The internal clock of the Attiny is quite sensitive to the temperature of the chip.
We made a setup with two Attiny85 microcontrollers with the same code generating a 100 Hz square wave.
The output pins of of the two Attiny85s was connected to the terminals of a speaker.
By heating one or the other Attiny the frequency changes. It is very audible, how the two square waves goes...
As part of the Skab din by project, in collaboration with IdemoLab, DELTA, Henrik Svarrer Larsen and The Emerald String Trio, we created The Ønskekanal + The Wish Canal where you could write your wishes for the harbor on a piece of paper, and assemble a wish vessel. The wish vessel is a test tube with a package of LEDs, copper tape and batteries. When the vessels hit the water, and move in the...
Testing the filling and venting of air through hoses.
The air is both let in and let out through the yellow hose.
First section shows the air being let out, and the barrel sinking.
Last section shows compressed air being forced into the barrel making it surface quickly.
A yearly event held by illutron, KulturSYDhavn brought together various creative groups in the Øresund region over a three week period called "Remixing the Physical" where we experimented with light, sound, water, robots and fire to create new projects. From 5.-7. August we held a festival called KulturSYDhavn where people visited the illutron barge and learned about the projects and work that...
These bouys where build for Skanderborg Festival in 2009. Since, they have been bobbing around in the water next to the ship. Subjected to rain. Washed over by waves. Encased in ice during winter. 2 years have past. Status: Still going strong. Arduino board + cooking oil keeping the electronics fresh.
