generates and outputs a digital sinusoidal signal. However, because the 2D laser scanner needs an analog signal, the microprocessor first passes the signal to a DAC (digital to analog converter) which converts the Digital signal to an analog signal and then passes the analog signal to the 2D laser scanner. Once the signal reaches the 2D laser scanner, the scanner processes the signal and projects the pattern associated with the signal upon the smoke ring.
