Behind the scenes: “Blåfrost 2016”


This is a behind the scenes post from something quite technically manageable, and at the same time visually very powerful!

The case is an interactive installation that turns on the lights and starts up the internal smoke machine whenever someone is nearby.

The poster were printed on a wooden sheet and the biggest graphical elements were removed with a CNC machine. This created several openings in the poster where the spooky light-coloured smoke could escape.

The control system

The system was rather simple: A PIR sensor connected to an Arduino that controlled the LED strip and the state of the smoke machine through an external relay board.
