What does a circular laser pointer look like?
Having all the energy and converting it into light energy is impossible to waste energy. Moreover, documents and clothes are unlikely to show signs of fading. Since the wavelength of 460nm is a bright blue close to sky blue, it is a highly recommended product and can be used as a pointer in speeches and lectures. After drilling the holes, pull the red and black cables back from the original holes, and rewire them as shown in the figure below. Scotch tape is temporarily fixed. After wiring, pass each cable through the hole you made earlier. Then, cut the cable to the length shown in the photo, and remove the approximately 2 mm film from the tip.
