Goals Redefine presentations
Ease of transition between slides
Display more information Minimize computer
interactions Present anywhere on any
surface

Design Specifications –Laser System Four major components: Galvo,
DAC, Laser Pointer, Power Supply Laser - create each pixel of the
projection Galvanometer - reflect the laser
on x & y axis Digital to Analog Converter -
communication between the computer and galvo
Power Supply – The power supply will power the laser and galvanometer
