On Friday 25/07/08 Richard and I have worked on the sensor. The makeshift one was too unstable to give reliable results. We used Barbara’s felt prototype as a starting point. It soon became clear that the stiff wires we used didn’t go well with the soft felt. It’s hard to wear the sensor around the […]

Meeting 22/07/08 @ Anja’s studio
Meeting at Anja’s studio from 15.30 – 20.15 Present: Anja, Barbara, Danielle. We met up to discuss the design of the sensor on which Barbara had been working. She’d made a few prototypes with black felt which are very promising. They should be worn around the tip of the finger and can incorporate the parts […]
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 […]
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 […]
Meeting June 6 2008 in Breda
Report of the meeting at Danielle’s place in Breda from 11 to 15 hours, 06/06/08. Present: Anja, Barbara and Danielle. Ideally we want to do the sensing inside the material and not with separate sensors. There is sensitive foam which responds to stretching and pressing. It is used to measure breathing, shoulder movement and shoulder blade […]
Heating
I’ve done a little research into heating elements. As stated in the book ‘Pysical computing’ the firm Minco has a wide range of heat sensors and elements. Interesting are the flexible sensors and elements. Both come in very small sizes. The sensors can measure very small temperature differences, I’ll seen numbers like 0,04C. Here’s an example: Polyimide […]
Meeting 04/04/08 @ Anjas’ studio
Meeting at Anja’s studio. 04-04-08 from 11 to 15.30. Present: Anja, Barbara (till 14.30), Danielle. Barbara has done research into the chakra’s but found the possibilities limited (one line) and the appearance too esoteric. So we’ll have to choose the area’s we want to work with ourselves. We may use some of the underlying theory […]
Meeting 12/03/08 @ Anja’s studio
Our first meeting after the workshop. From 11 a.m. to 4 p.m. Present were Anja, Barbara and Danielle. We started off by rethinking the project: Is it necessary for our project to work with pressure points? Working with them is very precise work that has to be done by a human to be effective. Maybe […]
