I am a graduating student of the Design Academy Eindhoven and I guess I have a very simple question : I made this circuit with an LED that turns on when you blow on the piezo, but I have two questions about it :
- how to integrate the circuit into an actual lamp? replacing the one single LED by LEDs trips and connect the whole circuit to main supply (not the computer), around 12V
- This piezo is not very sensitive because of its plastic shell around, does anyone know where precisely I can find an uncovered piezo sensor, with a bigger reacting metallic surface?
Thank you a lot!
