For over a year I’ve been working on a meditation wearable. It measures biometric and environmental input. Its goals is to use the measurements to improve your meditation and use the data to generate artistic visualisations. The wearable is part of a bigger project Hermitage 3.0, a high-tech living environment for 21st century hermits (like […]

xbee hello world!
Today I’ve had my first success with communicating between two Xbees. Mostly thanks to this simple but clear tutorial. After installing the XCTU software with Thijs a few months back I had forgotten quite a lot of his private class “introduction to Xbee”. From his instructions I ordered 7 Xbee antenna’s and one Xbee explorer […]
device and software
I’m currently developing the device design and the software for breathing_time. I realise now that the form factor of the device must come from the possibilities of the wind sensor. It works best when the breath is guided to the sensor. That way I can detect inhaling and exhaling. I’ve been trying out different sizes […]
wind sensor demo
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 […]
breathing device
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 […]
Ups and downs
I’m having a hard time with my wearable. There are different areas where I’m experiencing problems: – The thermochromic ink deteriorates very fast. Under influence of UV radiation for which I haven’t been able to find a solution. The amount of electricity it needs to heat up is very much depending on the air temperature. […]
Hardware integration
On the photograph you can see the 5 volt circuit. It houses two sensors and two buttons. At the workshop last Saturday I put together button circuit, if you press the white one it means it smells good, the brown one indicates it smells bad. This is of course just a functional setup, purely for […]
Building a heart-rate sensor with Richard
Date: 20-06-08, present: Danielle & Richard van Bemmelen I asked my friend Richard to look at the instability of our current heart rate sensor. Richard is a programmer and engineer so exactly the right man for the job 🙂 It was kind of hard to analyze the current device as everything was soldered together. But […]
