Arm Alarm was designed for use by individual who are under medical advisement not to raise their arm above shoulder lever. 

Technical Specifications: 

Step 1: Gather materials.

  • Anti-dozing driver alarm aka nap alert (under $3). The device used for this project was a driver nap alert which is designed to fit over the ear and buzz if you nod your head forwards too much.
  • Velcro 

Step 2: Attach to shoulder

Simply attach (via Velcro) the nap alarm to your arm so that it triggers when you raise your arm to the maximum allowed height. Note the orientation from the photograph. It's important that the alarm is facing the correct direction to trigger as it is rotated upwards. Attach a square of Velcro against the larger part of the device, and a thin strip to the ear piece so that it is attached to your clothing at two places, otherwise it is liable to flop over. Note that this is just a 1-axis tilt switch, not a 2-axis accelerometer, so it might not alert if you extend your arm sideways, only if you raise it in front of you.
