Table Top Drums

This is a table top design I just finished. What I was trying to do is get the placement of the drums pretty much as they are on my full size set. I will trigger an Alesis D-4 with this. I also wanted something I could run midi out direct to my computer cause I want to try recording some midi in Traction and then use SFZ to convert the drum sounds. The triggers are made from a piezo glued to a CD then I used silicone to glue foam on either side. I have only done preliminary testing but they seem to work pretty good so far I'll post more once I get them all wired up.
