Solar Rim Dress version 2

New version of the solar rim dress (for version 1 see this post:
added mainly white lines to accentuate the shapes.
Builded the lines on the asymmetry of the solar disk on the right side.

The rim of the solar disk is scanned, using a picture of NASA which is updated every minute.

Using Processing the solar rim is coded into 64 spots, which can be bright or dark. The information is sent to the dress using two transceivers (Jeenodes). Because the sun is rotating relatively slowly, connecting to the dress once a day is sufficient to have the activity of the suns rim displyed during the whole day.

Elastic heating pad workshop at Elasta Belgium

For the ArcIntex – TIO3 symposium we did a workshop at Elasta in Belgium, working on elastic heating pad’s which could be made by the machines of Elasta.


So during two days the five of us, Eef, Martijn, Delia and Karen explored possibilities of mixing elasticity and conductive wires.

One of the results was an elastic band containing both heating wires (low total resistance of 10 – 20 Ohm) and high resistance wires. The former heating up, the latter used as a stretch sensor.


We prepared heating samples with a simple sewing machine. Then the genius of Elasta incorporated the conductive wires into the machinerie and it was woven around rubber centres.

Seeing the machines at work is impressive! (And for the future i’ll more admire simple woven elastic bands.)

Some pictures:



Preparing the experiment and testing the sewed sample.


direct commercial success: a workout device with rewarding thermochromic effects!



Machines, the bobine with conductive thread looks a bit small…
