Heartbeat Straight Jacket

June 4, 2009

An EL project that displays one person's heartbeat on another person's costume.
  • Thanks! Looks pretty good. I’ve upvoted this and will include this in the batch to test.

  • I welcome anything that will help people learn but to enter it has to be a functional program. If you can post your mathematical approach you might find friendly folks to help you convert that to code. Honestly, one of the hardest parts for me is this step - I’ve found various academic approaches to the problem only to be bogged down when I tried to wrap my head around converting the formulas to code.

  • ShapeShifter nailed it. Sorry for the confusion. Sensor is mounted (screwed) to the top of the platform, mostly perpendicular to the surface of earth.

  • Hi Chris - Sorry for the ambiguity. The MMA8452Q is sitting on top of and is screwed to the wooden platform from which the bag hangs. The idea (of this particular project) was to create a thing that anyone could screw or stick to the top of the platform and get hit counts, without modifying the bag, hinge, or platform (other than attached said magical box).

  • Is it possible? Oh ya. I’ll dig back through the logs and notes and see if I can get anything to line up but if you’ve got an algorithm (and it looks as tho you do) please post it. The proof is in the demo ;)

  • Hmm, neat! A Piezo Trigger is a very cool thing that I did not know existed but in this case we’ve got accel data. But knowing what other tools are out this is valuable as well. Thanks!

  • There’s a series of ways to tackle the problem. The mic is a very cool approach I had not heard of (pun intended). IR is how speed bags are currently counted. I’ve also seen some folks trying to modify the swivel with a photogate, reed switch, etc which becomes finicky. For this particular project my vision was for anyone to walk up to a speed bag platform, screw down a thing, and get counts without need for adjustment or calibration.

  • Yes, you are correct. Sorry, the log explanation is a bit buried in the repo: you can find it here. Additionally I’ve updated the dataset zip to include a readme that breaks down the x/y/z.

    Z is negative at approximately -512 which is 1g or earth’s gravity pulling down. The X and Y axis are not quite zero because this is the physical world and things are not quite level.

    Oh! What an excellent idea. I will probably twist the arm of the winner to give a lunch on learn at SparkFun. These are lunch presentations about hacking, building, etc. The last one was with Even Booth on his Terminal Cornucopia work as well as his work converting a Kuerig into a prosthetic hand. Amazing stuff.

  • You pinned the bug down (thank you) but I respectfully think the fix is different.

    This stays as it is:

    float currentSpeed = get_wind_speed(); 
    

    However, this line inside calcWeather() goes away:

    //Calc windspeed
    //windspeedmph = get_wind_speed(); //This is calculated in the main loop
    

    The reason is because in the main loop we do all our gust detection and recording. If we use your solution you would be testing against the previous reading instead of the most current reading.

  • Good eyes! Fixed.
