On the subject of sound
September 17 2013
If you, like me, get the urge to play around with piezo discs, I came across this inspiring video demonstrating a few ways of using transducers of different kinds when working with sound and material.
And by the way, should you run low on stores/money/imagination, you can also look up and reach for your fire alarm (be sure to replace it!). The part you are looking for is also the same part that is making the pleasant noise. Usually it looks like a metal ring with a membrane. Most alarms have them and they work great both in sensing vibrations and transmitting sound depending on how you use them. Enjoy!
