![]() ![]() But the shell is where the creativity really shines through. Being an off-the-shelf drum head, it has a good feel and playability. For the striking surface, a Tama-brand mesh drum head is used. To solve that, decided to design an E-drum pad made with paper & 3D printed parts.Īs far as E-drum triggers go, it follows the basic rules - a piezo element used as a trigger with some foam used for damping. That’s easy enough, but the mechanical design can be a difficult problem to approach. The concept behind DIY electronic drum kits is fairly simple - small piezoelectric elements are used to generate a voltage when the drumpads are struck. When we last heard from him, he was turning a very pink keyboard into his own personal circuit bending playground.Ĭontinue reading “Arduino Drums Bring The Noise, No MIDI Required” → Posted in Arduino Hacks, Musical Hacks Tagged drum kit, electronic music, midi, synthesizer is no stranger to homebrew electronic instruments. In the video after the break, you can hear the results for yourself. ![]() Actually getting the beats out of the Arduino required the addition of a R2R DAC circuit and a TDA2822 amplifier. Check out the custom impact sensors lovingly crafted from popsicle sticks and metal cut from soda cans, which have been mated with sections cut out of old DVD-Rs. Though it sounds as though there might be a solution to this soon for those who want to play along at home.īut don’t get the impression that this project is just software. Unfortunately, since the samples are essentially part of the drum’s source code, he says distributing the firmware is something of a problem. One of the trickiest aspects was storing the samples: the 8-bit, 11.025 KHz mono WAV files ultimately had to be converted into C data arrays with a custom Python script. To be sure, this is a lot to ask of an 8-bit microcontroller, which is probably why nobody does it this way. That’s fine if you’re just looking to build your own hardware interface, but he wondered if it would be possible to forgo the MIDI device completely and actually generate the audio internally. When looking through existing Arduino drum kit projects, noticed that most of them just used the microcontroller as an input for an existing MIDI device. ![]()
