Turning a desk mat into a MIDI drum kit

Playing drums is a lot of fun, but drum sets are very big and very loud. They also aren’t cheap. Those factors keep them from being an option for many people who would otherwise be interested. Conventional electronic drum sets are much quieter and a bit more compact, but they still take up a fair amount of space and come with hefty price tags. That’s why Cybercraftics designed this DIY drum set mat that solves all of those problems.

This is an electronic drum set in the form of a flexible desk mat. It is affordable to build and can be tucked away in a closet or cupboard when not in use. It doesn’t have the same layout as a real drum set, but it can still help new drummers learn fundamentals like paradiddles. Those require a lot of practice to ingrain the motions into muscle memory and this mat makes it possible to run through the rudiments just about anywhere without loud noises disturbing anyone.

Cybercraftics designed this drum mat to work like a standard MIDI (Musical Instrument Digital Interface) input device, but with piezoelectric sensors instead of buttons. Those produce a signal when struck. They are analog signals and there are seven sensors, so this project uses an Arduino Leonardo board that has enough analog input pins. The Leonardo also has a Microchip ATmega32U4 microcontroller, which means it is configurable as a USB HID — handy for interfacing with whatever MIDI software you may want to use.

On the physical side, this is just two desk mats cut and glued together, which circular pieces covering the piezoelectric sensors. A small 3D-printed enclosure protects the Arduino.

If you’ve ever wanted to get into drumming, this may the opportunity you’ve been waiting for.
