From the project
Piezo sensor-based MIDI electronic drumkit
Shiva -------------------------- Up to 8 piezo sensors with MIDI out (standard and USB) to make an electronic drumset
Proof of concept done with an Arduino Micro board (click on the images below to go to the videos):
Inspired by KORG's CLIPHIT Conditioning circuit for piezo sensors is based on ScienceProg's circuit

Shiva: common questions
How big is the Shiva PCB?
The Shiva measures 99.8 × 99.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Shiva?
70 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Shiva design files?
From the UC3Music/Shiva repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Shiva design in my own project?
The repository has no license, so all rights stay with UC3Music. Use it as a reference, and ask the author before reusing the design.
