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 […]
trello, a great project tool
I’ve discovered a great tool to manage my breathing_time project: Trello. It’s a free on-line tool for managing tasks. It’s really easy to work with and it has greatly cleared my head in 30 minutes. You just create a board for a project. Add a list (project part) and fill that list with tasks (cards). […]
designing visualisations
Done some first visualisation sketches for breathing_time. I keep coming back to the ink metaphor. But now I’ve made the connection with the Zen calligraphy tradition of ensō. It’s fascinating and beautiful and has of course a close connection to breathing and attention. I did a quick mock-up in Flash: It has potential.
analogue input
Today I did a little test using analogue input for my LED. I build my third RBBB today and wanted to take the LED output a little further. For my breathing device it will have to respond to the analogue input of breathing. So I emulated that with a light sensor. Covering the sensor less […]
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 […]
breathing device design
I’ve been doing some research and sketching for the breathing_time breath detection device. It could take the shape of piece of clothing or lean more towards a device/tool look. I’ve explored the possibilities: I think the wearable variation is a bit too much: As air is such a subtle, immaterial thing I want to underline […]
hardware progress
I’ve made some progress with the breathing_time hardware. Together with Richard (I was his ‘lovely assistant’) we soldered all the parts on a compact board. It will be much easier and more wearable to work with.
fast breathing
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
breathing sequence slow
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 […]
