HeavenEverywhere DrumHead Open-Source Hardware Project Page
Overview
The HeavenEverywhere DrumHead is a 1-piece E-drum trigger processor and high-quality PC-based sample player. The DrumHead system uses off-the-shelf components and DIY kits; anyone who can solder and follow instructions can make this. There’s no complicated electronics involved, just simple hardware metal-work and making several cable harnesses. The system is based on the MegaDrum trigger processor (http://www.megadrum.info) and a standard PC motherboard.
