Abstract:

The 68HC908QT4-based laser projects onto a primary offset mirror. The primary mirror spins a circular image onto the secondary mirror, which is also spinning. The secondary mirror then projects the first pattern onto a wall or screen. The difference in mirror speeds of the two motors creates spirograph-like images.
