Here it is: a box, yes, ladies and gentlemen, a box that can read your pulse and displays it visually as well as auditory. All of this in one simple box. The wireless aspect is still to come, this is the 1.0 version – wired. Look for the 2.0 wireless version next Xmas. top view: […]

After much testing and frustration, from hacking a Polar sport wireless heart rate monitor to a Tanita health monitor, i’ve come back to DIY . Hacking can be more pain than its worth. So I’ve strung together an IR emitter/detector with two resistors with a little help from my friends at these are attached […]

I am creating an auditory feedback device for heart rate monitoring. Using a heart rate sensor as an input into a microprocessor (might need an op-amp to boost signal), the values will be translated into two slightly offset sine wave frequencies as well as two pulsing (PWM’d) LED’s. The higher the values, thus faster rate, […]

Midi is fun …. once you get it going. A lot was un-said about getting this up and recognizing each other, board and computer, such as downloading drivers. Luckily we are all friendly helpful people in the lab. So once i got the lab assignment working it was time to improvise and make some sounds. […]

As you can see, not much is happening. I’ve been able to power up the lcd, have it blink and display text, and even have that text blink, but not much else. Now I’m at the next hurdle of how to go beyond text and character display. So i’m looking for a cheap monotone graphic […]

First test proves that it does work, however, the fsr input at set needs a larger buffer as the mat is too sensitive. As the cat shifted his weight or lifted his head to get a better bite, the frs valuaes would change more than predicted and the lid would close down onto his head. […]
