From Matt Reed:
Deadhand is a simple remote that can be used to call ("trigger") any url. When the button is pressed and held the remote is armed. When released it will call the url of your choosing with the option to abort the call by sliding off of the button. Any break in contact with the button will call your configured url.Since you can point the remote at your own server you can easily customize the commands, and therefore results, of the remote call. Use it to add dramatic effect to the launch of a website, the choosing of a contest winner, updating a database entry, sending an email...the possibilities are as endless as your imagination.The server response is shown in the digital display. The default testing script provided with the app returns "DEPLOYED" from the remote server http://deadhanded.com/test/. You can easily customize your own response message on your own server.Example server scripts are available at http://mcreed.com/deadhand
