Hi, my name is Avye and I’m 14 years old. I’m a coder, maker, workshop leader, girl in tech advocate, and the founder of Girls Into Coding (GIC). Through GIC I create opportunities for girls to explore coding, physical computing, robotics & 3D printing.
Project Particle Pavilion
For my project, I've decided to explore how spaces can monitor & react to internal air quality in order to improve the experience of the users.
I think there are a range of spaces that could benefit from this, including classrooms, maker spaces & eating areas in the hospitality sector, to name just a few.
Since the pandemic, social distancing along with the need for additional space and appropriate ventilation has become hugely important. Because of this, I want to also explore the concept of a POP-UP Pavilion - A pavilion that could be installed in different locations to provide space & indoor air quality solutions where needed.
As mentioned earlier I’m a workshop leader, and I create opportunities for young people, particularly girls, to explore tech, so I hope to be able to develop a version of the Particle Pavilion to be used as an educational tool for future workshops
Scale & Hardware
Ideally, my finished ‘Particle Pavilion’ will have a footprint no bigger than A3 (for now) and will be made from laser-cut pieces of plywood & acrylic, the different mechanisms used will involve stepper motors & servos, and will be powered by an ESP-32 or a Raspberry Pi.
Pavilion Ideas / Sketches / Models
- Neopixel inside of the pavilion that changes colour to indicate different co2 levels – alongside some sort of audio alert.
- A sliding skylight opens when a specified co2 level is detected. Possibly using a servo with a linear actuator
- Vertical Shutter wall that will open & close in response to different co2 levels. Possibly using a stepper motor or servo. Will need to explore making different mechanisms/linkages to get this to work.
- I like the idea of using a fan or air purifier which switches on at a certain co2 level. However, I will need to think of an interesting way to include this in the Pavilion idea.
Vertical Shutter Idea / Sketch Models
Which of these will I use to get things moving & how?
