2 the LEGO-compatible laser

Lasers fascinate people, and they’re useful too; you can use them to project a beam over a long distance, make animated light shows, measure distances, experiment with the wave nature of light, and create holograms. It’s natural to want to add a laser to LEGO inventions. Unfortunately, LEGO doesn’t offer a LEGO-mountable laser, probably because of the safety issues discussed in the following box.

In this chapter, you’ll build your own LEGO-mountable laser to use in future projects. This laser will use a LEGO-based battery source, so you can incorporate the power supply into your LEGO contraptions as well.
