Hi

I must admit that I've jumped out in Arduino, and this kinda kit: 
http://microdrum.altervista.org/blog/info/

I think it looks exciting and lots of fun.


BTW. I already succeeded building a trigger with an angel bracket, a 
piece of rubber-foam "20x30x70 mm", a 27mm piezo transducer and a bit of 
glue, and mounted it inside a drum shell, with full contact to a mesh-head.

It generates sound when connected to my sound card's preamp, so I assume 
it will do okay for the project.
