4M: New 3D MEMS Motion Tracker

We're working on developing an electronic personal trainer. When we started, we couldn't find an easy to use, plug and play system that could collect all the data and give us the measurements we needed... so we built one ourselves.

It's comprised of three 3-axis MEMS sensors to provide 9 channels of data, an onboard Parallax microcontroller, rechargeable battery system, and bluetooth module to make a complete 3D tracking system. We're using Propeller Tool V 1.3.2. Is anyone else out there working on motion projects that could use something like this?

    Hi piduino. Sounds very interesting. Do you have any more information such as size, recorded data rate and format, and cost? Maybe a picture or two? Do you want to manufacture the device?

    Hi SRLM - tech specs and a photo of the sensor and app below. We're launching a kickstarter in a couple of weeks. From there, after meeting our fundraising goal, we'll move on to manufacturing. Here's a link to our campaign ... feel free to follow to get notified when we launch! http://bit.ly/1bkpJtF

    Hi piduino. I like the small package, and your commitment to open source. Your Kickstarter says "The firmware is also available at www.enfluxmobile.com.", but I can't find it. Do you have a link to your repository that you can share?

    This looks very interesting.

    One thing I'd really like is a direct wired connection to the device that isn't USB. Some sort of TTL or 3.3V logic output at an adjustable baud would be high on my list of features. I wouldn't mind (much) if I had to solder my own headers and cut a hole in the case but I don't want to have to deal with USB or Bluetooth if I were to use this device in my robot. I would accept that adding said headers would void the warranty (if there is one).

    I'm looking forward to finding out the price.

    Good luck with the Kickstarter.

    Edit: I almost forgot, this has a Propeller! If the Propeller code were open source, the odds I'd buy one move up to 99.99% (from 59.99%).
