Lo-Fi Noise Machine - Overview

Introduction​

Lo-Fi Noise Machine Kit is a fun, educational electronics project that teaches you the fundamentals of soldering, and at the end you get a really cool sound device! This kit lets you build your own analog noise machine, creating Lo-Fi tones with no digital sound processing or software involved. It features a buzzer, an 8Ω speaker, and a 3.5mm audio jack, giving you the flexibility to choose between three different sound output options depending on how you want to use it.
