I am artist using telecommunication. We are working on this artwork called CONTACT:
"Two copper plates, located in two countries. One in Antarctica and the other in Europe.
When one is touching the plate of one country, the other plate warms up."
We have several problems:
1- Pd-0.39.2-extended-test5 is not lauching on a MAC OS 10.3.2
2 - we do not know how to operate an electronic relay with ARDUINO interface
3 - we would be very happy to have an electronician drawing us a electronic map to warm and cool a resistance threw this system (and not burn the users : -)
