Motion Feedback MP3 Trigger

by on Apr.07, 2010, under technoPHILE

I posted over at Instructables a project that uses the Parallax PIR Motion Sensor (yes, it IS that same I used in the Halloween Hack, ye of the clan Observant) to encourage me to be working out. If I am, then I am rewarded with some tunes to keep moving along. However, if I am lazy and take a breather…well….. “No Snoop For You!”

The Parts List:

  • SparkFun MP3 Trigger
  • IO-204 Control Module
  • Parallax PIR Motion Sensor
  • PC Speakers
  • Coffee Tin
  • Drill
  • 6xMachine Screws, and 12xNuts

  • Key objectives here:

  • Try out the SparkFun MP3 Trigger
  • Finally get a project into an enclosure that I think will be good for other people’s projects (this could be the next Altoids contender?)
  • Delve into “Onboard Rules” functions of the IO-204 while offline
  • Assembled parts used in Motion Feedback MP3 project

    If you want more details, head over to the Instructables post.

    Here is the project enclosure. Admit it, you love you some Maker’s Notebook, too, don’t you? The MP3 Trigger sits snug as a bug in a rug with the machine screws and nuts anchoring it in place. 2 additional ones hold the PIR Motion Sensor to the front of the tin. Getting the larger hole in the front and back was tricky because I did not have a great pair of snips around. I’ll know for next time! I did manage to wear through several Dremmel bit tips in my stubbornness of using the wrong tool for the job.

    Here she be all wired up. Note, she AIN’T wired to the LAN, so this is using the “Onboard Rules” feature. If I did want to datalog the session, I would have to plug in to my router (which in this case really is not more than 10 feet away).
