This project came out of Boston Hardware weekend as a way to explore the Intel Edison. It uses shields from the Grove Seeed Starter kit and the Arduino Edison IDE to run a web server that listens for a command to open the jar via the servo, waits 15 seconds for $ to be deposited, and then closes.
The other half of the project uses Google's Android Speech to Text library in an Android app. The app listens for keywords (both swear words, and hacker buzzwords, so you don't have to swear to check it out!) and uses the Internet to access the server running on the Intel Edison and open the jar!
If you have an Android phone and are on the same Internet local network as SwearJar, you can try it out by installing this app onto your Android phone:

Sample pitch (clean!) that will trigger SwearJar:
"We are seeking Venture Capital for our Internet of Things platform to allow users to socially leverage eating cardboard in the Cloud!"
