Process:

This project was the second revision of the previous project; I'm here. It is a machine that produces air and is activated by human movements, such as entering a room. The machine stops producing wind breath- once the person notices the air and responds with a blow. Initially, The structure aimed to be built behind the wall to be invisible like the spooky entities. This experience was created using multiple input and output modules. The PIR sensor can detect movement within approximately 10m of the sensor. The machine produced a puff of air with the help of a blower and a relay to control the air movement. To stop the airflow, I utilized a flax sensor to detect it.

Following the initial demonstration, there were significant changes made to the physical form. Firstly, the two parts were separated, and their shapes were concealed within kitchen objects for camouflage. The first object, named "Puff," was designed to resemble a cookbook and create the Goddess's breath. The second object, "Oven & Fire Blow Pipe," pays tribute to the wood-burning stove, which the Goddess reveres. A wind fan was incorporated into the fire blowpipe to add an entertaining element and indicate where to blow air.

After three parts were set, the inner constructions and each component's interaction. The sensor for the Puff has been changed to an ultrasonic distance sensor to detect the user better, as the previous PIR sensor was too sensitive to any movement and unsuitable for the exhibition. The 3D printer prints the exterior, and the pages are laser cut due to the long 3D printing time. Since the size of the book was large, two parts were printed and glued together.

The Oven and the Fire Blow Pipe communicate through Bluetooth. The Fire Blow Pipe has a wind sensor to detect the wind speed, and it is the central device. Then the Oven received the data as a peripheral device and changed the brightness of the yellow light. It is also connected with the DFplayer with the fireplace sound, and the volume of the sound should be enlarged while the brightness of the light. Unfortunately, the speaker and the DFplyer's instability were not powerful enough. The Bluetooth speaker was used in the exhibition to create the sound effect. Due to the sequential play on the Arduino code, the default flame was independently controlled with the Arduino Pro Micro.
