[sdiy] Time for a NEW string - Piezo Switches!!!

[Peter Grenader]

Guys,

I have 10 piezo switches. They are kind of like the ones shown as the site
backdrop here:

But those have tactile feedback - mine are just flat clear annodized
aluminum.  They are made by Peizo Develpment Inc. Two wires coming out the
back.  Anyone have a drive circuit for one of these babies?  I just want to
get a pulse out that stays on as long as the button is down.



Let me know and thanks,

Peter
