The world needs your light....
Meeting started at 2:45 p.m. at Ngee Ann Polytechnic
Half of the projector has been completed. The heavy base for added stability is now in place and the rotating mirror is ready and working. It spins at a high speed to generate a centralised image in the middle of the vortex while the laser beam is dispersed into a 360 degrees arc in the surroundings, creating a visual impact.
Meanwhile, we added 2 more screws onto the base of the rotating volumetric screen for added security. It ensures that the screen will remain tightly attached onto the heavy metal base and will not start moving when the screen spins, which can be extremely dangerous and hazardous to onlookers.
Next, we decided the arrangement of our circuit components, ranging from our Compact Visual System, our Digital Signal Processor, our laser power supply and the laser controller. We placed these components in their approximate positions and stuck masking tape on these areas so that the lab technicians knew where to drill a hole into the heavy metal base. We intend to connect our electrical and digital components by Thursday.
Finally, we placed an order for a perspex box, which would allow us to see through into the image, but it ensures added security as well because should the volumetric screen fly off its support while rotating at a high speed, the perspex, being a tough material, would weaken the impact and lower the speed of the screen so as to minimise damage and hurt.
Meeting ended at 6:00 p.m.
