1. LASER GEOMETRIC PATTERNS PROJECTOR
 |
FEATURES:
4.9 mW Red Laser Memory of 16 patterns Display controlled by variable speed timer, or music triggered. Also Manual mode. Power supply included. Also can operate on 4 AA batteries. Mounting yoke. |
 |
OPERATON: The laser beam bounces off a first mirror, which is mounted off axis on a stepping motor. Next the beam bounces off a second mirror, also mounted off-axis on a second stepping motor. Under Manual control, the user can adjust the speed of each motor, creating a wide variety of geometric designs. Under Auto control, the memory cycles thourgh 16 combinations, producing circles, stars, multiple loops---see below. |
1. LASER GEOMETRIC PATTERNS PROJECTOR: 8" long x 3" high x 5" wide, not including yoke; 1 pound ........ Model GPP-1 ....... $200 ( Reduced April 1998 ! )
| SAMPLE PATTERNS
Shown are just 7 of the 16 patterns stored in the memory, which are displayed sequentially. Time between change-of-image can be adjusted by the timer; or triggered by music picked up by the built in microphone. Actual color of beam is red. In the Manual mode, many more patterns can be created by adjusting the speed of rotation of each of the rotating mirrors. Image size is determined by the distance from the projector to the screen. Safe to project into a crowd; but do not stare into the beam. Use with Roctronics Fogger (see FOGGERS ) to create mid-air tunnels. |

Tunnel effects can be produced by passing beams through smoke created by a Roctronics Fogger. See FOGGERS in Yellow pages. Blue-green color shown is produced by Argon gas laser.
