Yesterday we managed to get the first wind sensor working. Together with Richard I connected the sensor to the RBBB board, calibrated it and read some wind/breath data from the serial port into Processing. It works surprisingly well: I have already noticed that the distance from the sensor to the nostrils is critical. I’ll have […]

OOP Processing
For my breathing_time project I’m currently developing a script that’ll represent breathing-time. It’s my first attempt at object oriented programming (OOP) in Processing and it went rather smoothly. The pictures are the first results using static data. Now I’m working on the ‘drops’ being affected by the data from the breath belt. Size, blurring and […]
discovering breath
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 […]
stretch sensor visualisation
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 […]
Win some, lose some
I’ve been working really hard the last weeks. I’ve started to develop the Flash web application. I started with the calendar part which gets all the different days from the database and presents a nice, scrollable and selectable list of days. The user can choose from which days she wants to see data. They are […]
Lost my tracks
Yesterday I discovered something very disturbing. The XML file with the GPS track was missing 40 tracks in the log for the fourth. Not at the beginning or end but just, somewhere…?! This file has thousands of nodes and is almost 1 Mb big. A node looks likes this: <trkpt lat=”52.387110000″ lon=”4.909017000″> <ele>48,5</ele> <time>2009-01-05T07:46:35Z</time> </trkpt> […]
It works!
I’ve made myself very happy tonight. I decided to write the code that invents the data from the Suunto watch, that was lost yesterday. I wanted the date and times to be right but the beats per minute would just be 10 everywhere. The strangest thing happened when I was programming. I didn’t understand quite […]
Format data application
Today I finished my program for combining data from different files. There will be three different files at the end of a day. A text file with lines and tab separated data containing all the data recorded by the Suunto watch. A gpx file that contains GPS data in xml format. And a text file […]
Meeting at Barbara’s
26-06-2008 from 11-15.30 @ Barbara’s, present: Anja, Barbara, Danielle (from 11:45) We had a great time testing the new heart-rate sensorand combining our results into a graph. Our heart-rates varied from 61 to 84 (we had the Suunto watch as a back-up) but although the graphs looked very different when we counted the dents the […]
