Learn how to make a laser pointer using a 5mW 650nm laser diode module. With proper assembly—including a copper-heated enclosure, controlled current, and secure wiring—a durable, safe, and efficient laser pointer can be created for personal or educational purposes. Most of the materials mentioned in the things you'll need section can be procured at online shopping sites or hardware retail shops. Some, such as the laser diode, can be found in other electronic devices. A laser diode is a cool component that you can do a lot of fun stuff with, from engraving wood to creating a light show or giving your robot eyes! They range from super cheap (or even free if you can find one in an old CD player!) to more expensive. A laser diode is a diode which outputs a laser beam. Unlike LED light, a laser's light output is more concentrated, meaning it has a smaller and more narrow viewing angle. This means it must be directed at its source.
