Show | |
| With this laser show many different figures can be projected to the wall by means of a laser. With 2 controllers you may regulate 2 reflecting motors via the installed electronics so that a lot of different figures can be shown. The necessary laser is not enclosed. The following are suitable as laser: laser pointer or laser modules which produce a laser point (without installed dispersing lens). Operating voltage for the laser show: 6 V=, max. 0.3 A. | |

The board has to be tipped according to the
drawing. Please pay attention that the IC is installed in the right
direction (on one side of the IC there is a notch which must match with
the print on the board). Also the elca C5 has to be installed in the right
direction (the negative pole of the elca is marked). The enclosed mirrors must be glued on the mirrow supports of the motor with a liquid adhesive (e.g. "superglue"). A consistent adhesive (e.g. hot-melt-type adhesive) should not be used as otherwise the mirrows do not lie exactly on the mirrow supports which would cause a change of the setting angle. In order to operate the circuit please use either batteries (e.g. 4 batteries "monocell" of 1.5V each connected in series produce 6V) or a power unit with a stabilised output voltage of 6V direct voltage, at least 300mA or more. According to the drawing the motors must be arranged in such manner that the laser beam meets both mirrows at the motor (after adjustment the motors must be glued on the board with adhesive). Both motors are controlled with the potentiometers. Pot P1 controls the rotational speed and direction of rotation (in neutral position the motor runs slowly, the more you turn to the stop at the left or right side, the faster the motor turns to the left or to the right). Pot P2 controls the rotational speed of the other motor: from very slow to very fast at the same direction of rotation. Depending of the luminous intensity, the laser show is placed in front of a white wall at a distance of 0.5...2m and the laser figures are projected to this wall. Many different laser figures can be produced through slow adjustment of both potentiometers. Please do not turn the potentiometers too fast due to the fact that the motors have a slowing-down time and the new adjustment only starts after approx. 1...3 seconds. The operating voltage of the laser depends on the applied laser. The operating voltage for the laser should not be drawn from the same 6V - supply point which also operates the laser kit! If you use a laser pointer, it must be mounted outside the board and according to the drawing it has to radiate into the rotating mirrows. Small laser modules can be mounted directly on the board in front of the laser mirrows. |
| Safety instructions for
lasers: Laser beams may damage the eyes severely or may cause blindness if they radiate into the eyes directly or indirectly. Therefore the laser electronics must be installed in such a manner that radiation into the eyes will be impossible neither directly nor indirectly via mirrows in the room. Furthermore, when using lasers with a capacity of > 3mW the legislator stipulates that a "safety officer" must be appointed who inquires about the legal regulations for prevention of accidents respectively valid for installation of lasers and who takes care that these legal regulations are observed! | |
