Yamaha DTXpress/DTXplorer/DTXtreme

Thanks to the inspiration of Gary in post 3042, and his
informative web site ( http://oneaccord.homestead.com ), 
I was inspired to build my own pad. I had wanted a pad 
to use as a cowbell/woodblock. I researched DIY eDrums 
and found http://edrum.for.free.fr/index.php to be very 
helpful.

On this web site there is a simple plan by Michael 
Beatnik called "Mini Trigger". I don't want to copy his 
plan here without permission but you will be stunned, 
as I was, at how cheap and simple it is to make using 
just the following from Radio Shack:
    1- piezo transducer part #273-073 
    1- 1/4" phone jack (mono) part #274-252 
    1- project enclosure  3x2x1 part #270-1801 
    double sided foam tape or hot glue
    1- 2x3 inch piece of rubber from a mouse mat

It cost me less than 8 Australian dollars, which is less 
than US$4, and it took me less than an hour to do it.
 
It works perfectly.
