3.7.1 LAG Design The initial concept of the LAG is shown in Figure 23. In addition to the basic concept of shining a laser to line up the camera, we added a safety feature to the laser circuit, assembled the components, and did performance testing as shown in Figure 24. The components are: ● 532 nm 5mw green laser pointer, which was originally purchased in Rome, Italy in 2014 in the ruins of the old Roman Empire ● Rayovac High Energy 9V battery

● 20A 12v 3 terminal switch ● Tactile momentary switch ● T type 9v battery connector ● 20 AWG wires
