There's a lot of electronic bagpipe development going on right now, ranging from DIY projects like Frankenpipe, to commercial products vPipes and ePipe. These electronic bagpipes look and sound great, but the commercial products range from a few $100 to $5000, and the non-commercial published projects typically lack enough information for a DIY to reproduce the design.
The eChanter aims to bridge the gap between the commercial products and the DIY projects, while meeting fourbasic goals:
1. "Open Design" that can be made by anyone with basic electronics skills
2. Costs less than $100US in materials
3. Use minimal number of components
4. Use the Arduino platform for software control
