I Made a Drum Machine for $70!

Here’s a Drum machine I designed and built over the last 3 months using a Teensy 4.1 as the main brain. The total build cost was about $70, 30 of which was the Teensy itself. I’m pretty happy with how it turned out and I´m considering making a 2.0 version in the future that will be for sale! Here’s a link to the Code, Schematics and more information about the project: 0:00 - Intro 1:00 - Funky Jam 1:30 - Hat n Snare Jam 2:00 - Ambient Industrial Jam 2:30 - Fast DnB Jam 3:25 - Walkthrough 4:25 - Kicks 4:40 - Snares 5:20 - Hihats 6:25 - Other Functions 8:10 - FX 9:00 - Outro
