The machine in the video is a so-called laser show machine. It cost me around 90 dollars on Aliexpress and is a lot less than I was expecting. For example it doesn’t even have music control where the laser is moving with the beat of the music. That’s why today we start making a homemade version that should be a lot better. First we will take a look inside of the commercial machine and then, make a plan on what we need for our homemade one.

I’ll try to use parts that are not expensive, and like that, maybe get not just a better version but also cheaper. We will solve the supply problem, analyze the sound with a microphone and an Arduino. We have to find 3 different color lasers, merge the light into just one and then see how to move the light and create shapes. This project will be made out of 2 parts. So guys, let’s get started.
