Make your own Force Sensitive Resistor

Build your own force sensitive resistor that can be used to control LEDs, make a sound clip play, and control a variety of other devices. Best of all, it can be made for less than 20 bucks. An easy way to create touch sensitive lights and experiment with the capabilities of a force sensitive resistor. The resistor uses parts you probably already have around the house, solder, hot glue, an a copper circuit board. The only thing you may need to buy is the conductive foam. For more pressure sensitive fun, check out the fabric based pressure sensitive resistor shown in the video above. This hack can be set up in a few minutes, giving you more time to have fun with your new resistor.
