On May 12th I lead a breakout session at the second European quantified self conference in Amsterdam. The goal was to exchange experiences in breath and group tracking and to demo the new, wireless version of the breathing_time concept. I started the breakout with an overview of the previous version. We soon got into a […]
Constructing the RBBB Arduino isn’t as easy as suggested. The manual says 30 minutes. If I don’t make any mistakes (to which I’m prone) I might be able to do it in an hour but no less. After I didn’t manage to get the first one to work I started out with a fresh one […]
This is a sequence of fast breathing. It’s nice how you can spot the difference between the rates of breathing. I’m also very pleased with the planetary feel. See the full gallery on Posterous
I’ve managed to program the first representation of breathing-time. This is a sequence of the way the drop changes when I’m actually breathing while wearing the stretch sensor. The dept of the breath determines the diameter and alpha value of the ‘drop’. The breath rate determines the blurring and horizontal position of the drop. Slow […]
I’ve upgraded my code for the stretch sensor graph in Processing. The sensor outputs numbers. When I breath in or out the number gets lower. Detecting breathing activity isn’t as easy as looking for a numbers below 200 for example. Because over the time of wearing the sensor the whole range of numbers starts to […]
I’ve upgraded the first circuit with the potentiometers and the results look promising. I used the Processing sketch that comes with the Arduino to make a graphic of my breathing activity. I’ve tagged the different regions in the graph so it’s easy to follow the movement of the breath. Btw the circuit is constructed in […]
Breathing with a straw above drops of ink.
Four stains made with four drops of ink for each breath taken over four minutes. (I’m a very slow breather.)
