April 10th, 2010 – Have you ever wanted to make a contact microphone on the cheap? After paying hundreds, if not thousands of dollars, for nice ribbon, condenser, and dynamic microphones, the last thing many of you want to do is spend a lot of money on a microphone you will likely not use as often.
Well contact, or piezo/pickup, microphones can be made very cheaply. If you have a soldering iron already, you won’t need much more than some wire, a $1.50 transducer, and a 1/4 inch adapter, to make your own. If you have those materials already (and you can find transducers from those audio greeting cards), then it could potentially be free.
The project takes very little time to do, and could allow you to record some very interesting sounds.
